The problem is if you use a gallon of Ethanol to produce 0.99 gallons of
Ethanol all of the fuel produced will go into production and you are
going to have to add .01 petro just to break even.


Although there are scientists who claim their research shows a negative
production efficiency, there appear to be an equally impressive number
who claim otherwise.


Does it really matter if it is so close that informed people can't agree
it the energy balance is slightly greater or less than 1? Clearly it
isn't much of an alternative fuel if that is the case.



Since my post, I looked up those references to Brazil.

THEY think it is cost effective.

To the tune of 1.8Billion savings.
To the point of converting several hundred small aircraft engines to run on
ethanol,
and to the point of developing a designed-for-ethanol *new* aircraft.
