I'd be very interested in your opinion on this story about two UNL professors studying the use of sweet sorghum as the raw material for future ethanol production.  

 Sweet sorghum's advantages over Nebraska corn are many, he said.
  It doesn't need to be irrigated and goes into dormancy during drought periods.  The ratio of energy produced to energy consumed is much higher than corn, and an acre of sweet sorghum can produce as much as 800 gallons of ethanol.
  Corn's ethanol yield is closer to 250 gallons per acre.

What I like about this is that it is originating academically, not corporate or venture capitalistically.

There are quite a few things with better yields than corn, but most have some other handling or capital issues. Don't know much about sorghum, but I don know that is the case with wheat.
