Alcohol in the gas is not a technical solution; it is a political 
solution.  Several local news stations have tested the effectiveness of 
the alcohol gas by filling up average cars and taking them to an 
inspection station.  The 'oxygenated' gas always performs worse.  Which  
makes complete sense.  If you carefully tune an engine to burn a 
specific type of gas, it will be slightly out of tune for any other.

But alas, corn does bring much per acre, so the pols do what they can to 
prop up the prices.  It doesn't hurt to look like they're throwing a 
bone to the environmentalist in the process.

instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
