Rudolf Diesel, inventor of the patented moder Diesel Engine. In 1900 he created a new engine that he wanted to use to replace his own design as the Diesel engine was 'dirty' as he himself was aware. His NEW engine ran on ANY unrefined oil. He used unaltered Peanut Oil in his demonstration. He died mysteriously on a boat before he could patent it. some claim he was murdered to save the petroleum industry. His "oil" engine is still not in use. Ethanol is NOT the same.
