We start out with a given input, then we convert it to the type of energy we want.

- It also works because a single basic HEV motor can do the job of both a starter and an alternator in less weight than the starter and alternator combined.

Actually, perhaps that was oversimplification on my part.
But do note: There are diesels that can achieve hybrid-level efficiency while moving (while idling, no). I've driven a few of them.

Quite agree with that. It's frustrating that the major stumbling block for better efficiencies is the consumers' "need" for powerful engines, bigger cars and ever more luxury and convenience. I've driven traditional cars that can get between 55-70 mpg... but which would never be accepted by the mainstream market because they're too small and too cheap.
