Here’s an interesting article in the Seattle Times about current thinking within the aviation industry regarding the prospects of biofuels ever replacing kerosene as the fuel of choice for powering planes. The message, as ever, is don’t get your hopes up…

“You would have to plant an area the size of Florida with soybeans to provide a 15 percent blend of jet fuel” for the whole U.S. aircraft fleet, said Dave Daggett, who heads energy and emissions research at Boeing Commercial Airplanes’ product-development unit. “Clearly that’s not going to be appropriate.”
