Not to argumentive but I am constantly reading artic;es such as : wwwbusinessweek.com/magazine/content/06_33/63997076.htr that says that 2009 will bring online cellulose plants and that sawgrass and other cellulose products will produce far more ethanol than corn per acre (seven times). Brazil has perfected the process and uses sugar cane and sugar for their independance from oil. There is also a new process sponsored by Berkshire-Hathaway (Warren Buffet) that makes oil and ethanol from all kinds of waste with two plants up and running. When this process is absolutely perfect look for it to be franchised to local goverments which will then be able to do away with their landfills.
