(Zap! Another one bites the dust)

Craig Werner gives some figures to show how 1 gal of gasoline produces
about 1 1/2 gal of water.  Part of his reasoning is that "car engines
are about 1/4 effecient," so only 2 water molecules are produced
per gasoline molecule, instead of 8 or 9.  However, I believe that
the engine effeciency is unimportant, since virtually all of the
gasoline molecules react with the oxygen.  The engine effeciency
of approximately 25% is a measure of how much of the energy contained
in a gal of gasoline is actually available to move the car (the 
transform of chemical energy to kinetic energy), not a measure of 
how much of the gasoline is consumed to produce water.
