I saw a report on TV a few days ago about Brazil and its efforts to make ethanol. Turns out they make it from sugar cane. It has proven to be a success for that country. With the apparent failure of corn based ethanol looming, I think maybe it would be a good idea for us to take a look at making ethanol from sugar cane instead of corn. I don't know if our land will support the growth of enough sugar cane to get it accomplished, but I did read on Yahoo that Florida bought the land from our largest sugar cane producer. Here's a link to what wikipedia has to say about sugar cane based ethanol.
