Check this out, via Instapundit, via somewhere else. It's a study of various alternative fuels. Pretty in-depth, very interesting, and quite possibly a big part of our future. Although at this point I expect the singularity to change everything before we really run out of gas.

Someone described the singularity as "the geek rapture," and I admit to feeling like an evangelist when I talk about it. Local cable access, like the Wayne's World show, not national like Jerry Falwell or whoever is big these days. Has anyone coined the term "netevangelist" yet? Hmmm.... A quick google search shows that I'm way behind the curve on that word. I guess it's obvious. Singularevangelist? Too long, but it is original, so I claim it.
