Every now and then it's nice to see a topic that is not controversial.I was surprised to see it powered by hydrogen since the big drawback for hydrogen powered cars is the energy density of stored gas. It takes a much larger device to store the energy than say gasoline or even batteries. I can see the advantage though of using it at 65,000 feet. The natural expansion would eliminate any fuel pumps. Really cool stuff.
