You can use 100% ethanol if you put larger main jets in your carburator. Don't 
know how you would accomodate with a fuel injection system. 

As for the "more than a gallon of gas to produce a gallon of ethanol" 
statement, the same has been said about biodiesel, but only AFAIK by one 
researcher who seems fixated on discrediting alternative fuels.  I haven't 
seen any other studies to back his contention up. 

The other issue with ethanol is how you produce it. Fermenting corn is only 
one way of producing ethanol. It is also possible to begin with cellulose, 
digest it by chemical or even fungal or bacterial means, and then ferment it 
into ethanol.  So you could produce ethanol from grass, or from the corn 
stalks rather than the ears, or from sawdust, etc.
