Gasification is the use of heat to transform solid biomass, or other carbonaceous solids, into a synthetic “natural gas like” flammable fuel. Through gasification, we can convert nearly any solid dry organic matter into a clean burning, carbon neutral, gaseous fuel. Whether starting with wood chips or walnut shells, construction debris or agricultural waste, the end product is a flexible gaseous fuel you can burn in your internal combustion engine, cooking stove, furnace or flamethrower. Or in this case, your DeLorean. OK, how about a Honda Accord?

Gasifiers are nothing new, but this instructable teaches you how to build a small scale version powerful enough to run your car. Since we are talking about dry organic matter here, I suppose banana peels and beer are out—but fueling up on pinecones is still better than paying for gas.
