Turbocharged cars seem to be able to use the compressor to stuff more air in without prohibitive amounts of restriction on the exhaust. I could see there might be a way to make it work.

The biggest problems would be heat, and gearing the 100K RPM of a compressor wheel down to something that a standard alternator or generator would work reasonably with.

Could be insurmountable problems, sure. But I don't think that warrants including this in with all the other unicorn poop.
