Airplanes of the future could run on hay9/20/2012
Futuristic planes should be powered by super fuels or energy-emitting crystals, like in a comic book or something. But French scientists working for the “ProBio3” project, an EU initiative to find new biofuels for aviation, are turning to one of the oldest fuels in history: straw. Straw and sawdust could be treated to create a hydrocarbon similar to fossil fuel and be mixed 50/50 with kerosene, they say, and this biofuel would use a part of the hay that’s not food, so it wouldn’t affect crops grown as feed. Now that feels like a comic book: farmers pitching hay and thinking "Ah yes, gettin' the hay ready for the old jet-fuel plant." [Source]
