Use that plant material to make ethanol instead.

I've been reading up (out of curiosity) on wood gas. And you can set it up to run on gasoline/ethanol to get the firing process started then switch over to wood gas (via switches/valves in the car) after a few miles of driving. Making the startup not so elaborate procedure.

There is a study by the university of alabama showing comparable emissions to gasoline on an older (90's I think?) dodge v10 and 37% more efficient than gasoline.

I have to leave for work, but I will find the link to the study.
