Well, we don’t use beets for fuel because you can’t get those big cans into the gas tank.

[QUOTE=Chronos]  
Correct me if I’m wrong, but what we want from a plant grown for cellulosic ethanol is just a whole bunch of biomass, produced as quickly as possible, right? And isn’t that exactly what you get from a plant that puts nearly all its energy into spreading? It seems to me that the thing to do is to figure out what the dominant weed or weeds are for a particular area, and then grow that.

And if it’s ragweed I want a cut of the Claritin-D sales in the area.

Then we’d have gas made from kudzu. It might be a close-run thing between kudzu or those ubiquitous “Lose Weight! Call This Number” fliers.
