Serious question...
Alcohol is much more expensive than gasoline and many think that the EPA has cooked the books on any pollution benefits. Alcohol is a low BTU fuel that is destructive to older cars and small engines. My ATV needs a new neoprene diaphragm every year as alcohol dissolves it. Fuel lines and carburetors parts are dissolved by alcohol in lawnmowers and all maintenance equipment. This fuel is a form of corporate welfare and a political payoff for the Eco nuts.
This is why it won't go away any more than Globull warming. In what sane world could the Navy be required to use fake fuel at the cost of over $200.00 a gallon?
