Biobutanol is already available at a "barge" (bulk) price of around $3.70 a gallon according to David Ramey's site.

Gasoline is already above $3.00 and apparently headed for four by peak summer, so assuming it is possible to scale up production with some government sponsored "heavy lifting" (very doubtful!) to convert ethanol production plants it would be sensible to simply load up right now and just go as is. Once gasoline hits four, butanol is a deal, n'est ce pas?
Yes I know it ain't that simple, but I'm waiting to see who pops the balloon now that I've let it fly.

I already chowed down on the 14,000 gallon annual oil consumption figures of the island nation of Saint Vincent and the Grenadines. It would seem to me that an operation capable of producing that much is a no brainer.
For St. Vincent it would be a lifesaver as gasoline is currently NINE dollars a gallon right now.
Straight butanol at the 55 gallon drum price of $6.80 would be a frigging bargain.

I wrote to Ramey about the idea but he hasn't responded.
I'd LOVE to see him guest post here as I think butanol might have real shot...MIGHT being my hope that "other factors" don't step in with the intention of "stepping ON".

I doubt that this can be bio-butanol, for reasons I will get into in an upcoming post. Probably conventional petrochemical butanol; the kind I used to make.

Mr. Rapier I am thinking it would be great to get Mr. Ramey in on TOD in some capacity for your upcoming article. I don't know about the others but I'd be thrilled to get his input and your assessment of same.
