Modified and revalidated our Bitmapped Fonts
library page.

This page is largely obsolete, having been replaced
by newer code in our Fonts & Images library page.
I've kept it as a historical archive.

Specifically, our newer Bitmap Typewriter creates
ultra high quality bitmap lettering on the fly. And
works with any PostScript font in any pixel count size.

This eliminates the neet for individual instances of
each and every pixel count in each and every font.

A revised Fonts & Images should appear in a few days.

A reminder that Linksys modems and wireless modules
had a heat problem that could cause slow and erratic web
responses after long use times.

Newer units have slightly larger ventillation holes, although I
suspect they are still too small.

Workarounds are to put the unit up on blocks so there
is a minimum of one inch of clearance off the desk. And
to NEVER stack units or put papers on top of them.

The problem with Captain Video is simply this: They
are "for real" our goodwill ambassadors to outer space!

Along with Roller Derby and Kukla, Fran, and Ollie.

In 1949, our sun suddenly became a radio star, blasting
out vast quantities of new VHF energy. In 60 years, this
has swept out one million cubic light years of space and
has been sent to roughly 2700 candidate star systems.

And still at a sensitivity level detectable with our
current technology. And new candidate star systems are
being contacted at a cube law rate, while the energy
levels are only dropping square law.

What if...

What if a candidate star system receives a perfectly
lucid twelve second clip of "Roller Derby" as the

If you try Googling on a topic that is "too thin", you might end

By far the most popular use of photovoltaic pv solar
cells is in solar power calculators. What is the cost per
kilowatt hour for its electricity usage here?

Let's see. Assume the average calculator costs $5
and fifty cents of that is amortizable against the pv
sensing and charging system. Assume further that
the total lifetime energy consumption when calculations
are actually being made or viewed is one watt hour.

$5 per watthour is $500 per kilowatt hour.

Thus, the average pv user pays $500 per kilowatt hour
for their electricity.
And are happy as a clam doing so.

Additional analysis of the ongoing pv scam appears here.

Our local libraries seem to be in a death spiral and
they do not seem to have the faintest clue why.

Attermpted outrageous new charges are creating
extreme controversy. And,of course, will end up
having the exact opposite of their intended effect.

Many of the concepts of a local library are now
ludicrous. Such as having one or fewer available
copies of information. Or not being open 24/7.
Or requiring that an individual, the document, and
a control freak be physically in the same place
at the same time. Or some items not being immediately

Or the documents not containing links to more detail
and related info. Or totally arbitrary distinctions on what
info is and is not "allowed". Or "read it aloud", language
translation, and similar handicapped aides.

Or even the concept that once scarce info now has a major
big time glut problem

If libraries are to survive at all, they will have to immediately
and dramatically reporpose themselves to the concepts of
unlimited info access and otherwise meeting specific
community needs
. Sadly, I do not see this happening.

Meanwhiile, the reality is that our best local library is

I thought I might catalog some of the prehistoric ag
items you might find while wandering around our
local bajadas...

LITHICS - most any rock that appears to
have been purposely broken. Especially
if distinct from all the other local rocks.

REWORKED LITHICS - Similar rocks that
appear to have secondary chipping. Typically
flakes are knocked off a core. The flakes are
then reworked into tools.

POTSHERDS - Broken pieces of pottery.
Differ from rock by their uniform thickness
and grainy interior. Very rare in ag sites.

TRADEWARE - Fancier potsherds that are
decorated by paint or slip. Often dateable
and strong indicators of trade patterns .

MULCH RINGS - Circular rock groupings
typically three feet in diameter. Often found
as a dozen or so in a spaced group. Likely
used to retain moisture for a single agave.
Sometimes wrongly called a "cairn".

ROASTING PIT - Similar rock groupings
somewhat larger in diameter but always with a
distinct internal depression.

CHECK DAM - Small semicircular rock
arrangement across a drainage. Forms a
small upstream "field", often five feet square.

APRON - Secondary rock structure below
a check dam, apparently to prevent erosion
by slowing water overflow .

CANAL - Often looks like a very smooth
hiking trail. Always flat with a very slight
slope. Very long. Purpose oriented.

LINEAR FEATURE - Rather long and
rather straight low rock wall across a
gentle slope. Forms an upslope field.

TRINCHERA - Definition varies.
May be a longer and not as straight
low rock wall used for water control.
Often associated with steeper slopes.
Easily confused with CCC boondoggles!

GRID ELEMENT - A rectanglar low
rock border, typically twelve by twenty
feet across a usually gentle slope. May
rarely have a single mulch ring in the middle.

GRIDS - A grouping of grid elements.
aranged side by side or sequentially
up slope. Tens of thousands (!) of these
appear to be locally present.

FIELD HOUSE - Single rectangular
group of higher rock walls, typically six feet
square. Always at an ag site when present.

HABITATION  SITE- Multiple rectangular
grouping of higher rock walls. Often associated
with potsherds and trash dumps. Almost
always destroyed by extensive pothunting.

Normally somewhat distant from ag sites.

The number and stunning variety of "off the bajada"
prehistoric ag sites here in our Gila Valley continues to
amaze me
. It is enormously difficult to wander around
outside without finding a new and unexpected one.

Virtually all of our mountain fed streams seem to have
elaborate canal systems whose 13th century engineering
appears well beyond stunning. Some of these exceed
ten miles in length; others are hung on a mesa side
90 feet above the local terrain; and others include
aquaducts that are well above grade. One appers to
have a "three way switch" that routes water to a
triad of wildly different drainages. And flows to this day.

It is not unreasonable to conclude that the 13th century
population may have exceeded the present day one.
an enigma remains: The number of ag sites vastly
exceeds the number of known habitation sites.

As best as is known, the entire system was a giant
booze factory, converting agave into mescal.

Or, alternately the related ag grids were the first instance of
prototypical Dilbert cubicals. The Alice PMS Revolt of 1385
would clearly explain the latter decline in population.

Yet another reason for keeping a very low profile at
any and all auctions:

Bidder "A" has specialized expertise in one specific
group of items and a rep for making a major market in
them. Bidder "B" is a plain old opportunist junk
dealer who does not have the faintest clue what the
group of items is worth or what can be done with them.

Bidder "B" simply keeps bidding till "A" quits. Assuming
he will win the items at only slightly higher than their
genuine value.

A partial defense for "A" is to continue bidding to jack the
price up. But never beyond what a reasonable return can
yeild. A better "A" defense is to never let anybody know
what you know.

If you scan or photograph a partially open bound book,
you may encounter the "gutter problem". In which the
extreme right or extreme left words will be unacceptably
squashed. Besides looking bad, this can prevent OCR
recognition and later full text search.

I've been recently wondering how well and how generally
the gutter problem can be defined mathematically. And
then post processing repaired. Especially with a low budget
and only occasional use.

Let's limit ourself to a left page that is squashed right
and normalize our interest space to zero on the left and
one at the right. While a cubic spline approach may work,
all or our curvature is clearly at the end, and something
maximally flat might be a better route.

Instead, consider a sparse Taylor Series. Such as using
y = ax^b. Perhaps y = 0.15x^7. The value of "a" decides how deep
the gutter is and the exponent desides how soon or how
suddently the curvature will begin. A fairly simple expression
thus gives us a surprisingly good fit to a book page being

The question is now to relate how much the actual page distance
delta-s changes for each horizontal distance delta-x? A small
change in x will also produce a calculable change in y. The
change in s will be their vector sum by the usual square-root-
of-the-sum of the squares. Pythagoras strikes again.

The correction we need will be deltas/deltax. Now, this could
be a function we could again find with a cubic spine or a Taylor
series. Chances are the exact math will involve more terms
and end up a tad ugly. Since it is the inverse of a square root .

Instead, if we think ahead to our upcoming bitmap repair process,
we certainly would want to avoid making a complex math
calculation for each and every pixel on each and every line.

Table lookup comes to the rescue. Simply make delta-x equal
one pixel in your post processing!
And use a fast delta-s versus
delta-x table lookup. Then it should not matter in the least what the
exact formula for the gutter math is. 2000 or so samples should
work just fine.

How well this will all work in the real world remains to be seen.
I'm presently working up some demos and utilities.

Present thinking is to open the book by 45 degrees with a
quality mirror. This should minimize guttering and potential
book damage. Then digitally photographing with a high
pixel count camera to a bitmap. Then rectifying the bitmap
to correct vertical inversion, deskewing, anamorphic
scaling, and deguttering. From there, the usual OCR,
preferably with ClearScan or better.

December 1, 2009 deeplink respond

Book scanning for individuals or those with limited budgets
are dramatically improving.

The high end folks simply project an infrared grid onto the
book pages and then do elaborate signal processing and
distortion correction using a costly system.

But what can be done by an individual on a limited budget
with only a few books or bound reprints to occasionally scan?

Goals of a scanning system are not only to capture the image,
but allow reliable OCR recognition.
The latter both dramatically
reduces file sizes and allows full text searching. Plus possible
later editing, text reading, or other handicapped aides.

New  ClearScan features of Adobe Acrobat have very much
improved image capture for full text search.

These days, cameras are approaching 16 megapixels and thus
are more than competitive with conventional scanners.

Because of elaborate Bayer Filtering, the effective resolution
of a digital camera is not obvious. But 12 megapixels of B/W
or grays should be ballpark for a 16 megapixel sensor. Less for
reds or blues. And processing algorithm dependent.

12 megapixels effective translates to a square array of about
3500 x 3500 pixels. 3500 pixels in eight inches would be a
resolution near 440 DPI. And thus, with careful use of
maximum camera areas, should be more than good enough
for book scanning.

We should now have enough "excess" resolution that
elaborate image processing can become the norm.
Such as deskewing, "deguttering", image reversal,
or anamorphic size adjustment.

One possibility is to open a book by 45 degrees and place
a quality mirror in it. Illuminate the mirror from a uniform
diffuse source and digitally photograph the reflected
image. Then use image processing to rectify and invert the
image to its intended "flat" and "aligned" state.

Org. Got yet another email from someone about to
revolutionize electrolysis and would I please recommend
a highly qualified yet low cost electrochemist within six
blocks of Holt County, Nebraska.

One more time: There is a profound and fundamental
first principle of thermodynamics called "exergy" that
absolutely and positively GUARANTEES that electrolysis
from high value sources such as grid, pv, wind, or alternator
flat out ain't gonna happen.

The process would be exactly the same as 1:1 exchanging US
dollars for Mexican Pesos. There ALWAYS will be more
intelligent things to do with the electricity
than immediately
and irrevokably destroying most of its value.

Just for kicks, try finding an electrolysizer manufacturer
Even if you find one, they certainly will not tell
you how much their products cost, and absolutely will not
sell one to an individual because of safety and liability
issues. The reason being that exergy limits such devices
to highly unique, specialized, and obscure industrial uses.

Virtually all bulk hydrogen gas is produced from hydrocarbons.
The amount produced by electrolysis is utterly negligible and
limited to exceptionally specific needs where system efficiency
and costs are not major design factors.

Exergy is a measure of the present quality and value of an
energy source.
You measure exergy by converting that
source to another form, converting it back, and seeing how
much you have left. Resistance room heat is a classic
example of horribly wasted exergy.

Electricity is about the highest exergy stuff available. Unstored
hydrogen gas has exceptionally low exergy. Electrolysis is the
process of converting many high value kilowatt hours of energy
into fewer very low value kilowatt hours of energy.

And, thus, is normally and monumentally stupid.

As such, electrolysis clearly will forever remain totally incompatible
with efficient and sensible alternate energy solutions

And that is before abysmal system efficiencies, amortization, or
stupidities ( such as stainless steel electrodes with its hydrogen
overvoltage of iron ). "Real" electrolysizers demand platinized
electrodes that are regularly renewed.

Does exergy mean that solar to hydrogen via Faraday's Law
is never gonna happen? Not al all. But it does GUARANTEE
that conventional high value electricity will definitely NOT be
a mid process energy state.

Once again, our bottom line summary:

    If you do not understand exergy, you SHOULD NOT be
    pissing around with electrolysis.

    If you do understand exergy, you WILL NOT be
    pissing around with electrolysis.

Either way, the outcome is not the least in doubt. More can be
found here, here, and here.

It turns out that the theoretical energy recovery

While a fairly clean technology, infrastructure costs and
membraine lifetimes may or may not make the concept
viable. The usual problem cited is that a lot of brakish
water is produced that could demolish local environments.

Another factor that nobody seems to mention is that,  (since
perpetual motion is a no-no ), if you are going to recover some
high exergy, high quality electricity, the value of energy
released elsewhere has to decline by at least a comparable

This says that if you have river A emptying directly into the
ocean and river B doing an osmotic to electricity conversion
and then exiting, then river B has to exit colder!

I find it both gratifying and rewarding when a single

gets trashed. This easily could be CIBC in drag, in which a
bubble containing air and hydrocarbons collapses and increases
in pressure and temperature beyond its ignition point.

Over on the pseudoscience side of the fence, two of the
more persistant and more enigmatic claims might also be
explained by the same CIBC phenomen.

Ever since the 1950's, there have been recurring claims
of "superefficient" electrical heaters based on an apparently
cavitating oil. CIBC could provide a credible explanation
for the rarely observed and obviously difficult to duplicate
effect that is totally within the bounds of "real science".

Another more recent fantasy development is called the
"Clem Engine" which has all sorts of overunity claims
associated with it. A Clem engine involves possibly cavitating
vegetable oil and, once again, CIBX could provide a credible
explanation for the observed anomolies.

A reminder that the NASA paper's mention of the possibility
of "net energy production" simply refers to getting above
an efficiency of ZERO.

More on bashing pseudoscience here and here.

This NASA Paper suggests a possible new thermodynamic
cycle with possible energy conservation and pollution advantages.

The process is called CIBC, short for Cavity Ignition Bubble

It is based on sonolulminescence which we looked at here and
here. A collapsing cavitating buble generates astonishing temperatures
and pressures. But still ( as far as we know to date ) not even
remotely near what is needed for true fusion.

Instead, what if the bubble contains a stoichimetric mix of a
fuel and air?
The collapse raises the temperature beyond
ignition, Diesel style. The thermodynamic efficiency can
in theory be well beyond the best of known engines.

The best the paper is willing to say is that the effect appears
to be real. And that it appears to have the potential of net

Note, of course, that net energy here would be defined as
anything above ZERO efficiency,
and not anything in any
manner overunity. Long after you overcome the need for
sonic sources and compressors, you still have to have
enough excess energy to compete with conventional
fuel thermodynamic cycles.

One developing company who may or may not be valid
can be found here. Their interest among the overunity
makes them somewhat suspect. Time will tell.

There's a flap on one of the newsgroups over a steam
automobile engine. Yes, steam does offer each stroke
being a power cycle. And delivers torque at zero speed,
largely reducing most needs for clutches or transmission.

And, yes, the primary reason steam autos folded was
hoof and mouth disease!  Seems that all the public
horsetroughs were emptied just as gasoline technology
was gaining a toehold on its production learning curve.

BUT -- Cylinder style steam engines were abandoned
half a century ago, because their best efficiencies were
in the one to ten percent range. Modern multi-stage
bottom scavenging utility steam turbines now approach
sixty percent (!) thermal efficiency.

Other major issues with steam include that condensing
is manditory
to reduce water loss and corrosion is
outrageous. Even with force at zero speed, some
torque conversion would likely still be required. There
are also startup times and boiler safety issues.

Hollywood nonwithstanding, it is enormously difficult to
instantly release all of the energy in a gas tank in a
short time
. But utterly trivial in a steam boiler.

