Provided a market demand remains firm, some automobile manufacturer will make a line of vehicles available with an engine optimized to ethanol.
Saab came out with a car earlier this year that performs better on ethanol than it does on gasoline. The folks in Brazil are doing this as well. We've got to get fuel independent one way or another or our country's economy will crumble. But it appears that I'm preaching to the choir here.... Have a good night.
