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.
