This site is my nephew's who is engaged in grad school research on cellulosic ethanol in the Midwest. He designed the site as a way to sift through the vast amounts of information coming in about the emergence of the ethanol industry, is using it to bring clarity to his own discussion/research (chime in on it), and hopes it can help others to understand some of the realities of ethanol in the process.
