Nice business.
Must be raking in money.

Its highly leveraged at present - so, like Churchill I find I must
rely on allies I don't particularly trust or like! lol. But we will
prevail, that's for sure.
Hey William, have you seen this paper?
http://www.hionsolar.com/n-hion96.htm
Please check out a more reliable source
http://gcep.stanford.edu/pdfs/hydrogen_workshop/Schultz.pdf
Thanks. Thats a very interesting link.
And accurate.
They describe a direct-thermal solar to hydrogen process where they
achieved 1 to 2% efficiency.
Interesting. Thermal cycles using nuclear or solar sources have
demonstrated over 60% efficiency. I have a hybrid cycle using sulfide/
sulfate - that is 55% efficient.
The interesting part was the section
near the end talking about efficiencies of various methods.
The Stanford paper is a more reliable source of information.
Probably more up to date. I don't remember seeing a date on the one I
posted a link to, but apparently the state of the art has progressed
since.
Obviously.
Apparently, the solar-to-hydrogen efficiency obtained using silicon
photovoltaic cells and an alkaline electrolyzer is about 6%.
That efficiency has been achieved certainly. Is it the highest
efficiency possible? No. As I said, I have a hybrid system that is
55% efficient, which is less than the peak of 60% - however, my system
is the lowest cost per watt.
The
conversion efficiency for a solar dish Stirling generator combined
with an alkaline electrolyzer is 19%.
Stanford and General Atomics report 60% efficiency - my system is only
55% efficient, but has the lowest cost per watt of any other system.
The long term solar-to-hydrogen
efficiency goal established by the National Renewable Energy
Laboratory is 25%.
This was true 20 years ago. That value has been exceeded recently by
more than double.
Now you come along and say you can achieve 55% thermodynamic
efficiency
Yes. Its a hybrid cycle - involving BOTH eletrolytic process and heat
with a sulfide/sulfate process.
with a device that is relatively inexpensive to boot.
Yes. The MEMs PV/Electrolysis 'dot' unit is 0.775 cents per square
millimeter ($547 per 300 mm wafer) and operates at 2500x solar
intensity -which means a square meter of collector contains 400 sq mm
and adds $3.10 per square meter to panel system cost.
How much precision do you need to get the 2500X light beam to hit
right on the little dot?
I'm at about 16% of the limit for this material.
How much precision is possible with a PET
hot press molded shape?
Well, one can go through the relevant optical calculations, but since
we can't even get heat engines right, around here, lets take another
route.
This isn't an optics issue its a manufacturing issue.
When you manufacture an optical device, its an optics issue. You
don't know what you're talking about here. Think clearly about your
objection.
What kind of
tolerances do you need and what kind of tolerances can the process
provide with mass production.
Optical tolerances - surfaces accurate to a quarter wavelength of
light - these are routinely mass produced with PET - lens covers, for
automobiles, reflectors for flashlights, packaging that looks shiny
and bright.
I suggest reading Optical Manufacturing by R. M. Scott specifically
Applied Optics and Optical Engineering, Volume III. of that set,
edited by Rudolf Kingslake. Published by Academic Press, Inc., a
subsidiary of Harcourt Brace Jovanovich, New York, 1965
Please understand, we are use about 1/6th of the tolerances we are
capable of to matain a 2400x increase in solar intensity from the
solar disk.
Consider a hot press molded package, or a blow molded water bottle..
They're both very shiny, and smooth and attractive as packaging
material because of that. PET is a preferred packaging material
because of its optical qualities. This derives from their optically
smooth surface. Plain polyethelyne is dull by comparison - that's
because the surface is not optically smooth. Obviously, they're
precise enough.
I don't know the answer but that sounds like
a potential design challenge.
Because you don't know, you can't really say - you are merely looking
for roadblocks in an effort to sound smart - as a consequence you
reveal your ignorance. On the positive side, you openly admit your
ignorance which makes you easier to take than others who don't admit
such, or worse yet, aren't even aware of what they do not know.
The lenses consist of 2 sheets of 100 micron thick PET hot press
molded into lens shapes - and bonded together in a water bath to
encase water - which is the lens medium. The focal point is inside
the lens medium. The water also reacts at the dot when illuminated.
A square meter of two PET films each 100 microns thick contains 200
cc of PET massing 350 grams costing 0.15 cents per gram totalling
$0.53 per square meter. Water cost is nil. Total cost is $3.63 per
square meter. At 1,000 watts per square meter solar influx, and 55%
efficiency, this generates 550 watts for $3.63 - which 0.726 cents per
peak watt.
This is just the cost of the solar panel. The entire system - runs on
average $0.07 per peak watt - which is expected to drop to $0.02 per
peak watt as volume increases.
Your
efficiency is more than double the long term goal.
Long term goal 20 years ago has been doubled recently - you are
absolutely right. I would suggest you read a more current, and more
reliable source of information - such as Stanford and General Atomics
and current DOE literature.
This seems like a
huge breakthrough.
It builds on a number of improvements.
As long as you have your designs protected by
patents, why don't you publish some results in a peer-reviewed
journal?
They already have been published as you can see in my reference.
You say you don't like the allies you have to rely on.
They're the best ones I have - hell, sometimes, I don't even like my
kids - that doesn't mean I don't love them and cherish them.
If
this breakthrough is real
Fuck you.
Easy killer.
No, fuck you for gratuitously calling me a liar.
Bill what crawled up your ass?
You gratuitously stating I was a liar.
When did that happen?
When you implied for absolutely no valid reason that I didn't do the
work I said I did.
