The drawing you see here is poet's apdy named Project Liberty. In the lower left-hand corner, baled corn stover stacked five high in rows is being fed into a grinder to start the process of making ethanol from cellulose, the stuff that makes cell walls in plants. It's the most common organic compound on earth, with huge potential to replace petroleum. And poet, the nation's largest maker of corn-based ethanol, is as close as any to doing this on a commercial scale. It's been making cellulosic ethanolfor two years now at a 20,000-gallon pilot plant in Scotland, South Dakota. Its larger 25 million-gal-lon-a-year cellulosic plant in the drawing will piggyback onto poet's existing 55 million-gallon corn ethanol plant at Emmetsburg, Iowa (shown in the upper right corner of the drawing).
