Henry Ford envisioned that ethanol made from plant matter would be the best way to power vast new fleets of automobiles. Besides Henry Ford, didn't Rudolf Diesel originally design his engines to run on vegetable or seed oils, not petroleum? Funny how ideas that we think are new are actually quite old. They even had electric cars way back then.