There is a tendancy on newsgroups to confuse instant
paper designs with actual products. Often combined
with a failue to understand the background and history
of the technology being bandied about.

A summary on current Magic Sinewave status:

Magic Sinewaves are a recently discovered math
technique that let you digitally synthesize sinewaves for
such things as industrial motor controls, electric autos,
or solar panel synchronous inverters.

Key features of a magic sinewave are that they let you
zero out ANY number of low harmonics and do so at the
highest possible efficiency
. By their very definition.

A useful summary of the techniques appears here, while
an ultra fast JavaScript Magic Sinewave calculator is
found here.

Important tested and verified magic sinewaves include
Regular, Best Efficiency, Bridged Best Efficiency, and
Delta Friendly. The latter meets the exacting needs of
three phase power systems at a price of zeroing out
fewer harmonics.

About a year ago, I started asking the question whether
some sneaky tricks could further reduce the already small
early uncontrolled harmonics
. In particular, a Regular magic
sinewave has early uncomtrolled harmonics that can be
the exact opposite
in sign of a Bridged Best efficiency one.

Which suggested that dramatic further improvements
were possible. Sure enough, demos of exact cancellation
were easy enough to make
. But sadly, ever attempt at
doing so using obvious half cycle and multi cycle techniques
introduced subtle and nonobvious subharmonics and other
terms. These terms made any improvements marginal at

So, while the current crop of magic sinewaves work like a
champ, the jury is still out out on whether significant further
improvements will become possible.

Some sneaky geometry that can easily cause you grief:
The length of something wound on a reel often builds
up with the SQUARE of the diameter.

Which you can prove with a simple Calculus 101
integration. Exact details will vary a little with the tape
thickness and the hub diameter.

Or intuitively, the count or length per turn doubles with
each doubling of diameter.
Thus the outside turns hold a
lot more than the inside ones.

Thus, a "half full" reel of, say 5000 SMT resistors is
more likely to hold only 1250 parts or so.

Some SMT reels have "0.2,  0.4  0.6  0.8 calibrations on
them. Which for a 5K reel would be 1K, 2K, 3K, and 4K.

The best route towards book scanning appears to be
the "Vee Method". In which the book is opened about
ninety degrees and two separate high resolution digital
cameras ( or one moved camera ) is used to capture
alternate left and right pages.

Regular scanners cannot get anywhere near a book
gutter, while hand held units are highly unlikely to
allow OCR good enough for reliable searching.

The issue of spine distortion remains. Google has an
elegant approach where they project an infrared grid
onto the page and use additional cameras to derive a
3D correction.

Intermediate solutions for individuals only wanting
to capture a few to a few dozen books seem lacking.
Entering some measured numbers per page would
not be a big deal if it only had to be done a few
hundred or a few thousand times total.

Clamping with glomper clips should help a bunch.

I'm wondering if the spine distortion cannot be fairly
easily defined with some sort of a sneaky power series.

Perhaps something like...

                         8 * 0.7 x^8

a full sized page.

There's an obvious fatal flaw in electric vehicles that use
battery exchange stations. I am surprised that nobody
has picked up on it,

Batteries are near certain to remain quite expensive, even
when and if they reach acceptable densities and lifetimes.

With an exchange system, there will be a battery in the car,
a battery being recharged, a battery sitting on the shelf to
meet peak demands, and batteries in transit going from where
there are too many to places where there are too few.

All of which says that each electric vehicle has to pay for
and support at least four batteries
, possibly more. Plus
the costs and profit margins of the recharging stations.

Thus pricing the exchange concept out of the market.

The SIGVIEW folks have recently improved their FFT
Fourier spectrum analysis software.

Our approach to using SIGVIEW with our Magic Sinewaves
goes something like this: We create a 8-bit signed binary data
file of sixty cycles of a bipolar waveform of the desired truncation.

Using $00 for zero, $40 for unity positive amplitude and $C0 for
unity binary amplitude in 2's complement.

Use of 60 cycles makes for a very long ( multi megabit, often 2,499,840 )
file, but it gives exact frequency callouts and dramatically minimizes
any of the usual FFT windowing problems.

To date, the Sigview routines show all of the earlier Magic Sinewaves
working as predicted and described

subharmonics or cosine components that make their potential improvement

As we've seen bunches of times, the general purpose PostScript

as reading and writing any uncompressed diskfile in any language

Per this tutorial and possibly helped along by our Gonzo utilities
and their Gonzo tutorial.

This  FIXAMPS.PSL  latest utility is an "ampersand fixer" for xhtml.
You use it to help revalidate older web pages. The utility finds any and
all ampersands in a file that are not followed within eight characters
by a semicolon and changes them to "&amp;".

This is particularly useful to automatically repair website links that
have lots of semicolon delimiters
in them. As is typical in eBay,
mapping software, and search engines. The routine is swift enough
to not change an already changed ampersand, such as &nbsp; or &gt;.

To use, you bring the utility up in your favorite word processor or
editor and change the input and output file names. Then send the
resaved routine to Acrobat Distiller.

Note that Distiller versions more recent than 8.1 default to a file
writing lockout, so you have to run these from your command line
by using "acrodist -F".

Note also that any single reverse slash in a PostScript string must
be replaced by a double reverse slash to be interpreted correctly.
Especially in Windows filenames.

The utility is especially handy because Dreamweaver has a bug
in it orders of magnitude beyond insidious that hours later into a
session will maddengly change most (but not all) of your ampersands
back the way they were before you fixed them!

There is one known bug: Ampersands within Visual Basic statements
must remain the way they were!
So a manual repatching may be
needed. Problems may also be encountered in a web URL link that
freely intermixes ampersands and semicolons. These probably do
not exist ar all. Or at least are extremely rare.

Oops. There seems to be a major flaw in our GGMS magic

Yes, they can give a complete cancellation of the first group
of uncontrolled harmonics. And yes, they replace them with
much smaller and higher harmonics.

But, at least in the present REG-BBS-BBS-REG scheme,
some odd subharmonics get newly introduced that create
problems. At present, the cancellation gain only ends up
very modest at best.

In which complete and total cancellation of all the "thirties"
uncontrolled harmonics can be observed

major uncontrolled harmonic the 61st at greatly reduced

Sadly, there are new 30 Hertz odd harmonics caused by
the two-cycle cancellation. These can be seen to be
quite significant in the "thirties" region.

I'm not sure where to go from here. Using a four cycle
cancellation should eliminate the 30 Hertz odd harmonics
but likely will introduce 15 Hertz problems. "Shaking
the box" jittering of the quantized data values might
also give some further minimization.

At present, it looks like some schemes will work to
reduce uncontrolled harmonics of GGMS magic sinewaves.

An example of our new tools to create and analyze GGMS
Magic Sinewaves includes the 0.47 amplitude tools found
here for the spectrum, here for the analysis, and here for
the Gonzo sourcecode.

Other techniques may be required for amplitudes above
0.5 and there are some minor issues with amplitudes .48
and .49. Lower amplitudes are trivial with this code.

GGMS Magic Sinewaves are a new development that
zero out twice the usual low frequency harmonics through
a cancellation process.

Here is an amazingly simple synthesis route, usable for
GGMS amplitudes from 0.0 to 0.50...

    bridged best efficiency BBE magic
    sinewave of TWICE the desired
    number of pulses per quadrant.

2. FACTOR this result into a REG and a
    BBE magic sinewave by regrouping
    alternating pulses or pulse edge pairs..

3. Create a TWO CYCLE waveform
    consisting of REG-BBE-BBE-REG
    half cycles.

There are subtle differences between these
REG and BBE magic sinewaves and earlier
ones. Involving cancellations of non-zero
but lower earlier harmonics.

At present, I do not have the faintest clue
how to synthesize higher GGMS ampliltudes with
total and true cancellations. But these most
likely do exist and some sneaky algorithm should
eventually evolve.

I'll try to work up a GuruGram on this shortly.

Please email me any verifications or observations.

May have a major advance in our GGMS magic sinewaves,
following some disappointing setbacks. A magic sinewave
is a newly discovered digital synthesis procedure that zeros
out any desired number of low harmonics using the absolute
fewest number of switching transitions. Important uses are
industrial motor controls, electric autos, and solar panels.

The question came up whether the first few uncontrolled harmonics
could be further reduced before filtering by some sort of spread
  or cancellation techniques.

Early analysis was unduly optimistic because quarter wave symmetry
was assumed but not present.
Which combined cancellation with
newer odd cosine or even sine terms for only an arguably marginal benefit.

Instead, these preliminary results seem to show promise and can give
a very significant reduction at least to certain amplitudes.

Fourier analyze a TWO cycle waveform consisting of REG-BFF-BFF-REG
half cycles. Be sure to note that all resulting harmonics will be double
those of the real world. At 0.53 amplitude, a conventional 8 ppq BFF
has its first uncontrolled harmonic of 0.77 at the 31st harmonic. The
GGMS version has its first uncontrolled harmonic of 0.18 at the 61st
harmonic. That is BEFORE filtering. Filtering, of course, should end
up ridiculously better.

I'll try to work up a GuruGram on this once I have more results. Yes,
there still could be serious math errors, and yes, there could be further
hidden gotchas. Some question remains whether the real world will
tolerate harmonic integration over a full two cycles.

The potential for four cycle integration remains even more intriguing.
Predicted improvement would depend on amplitude.

Please email me with your independent check results.

Even after a dozen trips, I've yet to find exact route
info for the Montez toll road. What follows remains
mostly speculation, backed up with only weak evidence.

The route likely went from San Jose to Guthrie. There
was superb train service from Guthrie to Cliffton, Morenci,
and even Metcalf.
There is one and only one credible and gentle
route up onto Tollgate Mesa from Guthrie. Acme Mapper
shows hints of a route which eventually becomes a modern
ranch road. All of which gets confusing at the corral near the
modern highway.

The northern modern highway cuts just west of the corral show
rockworks at their upper limits. These rockworks have unbroken
ancient desert varnish and may in fact be the toll road. The
positioning of the modern road cuts suggest an attempt was made
at historical preservation.

Things get confusing well before the summit. A ranch road to the south
shows an initial east-west portion that may be the original toll
road. Continuing west along the modern highway, there is little
evidence of the toll road. It is possibly buried under modern construction
or flood damaged. On the other hand, it is fairly obvious where the
route had to go along the bottom of the draw..

The "Tollgate Site" marking on the topo map probably is accurate,
and a fairly obvious stretch of the route can be found further west.
This typically is a twelve foot wide path whose rocks were cleared
to a running wall to the south. The wall was typically a foot high
and a foot and a half wide. Newer water pipes confuse the issue.

The route "had" to intercept the largely disused sothern extension
of the Back Country byway, but it is not yet obvious to me just
where. Probably near the wash "low water crossing". The rest
of the route probably followed old US 70 past what I call
the Unnamed Tank in our Gila Dayhikes library.

This is the only historical record I've been able to find, and
it is an undocumented popularization. Please email me if
you have any better info or field verification.

The HTML <li> list command seems to generate
all sorts of errors when validated to trnsitional or
better modern standards.

This command is "depreciated", which means you
should not be using it in newer designs and layouts.
Use CSS techniques instead.

The main problem is that <li> must NOT be inside
a <blockquote>...</blockquote> structure.
Undo all
of yoour blockquotes and reposition the <li> portion
using the older <ul> and </ul>.

Finding right sized and properly positioned bullets
for substitution can be tricky. There is no bullet in
conventional ASCII, and the ampersand-#183 command in
gives a rather small bullet. And using a
larger font size moves the bullet vertically.

One of our current Magic Sinewave projects is to try
and use spread spectrum or cancellation techniques to
reduce the early uncontrolled harmonics. This is turning
out to be a lot more difficult than initially thought.

Many thanks to Robert Ackerman and others for their
independent checking on this. Attempts to date such
as this, this, this, and this have introduced additional
even sine harmonics or even cosine terms. Leaving
only an arguably negligible improvement.

The original premise was that a regular magic sinewave
and a bridged best efficiency magic sinewave have
their early uncontrolled harmonics that are often equal
and opposite in sign to each other.
The question remains
whether some scheme can be created for cancellation.

Curiously, most any even bridged best efficiency magic
sinewave can be factored into two terms of a regular
magic sinewave of half the transitions and a BBE magic
sinewave of half the transitions. When combined, these
two clearly give a "perfect" loharms cancellation with no
new even harmonics or cosine terms.

The only tiny gotcha is that the number of pulse edges
double, thus reducing the switching efficiency.

There sure is a difference in researching our local toll
roads.The Weech Road up Shingle Mill Canyon was the first
road up Mount Graham. While vehicle impassible in
seven places ( mostly flood damage + a forest service
closure ). Most of it is quite easy to follow, although the
4WD vehicle passible portions are mesmerizingly awful.

Not so with the Montez Road up Toll Gate Canyon.
Only small portions are likely to remain obvious, and
even finding the ends and route are proving extremely
difficult. Flood damage, new highway construction, and
pipelines further complicate matters. Yet this was the
more important of the two routes.

Any hints would be welcome. More on similar hikes

Which you can prove by using This Validator.

Ampersands are a particular problem, in that nearly

Can cause all sorts of problems, especially those from
eBay, Acme Mapper, and typical government agencies.

There are lots of maddeningly infuriating problems with
Dreamweaver. Possibly the worst is that if you use it to
change ampersands to "approved" form, it will change them
all back an hour or two later into your work session.


Which leads to an even more subtle gotcha: Dreamweaver
is swift enough to detect outside program changes and may
ask you if it should do an update. NEVER DO THIS!

Instead, always "fresh load" your word processor just
before your ampersand changes, and close it just after
completion. Then reload Dreamweaver by hand.

Otherwise, Dreamweaver may revert to code you edited
hours or even days ago.

The PostScript status command seems to have two
wildly different and easily confused uses.

When applied to an internal file object, the command
returns true if additional bytes remain to be read and
false otherwise. You can return to reread earlier bytes
using the fileposition command, with 0 fileposition
returning you to the beginning of the file

There is no direct way to find the length of an internal
file object. Instead you have to use...

         dup fileposition exch bytesavailable add

When the status command is instead applied to a filename
string, it explores the presence and condition of a file on the
host machine
. Returning either false or -pages- -bytes-
-referenced- -created- true.

Note that the full pathname is usually required and that
each and every forward slash in the pathname must be
replaced by a double slash
for proper PostScript interpretation.

Note further that Acrobat Distiller versions above Acrobat 8
default prevent writing to host disk files
. You can enable
XP by entering Acrodist -F from the command line and other
systems by following these details.

I seem to be spinning my wheels over trying to improve
the latest version of Acrobat 9. While their Clearscan feature
is quite impressive, it seems to have flaws.

Specifically, I would like to be able to retouch the final fonts
and clearly know which text words are in fact searchible
. I
would also like to improve text in figures and make them
searchible as well.

Essential is an UncompressPDF.api plugin. But I cannot
seem to be able to get the one in the free Acrobat 9 SDK
to work. The immediate rude surprise of the SDK is that
all tools are in C language sourcecode and will need
compiled before you can use them

It turns out that Microsoft has a new and free beta
of their
Visual Studio 10 out that should have the
needed tools.

So far, this generates a "can't use mkdir" postproc error.
Finding the output code in the Debug folder does in
fact let you move a new copy of UncompressPDF.api
into the Acrobat plugins file. And does in fact
add the needed "Uncompress" menu item into
Acrobat. But so far it does not actually uncompress
the .PDF files I'm trying to use

Plan "B" was to go to the free PDFTK open source
software that also includes an uncompressor. So far,
this seemed to install ok, but Win XP will not yet
recognize it from the command line.

