I have taken General Chem 1&2, Organic Chem 1&2 and Physical Chem and microbiolgy. And 2 more years of chemistry research on bio-diesel from edible oil. Nothing in it tell me that cellulosic ethanol is impossible.
I had General Chemistry, Organic Chemistry, Researched Chemistry, taken all the cehmistry classes University had to offer, and worked on bio-diesel research from renewable resources for my Master thesis. I also had micro biology. Microbs are amazing organism.
I not only think this is possible. It will become reality.
