I agree but that's not bio-diesel. (if you are referring to the post above you)

Any biomass can be run through diesel motors; soy, algae, etc. Any biomass, any diesel motor. by now many know that the first diesel motors were built to run off vegetable oil but then they found petroleum was more plentiful.

Either way, with the latter, you can even build your own 'bioreacter' (all it takes is sunlight and a decent CO2 supply (fish)) in the backyard and push your own auto fuel.. heating oil.... possibilities are endless once energy production is distributed. That's why i'm dying for something like the Opel Eco Speedster. High petroleum prices don't have to mean the end of autosport. Small, light, aero-dynamic turbo-diesels ftw!

Not if you're going to talk about ethanol production, check out brazil. They use cheap crop for ethanol and have one of the world's first sustainable bio-fuel programs. It's not rocket science, our govn't is just not interested... well their interests just lie with those who helped them into office.