Plan "C was to write my own uncompressor using
my Gonzo Utilities. But files are the only sure way
of dealing with all 256 characters and with lengths
greater than 65K characters. There is no stream or
endstream operators in PostScript, so these will
need converted to create new file objects which then
can be Flate uncompressed.

I did find a TypeTool 3 that looks like it should
be able to edit the custom Clearscan fonts.

Please let me know any solutions to the apparent
above problems.

What really galls me over alternate energy solutions is
simply this: Genuine breaktrhoughs are impossibly difficult
to fund and highly ridiculed. While ludicrously and laughably
"not even wrong" obvious fantasies grab the spotlight as
well as run away with the big bucks.

Consider this scheme to replace highways with pv solar panels.
There is so much "not even wrong" with this on so many levels that
I do not know even where to begin.

Clearly, such thinking could only have come from spending long
hours in the outhouse alone. And the epsilon minus government
bureaucrats tha
t funded this electrocity should be staked to an anthill.

For openers, there is no such thing as a net energy pv
Not one net watthour of pv energy as ever been
Nor will it happen till several years after the
net net unsubsidisied cost of fully burdened and equipped
pv panels drops under twenty five cents per peak watt.

Until well after breakeven, each and every panel will
need carefully optimized
if it is even to hope to become
something other than a gasoline destroying net energy

ANY factor that focuses on ANYTHING but net energy
is a fatal flaw.

Let's see. That means the optimum pv farm shape MUST
be a square or at worse a rectangle.
And certainly
not an arbitrarily long linear array. A mile hiway lane
would produce far less energy than two or less acres of
properly designed pv farm. At two or more orders
of magnitude in cost.

That means the optimum pv angle MUST be elevated rather
than flat.

That means the pv panels MUST be carefully protected
from the slightest wear.
Not to mention getting run over
by a truck or freeze expanded. Or covered with snow
and salt .

That means that the sole purpose of the pv farm maint
MUST be to preserve and optimize pv production. And
not worrying about distupting rush hour traffic.

This means that there MUST be something "wrong"
with the pv site that makes it inappropriate for any
other use.
Such as very limited water.

A genuine alternate energy efficiency improving
breakthrough is instead found here.

A fearture that would make Acrobat's Clearscan even
more useful: A built in font editor.

Clearscan apparently makes a new font "A" by averaging out
and smoothing each and every "A" of a given style and size in
the text portion of the document. The result looks much better than
the original ( besides allowing much smaller files and text
smoothing ). But the font still may look a little ratty.

Caused primarily by defects in type on older documents.
Substituting fonts gets tricky because of the character
widths. Especially with fill justification.

But it sure would be nice to retouch the character shapes
with a hand tweaking.
Ferinstance, a lower case "a"
might still be "fuzzy", "weak" or "too open" compared
to modern typography.

Yeah, you can really do this by hand using a print to disk,
compression removal, editing the font in a third party
product, and recompressing and resaving.

Manual font tweaking definitely should be a built in

While regenerative braking is certainly a worthwhile
addition to an electric vehicle, most individuals tend
to grossly overrate its potential and value.

A theoretical benefit might be fifteen to seventeen
percent. Which in the real world likely becomes nine
to ten percent. Minus conversion efficiencies. And
even less with sloppy driving habits.

You can easily prove this to yourself. Find a vehicle
( such as a city fire truck ) that has a retarder on it
and drive it for a while. You'll find yourself continually
"feathering" the gas to prevent the retarder from
kicking in.

The percentage of the time that kinetic energy is
being absorbed is largely negligible.
And you get
the same energy back regardless of how fast the
initial accelleration got you up to speed.

A third party hosting of my "Experiments with WWVB"

The WWVB signal is noisy enough in most parts of the
country to give disappointing results.  Especially with
simple receivers.
And most people failed to pick up
on the significance of a clock that automatically will
self-reset and is always accurate.

These days, we have tuning fork style 60 kHz crystals

greatly improved ferrites are available for a 60 kHz
antenna. And phase lock loops that autocorrelate on
sine and cosine channels are no big deal.

But the really big improvement that could be made
is throwing a zillion computer horsepower at the problem.
We know exactly what the WWVB output is supposed to
look like
for  the next 24 hours. Which means we should be
able to cross correlate with a local reference te to an
effective bandwidth of a tiny fraction of a millihertz!

There are several commercial solutions available off
the shelf. These tend to be pricey and not much in
demand. They usually beat the noise problems by

While it certainly pays to aggressively seek out
each and every upcoming auction that could possibly
be of interest, getting really excited about a new auction

Firstoff, many auctions are never held. They are

The concept of "Lets keep the Cave / Fossil / Ruin / Hike a
secret so the bad guys can't find it" never was a very
good idea. These days, web and other developments make
the concept wildly less than utterly useless.

The first hints that all was not well emerged many decades
ago when the stunning discovery was made that the secret
dirty hippy insider underground publication for everybody
ripping off the phone company was ----> The Bell System
Technical Journal!
And that the key component needed
was included free in every box of Captain Crunch cereal.

Long before the Streisand Effect.

Back then, you actually had to know what a technical library
was and where to find one. And going to a remote physical
location involved several trips and a lot of luck. Rather than
simply saying N 33.16482 W 110.70876. GPS, of course.

Many thousands of people are now routinely into orienteering
and especially geochaching. Making finding any location trivial.
And freely publishing it world wide even less so.

Having the location instantly gives you a topo map and detailed
satellite imagry via Acme Mapper. Or land ownership via
GIS sites such as this one or tax roll sites such as this one.

And most everybody now has ready access to the insider'e
papers and publications. Or shortly will have. Such seemingly
innocuous inclusions as including two foot contour lines on
a ruin site sketch can tell you exactly where the ruin is in a few
minutes of topo searches. As can fitting two bends in a stream.

Doing your own low cost aerial photography has become
trivial, and shortly should approach super cheap.

As with such stupities as DRM or copy protection or draconian
NDA's, there always will be more bad guys than perceived good
And they always will be smarter than you and always will
have accesss to more research materials and more time to
patiently explore nonobvious links and obscure source materials.

Yet another approach involves the Freedom of Information act.
But this route instantly brands you as a bad guy and draws
attention to yourself.

So, excessive secrecy is almost always totally pointless.
Besides usually having the exact opposite of its intended

One possible solution is not drawing attention to something
By not being that way in the first place. A second
is to actually trust people who, on the average, are likely to
benefit your research

put nonspecific but unique names on stuff that does not hint
on their location, but exactly tell you how "they" found it.

Some tips if you are planning your own hot tub:

It should neither go outside nor inside. Instead, provide a shelter
or well ventillated semi-building. Outdoors has problems with
uv degradation, dust and grime, convenience, privacy, and
heating costs. Existing indoors can cause mold and mildew,
rust, and excessive humidity .

Atriums or other plant intensive structures work well.
Good ventillation and separation from living areas are
both essential.
Isolation from the coldest winter
temperatures is also recommended. Either through
thermal mass, insulated walls, or actual heating.

The usual biggest tub size is 6 foot 8 inches, because this is
the largest size that will fit through an Arcadia door frame.
The door itself may have to be removed during installation.

While the tub itself is usually a ready-to-go dropin, a rather
expensive electrical installation is normally needed. 220 vac,
with manditory higher quality GFI. A low voltage safety
control loop and a timer is strongly recommended. A
professional electrician is usually essential.

A fully insulated cover is a must. It is also important
that the underside of the tub be spray insulated. All but
the cheapest tubs now usually include this feature

Hot tubs are quite heavy when full. Putting one on
the third story of a hundred year old home can
lead to rude surprises. 500 gallons of water is
around 4000 pounds or two tons! Plus people weight.
Your installation is best done over a reinforced
concrete slab. The tub must sit flat on its bottom
and never supported by any edge lip!

Most modern tubs are quite deep. You will need a
companion deck or ladder or whatever to conveniently
be able to step into them.

Solar heating or solar boosted tubs are usually
not remotely worth the hassle and inconvenience.
The confort temperature zone is quite narrow.

Retail markups in the industry are outrageous, so
always shop around. Older or used tubs can be bad
news because of cracking or crazing. And tub
refinishing is a highly specialized task that almost
certainly will be screwed up by any local fiberglass

Had a controller go out on our hot tub. The most
likely cause was excessive humidity getting to their
piezo switch sensors.
Two of the four switches
failed, the first one intermittently at first.

Hot tubs have improved dramatically recently.
But I still like those classic custom octagons that look
better architecturally, are easier to get into and
out of, and hold more people.

Everything essential is usually built into the tub
these days. A combination controller and heater
talks to the control panel via a RS422 Ethernet
type comm loop.
Apparently they did not use
a conformal coating on the controller or otherwise
prevent a humidity attack. Long after the warranty
was up but still an unacceptably early failure.

Balboa is a leading wholesale supplier.

The technology still has problems. It is usually
tricky to remove the final 20 gallons of water
A waterfall pump or a shop vac can sometimes
help. Siphoning usually does not have nearly
enough head. Tubs are typically filled from a
garden hose, rather than needing an actual
plumbing hookup.

An external windup or electronic timer can
significantly reduce your operating costs.
Even better if it is computerized and can anticipate
your warmup times. Perhaps using some sort
of table lookup to deal with ambient variations.

Electrically heated tubs are quite convenient but can
be very expensive. Eight kilowatts of heater for two
hours per day translates to fifty dollars per month.
And possibly double that if you are sloppy about
your lid covers or do not use a timer.

Curiously, using a tub every day costs about the
same as every second day.
The reheating costs
are surprisingly comparable.

There is an obvious solution of a heat pump.
While there is no particular reason that these
should be expensive, they typically will double
your installation cost today and are in no manner
cost effective.

As we have seen, "contents of cabinet" ond especially
"contents of room" auction lots can be exceptional bargains.

But it is super important that you view the lots and know
exactly what the room or cabinet purpose was.

Ferinstance, a maintenence stores should have all new or
nearly new stuff, while a "fix it someday" stash might
only hold abject trash.

And hour fourteen of a three hour auction can yield
exceptional bargains
if the auctioneer gets further behind.
Especially if it is 120 degrees in the shade and no shade
except for the four inch hail. And the rabid bats are not

A "bankruptcy" or "forced sale" might have bunches
of nice stuff in the stash, while an "excess inventory to
ongoing options" routine sale likely only has worthless
and obsolete and broken useless leftovers.

The nature of the business also tells you a lot. Electronic
components from a failed porno coin-op loop shop are less likely
to be mil spec quality than from a belly up aerospace custom supplier.

Your risk goes sharply up if you are unable to physically

Two tips: Rates can be much cheaper if you pick the item

Even tasks as simple as shrink wrapping a skid. But, for

Just picked up a bunch of the "nails" used in
bed-of-nails ATE testing
. These can be ideal for
your own custom test lashups and should shortly
be up on eBay.

The correct name for these are "music wire
translation pins"
. And they elegantly solve the
problem of getting from "standard" spacing on a tester
to "custom" pad patterns on the device being

Here is how they work: The pins are typically 3 to
4 inches long and have a crimp near one end.
A top plate matches your tester. A mid plate has
holes just big enough to catch the crimp and keep
the pins from falling out. A bottom plate matches
the pattern you are trying to measure.

The pins can typically be offset by as much as
0.4 inches
, letting you easily match the exact
test pattern you need without going to a totally
custom test setup.

We have these available in small quantity lots
in several sizes so they are ideal for your custom
test setups. Especially for jobs that could not
justify a full blown ATE tester.

As we've seen a number of times in the past, it is
now often trivial to throw another million calculations
at a problem.
Which is how much of our Magic Sinewave
results came about. Per this tutorial.

Our puzzle of a few weeks ago had only 362,880 possible
solutions. PostScript can easily run theough these in
only a few seconds at most.

One off the more general issues that came up when
brute force solving this code was "How do you generate
all possible combinations of nine unique digits 1-9?"

Simply picking a random 9 digit number would have an
excessive number of false hits. And random shuffling
( Monte Carlo style ) would only give you a 63%
probability of success on the first 362,880 tries.

Here's a cute and fast approach to generate "all but only"
of the combinations...

Auctions that combine a bulk buy option with lot
sales are almost always a sucker bet. I've yet to see
any auction where the bulk sale was not a prewired
giveaway to a selected insider.

This gets even worse when the winning bulk bidder is
allowed to place a higher proxy. Ferinstance, at a
picture framing auction, the chosen bidder might
bid and win at 30K, but proxy bid up to 45K. If there
were 300 lots, the average lot price would have to
exceed $100 without the proxy and $150 with.

Which clearly is in the "ain't gonna happen" range.

Yeah, there can be exceptions. But these are often
few and far between. If what is being sold is remotely
near being a viable business, and if any owner or
employee is not in jail or drug rehab, chances are
that bulk will win.

And that you are wasting your time attending.

Exceptions might be when there are an enormous number
of poisioned lots, only one or two very pricey items that
are not obsolete, or some outrageous obligation ( such
as an epa gas tank dig up ) attached to a bulk sale.

Another advantage of in-panel synchronous inverters
is that currents can easily be optimized by paralleling

Ferinstance, a one square meter panel could consist of
one hundred cell modules, connected as five groups of 20.
Each group might output 12 volts at 3.3 amps peak, and
five phase inverter arm would only have to deal with this
fairly modest current.

Depending on the cell technology used, the ratio of inverter
phases to cells could easily be optimized for the best efficiency
that is combined with the most reasonable per-phase cell
switching currents. Among other advantages, heatsinking
would be dramatically simplified.

By integrating cells with inverters on a per panel basis,
total system performance can easily be optimized.

For many end users, the cost of a synchronous inverter
added to a home pv system can consume 150% of the
value of ALL the electricity sent through it.
Thus guaranteeing
you a gasoline destroying net energy sink, even with
completely free pv panels.

One emerging solution is to distribute the problem,
putting synchronous inverters on each and evey panel.

The electronics this way are far cheaper and simpler.
Once economics of scale and learning curves set in,
there's no reason the total inverter cost should exceed
$9 each,
nor any reason they should be larger than a
two inch cube.

There are many advantates to "plug and go" panels
that directly output 110 vac. The lower currents
make the electronics and its heat control vastly
simpler. "Sweet Spot" Thevenin optimization

One working definition of "engineering" that I prefer
is "A sense of the fitness of things".

One REALLY BAD IDEA that needs immediately
stomped upon is supersizing solar power towers.

This is an engineering rathole of the first order
that is CERTAIN to far exceed costs and CERTAIN to
NEVER deliver net energy.

Conventional solar power towers are marginally useful
and clearly about to be blown out of the water by
stunning new pv developments. pv with advantages of
negligible water needs, incremental expandability,
compatibility with other land uses, minimum approval
hassles, little labor, upcoming true net energy at
competitive rates, low termperatures, future
dramatic learning curve cost reductions, simple
structures, few moving parts that are both low tech and
nonprecise, minimal land disruptions, etc... etc...

The supersize towers would demand a federal land grab
of mind numbing acerage for exclusive use. They will need
water resources far above and beyond what is sanely available.
They demand new strucutres MANY HUNDREDS of feet higher
than any existing Arizona building
! I feel that convection
currents could easily create perpetual hurricane force winds and
conceviably disrupt both regional and global climate. Not
to mention military, bird, and general avaition hassles.

Alarmingly, the feds have been placed on "fast track
approval" for such stupidities.

