I have fantasized about this for quite some time. Then I ran the numbers on it: pricey. Still, it'd eliminate a parasitic drag on the engine, and could conceivably generate enough current to run even a hybrid's recharging cycle - hell, stick the Peltiers on the engine block, radiator, everything. Anything that gets warm, make that heat do something useful.
