I'll bite. Why do you think ethanol is expensive to produce?
Corn must be planted, cultivated and harvested. It must be fermented and purified by distillation. Waste products must be removed and the ethanol must be stored in a waterfree environment. It is somewhat difficult to store and recombine with gasoline.
At the moment it is only competitive because of substantial tax exemptions and federal subsidies.
Surely the price will decrease as the marketplace finds creative solutions to some of the cost issues---using cellulose as feed material instead of starch for instance.
And I certainly advocate continued research and use of Ethyl alcohol as I advocate the conversion of coal to oil and bio diesel. I believe that having sufficient fuel of all types for the U.S. is a matter of national security.
Oil must remain our mainstay for decades to come however and the government needs to take common sense measures to allow its continued development (e.g. allowing drilling on the continental shelf and building more refineries.
