Carol, I think that's pretty neat. I've already been eyeballing that Santa Fe as a possibility when the old Jeep quits running.

Nicole, the thing is, once somebody figures out there is Lots of Money to be made in hydrogen engines, they'll be readily available. People will always need some kind of energy to power something, so I think the argument that "there's too much money in oil" is just a smoke & mirror tactic to cover up for "we don't feel like taking the time to do research."

Sure, there's a lot of money in oil. But there could just as easily be as much money in methane or hydrogen or what have you.

And as far as environmentally friendly ways to make electricity... we have this thing called the Sun. I think we are WAY behind on solar power research.
