hydrogen as an endless, virtually free, source of energy This point should not be addressed at all. Probably there is no one left who believes hydrogen is an endless, virtually free, source of energy. Instead, the emphasis should be on hydrogen as a clean-burning fuel for cars or for the fuel cells.
I hope you are right, but I fear that many people think the big bad oil companies are suppressing a hydrogen powered utopia. Most general interest articles on Hydrogen are misleading IMHO.
