Maybe we need to start a thread on alternative fuel conversions. Anybody see that PBS special on hydrogen fuel a while back? It was a real eye opener. Iceland is generating electricity from thermodynamic (volcanic, hot springs, etc) sources and using the electricity to generate hydrogen from seawater. They are on a national plan to become 100% hydrogen fueled within a few years and to become a major exporter after that.
Some fella (here in U.S. - the guy that invented the lithium battery 20 years ago) has developed a metal foam substance that bonds the hydrogen and when an electric current is applied, releases it. That means you don't need a high pressure tank of a highly volatile gas. (Don't need 100 million Hindenburgs running up and down the road!) This guy's vision for his invention is that automakers will fill cavities, like frame components with it. It will add structural integrity to the frame and double as a safe fuel tank.
A few years ago a prominent national leader (won't mention any names... don't wanna go there!) called for the US to pursue a national hydrogen fuel program. Nothing has come of it, and I wonder if the backbiting nature of politics here has caused this person to focus on political survival over other concerns. Maybe after the elections are history we'll hear about it again.
Guys, don't turn that last bit political on me. This post is about FUELS. (not fools) :p
