*Rudolf Diesel, the inventor of the diesel engine, designed it to run on vegetable and seed oils like hemp. In fact, when the diesel engine was first introduced at the World's Fair in 1900, it ran on peanut oil.
*Two decades later, Henry Ford was designing his Model Ts to run on ethanol made from hemp. He envisioned the entire mass-produced Model T automobile line would run on ethanol derived from crops grown in the U.S.
*Even in the 1920s, the oil industry had massive lobbying power in Washington. Lobbyists convinced policymakers to create laws favoring petroleum based fuels while disgarding the ethanol option.
*Nearly a century later, amidst oil wars in the Middle East, Global Warming, and a nearly depleted oil supply, the U.S. government is finally shifting attention to fuels that are more along the lines of Diesel and Ford's original ideas.
*In an interview with the New York Times in 1925, Henry Ford said: "The fuel of the future is going to come from fruit like that sumac out by the road, or from apples, weeds, sawdust -- almost anything. There is fuel in every bit of vegetable matter that can be fermented. There's enough alcohol in one year's yield of an acre of potatoes to drive the machinery necessary to cultivate the fields for a hundred years."
