Going Green with Hydrogen Fuel Cell Powered...

On a complete system basis, there is NOTHING green about hydrogen.
(I am beginning to think that "Jennylist" is some sort of spammer.)

In general, I agree especially for the home-builder with one
exception, generating HHO as a supplemental fuel feed for an internal
combustion engine will net you an additional 10% gas mileage.
Electrolyzers are about 50% efficient; assuming you had a wind turbine
that was producing more electricity than you needed (I.E. load dumping
a lot of electricity). You could home-build a 50% efficient HH+O
electrolyzers with relative ease, but then you would run head-long
into hydrogen's big pitfall which is hydrogen storage.
Hydrogen is a very "light" gas (small molecules) that will seep
through most materials; it is also mildly corrosive which will slowly
destroy some materials over time. All this can be avoided by the
selective use of materials, but it seems to me growing bio-fuels is a
far better way to produce, store, and use fuels for the homepower
bunch. If you are lucky enough to have excess electricity to dump,
converting it to heat (as inefficient as that is) then storing the
heat is way more productive than storing hydrogen in my view.
My general rule is: anyone who just starts a thread, but never
participates in the discussion, is just a troll, or is advertising
something. For me there are two kinds of people out here, those who
try to help and those who don't exist, "Jennylist" joined my
"killfile" long ago.

The links to the AWEA group no longer work, but hopefully the content
is still archived somewhere.

Not much info there and google couldn't find the AWEA group archive,
with "truck alternators" and "truck tire inner tubes" it sounds more
like a hobby than any to make practical home power, computer modeling
a functional hydrogen system is not all that difficult there's a lot
written on the subject, I've modeled systems for both I.C.E.s and
"Fuel Cells". Modeling either system to be both functional & cost
effective is the problem, and a problem I can't solves as technology
stands, I'm not saying that someone won't solve it someday, but right
now, I don't see the future in the "Hydrogen Future".
For fuel I'm sticking with bio, with decades of practical experience
