Butanol looks promising but I think his statement is a bit over optimistic. 
 The wiki article specifies a 14.6:a A/F ratio for gasoline and 11.1:1 for 
Butanol.  The car will run but it will be a bit lean.

For alcohol fuels to be viable economically they will have to develop 
techniques to use cellulosic materials rather than just corn syrup.  As a 
friend 
of mine says, extracting hydrocarbons from cellulose is like trying to 
extract cement back out of concrete.  It can be done but it takes a lot more 
capital investment.