It seems to me what happened is that a megacorporation spent
way too much money developing an unneeded and useless heat
transfer technology and is desparately trying to trump up uses for

It turns out there are two "flavors" of BNC connectors,
rated for 50 Ohms and 75 Ohms. The 50 Ohm versions
have pins nearly a millimeter in diameter and are intended
for microwave and rf use. The more common 75 Ohm versions
have significantly smaller pins and are intended for video
and cable

For most people most of the time, using the "wrong" style
will not make much difference. Most modern BNC connectors
can safely be interchanged for all but the most critical
of highest frequency performance.

But cerrtain older 50 Ohm male plugs can distort some 75 Ohm
jacks to the point where their reliability could drop.

The rule is to try to keep 50 Ohm connectors in 50 Ohm

How bad is the error if you use the "wrong" shuffling

For equiprobable odds, this ratio has to be an

At n=3, we have 9/2 or 4-1/2. 50% of the
results will have a 20% higher probability

than they should. And clearly is uselessly bad.

At n=4, we have 64/6 or 10-2/3 20% of the
results will have a 10% higher probability
than they should.

At n=5, we have 625/24 or 26-1/24 4% of the
results will have a 3.8% higher probability

than they should.

higher n. And is essentially zero for n=52.

I've long been overly enameled of shuffling algorithms.
Some detailed coverage appeared in my Apple
Assembly Cookbook

It turns out there are two different types of shuffling,
shuffling with replacement (such as dice) or shuffling
without replacement
( such as a deck of cards ).

Shuffling without replacement simply consists of
picking a random number. For dice, a 6 random using
my gonzo utilities works fine, per this tutorial.

Shuffling without replacement can have a sneaky
flaw that biases your results. The obvious ploy of
"interchange all cards with itself or another selected
at random"
creates subtle errors.

Here's why: There are only SIX different outcomes
when shuffling three cards, ABC ACB, BAC, BCA,
CAB, and CBA. But there are TWENTY SEVEN ways
to interchange all with everybody at random. 27 does
not divide into piles of six each very well; thus there will
be unavoidable bias.

Admittedly the bias becomes negligible when you get
up to 52 cards, but it is still definitely there. Instead,
the correct algorithm is "interchange all cards with itself
or another card LOWER IN THE DECK selected at

Again, this is easily done with the gonzo utilities.
Details vary with exactly what you have in mind.

A friend at dinner asked if, even without them being
in any manner renewable or sustainable or green, if
today's conventional silicon solar pv panels did not
in fact have a low carbon footprint.

The surprising answer is that, no, they do not.

First, the concept of "carbon free" is totally bogus.
"Carbon neutral" makes much more engineering,
ecological, and economic sense. Particulaly since
carbon appears to be an essential ingredient in
energy dense liquid fuels. And since its release
contributes significant energy.

Second, the amount of energy delivered by a
conventional pv panel is so laughingly miniscule

that the carbon produced by a conventional
power plant for the same energy is negligible.

But the third and key reason is that today's
panels remain net energy sinks
. Most of their amortization
pretty much represent the average carbon
penalty of the rest of society.

Not to mention the carbon emissions during
manufacturer or those of the delivery truck.

Much more in this tutorial.

Arggh! Found yet another insidious bug in Dreamweaver.

Validation of modern web code demands that you replace
every "&" in a URL with a "&amp;". eBay, search services,
and government websits are particularly adept at using
as many as a dozen ampersands that will need modified.

You can easily do a search and replace in Dreamweaver.
The only tiny problem is that the program will change them
all back to the way they were after an hour or two of
further work!!!

The solution appears to be to replace the ampersands
in an ordinary text editor. Dreamweaver will apparently leave
these the way they were.

One underappreciated engineering concept is the threshold

Three thresholds obviously in the process of being crossed

point sources, flat planel displays now having blown CRT's
completely out of the water, and solid state flash memory
replacing moving media for dramatic improvements in power,
reliability, speed, and size. Plus, soon, cost.

Totally pointless puzzles can end up ridiculously obsessive.
They also can drive home how much you can do with seemingly
unrelated web resources.
From thousands of miles away.

Six decades ago there was a distinctive radio tower that defined
a certain city skyline in the 1950's. At the time, it had a rather
specialized format. I noticed it was still around and wondered
just what it was up to recently.

Starting with Google Maps and Google street view, the tower
was quickly located. Strangely, the address was ambiguious.
Curiously, the building was totally unmarked. Possibly because
of terrorism considerations, and possibly because most radio
stations sell so often that changing the signs gets expensive.
The dual coax feeds on the tower stuggested it was still
commercial FM and now served two frequencies.

An adjacent property was next located on a county tax
roll site similar to this one. From which an older owner
of the site was found. This owner was a radio megaconglomerate
who sold to someone else for $10. This was not a half bad price
for the property, which had a rather decent view.

Some tower info was found from a FCC site similar to this
. Next, a list of local stations of the required distance
from city center was found from a radio resource site
comparable to this one. Their GPS coordinates rapidly
confirmed two active commercial FM stations using the tower.

Both of which were owned by yet another radio megacomglomerate
from a different city. They apparently are using the extra space
in the building to provide web media services to other broadcasters.

Got several emails pointing out that subsidies encourage
sales of pv panels.

Panels that are in no way green, renewable, nor sustainable.
And are gasoline destroying net energy sinks. Using
conventional silicon technology, they always were and always
will be.

Which is precisely the point: There should be a $1000 per
kilowatt TAX on every installed conventional pv panel that is
incapable of net energy.
Rewarding the losers both penalizes
and delays innovation.

Net energy breakeven can be anticipated eight years
after the fully burdened panel costs drop under twenty
five cents per peak watt. Subsidies of loser technology
can only further set back net energy breakeven.

One of the many enigmatic mysteries of the 1898
Safford to Morenci toll road is "Why is there a

The original road construction consisted of removing
rocks and piling them on the ( usually southern ) edge
of the ten foot wide pathway. These rocks were then
loose and formed a continuous bunker some three feet
or so wide and two feet or less high.

Ranchers like to bury their stock tank PVC to keep
the water cooler, minimize damage, and prevent
ultraviolet lifetime trashing. Digging a "real" trench
through extremely rocky soil is both expensive
and time consuming. Not to mention painful.

So, my guess is that they simply laid the

I've combined two earlier files here to make them
more linkable and accessible....

I am mystified why the State of California would blow eight
billion dollars
(plus admin and transfer costs that likely
triple this figure) paying people to put gasoline destroying
net energy sinks
on inappropriate rooftops.

By how many DECADES will the California 8 billion
dollar rathole fiasco SET BACK the development of
renewable and sustainable pv solar electricity?

Clearly, conventional silicon PV panels will never reach
sustainability and renewability. And every cent poured into
this particular rathole can only set back the time when
true renewability/sustainability can emerge.

Let's instead postulate a "pioneer panel", the very first
real world sustainable and renewable pv solar energy
system. What would its characteristics have to be to
allow pv solar energy to be anything but a monumental
"feel good" energy sink and net destroyer of gasoline?

A nominal pioneer panel size would be one square meter
delivering internally synchronously inverted "plug and go"
110 volt 60 Hertz consumer ac power with utility buyback
and storage option.

The at-the-terminals efficiency would have to be in the
forty percent range, brought about by an absolute minimal
material use and ultra low cost processing that involves
spread or multiple workfunctions probably combined with
MEMS nanotechnology techniques using nanoantennas.
Plus possible photonic lattice techniques.

CIGS may also help.

Let's see. Such a panel would generate something like 400
peak watts at appropriate sites, or about 2.5 kilowatt hours
per day. Naturally, only a tiny fraction of the delivered energy
could be renewable and sustainable
, owing to materials cost
and amortization. Let's assume the fully burdened panel can
deliver ten cent per kilowatt hour energy at an infrastructure
cost of eight cents per kilowatt hour for two cents per KWH
of genuine net honest renewable and sustainable energy.

The "old energy" breakeven pay for itself would then be
about twenty cents per day. Assuming a ten year lifetime and
a ten percent interest rate, the retail cost of the zero-installation
hassle panel at Home Depot would have to be under $454.00
total. Or more like $378 in an area with 300 days of available
sunshine. Per this amortization calculator.

I very strongly feel that such a pioneer panel is definitely
acheivable within a one decade time frame. Provided that all
of the ludicrous sideshows are immediately flushed

Naturally, if you build these pioneer panels, they WILL sell.
"Beating your customers away with a stick" comes to mind.
And absolutely ZERO in ludicrously counterproductive and
pointlessly "not even wrong" subsidies would be needed.

The key point is that NOTHING ELSE MATTERS long term
but acheiving pv renewability and sustainability. Clearly, dollars
blown on anything but this specific goal simply set back the
time when solar electricity ever becomes viable.

More in our Energy Fundamentals tutorial.

So let's do some numbers...

Let's assume the 8 bil only costs 8 bil, rather than its
true triple cost after transfers and admin. And that
there are ten million of our pioneer panels per the
above in fact installed and working.

Our projected panel returns two cents of genuinely
renewable and sustatinable pv solar electricity per
kilowatt hour for eight cents of "old energy" gasoline-
in-disguise invested. A 400 watt panel would generate
about 2.5 kilowatt hours per day, or around five cents
of renewable and sustainable net pv solar electricity.

At 300 effective days per year, each panel year would
generate $15 worth of renewable and sustainable
electricity per year. Ten million panels would thus
generate 150 million worth of renewable and sustainable
electricity per year.

8 billion divided by 150 million leaves 53.3 and change.
Thus, the California pv fiasco will likely set back the
development of renewable and sustainable net pv electricity
by a grand total of 5.3 DECADES!

Assuming a zero interest rate, of course.

whites within the image itself. Using this or a similar

optional artsy-craftsy vingnetting.

And this bmp file can instead give you any of a
number of stock backgrounds. These subtle
patterns have been optimized to minimize any
.JPG artifacts.

Should you go with Elmer instead, you scan with the
color sheet near the item. You then pick a very small
color area and expand it into a pleasant and artifact
free background. And then repeatedly cut and paste
to create your knocked out background.

I feel it is nearly always super important to distortion
correct your images to one pixel accuracy, converting to
architect's perspective. This program can be of help.

And this program can let you improve bitmap

drop in its efficiency. Thus, in winter time, your building heating
costs may go up more than you will save in your hot water system

What is really sad is that the place where heat pumps are truly
and genuinely needed -- for hot tubs --, the prices remain
outrageously and uselessly expensive. To the point where they
are not remotely cost effective

The recently improved Gila Valley Satellite
has revealed bunches of new stuff.
But remains frustratingly ambiguious when
it comes to prehistoric artifacts and such.

There appear to be a dozen or so what we
might call thumper loops. These are circular
"roads to nowhere" that are always on a flat
mesa, always close on themselves, and
always remain within a few feet of a steep
mesa edge.

Some hint at internal evidence of CCC
water projects or prehistoric ag structures.

My best guess is that they are "post GPS" roads
for geophysics access, such as seismic exploration
or core drilling.

As a general rule, any topo map feature named
"cave" or anything remotely suggestive has long
ago been checked by Southwestern cavers.

Cavers use binary geology: There are two kinds
of rock, limestone and shit. Except for some
minor lava and gypsum examples, juat about
all decent caves demand limestone. Not just
limestone, but a karst topography where water
can create sinkholes and such.

One intriguing area I have yet to explore is the
"Pothole Country" six miles north of Mule
. There's also a "Cave Canyon" and
a "Pothole Canyon" in the immediate area.

"Pothole" can have several meanings. No
telling exactly what they had in mind.

The geology is almost certainly a useless
volcanic mudstone, and the area seems little
known to cavers. While on Gila National

met with distinctly unfriendly local ranchers.

Found the original documents for the McEniry Tunnel!

This was a scam ( then called a swindle ) to tunnel
clear thru Mount Graham for a total distance of
twelve miles,
revealing untold riches in gold and
silver, besides $300,000 worth of timber and 45,000
horsepower worth of hydro. The leftover water
would irrigate at least 25,000 acres by using 30
miles of canals.

The total known mineralization of Mount Graham,
of course, is approximately zero.
There are only
the tiniest mineral explorations of no consequence
at the extreme range ends. The rock is all intrusive
precambrian gniess or granite. Neither PD nor FM
has expressed the slightest interest in this range.

Getting info on this "somewhat optimistic" proposal
has been tricky. First because it originally was
called the Triumph Tunnel, and later referred
by locals as the Mammoth Graham tunnel.

Over the years, a number of misspellings of
"McEniry" confused the issue. The spelling
here comes from his signature on the above
document. Many credible sources ( including
Arizona Place Names ) have gotten it wrong.

The tunnel was only driven a few hundred feet
and remains of interest today. It is just a plain
old empty horizontal mineshaft. Easily visited.

For several reasons, opportunities in US Military

First and foremost, many surplus sites now ship their items

Turns out the "stripeyness" in our bicubic interpolation
was an imaging issue. The math all checked out,
the curves were all smooth, and inverse math returned
to the original data. Meanwhile, an independent Wiki
entry came up with exactly the same math we used.

Here's a bicubic interpolation summary:

Bicubic interpolation is an obtuse and calculation intense
method of finding intermediate pixel data values. Such
values might be needed for image resizing, rectification,
rotation, or distortion correction.

It starts with sixteen data inputs: the value at each corner,
the x slope at each corner, the y slope at each corner,
and the diagonal xy slope at each corner. It then creates
an "inside" surface that matches these data inputs.

The rather ugly math of the match is...

p(x,y) = a00*x^0^y^0 + a01*x^0^y^1 +
              a02*x^0^y^2 + a03*x^0^y^3 +

             a10*x^1^y^0 + a11*x^1^y^1 +
             a12*x^1^y^2 + a13*x^1^y^3 +

              a20*x^2^y^0 + a21*x^2^y^1 +
              a22*x^3^y^2 + a23*x^2^y^3 +
              a30*x^3^y^0 + a31*x^3^y^1 +
              a32*x^3^y^2 + a33*x^3^y^3

Here axx is a magic coefficient, while x and
y range from 0 to 1 over the inside surface.

The a values are related to the input data...

w0 = f(0,0) = a00
w1 = f(1,0) = a00 + a10 + a20 + a30
w2 = f(0,1) = a00 + a01 + a02 + a03
w3 = f(1,1) = a00 + a10 + a20 + a30 +
                      a01 + a11 + a21 + a31 +
                      a02 + a12 + a22 + a32 +
                      a03 + a13 + a23 + a33

x0 = fx(0,0) = a10
x1 = fx(1,0) = a10 + 2a20 + 3a30
x2 = fx(0,1) = a10 + a11 + a12 + a13
x3 = fx(1,1) = 1*(a10 + a11 + a12 + a13) +
                       2*(a20 + a21 + a22 + a23) +
                       3*(a30 + a31 + a32 + a33)

y0 = fy(0,0) = a01
y1 = fy(1,0) = a01 + a11 + a21 + a31
y2 = fy(0,1) = a01 +2Aa02 + 3a03
y3 = fy(1,1) = 1*(a01+a11+a21+a31) +
                       2*(a02+a12+a22+a32) +

z0 = fxy(0,0) = a11
z1 = fxy(1,0) = a11 + 2a21 + 3a31
z2 = fxy(0,1) = a11 + 2a12 + 3a13
z3 = fxy(1,1) = 1*a11 + 2*a12 + 3*a13 +
                         2*a21 + 4*a22 + 6*a23 +
                         3*a31 + 6*a32 + 9*a33

Here wx is a corner value, xx is a corner
x slope, yx is a corner y slope, and zx is
a corner xy diagonal slope.

