A fuel cell is a "battery". Where lead acid batteries require electricity to
charge them, fuel cells require a fuel to "charge" them. Now, let's say you
have 100 kWh of electric from a generator, and you charge a battery bank, that
is more efficient than taking the same 100 kWh, electrolysing w
As an aside, I am puzzled as to why there is so much emphasis being
placed on the "Hydrogen Economy" at the moment, especially by the US
government. Hydogen is just a way of storing and transporting energy,

Donald,
One very important part for biofuels that you forgot, is the positive
effect on job creation and the village economy. It is possible reselling
and creation of income for the village. Maybe the following can give you
more ideas.
