    There's not nearly enough surface area on the roof of a practical car, and anyways, you can make much use of our limited production of solar panels by putting them on a roof where they can always be exposed to the sun when it's out, always at an optimal angle (instead of flat),.

    The parent's post, by the way, is starting to sound like perpetual motion.  Hydrogen is way overhyped enough as it is.