Solving the above equation for axx values

a00 = w0, a01 = y0a02 = -3w0 + 3w2 -2y0 - y2
a03 = 2w0 - 2w2 + y0 + y2

a10 = x0
a11 = z0
a12 = -3x0 + 3x2 - 2z0 - z2
a13 = 2x0 - 2x2 + z0 + z2

a20 = -3w0 + 3w1 - 2x0 - x1
a21 = -3y0 + 3y1 - 2z0 - z1
a22 = 9w0 - 9w1 - 9w2 + 9w3 + 6x0 + 3x1 +
         -6x2 - 3x3 + 6y0 - 6y1 + 3y2 - 3y3 +
          4z0 + 2z1 + 2z2 + z3
a23 = -6w0 + 6w1 + 6w2 - 6w3 -4x0 - 2x1 +
           4x2 + 2x3 -3y0 + 3y1 - 3y2 + 3y3 +
          -2z0 - z1 - 2z2 - z3

a30 = 2w0 - 2w1 + x0 + x1
a31 = 2y0 - 2y1 + z0 + z1
a32 = -6w0 + 6w1 + 6w2 -6 w3 -3x0 - 3x1 +

It is no secret that utilities are madly scrambling towards
automated remote meter readings. First to reduce costs,
secondly to eliminate estimating errors, and thirdly to
be able to eventually do selective load shedding.

Meanwhile, users have a crying need for real time monitoring
of their electric and other usage. Rather than having two
separate systems, to me it makes the most sense to build
web friendly remote reading directly into the meter that
EITHER the utility or the user can monitor at their comvenience.

Chances are that some sort of WiFi scheme, with or without
repeaters or concentrators would prove the most reasonable

My own approach to this was something I never quite

A U-Haul truck rental can be an incredibly good deal.
Provided you only use it locally for less than a day.
Rates start at $19. Which can be much less than
renting a car instead!

But there are some gotchas. There is a mileage charge
of 59 cents a mile. Which racks up alarmingly on longer
distances. And U-Haul is a master at nickel and diming
over insurance, mats, and other add-ons. Their $169
trailer hitch can easily cost you $400+ out the door.

But their real secret is their one way charge adjustments.
It costs a lot more to go one way from a location with
scarce equipment to one with lots of equipment than
vice versa. This varies from day to day and time of
week as well.

Ferinstance, San Diego to Thatcher might cost you
$442 plus fuel, while Thatcher to San Diego might
be $724 plus fuel!

In general, the one way and round trip rates will often
end up around the same
if both locations have
a "normal"inventory. Total time and "second
driver" considerations may shade points one way
or the other for you.

Two of their lesser known ( and somewhat rarer )
offerings are their 5x8 or 6x12 open trailers.

and unload and may travel easier.

easier than two wheel ones

might be less of an overall hassle. Also, their
trailers do not unhitch worth a damn for

I never could justify owning my own trailer.

service alone is worth any cost difference.

A repetitive asymetric waveform will consist of

this equivalence. There are no "gaps" in the waveform!

Meanwhile, Faraday's Law GUARANTEES that only
the dc offset contributes to electrolysis
. All the sinewaves
and harmonics can do is create cell heat and trash the

conventional electrolysis as "continuous DC".

Summarizing the key points: Electrolysis is the process

A fundamental thermodynamic principle of exergy

Faraday's Law
ain't broke. Continuous direct current
is GUARANTEED to be more efficient than any
possible pulse scheme. All the pulse schemes do is
make "not even wrong" deceptive measurments
ridiculously easier to do.

Electrolysis is a current driven process. ALL older
current sources are inherently inefficient by definition.

Only when exotic switchmode techniques are used can
reasonably efficiencies ( at destroying value ) be created.

Stainless steel is utterly useless for efficient electrolysis
because of the hydrogen overvoltage of iron found in
any intro electrochem book. If you must do serious
electrolysis, platinized platinum electrodes are a must.

An ordinary car alternator is only around 45 percent
efficient and the maximum available excess power that
can be sent through an ordinary fanbelt is a few hundred
watts at most. Thus, the primary product of onboard
vehicle electrolysis is trivial quantities of useless low grade
heat. And is exactly the same as running with your
emergency brake partially on.

The bottom line is this: If you do not understand exergy,
you SHOULD NOT be pissing around with electrolysis.

If you do understand exergy, you WILL NOT be pissing
around with electrolysis.

Either way, the outcome is not the least in doubt.

Slopes were taken as half the difference between the previous
and the post value. Which works reasonably well for many
possible data values.

But consider the case of previous=0, current=0, and post=1.
The true current slope should be zero with a sudden transition
halfway to post. An average gives you 0.5.

Finding a fast way of determining the derivative at the
current point may be tricky.
A five point fit to a quartic
function would probably take forever. Something wierd
and simple might be an interesting compromise.

Please email me with your solution.

Apparently Arizona Highways magazine failed to
make even the most cursory fact finding check on
their latest issue. In which they recommend a
dangerous and highly sensitive cave as being ideal
for casual family trips with small children.

And not even checking the contact info in the story
Yes, magazines in general are in deep shit,
but this is clearly excessive and unacceptable.

The cave in question is arguably the second or third
"finest" in the state
. Exploration is quite difficult,
rather strenuous, and demands advance rope
techniques and extreme physically fitness and
endurance for virtually all participants.

There has been one fatality
involving a fall down a
90 foot pit. Plus numerous high tech rescues of supposedly
experienced and highly skilled long term members of
the cave community.

Worse, the story implied that there was a commercial
adventure-for-hire service that routinely would take
anyone on this cave tour. In reality, this group is an all
volunteer organization whose foremost goal is preserving
the cave and tightly restricting its access.
Even public
knowledge of the cave or its location is strongly discouraged.

Well, maybe a hint. At least some of the better known portions
of the cave are located south of the Mackenzie River.

Made two more trips to the cliffhanging canal. And
the engineering remains orders of magnitude beyond

What we have here is a thirteenth century canal system
literally hung on the TOP edge of a steep mesa. Often as
much as NINETY FEET above the valley floor. As part
of a system that is at least 12.5 kilometers (or eight
miles) long. Not to mention several hundred feet of
above grade aquaduct!

Major portions of the system are still amazingly well
preserved and undisturbed.

Besides the obvious question of "WHY?", many
questions remain. Was water hand carried to the mesa
top? What happens at the East End of the mesa where
the terrain simply quits? After miles of carefully controlled
slope, are steep drops inevitable? What leveling instruments
were used for such precision? Why is much of the canal
brim full of fine sand?

Watch out for the cliff. "What Clliiiiffffffffffffff.... ?"

eBay may be in the process of "improvements"
that drastically limit the maximum image sizes they will
host for you in a normal listing.
Which can severely
impact the usefulness for such things as test equipment
front panel details.

At present, there seems to be a mix of "old" and "new"
offer formats, seeingly presented at random. Getting
solutions that work for both schemes can be tricky.

If you are only interested in inserting your own larger
picture into your offer, this code works...

    < img src="http://www.site.com/image.jpg">

If instead, you want to provide one picture that you
can click on for a second picture, use this...

    < a href="http://www.site.com/bigimage.jpg">
    < img src="http://www.site.com/smallimage.jpg">


You can also use the above code to link different
file types, perhaps to access a data sheet or whatever.

The "big picture" link should also show up in your
log files. Which gives you another route to
response tracking.

Their "small pictures only" restriction is so bad
that I expect enough complaints will rescind
it. If permananent, all of your listings that are
image size critical will have to be changed

Here's a summary of the more common stupid beginner's
mistakes that many eBay newbie sellers make...

     on one of these has at least one problem. Most
     of it has been higraded. Much is unsuitable for
     eBay sales. Shipping charges can be outrageous
     and your opportunities for personal value added
     are often severely limited.

     something near a 30:1 sell/buy ratio. Even with a  50%
     commission, you only have a ludicrous 2:1 SBR. Worse,
     price expectaions of outsiders is usually outrageously
     out of line. Besides "them" not understanding the
     nature and obligations of UCC contract law.

     FOREIGN SALES - If you are a success with domestic
     sales, foreign sales are not needed. If you fail domestically,
     foreign sales will not help you in the least. There are
     far too many ripoff opportunities, misunderstandings,
    bureaucratic keytowing, outright lies, and third party costs
    to make foreign sales even remotely worthwhile.

     DROP SHIPPING- Problems with dropshipping ( more
     correctlyl called "dropshitting" ) are (1) There are
     waaaaay too many fingers in the pie.  (2) Far too many
     competitors WILL panic and WILL trash prices.
     (3) The sell/buy ratio is ludicrously too low.  (4) Any
     opportunities for personal value added are sorely limited.
     (5) The majority of products offered are outrageously
     overpriced unsellably useless trash. And, of course..
     (6) It is YOU that gets hung out to dry on the inevitable
    noship, lateship, or wrongship.

    GOUGING ON SHIPPING- Your shipping charges should
    always be revenue neutral and the most reasonable method
     for your buyer. Tracking should always be provided. Your
     best route for insurance is an unannounced self-insure.
    Protected, of course, by your 30:1 SBR.

    SHILLING- Bidding up your own prices simply does not
    work on eBay. First because shillers will be making enough
    other stupid mistakes that they guarantee failure. Second,
    because the two key elements of shilling ( mark demeanor
    feedback and auctioneer bailout ) are totally absent in the
    eBay venue, and thirdly, because any intelligent buyer will
    bid only once very late in the auction. Thus thwarting any and
    all shilling attempts.

Sometimes the smallest bugs can be maddingly infuriating.
And digging them out can become obsessive. The bicubic
map on our Pixel Interpolation GuruGram seems to have
some minor "stripedness" in the orange that clearly
should not be there.

It is not clear whether this is a coefficient error, an algorithm
error, a rendering error, a truncation error, or inherent
limits in PostScript's 32 bit math.
It does seem more
"vertical" related and "rightside" related.

The usual approaches of simplify, then make the problem
should be a useful avenue of attack. And then making
actual numeric printouts to verify that the stripes are real
and which coefficients are the cause.

A tactic approaching dollar cost averaging can
increase your yield at a distress auction. It goes
something like this...

Chances are you will win a few lots for much less
than you intended paying for them
. Your "savings"
can be applied to somewhat overpay for other lots
and you still will be within your cost goals.

But only when and as accumulated.

Naturally, you should apply this ploy only to items
that you find genuinely of value. And always
strictly stay within your average maximum bid

Several other cavers have been wondering if it
is possible to make microtemperature measurements.
Accurate enough to track airflow through unexplored
breakdown leads.

Doing so would probably involve measurement to
. And almost certainly, the presence of
people or instruments would trash the results. Not
to mention hunidity and other side effects.

I was recently playing with a Keithley 196 precision
standards DMM that had beyond a 6-1/2 digit
capability. It had a RTD temperature accessory that
clearly allowed measurements to one tenth of a millidegree.

The system easily detects a human hand at a range of
two or more feet. It is fascinating to watch a room's
temperature change on a second by second basis. And
should have all sorts of heat flow and insulation
experimental properties.

Sadly, it is probably too klutzy for serious cave use.
And probably misses by several orders of magnitude
for what would be needed in a cave instrument.

Just saw a PR release for a pv panel that was supposedly
generating 1200 watts from 20 square feet. Is this a
stunning breakthrough, wishful thinking, or totally
bogus bullshit?

10 square feet is 0.929 square meters. The normal
best incoming solar energy would be around 1000 watts per
square meter. If ordinary silicon solar panels were in use,
you would be lucky to get 180 watts at the battery terminals.

That is assuming you have a super efficient and complex
"sweet spot" optimizing battery charger, that the cells
are 100 percent active, and that the panel is optimally
tracking under noon Arizona conditions.

A more reasonable estimate would be 120 watts peak
under best possible conditions for the system described
if used in the real world .

Mysterious artifacts abound in the desert southwest
and especially here in the Gila Valley.

One of the more obviously intriguing examples are
the "hotdog formations" 5 miles SxSSE of Swift
Trail Junction. AKA SW quarter of section 9 or
somewhere near N 32 39' 45" W 109 41' 39"

These are three foot high dirt "bunkers"
with rock
buttressing that are several dozens of feet long.
Also nearby are ( apparently useless ) rock check
dams piled much higher than usual. Use is, to say the
least, nonobvious.

They do not seem prehistoric in that there is no
association with potsherds, lithics, fields, or habitation sites.
The rocks also seem to have been moved a significant
distance, most likely by wheeled transport. They also
look "too new".

The nearest 4WD track is 900 feet south and the
property is BLM Rangeland. Expanations of rifle
range backdrops, scouting projects, erosion control,
cattleguards, hoaxes, movies or vid commercials, kids
pissing around, drug dealers, UFO landing sites, or
rancher improvements all seem unlikely. There are
no obvious trash artifacts, modern or otherwise.

I am at a loss to explain these. The simplest thing
is to blame them on the CCC
. Who have proven
adept at doing totally useless stuff in strange ways.

Nearest CCC camp was 8 miles away at Noon Creek.
The artifacts do not show on available images.

A tiny bit of supporting evidence is that some of
the rock arrangements show "Italian stone masonry"
careful arrangement and placement
quite similar to
those of other known CCC sites. No concrete is used.
The motif is distinctly unsouthwest.

Your comments welcome.

A wind turbine efficiency claim of 85% is obviously
bogus bullshit and can be dismissed out of hand.

Turns out there is a fundamental law of windmills
and wind turbines called Betz' Law. Which says that
you ain't gonna get 60% under perfect conditions.

The absolute limit is apparently 59.3 percent.

The law is also fairly intuitively obvious. A 100%

Boy, a whole flock of 'em flew over that time.

Check out the reader comments on the above
link. It is utterly amazing what happens when obvious
scams and wishful thinking overlay real science.

One more time kiddies...

1. There is credible, peer reviewed
    real science that a modest amount
    ( 5% ) of hydrogen injection can
   significantly improve the performance
   of a carefully redesigned ICE internal
   combustion engine. As reviewed below.

2. Thermodynamic fundamentals involving
     exergy positively, emphatically and
     absolutely GUARANTEE that such
     hydrogen ain't gonna come from onboard
     electrolysis by way of an ordinary fanbelt
     and a stock alternator.

It has yet to be shown where the hydrogen
would safely and economically come from for
(1). Obvious candidates are exhaust gas
reformation, catalyitic cracking of the
input gasoline stream, or tanks prefilled at
the hydrogen store. As of this writing, no
solution is known.
Despite many attempts.
And despite many of the papers being as
much as three decades or more old.

A detailed analysis of the ludicrosity of (2)
appears here. Five of the many absurdities
are the assumption that an alternator does
not disproportionately load the engine, that
an oridnary car alternator is more than 45
percent efficient, that stainless steel can in
some manner be used for efficient electrolysis
( the hydrogen overvoltage of iron guarantees
that it can not per any intro electrochem book ),
that more than a few hundred new watts can be
run through an ordinary fanbelt, or that the
usual scam setup is anything but an useless
generator of worthless
low grade heat

The latter category killer is similar to keeping
your emergency brake partially set at all times!

At any rate, here are a few of the "real
science" papers involved....

of the generated notes, and background noise problems
caused by "always there" but unvoiced notes.

Since then, there have been major developments in
electronic music. First and foremost is the MIDI
standard. The second is FM Synthesis pioneered
by Chowning. The third is the use of personal computer
sound cards. The fourth is the use of sampled data

Useful resources include Ensoniq ( now E-MU ) , and
Yamaha. Their YM3812 was a definitive FM synthesis
product, while the Ensoniq Xboard 61 is a good example
of a modern MIDI synth instrument.

eBay is apparently dropping their Dutch Auction format.

