Certainly, the idea of turning a waste product into energy can be even more intriguing than that of growing and harvesting a plant. But, in either case, the bottom line has to take into consideration weighing the output (benefits) against all of the inputs (costs).

I'm no scientist but, this one sounds silly (even if oil is $80/bbl).

I don't see why it sounds silly, except I think it would take a ton of energy to convert wood to sawdust. Why not just grow that crack grass or whatever that one kind of grass is that is grown for burning?
