    Ethanol can be made from many different plant sugars including starch and cellulose. Starch ethanol is the most common biofuel used in the world. It is made from kernels of corn, which is very easy to break down. This means that corn is very easily converted into ethanol. On the other hand, cellulose is not easily broken down into ethanol. Cellulose is found in the cell walls of plants, and resembles plant armor. The cellulose combines with lignin, which makes plants woody. During the process of

    Ethanol and Gas Prices Do the gas prices frustrate you every time you pull up to the pump? Gas companies are charging too much for the natural resource that is turned into what we know as gasoline. Gas companies discourage research and new ideas every year. Afraid of losing the market that they have cornered they buy patents. This way the patents will never be used and they still have the market cornered. Ethanol is a much safer and more economical solution to our gas problem. It is cleaner