There were several problems. First, a "true" Dutch
Auction is nothing like what eBay was offering. In which
the price starts high and drops till sold. This takes a
very alert live auctioneer to maximize returns and
prevent fistfights.

Second, the eBay charges were based on the assumption
that all items would sell on first listing.
Leading to
utterly outrageous fees for higher quantity offers.

Third was the Dutch Auction Trap. In which a buyer
ended up paying his FULL PROXY PRICE
if they
bought all n items. Rather than n-1 or fewer.

The handiest way I have found to email a location of most
anything to anybody is to use Acme Mapper.

Usually, you will select satellite and an appropriate scale.
Center the item on the crosshair and click mark. Then link
to this page.

Since the email link may end up over one line long, be sure
to prefix and postfix any link with "<" and ">".

Three areial resolutions are typical: Really bad ( such as
aound Fort Thomas AZ ), about a meter ( such as around
Safford, AZ ), or better than half a meter ( such as downtown
Phoenix ). Sadly, prehistoric structures are hard to spot
even with the finest resolution offered today.

The highest resolution is sometimes available using
Acme's DOQ feature. But this is black and white and
at best only marginally better.

Decimeter resolution everywhere sure would be nice.
In stereo with uv and ir options, of course.

We looked at the Fundamental Factors Underlying
Technological Innovation
a while back. And made two
additions here and here. Yet another factor that might be
added is the end of scarcity.

businesses and services were once based on
picking up a pile of arcane equipment or expertise and
being the sole local source for what was being offered.

Innovative new solutions now give most anybody the
ability to knock out better product. Faster, simpler,
and cheaper.
Where competitors were once few and
far between, there are now hundreds of thousands or
even millions of them.

Some examples of stuff already shot out of the saddle...

    PRINT SHOPS - At one time, you had to buy
    a fancy printing press and zillions of support
    items like litho cameras, artwaxers, platemakers,
    joggers, punches, binders, green eyeshades, etc.
    These days, anybody with an inkjet or a laser printer
    can instantly produce what they need when they need it.

   PHOTO FINISHING - Here you had to have an
   enlarger and a darkroom, along with all of the
   "slopping in the slush" accessories. Now, you
   can use Imageview32 or any of hundreds of
   free computer programs to do much more
   image postproc much better. And ridiculously faster.

   TRAVEL AGENCIES - Specialized contacts
   and insider info clearly have been replaced by
   online services newly available to anyone 24/7.

    RESEACH SERVICES - At one time,
    profitable consulting could be based on knowning
    which libraries to use when, agressive subscriptions
    to trade journals and industrial shows and such.
    Because accurate and useful info was scarce.

    Now just about anybody can do an instant Google
    Search to come up with more and better information.

    FONTS - Long ago, adding a new font capability
    to what you were doing was a gut wrenching experience
    Fonts, of course, were one size and one weight at a time.
    Today, thousands of fonts are available free, and hundreds
    of them are included in standard publication software.

    CREATIVE WRITING -Magazines typically had "room"
    for a small stable of regular authors. At least some of
    which quickly established reps as sought out resources.

    The explosive onscene arrival of the blog now means
    that there are hundreds of thousands or even millions of new
    info and entertainment sources
. Like it or not, some of them
    are better than you. At the very least, there are now many
    thousands of highly competitive clones.

    SPECIALTY STORES -It used to be that if you needed,
    say, some candles, that you would go to a brick and mortar
    specialty store. But today there are great heaping bunches
    of candles available 24/7 on eBay, Craig's List, or Kijii.
    The scarcity of sources is clearly gone.

There's bunches of obvious stuff that is about to get unscarce.

Books about to blown out of the water by eBook readers.
Newspapers whose economics are now absurd. Over the air
and cable tv laugingly obsoleted by web delivery. Outrageously
expensive, slow, and hard to obtain peer reviewed scholarly
pubs shot out of the saddle by instant web distribution.

Trade journals, again due to ludicrous economics. And, of course,
music delivered from tens of thousands of sources that are much
more cheaply produced that the cost of one hour of traditional studio

The bottom line is that there are no more reject slips. Nor any valid
reason to limit the selection and availability of most any product.

Scarcity is now gone.

Things may not be quite as bad as they seem. But
easily could get a lot worse if the government continues
to blatantly reward stupidity.

To me, the bailouts make no sense whatsoever in that
they penalize the winners by rewarding the losers.

Locally, restaurants seem even more crowded at
lunchtime. Of, the few folks who lost their jobs that I
know of, several were glad it happened, and others
quickly found alternate work. And the bustle seems
back at the UPS terminal. Crime is actually down a
tad because many of the bad guys left town.

Both oil and copper seem to have stabilized at
"normal" and "expected" pricing.

I was anticipating some super opportunities involving
auctions. But they do not seem to be happening. At
least not yet.

At a recent major computer store auction, some 10,000 lots
of somewhat dated items all went for better than
eBay or WalMart prices. Even in huge quantities. And there
seems to be few if any local business failure or liquidation auctions.
If anything, these seem fewer and further between.

The key secret appears to be looking for the more
obscure listings from the more unlikely auction houses.

And to attending fewer auctions but striking fast and
hard whenever genuine opportunities crop up. And
paying extreme attention to detail to the resources
available to you
. While always leading with your
specific expertise and personal value added.

Many auction house listings appear here. Your own
custom regional auction finder can be created for you

Many people have trouble visualizing exactly how big
a Joule is. Leading to all sorts of fundamental misunderstandings
on alternate and regular energy fundamentals. Which is
why I overwhelmingly prefer to use kilowatt hours instead.
regardless of whether we are talking electrical, mechanical,
or some other form of energy.

A Joule is unit of energy ( the capability to do work ) defined
as one watt second. Very roughly, a Joule is somewhat the
same size as a foot pound of mechanical work
. More exactly,
a Joule is 0.736 foot pounds. Which you can look up here,
or get by dividing the 550 foot pounds per second horsepower
definition by the 746 watts in a horsepower.

By simple time scaling, there are 60 Joules in a watt minute,
3600 Joules in a watt hour, and 3,600,000 Joules in a kilowatt
A kilowatt hour of electricity often sells for a dime.

The relationship of a watt second being roughly a foot pound
gives us a second method of estimating the performance of
a water pumped storage system.

For a ten foot head, you get ( before scaling for efficiency )
ten foot pounds of stored energy per pound of water. Or
22.05 foot pounds of stored energy per kilogram of water.

Or an energy density of just over 16 watt seconds per kilogram
of water at a ten foot head. Or 0.00444 watt hours per kilogram.
Which in the case of water is identically 0.00444 watt hours
per liter. By way of comparison, gasoline is 9000 watt hours
per liter.

Much more in our energy fundamentals tutorials here and here.

As we recently saw here, there is NO pv or wind energy
storage problem because synchronous inversion to the
power grid completely and effectively solves the problem for the
overwhelming majority of real world users.

There are some utter fantasies kicking around the newsgroups
over home scale pumped storage.
Even a casual glance at the
numbers shows how utterly ridiculous the concept is.

Yes, properly sited utility scale pumped storage works
amazingly well and can approach 85 percent efficiency. The
profit in the scheme comes about by filling the upper whatever
with two cents per kwh baseline energy and emptying it with
eight cents per kwh avoided cost peaking energy.

We will forget about how "water anything" creates major
and largely unsolvable legal issues,
especially in the southwest.

Instead, let's look at the underlying math. Say you have two
ponds differing in elevation by ten feet and you want to store
10 kilowatts of power delivered at least over a ten hour
storage time. For 100 kwh total.

How much water is involved?

Let's see. A horsepower is 550 foot pounds per second or 746 watts. A
kilowatt is then 550/.746 =  737 foot pounds. Lets assume a 50%
efficiency, which is insanely unlikely for, say roughly 1500 foot pounds
of input water. 150 pounds of water per second will need continuously
moved over a ten foot head. Or almost 20 gallons per second. For 10
kw peak delivery, 200 gallons per second.

200 gallons per second is 12,000 gallons per minute. Or the
equivalent flow rate of TEN typical city fire engines!

12,000 gallons per minute is 720,000 gallons per hour. Or
7,200,000 gallons total storage for ten hours. An acre foot is
about 330,000 gallons, so we are talking almost 22 acre feet
of water. Enough water to irrigate at least three acres of cotton
for an entire year.

Wait. It gets even uglier. If the water level in the ponds is only
going to be allowed to change by less than a foot, then
nearly FIFTY ACRES of pond surfaces will be neecded.

Further, this assumes that the water charge and discharge rates
are the same. Typically, you will want to fill the upper pond
MUCH FASTER than you empty it.
Which compounds the
flow rates and pump sizes.

Ten feet of effective head can be enormously difficult
to find in certain parts of the country. A typical river
has a slope of five feet per mile or less.

There are many rock structures here in the Gila valley.
Some of these are prehistoric indian agricultural work,
and some are CCC busywork projects from the 1930's.

Telling which from what can create problems. Here are
a few guidelines...

      CCC projects tend to be anal. Prehistoric projects tend
      towards zen and in harmony with the land..

      CCC projects are often obvious on satellite photos.
      Prehistoric projects are usually subtle or invisible.

      CCC projects are usually linear. Prehistoric projects are
      often associated with grids, fieldhouses, cairns,
      or roasting pits..

     CCC projects may have obvious modern features
     such as survey markers, railroad rails, concrete,
     wire grids, or integrated wide farm roads.

    Prehistoric projects may have lithics, trincheras, or
    checkdams with aprons associated with them.
    But potsherds are often rare at an ag site.

    CCC projects tend to be wider, with three to
    four feet being typical. Stones are often
    precisely fit "masonry style" with tight
    tolerances and well defined project edges.

    Some CCC projects tend to be crisp and
    pristine. Prehistoric projects tend to show their
    age and are often partial or ill defined. Or
    show flood damage.

   Prehistoric projects usually use nearby rocks. CCC
   projects may truck or otherwise import different
   rock styles from remote areas.

One of the major myths of pv and windpower is that
"storage" is in some manner needed or unsolved.

In reality, synchronous inversion to the power grid
provides an exact equivalent to storage
and does so
ridiculously cheaper, simpler, more reliably, more
safely, and far more convenient than any other known

The actual process is called "displacement", but you
can view a utility's buyback of wind or pv as a super efficient
solar to coal converter.

As more and more pv or wind peaking is returned, the pile of
coal at the baseline plant
does not diminish as fast. In fact,
if improperly rescheduled, the pile of coal will actually get

Yes, synchronous inverters remain expensive today, but
there is no reason for them not to drop from their $2500
end user installed cost to around $9. Brought about
simply by standardization, learning curves, and volume.
The inverter is actually less complicated than a PC power
supply whose volume costs are under $10.

So long as wind or pv peaking remains a relatively small
fraction of the total energy consumption, this storage
equivalent will continue to be a complete solution. Above
about 30% peaking, some system stability issues might
arise. These are unlikely within the next fifty years.

Found the "horses mouth" document on measuring

A somewhat poor scanned reprint appears here.

To me, there is not the slightest doubt that we are

. Sadly, the current crop of eBook readers
misses the mark badly. And it is not at all clear whether
the "killer ap" book replacement will be an eBook reader

But its gonna happen, and happen soon. Already, such
publishers as the New York Times could save zillions of
dollars yearly by buying each of their readers one of the
marginal eBook readers available today. The economics
are not even close.

First and foremost, the legibility has to blow away a book.

to magnify with improving resolution. The quality of
presentation must at a bare minimum match a full page

materia from most of the available sources.

Third, of course, is that the ebook appliance supplier should not
in any manner be involved with the sale or distribution
of existing books.
To do so is an obvious and clearly fatal conflict of

Fourth, if a propriety format is ever used at all, it should be an option.
All popular "open" formats MUST be supported. Especially
and most crucially PDF.

Fifth, the owner of the appliance MUST be able to freely upload

Sixth, the winning appliance will also allow the watching of
HDTV movies

People want things to happen 24/7 aka NOW. Stuff can
now easily be bought and sold online at any time of day.

Digital cameras are an obvious example

The demise of the trade journal is being directly caused
by their obsene ad turnaround times.
You'd create and
submit your ad and it would not appear in print for weeks
or months later. More weeks and months for some
bingo card results to dribble in. More weeks and months
for them to respond to your mailings and ad followups.
And then maybe -- just maybe -- a sale or two.

The new video sites coming online like Gangbusters is
yet another example.
Theee now deliver thousands of
movies and tv episodes whenever you want to start them
with full pause, fast forward, and rewind. And are utterly
and completely blowing away on-the-air and cable tv
services in the process. Besides block busting Blockbuster.

The upcoming ebook readers or similar appliances can
shortly be expected to do the same thing to print and
. A reasonable authors royalty rate is now
90 percent, and publishing turnaround time from submission
to publication should be less than fifteen minutes max.
Acceptance of your material is, of course, a certainty.

CGI and similar techniques have revolutionized moviemaking.
We can shortly expect someone working at home to come
up with an experience comparable to a major motion picture
at a total cost of $67.73 and a total time involvement of
three weeks. Thus leading to a one million to one reduction
in the cost of watchable entertainment.

Recording studio time is now around $800 per hour. But you
can now easily build your own better recording studio for
around $790.
Producing your own music ridiculously faster,
higher quality, and with infinitely fewer ripoffs than before.
And, once again, with acceptance a certainty.

There's always proposed "improvements" to the

The "standard" line cord used these days on just
about all computers and test equipment is called an IEC
or connector.

Older electronics had some other solutions that can
be hard to work with.

Some older gear used hard wired line cords. These could
easily go bad, especially when a heavier unit was set on
end. If you must replace a cord on these, changing to a
socketed IEC connector is often the best choice.

The latest assemblies combine a switch, fuse, connector, and
optional voltage selector.

The most common problem are the three pin connectors
used on earlier Hewlett Packard HP gear. This remains
available as a Belden 17280. Many larger electronic
distributors still stock these.

Volex is apparently the current Belden manufacturer.

It is important to note that there are two identical
styles of 3 pin connectors, namely HP and "everybody
else". Safety issues come up if you use the wrong
connector as the fuse and switch will no longer be on
the hot side. The "wrong" line cord is the 17952.

Older television sets had a two pin safety interlock
that kept you from applying power when the back
was removed. The workaround is called a "cheater
" and these remain available from many sources.

Genral Radio ( GR or GenRad ) used ordinary male
three pronged power plugs that were chassis mounted
to their gear. Sometimes restricted by a circular hole.
Some hardware store extension cords can be used directly.

Often a cheaper and better substitute is the Tripp Lite
P002-002 IEC to NEMA5 adaptor
. You simply plug
this into an ordinary IEC line cord. On some GR
gear, this will fit unmodified. Others may need a
minor and safe amount of insulation carving using
an Xacto knife or a file.

One of my projects I never got around to finishing and

tennis ball shaped object you clamped onto your incoming
ac power wires ahead of the meter.

Inside was a current transformer, a dc energy harvester,
a current transducer, a micropower chip, and a wireless
transmitter. Your computer would then receive and process
your power consumption real time. With a trivial installation
and minimal safety or compliance issues.

Somebody else has apparently come up with half of
the solution. By simply combining an ordinary plugin
wattmeter with a stock wireless module.
Its only
limitation compared to the isopod is that it monitors
only a single appliance or whatever at a time.

Turns out there are fairly simple instruments
available to measue the thickness of the copper on
printed circuit boards. At least accurate enough to
tell the difference between one ounce and two
ounce copper.

Apparently these simply measure the dc sheet
resistivity using a four point Kelvin setup.

One ounce copper has 0.68 milliohms per square
resistivity for 25 micrometer thickness.

