[DeTomaso] Free Hydrogen

[Ken Green]

    Where does the power to make the hydrogen comes from?

    I suppose batteries could be charged at home and used, but I'd like to see the math.  I've seen descriptions of high mileage hybrids that are charged at home to supplement burning gas, and I'm not sure how the cost of the electricity balances, but I assume it's cheaper than burning gas?  It still seems dishonest to quote super high mileage and not take the cost of the electricity into account (maybe they do?).
