Intro: Bio travel

Right now I'm working on research for a more environmentally friendly travel option. I commute a lot for work and school and while my conscious is decently assuaged by the fact that I drive a Honda Civic and keep up on its maintenance and drive it (usually) gently, I would like to take it another step further. After watching the documentary, 'Fuel', I have become super interested in lessening my use of gasoline/oil.

My goal is to find a safe, reliable, used diesel engine car this summer and either run it on bio-diesel or convert it to run on vegetable oil. Or something along these lines...

And by the way, if you haven't seen 'Fuel', you need to. Take it with a grain of salt, if you want to, but it still makes a plethora of good points.