Two ounce copper would be one half that.

Curiously, resistivity is measured "per square"
Square what does not matter in the least because
if you double the length you double the resistance
and if you double the width you half the resistance.

The math behind the machine is found here. A four
point measurement is done by applying current to
the outside two terminals and measuring the voltage
across the inside two.

While the general field solution is messy, if you assume
the thickness is very small and that the sheet borders are
at least four times the electrode spacing, the sheet
resistance will be 4.3 times the current to voltage ratio.

And the sheet resistance will be inversely proportional
to the foil thickness.

Many older pieces of test equipment will have
bad NiCad battery packs in them. These can be
outrageously expensive, even if and when they can
be found.

In the years since, the "sub-C" Nicads started
being offered wit solderable tabs. The energy
density of NiCads doubled and going to NiMH
doubled again. Then lithium came in at ten times
the performance.

Often a much smaller and cheaper battery pack
can be kludged up that will fit in the same space
as the original. This can be a cost effective solution.

One recent problem involved a GR 1232A tuned
amplifier and null detector.
This required a tubular
mercury batter pack that is no longer available.
A GR NiCad charger replacement is also virtually
impossible to find.

The power needs are a mere 12 volts at 2.5 ma.
There is lots of space inside the unit for a pair
of plain old Radio Shack AAA quad or a single
octal battery holders.

But an even better solution is to use one inch
lithium coin cells. These are rated as high as
1000 maH and easily fit the existing battery
tube. A spacer ( perhaps made from foam and
two wired contacts ) will have to be added to
shorten the effective length of the battery tube.

Four of these 3 volt cells cost about $5 on the web
and should give hundreds of hours of operation at
five cents an hour.

Your best solution depends on whether you are
restoring the unit as a collectable or actually
using it as a null detecting tuned amplifier.

system. Which I had wrongly been crediting to early farm
pioneers in the 1800's. Turns out it was a small part of a much larger
and more complex native american system dating from the 1300's.

Apparently they simply stole the plans.

I just received a portion of a yet to be published paper and map
of this original system. It is clearly one of the more stunning of
many early Gila Valley water projects.

Firstoff, the origional system was at least 12.5 kilometers
( or nearly eight miles ) long! It was designed with cutoffs
so that any catastrophic flood would completely miss nearly
all of the system except for an easily repaired head end.

Amazingly, there was an aqueduct or "above grade" portion
where the canal crossed a drainage. And a fairly long
"cliff hanger" portion where the canal was literally stuck
high on the side of a steep mesa.

Finally, the far end of the canal ended in a large loop.
Exactly why it does so is a mystery, since any canal
( especially a prehistoric one ) has to have a gradient
to deliver useful amounts of water.

Portions of the canal system remain remarkably well
preserved. I'll try to post a better reference when the
paper becomes available.

Have had several more "expect the unexpected"
when it comes to refurbing older equipment.

Older vacuum tube gear normally has problems
with its electrolytic capacitors or the tubes themselves.
But a plain old and usually reliable power switch

was the cause of a recent GR failure.

A newer power supply was marked "blows circuit
breakers". The usual suspect here should have been
a shorted electrolytic or possibly a bad diode. Again,
the problem was the input 110/220 switch. Poor
assembly soldering got hot too close to case.

A student lab breadboard can reasonably expect
damage from students inputing the wrong voltages in
the wrong place at the wrong time. Yet this item
had two hairline cracks in its printed circuit board
that almost certainly were a manufacturing defect
that finally opened by themselves without any help..

All of the power supplies in a HP function generator had dead
shorts on them. Yet the regulators checked out
perfectly. Turns out the instrument was dropped which
broke the plastic ends on a connector. The connector
shifted just enough to short adjacent contacts.

In one infuriatingly difficult to fix programmable wire
stripper, the polarity completely reversed on one of
the power supplies. Turns out that someone tried to
replace a bridge rectifier and got it in backwards.

An emergency lighting source can expect bad nicads
after years of unused storage. Yet the problem here
was simply a bell clapper that somhow jumped the track.
Had the clapper end been a quarter inch longer, the
problem would never have happened. Clearly this
was a design defect.

An autoclave was shipped across the country and
received nonworking. They sent it to a local repair
shop who pronounced it unrepairable. We refunded
and got it back. Snapping an obviously shaken switch
back together immediately fixed the problem.

Here are the arguments against the hydrogen economy:

       1. Terrestral hydrogen is ONLY an energy
           carrier or transfer media and NOT a
           substance capable of delivering net NEW
           BTU's to the on-the-books economy.

      2. Terrestral hydrogen creation is inefficient
           as considerably more energy of usually
           much higher quality has to be input than
           is eventually returnable.

     3. No large terrestral source of hydrogen gas
         is known. Water, of course, is a hydrogen
        sink and, by fundamental chemical energetics,
        is the worst possible feedstock.

     4. The CONTAINED energy density of terrestral
         hydrogen by weight is a lot LESS than gasoline.
         And drops dramatically as the tank is emptied.
         The energy density of hydrogen gas by volume
         is a ludicrous joke.

    5. Virtually all bulk hydrogen is produced by methane
         reformation. And thus is EXTREMELY hydrocarbon

    6. Hydrogen has one of the widest explosive ranges known,
        the least spark energy required for ignition, and
        has no known colorants or odorants. Its flame is
        often invisible or nearly so.

    7. There is more hydrogen in a gallon of gasoline
         than there is in a gallon of liquid hydrogen.

     8. No effective vehicle compatible means of hydrogen
         storage is known that is remotely as cheap, safe,
         dense, and convenient as carbon bonded hydrides.

     9. No infrastructure exists for gaseous hydrogen
         distribution. Pipelines in particular raise major
         density and embrittlement issues.

     10. Electrolysis from high value sources such as
          grid, wind, or pv is totally useless as a hydrogen  
          source because of the staggering loss of exergy.
          There ALWAYS will be more intelligent things
          to do with the electricity.

    11. Improper burning of hydrogen produces highly
          polluting nitrous oxides.

   12. Terrestrial hydrogen is basically a POLLUTION
         AMPLIFIER that INCREASES the pollution of
         its underlying sources. It is utterly ludicrous to
         claim that hydrogen is in any manner, way,
         shape, or form "nonpolluting".

   13. Hydrogen rots most metals through embrittlement.

   14. "Carbon Neutral" solutions would appear better
         than "Carbon Free" because (A) A significant
         measure of the energy of most fuels is in its carbon
         fraction, (B) Carbon appears to be essential for
         convenient and safe room temperature liquids,
         and (C) Reformation is not required or else
         is simpler, cheaper, and wastes less energy.

     15. An optimal hydrogen storage solution exists by
          carbon bonding as in heptane or iso-octane. Both
          of these room temperature liquids ain't broke.

One of the more intriguing entries in our Gila Day

Morenci Southern Railway.

This long abandoned route ran from Guthrie,
crossed the San Francisco River, then went on up
Morenci Wash to the original town of Morenci.

Easiest access is off the Back Country Byway
about half a mile or so north of the Gila River

If you look at the entire history of all US railways,
there were a total of fifteen well documented
loops in which a train crossed itself in attempting
to gain altitude. Amazingly, FIVE of these loops
were on the Morenci Southern Railway.

Yet another source of endless confusion is
that there are two totally different meanings to PFC
or Power Factor Correction.

IF you have predominately fundamental frequency
sinewaves involved ( very rare these days ), PFC
consists only of shifting the phase of the waveform to
maximize the real component and mininize the
reactive component.
Typically, power companies
will add capacitors to cancel out the reactive
effects of inductive loads.

But these days, you are more likely to have a
rectifier that tries to draw pulse currents out of
the power line. Leading to big time harmonics.
Modern PFC attempts to minimize any harmonics
drawn by making the input current as much of
a fundamental frequency sinewave as possible.

The "old way" simply places a capacitor across
the line. The "new way" involves very elaborate
and specialized switchmode techniques.

The two PFC schemes are most assuredly NOT

There still seems to be some major "not

electronic distributors catalogs over "axial" versus

One more time: As any 1929 radio book will tell you,
axial leads point out the axis. Radial leads point in
the direction of the radius
of a cylinder.

Here is a photo site that shows you the differences.

The two most common types of electroytic
capacitors are single ended axial where both
leads come out one of the cylindrical shape,
and double ended axial where one lead comes out
one end of the cylindrical shape and one or more
leads come out the other end.

Radial leaded electrolytics are very unusual and

We usually answer our phone with the four digits

combining a personal phone system with a number of
business services with a technical help line.

Among other things, we have found that Eastern

Southwestern ones. With some practice, you can
get dialect down to a fractional state area.

Or, in the case of Pittsburgh, within six blocks.

This numeric response also makes a really great scam
, as they instantly lose their place in the script
they are reading. Several key phrases can then set off
alarm bells worthy of a Pink Floyd "money" concert.

Ferinstance "Is this a business?" is a dead giveaway.
There is no need for any legitimate caller to ever
ask this. Never.

"How are you today?" is another obvious scam.
Few legitimate callers will ever ask this, and those
that do will merrily go on with their conversation
even if you do not answer. The key rule is "Whoever
speaks next -- loses!
". Try it. Works every time.

The instant we suspect a scam, we respond with
"What is the purpose of your call?" Any irate

Promptly terminating any foreign call makes infinitely
more sense that spending lots of time patiently explaining
why you are ALWAYS going to terminate any foriegn call

Someone has come up with a new product that might

Should a modern computer fail other than its disk

Should you have an ancient pre-USB computer, the

Our ancient grid systems here in the Gila Valley
are much more extensive than most people even imagine.

Besides highly concentrated northern grids, there are
many isolated and smaller examples to the south. Typically
these are gently sloping near mesa tops in areas with
bunches of loose rocks in the 2 to 10 pound class. The
rocks are typically rounded river cobbles and are not
worth a damn as higher wall construction materials.

Several classes of rockwork are apparent...

     Rectangular grids, often 12 x 25 feet or so,
     singly or in groups. In a somewhat erratic

     Round rockpiles perhaps three feet in
     diameter. Some with internal depressions.

     Arc shaped check dams across small
     drainages, some with distinct downstream

These tend to be well away from habitation sites of
multi room ruins. Potsherds are almost entirely
absent, and lithics are somewhat scarce.

Some of these are masked by more modern
structures such as early Mormon irrigation canals,
CCC projects and even modern rock walls and
rearrangements. In general, the CCC projects are
far more anal and precise. But proper attribution of
simpler structures remains a problem.

My latest discovery is a linear feature that extends
nearly a mile and exactly follows a constant elevetion
topo contour. Calling it a "canal" is premature and it is
not at all obvious what the water source or its destination
was. There seems to be no modern interest in the area.

This photo for one of our latest eBay listings

once again review some of the insider tricks of
image postproc.

The image was first available light photographed
by a 5 Megapixel Nikon Coolpix camera outside

non uniform lighting.

The image was then rotated using Imageview32
and its tilt corrected by our older and newer custom

exposure was done with Inageview32 and Paint.
We probably should have made the knob even
darker with a lower gamma.

The fancy vignette is done with our fully automatic
custom autobackgrounding code. A further gamma
reduction, brightening and very slight sharpening
completes the process.

A reminder that versions of Acrobat Distiller above
8.1 default to PREVENTING file manipulations
. The
usual workaround is to run Acrodist -F off your windows
command line.

Also a reminder that the image must be at your
final crop before doing a vignette.
And that double
exposures often must be at the same magnification
and rotation as the original. Unless you are up to
something special. Such as realigning a cable end.

Our local "Southern Grids" area has an incredible
variety of prehistoric grids, roasting pits, ruins,
trincheras, and such. Some of which are covered

Trouble is that the same area has great heaping
bunches of CCC water control projects. And the
two can easily be confused. More to the point,
it is difficult to accuratly guarantee any particular
simpler construct is in fact prehistoric.

In general the prehistory folks had more potsherds
and lithics. And were much more in tune with nature.
The CCC was far more anal and rectangular. Plus
may have included obvious survey markers or
chunks of railroad rails. Some structures obviously
had an Italian stone mason as a foreman. With
transit accuracy and one inch tolerance.

Sometimes deciding whether you are looking at one
or eight centuries worth of erosion can help. On
lesser features, the distinction is far from obvious.

A further confusion is that depressions attributed to
Mescal roasing pits could in fact have been natural

and caused by the hugely trunked mesguite trees once
in the area. Almost always, though, a depression in
any non-karst area is man caused

Enigmatic are the check dams with downsteam
aprons. At present, these appear in use by both cultures.
one possible explanation is that the CCC liked what they
saw and simply stole the plans.

We looked at the Fundamental Factors Underlying
Technological Innovation
a while back. Another factor
that should be added is fewer mechanical parts.

The breaker points in an automobile were by far
the least reliable and highest repair item. By going
to electronic switching, most service needs were
eliminated. At the same time, timing and dwell
became ridiculously more flexible.

A piano might have thousands of mechanical parts
in it. By switching to electronic synthesis, the number of
moving piano parts got reduced to zero.
And one instrument
can now sound like any size or shape piano. Or, for
that matter, any other instrument. Real or imaginary.

Mechanical adding machines were horribly complex and
hard to maintain.
Not to mention that even such simple
math functions as multiplication or division added horribly
to the system cost. Solid state calculator chips blew these
away completely.

A VHS tape cassette had dozens of parts in it, and the
VCR load/unload mechanism was quite elaborate.
A DVD replaced the cassette with one round piece of
. And the player mechanics reduced to a moving
shelf, a rotating spindle, and a linear positioner.

The DVD itself is in the process of getting blown out
of the water by direct web distribution. With zero moving
parts and incredible flexibility.

Ultra precision rotating disk drives are now being replaced
by thumb drives
and similar solid state flash memory.
With dramatic reliability, speed, and power improvements.

Turning to stuff not yet here yet, compressor based cooling
is an obvious candidate for solid state substitution.
possibly higher efficiencies, less noise, reduced environmental
impact, and far less maint.

Automobiles can use fewer parts by going to electric valves.
Similar gains are to be made by changing to electric power steering
and electric variable rate cooling. Or even no ICE parts at all
by going to fuel cells.

It is surprisingly easy to damage an electric blanket
by kneeling on it or otherwise stressing the internal
wiring. The usual symptom is that it does not heat
as well as it used to. Or not at all.

A plug in wattmeter is the simplest test method.

The power readings should reasonably reflect
your temperature settings. Older controllers will
be off-on style and may draw little standby power.
Newer controllers will switch half power cycles in
or out and may have a few watts of standby power.

An Ohmmeter check will also work if you already
know the expected resistances and pinouts. An
infrared camera also does wonders but clearly would
be overkill.

There's apparently yet another approach possible
for solid state cooling. As championed by the Cool Chips
folks. Trouble is that, at least to me, they seem long
on bullshit and short on products.

Hot electrons apparently will tow heat energy along
with them. By taking an ultra thin vacuum and applying
a positive potential, in theory you can create a solid
state heat pump
. One whose theoretical efficiencies
can be significantly higher than conventional. And
one that can be greatly aided by quantum tunneling.

Using potentially cheap and nonhazardous materials.

All heat pumps are limited by Carnot's Law. My
tutorial on same appears here. To date, nothing
has seriously challenged conventional compressors.
While they have been hampered by less efficient
but more environmentally safe fluids, their efficiency
continues to increase through such techniques
as scroll compressors, computer control, and
variable speed compression and air handling.

The COP or Coefficient of Performance of a heat
engine determines how much electrical energy it
takes to move a given amount of heat
. Resistance
heat has a COP of 1.0. Modern heat pumps with
a reasonable temperature differential may have
a COP of 5 or so. The COP drops with the
temperature differential.

