The concept of using other fuels is neat to me. I've been studying up on bio gas digesters and all kinds of bio fuel makers on the web. We waste a lot of things that could be turned into clean energy and maybe even solve some of our garbage problems at the same time. It's not going to happen over night though, but  if done right it shouldn't even cause people any discomfort during the transition while at the same time creating new jobs and opportunities. If you've ever been up in the moutians and come back down you'll see how much automobile polution stinks. You don't smell it normally because your used to it and always surrounded by it. It stinks! I was still a long ways away from any big cities when it hit me. It's everywhere I guess except for high altitudes.
