Renewable energy is not a new idea. Every elementary school kid knows that methane emanates from the cowpat in the beautiful green field. Anyone with a rudimentary knowledge of South America knows that Brazilian motorists have filled their tanks with ethanol for years. We all know there are alternative fuels available for hybrid cars on both sides of the Atlantic. Now meet Dean Gokel, a NASCAR fuel specialist who knows one source most people may have overlooked. According to Frank Bell, his company's president, Gokel has technology that can "take a gallon of piss, chit and water and turn it into a gallon of gasoline."
