Saltwater Crops For Food, Fuel?
One concern with the increased use of biofuels (such as corn-based ethanol) is that they use up arable land and drive up the price of food crops. The Los Angeles Times brings us the story of a researcher who's looking for ways to grow crops for both food and fuel in areas with poor soil and a lack of fresh water. The scientist, Carl Hodges, grows a crop called salicornia, which he nourishes with seawater from a manmade canal. The paper says Salicornia seeds can be squeezed into cooking oil, ground into high-protein meal or even converted into biofuel.
