Bottom line: hybrids get the best gas mileage at present. Diesels are
close behind and may always be a bit cheaper to buy, but not quite as
good for mileage, and also have issues with pollution. Ultimately -
decades ahead - hydrogen is the future. Where the energy to produce
the hydrogen comes from is a whole other ball game :-).


If we don't have the energy to extract the hydrogen, then what makes it "the
future"? I've never understood that angle - "we will need hydrogen for when
we run out of oil" - but we need oil to extract the hygrogen, eh?

Seems to me like we need "something" as an energy source for when we run out
of oil, and what kind of fuel one would generate for transportation would
depend a lot on what that "something" is. Might be H2, very possibly won't.
