The idea is a
large, centeral engine is more efficient (less oil, less expensive,
etc) than millions of individual CO dumping engines....

Think of ethanol as a battery (stored energy) rather than raw crude and
it will probably be easier to understand.

Fine, except that the argument is that the ethanol production (analogy
to large central engine) is -less- efficient.
