the peltier cells are widely used in automotive drink-coolers and they
are really
efficient in a way : they use waste-heat used for nothing
the altRnator uses the engine's power so it can be 100% efficient - it
uses Xtra fuel

well , I'd be more careful about estimating the ele-power-consumption of
my car
only the front lights are a little above 900 watts :)
(it  helps finding the way ;) )
the audio sys eats up some 200-300 W the stand-heating 40-200 W
the seat-heating ? only saab knows ( I found it in a saab 900 )

the H-O catalist cells are used in space applications
maybe someone can build one for diesel-air it'll be light and extremely
efficient
it must be - according to the books but it states noone has found the
right 
catalisator YET

ps how do would you make a pre-heated water injector for a diesel ?
