Anyway, the one thing that they glossed right over was that it takes more
energy to extract hydrogen from water than you get from the extracted
hygogen.

If solar power is used to disassociate the H & O2 water atoms, there
is no pollution generated, and only sunlight, that would otherwise be
wasted, is consumed. Of course, it might be more efficient to
directly store the solar power in a battery for use in an electric
vehicle. In any event, the question becomes, does the production of
solar cells consume more energy than can be expected to be generated
by them over their useful life span?
