Two folks have mentioned hydrogen fuel, and seawater as a source. You
should all realize that it takes exactly as much energy to take water
apart into hydrogen and oxygen as you get back when you burn the hydrogen
in your vehicle. In other words, hydrogen is not an energy source - only a
means to temporarily store energy, making it transportable. Gasoline is
stored solar energy from millions of years ago. Ethanol is stored energy
from recently. To produce large quantities of hydrogen fuel, one would use
electrical power, from nucs, coal burning plants, hydro plants, solar
arrays and so forth. So hydrogen can be just as good or bad
(environmentally and economically) as the source of electricity used to
produce it. The same comments apply to electric cars, of course.
