My engineer likes to say "all the easy stuff has been done already".
I agree, mostly. It sounds very much pie in the sky. But this bio-based gasoline isn't cheap. In the test they got the cellulose free. They say $1.50 for the conversion per gallon. Refinery costs are about $0.20 per gallon of fossil gasoline. So it is a breakthrough at being only 7.5 times more expensive than fossil gasoline to "refine", but the equivalent cost of cellulose stock is about $50 per barrel of crude oil, which is $86 today.
