Good read. I think the hope for energy independence is clouding a lot of folks judgements right now. Once cellulous technology is advanced, say in another five years, there will be a clear and rational choice for switching to ethanal. It's not an environmental panacea, so I would not expect the tree huggers to get on board even though the use of switchgrass would be effective at reducing run-off and sulfer issues can be addressed. IMO, this is going to be huge for poor African countries without natural oil reserves.