The best of current practice air conditioners
approach 45% of theoretical efficiency, so
there is a lot of improvement still possible. Not to
mention eliminating any noise or moving parts.

Solid state Peltier Coolers have long been
available, but earlier units had a pitiful COP
of 0.15 or so
. The key problem that makes them
utterly useless above five watts or so of
heat pumping is that the temperature rise
of their heatsink above ambient can easily
and grossly exceed their net cooling
. Some
present Peltier research involving nanotechnology
and newer formulations may improve their
capabilities somewhat.

A really cute solid state device is the Vortex
. This is nothing but a Tee shaped pipe.
You blow ambient air in the middle and hot air
comes out one end and cold air out the other.
While mind bogglingly simple, the COP is very
low, there are noise and frost issues, and a
compressed air system is required. Little new
has happened on these in decades.

Another slow starting solid state heat pump is
called Magnetic Refrigeration. Heat energy
can be transferred by switching a magnetic
material above and below its Curie Point.
These have limited temperature ranges,
many of which are well below ambient.
They also involve exotic materials.

There is obviously a zillion dollar market
for an improved solid state heat pump.
Especially one that is HVAC efficient and
cost effective. Time will tell if the Cool Chips
can get their act together.

Farm and ranch maintenence 101:

If it does not move and is supposed to, use WD-40.
If it moves and is not supposed to, use Duck Tape
or bailing wire .

But the foremost secret to successful farming or
ranching is knowing the difference between
"hunker" and "mosey".

As we have seen, not one net watthour of pv photovoltaic
electricity has ever been generated
. And the breakeven
date is clearly falling further and further behind with
heavy new investment in CIGS and related technologies.

Net energy breakeven can reasonably be expected
something like eight years after total fully burdened,
subsidy free panel costs reach twenty five cents per
peak watt
. Until then, the pv panels are clearly
gasoline destroying net energy sinks. And are in
no manner renewable nor sustainable.

Meanwhile, because of the total absence of net
pv energy, not one power utilituy is yet using pv for
routine avoided cost peaking
that is free of subsidies,
credits, r&d or greenie pr.

The so-called "breakeven payback" dates on pv
panels seem to me to be something between a
cruel hoax and an outright lie. I remain amazed
at how many individuals continue to get sucked
into these totally and obscenely bogus figures.

Some considerations...

-- I strongly
    suspect the answer is somewhere between
    zero and negligible.
And "paid" frequently
    means "return on stolen federal and state
    funds", rather than net energy return.

A subsidy is an energy penalty, not
   a benefit. Because of the "iceberg effect"
   the true energy costs of a subsidies admin
   and whatever will be at least three times its
   face value. Thue each $1000 subsidy is at
   least a $3000 net energy loss.
And possibly
   much more.

   is the date at which the entire project has finally
   become totally pointless, rather than being a net
   energy and dollar sink. Only long after breakeven
   do any significant benefits accrue.

-- comapring conventional
  panel technology to, say, eight track tapes
  is unfair because the eight tracks represent
  much more advanced technology than today's
  panels. I strongly feel that virtually all of
  todays current pv installations will never
  reach breakeven. Partially because of galloping
  new technology, and partially becuase many
  property sales tend to disable or de-emphasize
  solar pv installations. And mostly because
  projected breakevens are wildly overoptimistic.

  For many home installations today, the fully burdened
  cost of the synchronous inverter alone can consume
  as much as 150 percent of the total value of the
  electricity sent through it. Assuming free panels.

Expanded our free web television links.

I don't see what the big flap is over stopping analog
air broadcasts, as there is no point whatsoever in any
non-web tv distribution any more.

A tv program is clearly not worth watching if you cannot
start and stop it at your convenience, pausing, replaying,
and fast forwarding. Certainly being expected to start at
a specified time is now clearly ludicrous.

Now, if only they would eliminate the totally arbitrary

One of the real dangers of attempting humor in any
public or semi-public form is "them" not getting the joke.

I was recently appalled at a failed humor attempt when nobody
in the audience had the slightest idea who Dilbert was!

One glance at our local rock grids dating from the 1300's
and their astonishing similarity to the Dilbert cubicals jumps
right out at you.

In fact, If I took my Marcia Swampfelder skills and
combined them with a one time ability to sling the shit
on anthro papers, I bet I could come up with a credible
peer reviewed paper that these were in fact the prehistoric
Dilbert originals.

This would take no more of a leap of faith than most
other archaeological papers routinely make.

A digital camera optimized for Draganfly
use could be made ridiculously lighter, smaller,
and less power hungry than an ordinary one.
But whether the quantities would justify the
engineering is another matter entirely.

Firstoff, you would get rid of the "Heinz
Catsup Bottle" effect
and make no attempt
whatsoever to make the design look like a
classic 35 mm camera. Fixed infinity focus
will work just fine
, eliminating any and all
autofocus needs.

There would be no need for a LCD display
and its ungodly power gobbling backlight.
Nor for a conventional viewfinder. Much of
the digital signal processing could possibly
be downloaded to the base station. With less
than half of the camera actually in the air

And you might actually put a dozen or more
of these on a single platform
, eliminating the
need for pan and tilt. You simply pick and
power the one that is pointed in a useful direction.
most of the circuitry could be shared, so only
the sensors and lensing would be multiple.

The potential for integrating camera and
platform, power and nav here is enormous.

The Direktor of the Ministry of Propaganda for a
major government bureaucracy sends this along:
            “Gila Valley Day Hikes” Topic of  
                  First 2009 Brown Bag Talk


Author and researcher Don Lancaster of Thatcher
will present the first talk of 2009 in the Bureau of
Land Management’s (BLM) popular Brown Bag Lunch
seminar series. “150 Gila Valley Day Hikes” will be the
topic of Lancaster’s talk on Tuesday, January 13, at
noon in the BLM conference room.

The public is both welcome and encouraged to attend.
Bring a lunch or snack and a drink and enjoy the talk
and accompanying audio-visual presentation.

Hikes to be discussed vary in difficulty from easy
walks for families with small children to extreme
canyoneering. Most hikes have recently been verified
for access and conditions.

Anyone that has attended one of Lancaster’s evening talks
at Discovery Park can attest to his knowledge and sense
of humor. When asked what locations will be discussed,
he said “Most hikes are less than an hour’s drive from
the Greater Bonita-Eden-Sanchez Metropolitan Area.

Lancaster has posted brief descriptions of many of trips on
his website at http://www.tinaja.com/gilahike.shtml.

Places to avoid will also be briefly covered.

The BLM office is located at 711 14th Avenue, at the
intersection with 8th Street, in Safford. For more information,
contact Diane Drobka at 348-4403 or Dave Arthun at 348-4428.

One leader in the field appears to be Draganfly.

Their best units appear to be a triangular platform

These remain pricey, but there should be some

Got yet another "nobody is paying attention
to my perpetual motion device
, and its been ten
years now" email. This one involves the usual
square wave from a battery going to a transformer.

Thus proving that they know absolutely nothing
about either square waves or transformers.

Some condsiderations:

     Conventional meters are TOTALLY USELESS
     when measuring unusual waveforms.
Only recently
     have economical true RMS techniques become
     available. Even then, because of crest factor issues,
     doing the power measurement job right may demand
     a pair of ultra high speed synchronous A/D converters and
     a companion digital multiplier.

    There is no such thing as "Pulsed DC". Instead, you have
    the exact Fourier Series equivalent of a continuous dc level
    plus various continuous ac harmonics. Ordinary transformers,
    of course, have no dc response.

    Any simple combination of batteries and transformers
    has already been screwed up by lab students.
If there
    was the slightest possibility of anything overunity
    on simple routine connections of ordinary components
    in normal ways, student mistakes would have found it.
    And done so centuries ago.

   The way electricity and electronics is taught to technicians
   and ordinary students is wildly different from the way it
   is taught to engineers.
There is, for instance, no such
   thing as Ohm's Law. Thus, most of what you think you
   know about electricity is not even wrong. And more of an

  Should you observe an exception to established physical
  laws, your formost goal should be to stop everything and
  go out of your way to prove yourself wrong.
There is not
  the slightest doubt of the outcome here. None whatsoever.

  There is no point in repeating an incompetent experiment
  from a misguided researcher
. If a fundamental simple test
  cannot show a credible theoretical basis for an observation,
  then that observation is wrong. Ferinstance, if EIS researchers
  cannot find overunity in a drop of water, there is no way that
  less skilled individuals will do so driving coast to coast in
  their water powered car.

  A fundamental question would always be "How many people
  would have to be how wrong in how many different ways for
  how long in order for you to be correct?"
Most fundamental
  electronic experiments are inadvertently and routinely run
  millions of times daily. With consistently expected results.

  If you do in fact have overunity, simply connect your output
  to your input.
If you end up vaporizing everything within
  a six block radius, I'll STILL not be convinced. But at least I
  might be willing to look further into your claim.

 The probability that an extraordinary claim is valid drops
  dratmatically with time.
If strong supporting evidence does
  not emerge in a few days or weeks, it likely never will.
  "Publish or Perish" remains supreme in acadamia.

  Finding overunity would be one of the most unimaginably
  henious crimes against humanity.
It would make Hitler
  look like Mother Teresa.
For it would inevitably turn
  the planet into a cinder. If you find a free energy souce,
  you damn well better find a free energy sink as well.
  Even then, the relative flux rates will still nail you.

  The scientific method DEMANDS that you prove yourself
  right, not that others prove you wrong. Extraordinary claims
  DEMAND extraordinary evidence.

One of the handier "rules of thumb" that
sometimes apply some of the time and can be
enormously useful is this:

Very often, one percent of what happens
nationally happens in Arizona

of what happens in Arizona happens in the Gila

Thus, roughly, there are 300 million people in
the US, 3 million in AZ, and 30,000 locally.

Many ranches appear to be for sale on or near
Mount Graham. Some for as little as $45,000.
Here are some typical listings.

Only it is not clear to me exactly what you are
buying. Very often, there is no deeded land. The
fences and corrals may need major repairs, the wells
and springs might range from low to dry, and the
tanks and windmills often need major work.

You do, of course, gain the right to steal grass off
of the state or feds with grazing fees whose rates
are utterly, obscenely, and unconscionably low
. And
basically comparable to outright theft. These are
typically only valid for a few months out of the year.

Grazing fees are approaching one tenth of their
admin costs. And have recently been slashed.
And half of that is routinely rebated.

What you do with your cows ( the few dozen that are
supportable ) the rest of the year is up to you.

There is, of course, no grass because of the drought.

Thus, the payoff these days on both stock markets is
about the same.

I've been revisiting some of our local indian
ruin sites

the Gila Valley has lacked an obvious champion.
Yet its population and influence apparently
were among the highest in the American

The area is confusing to say the least, as
pottery styles represented Hohokam,
Salado, Ancient Pueblo Peoples, Mongollon, and
, among others. Clearly complex trading
routes went through the area.

There were elaborate irrigation systems.
Both from the Gila River and riparian
side canyons. Not to mention many thousands
of water enhancing grids that may have been part of
an elaborate aguave to mescal booze factory.

Or possibly the world's very first prehistoric Dilbert

Many of the sites have been outrageously
pothunted. Others have been obliterated by
anglo constuction.

Modern agriculture has also  trashed the tops
of many sites. But they may lie pristinely buried,
awaiting subsurface radar techniques for modern
excavations. When all is said and done, plows do
not normally go all that deep.

I've always wondered why we do not have
more heat pumps for water heating apps.

With low temperature differentials, a heat
pump can be as much as five times more
efficient than electrical resistance heat.

Sadly, as the temperature differential
increases, the COP drops dramatically
Breakeven is around a 50 degree differential
and an electrical resistance backup has to be
provided for higher differentials

A hot tub or a spa would seem to be an ideal candidate
for a heat pump. With a potential energy savings of
as much as 80 percent. But the available heat pumps
cost something like $3000 custom installed. At a dollar
a day resistance heat costs (10 kw heater for one hour
at ten cents a kilowatt hour ), the energy breakeven
would be something like ten years. Or longer than
a typical spa life

It also seems faintly ludicrous to put a $3000 heat pump
on a $2500 hot tub. "Ten dollar horse and forty dollar
saddle" comes to mind.

Still, an integrated heat pump should add no more than
$100 or so to a high volume tub manufacturer. And
might pay for itself quite rapidly.

Meanwhile, there is a new $500 plus installation
heat pump for ordinary hot water heaters
. But it
seems to me this system has a grievious flaw:
Since the air is cooled, the amount of space
heating has to go up during fall, winter, and
spring months.
For an apparent ZERO benefit.

If the air being cooled is outdoors, the efficiency
will often be far lower. And even during air conditioning
season(s), the benefit is not clear, since the hot
water energy may be released into the air conditioned

Things are rarely what they seem when it
comes to energy alternatives.

There seems to be a revival of interest in
wireless power transmission. The bottom
lines remain that most of Tesla was utter
bullshit, and that severe issues are likely
to forever remain with distance, efficiency,
safety, and sensor comm.

There are three probable approaches. The
first is to use inductive coupling via an air core
. This is the approach used in electric
toothbrushes. The coefficient of magnetic coupling
in air is absurdly low, so distances of even a fraction
of an inch will totally trash efficiency. The amount
of power transferred drops as the fourth or fifth
power of distance beyond a very close in point.

The second approach is to go to a resonant system
similar to a Tesla Coil
. Power levels as high as
60 watts have recently been shown. The coils have
to be physically large and their orientation is
critical. Again, efficiencies are low.

It is interesting to note that there was a well known
but little used resonance phenomen. If you place a
large resonant coil near an am radio, you can dramatically
increase the sensitivity if you tune the coil to the same
frequency as the station being sought. The large size
and awkward tuning largely prevented this from seeing
much popular use.

A third approach is to use a focused beam, similar to
a flashlight or a laser.
The antenna or mirror doing
the focusing has to be many wavelengths larger than
the energy transferred for a minimially divergent beam.
Orientation of the receiver is super critical, for there
will be near zero power outside of the beam.

For even modest amounts of power, there are very real
safety issues with anyone coming near the apparatus.

In addition, because the efficiency is very low, some sort
of two way comm would be needed so that the system is only
active whenever the receiver (such as a laptop or cell phone)
is in need of power.

A practical result may be a foot square plate that you place
a laptop or cellphone or whatever on for recharge. Anything
larger or needing longer distances is likely to remain fictional.

year for predictions, so here goes...

   technology and learning curves are now

  traditional cable and over-the-air broadcasts.
  There is no point for either to continue.

  GYROS AND GPS -- extending to the lowest
  cost, simplest, and least elegant products.

  Creating a humongous bandwidth crunch
  and seriously impacting the very future of
  the web.

  Along with most other magazines and newspapers.
  The economics are now ludicrous.

  IMPROVED WALL WARTS -- Modules only
  slightly larger than an ordinary ac wall plug and
  standardized "one size fits all" wireless schemes.

-- Free internet access at
  ultra high speeds available nearly everywhere
  all the time.

  Revolutionizing the economics of solar
  electricity. We are talking $9 here, not $2500.
  Including new max power optimization algorithms.

  EYEBALL SIPHONING -- New social web
  services continuing to drain interest in
  classic websites and most everything that
  has gone before.

  by aging membership and easier web access to once
  priviledged information and resources.

  most television and video will be web distributed,
  the utterly abritrary distinctions betwen HDTV
  television sets and larger computer monitors should
  vanish entirely. HDTV's in particular must end
  up with greatly improved web nav.
