As I wrote the other day, the USDA has been working on jet biodiesel since at least 2001. I contacted one of the Ph.Ds in charge of the research, Robert Dunn, asking about an update for AutoblogGreen readers (because we fly from time to time, right) and he sent back a nice, succinct response.
The public is slowly waking up to the idea of putting soybeans or corn or, soon, watermelons into their cars, but how long will it be until we feel the same about airplanes. As we've covered recently, the Air Force and Virgin are two organizations looking into alternative fuels for planes (the Air Force, though, is using fuel from gasified coal, not a biofuels). AutoblogGreen reader Drew recently sent in a tip about the USDA's research into biodiesel jet fuels.
