i believe in Biodiesel and Ethonall, as it is more stable and safe than a compressed gas in a can, with a exception Ethonall burns hotter and gasoline, and is more sensitive to air and fuel mixture, it will give farmers more jobs, and Corn and other plans you can extract Ethonall is a renewable resource.
Same with Biodiesel, Rudolph Diesel designed the diesel engine to run on all sorts of different oils, the first diesel engine ran on peanut oil, and the right diesel engine could run on just about anything Oil. Used motor oil, Canola oil, Vegetable oil, Peanut oil, Olive oil, Soy bean oil, Hemp oil, and straight up Diesel Fuel. emagine after a oil change just filtering out the oil and dumping it in the fuel tank, or when your done cooking your bacon, filter it out and put it in the fuel tank. and once again, a renewable resource in most cases, the Automotive market limits diesel engines use to Diesel fuel, only beacuse it would effect the Oil companies.
