There are _so_ many better processes which could be used to make
these alternative fuels (for instance, using algae to create
biodiesel). But we're also talking about processes which are in
their infancy. I don't doubt that, if researchers and engineers had
as long to improve the yields and refinement of biodiesel and
ethanol as they've had for gasoline, their production would be much
more efficient. Heck, some of the older diesels can run on straight
vegetable oil. Their fuel does not have to be of such high quality.
