Tench Re..You still need a source of energy in order to extract hydrogen from water (the only renewable source of hydrogen out there). Not necessarily. Some of the fuel cells use methane as a source. In addition, many of the new cells use gasoline, but extracting the hydrogen, doesn't create a lot of the pollutants, burning does. So while cells use gasoline, the emissions are different, and supposedly more environmentally friendly.

This is the fundamental problem with a hydrogen-based energy system. Unlike what most people think, hydrogen is not a source of energy in itself. It is only an energy-storage medium. You still need a source of energy in order to extract hydrogen from water (the only renewable source of hydrogen out there). I also understand that hydrogen is fairly unstable and does best when its linked to another element like O2. ted

Coal or gas power plants? Kind of defeats the goal of getting away from fossil fuels. Nuclear power? Only two-bit dictatorships (and France <G>) would want a nuke plant in their backyards. Yup- I'm aware. The administration's funding is going towards extraction of hydrogen from coal, nuclear reactors and natural gas. My vote is for fuel cells, but that's still quite a bit down the road. But, I think we'll get there. -Z
