The recipe for making crude oil is relatively simple: combine the remains of ferns, jellyfish, and dinosaurs; cover with sediment; bury deep in the earth's crust; and apply pressure for millions of years-give or take an epoch. Or if you're pressed for time, run some turkey parts or used tires through the thermal process owned by Changing World Technologies of West Hempstead, NY. The system uses water, pressure, and heat to convert organic material into clean fuel gas, absorbent carbon (like that used in water filters),  minerals for fertilizer, and a crude oil that is chemically similar to a mixture of diesel fuel and gasoline; this oil can be sold to refineries and converted into fuel. The system produces no polluting emissions, and the only by-product is water.
