I'd very much like to see their cost basis for $1.30 per gallon. You can barely achieve that with corn at the moment which has none of the costly cellulose breakdown processes that would be involved in kudzu to ethanol conversion.

I can almost guarantee you that significant government subsidizing (through tax breaks and loans) is the only thing making this appear to be a profitable process. Food based ethanol startups flop all the time, and they have a much lower cost of production.

Now that corn is <$4 a bushel, kudzu would be even more impractical and uncompetitive. Once someone figures out a cost effective way of breaking down the cellulose, then kudzu and switchgrass will change the world. Until then they are just a way to milk the government for a couple of years hoping for a break-thru.
