You guys are good at spotting scams, I can pick the obvious but don't know
about this one. Is this another investor scam? Or is there some merit in
what I find to be very vague claims.
I can't say this is a scam as such, but it ain't too bright. If you have an
efficient way of producing electricity, why aren't you SELLING IT TO THE
GRID, where you'll get 10 times the cash you would from selling hydrogen?
Chemosynthesis is a pretty interesting thing, and I think there will
ultimately be a place for it, somewhere. But I don't think, if someone has
made a breakthrough in it, that the first place you'll see it is on a site
looking for investors. *
Efficiency is the key.
Few people realize how diffuse an energy source solar energy
really is. Or how utterly futile it is to try and do economical
conversion with lower efficiency conventional pv cells or emerging
alternatives.
Incoming solar energy in the Arizona desert on a good day is
something over one kilowatt per square meter. And over six
effective hours, something like six kilowatt hours are incoming.
A six percent efficient panel would produce something like 60
watts or 360 watthours per day. At a dime per kilowatt hour,
you would be looking at a whopping 3.6 cents of production per
active square meter per day.
But wait. The panel efficiency is a lot worse than the cell
efficiency. First, if you do not track, you can throw away
something like 20 percent. Then there are the days of
available sunshine, which typically trashes yet more. Then
there is lower incoming for latitudes further north.
And then there are portions of the cell which do not produce
due to wiring and self-shading. And areas of the panel which
do not have cells on them. And panel histories that tend to
degrade through time. And algorithm and conversion losses.
All told, perhaps one cent worth of electricity is producable
per square meter of panel per day with low efficiency cells!
A panel of comparable efficiency that produces hydrogen, of
course, would produce only a tiny faction of one cent worth per day.
BEFORE amortization, of course.
Thus today, even with totally free 6% pv cells, totally free panels,
totally free land and totally free labor, the amortization cost of the
synchronous inverter alone is more than enough to guarantee
you have a net energy sink when full burden accounted.
