Volkswagen have been experimenting with thermpiles in the exhaust to

Crikey. An alternator is actually a very efficient device. Sounds
like they're clutching at straws.

An automotive alternator is very inefficient. *And not having it
removes a parasitic load from the IC engine.

Harry fantastic, you got it! *Unlike some other seniles. *An alternator can
take 9-15hp off an engine. Remove it, the mechanical parasitical loads like
oil pump,

So how do you propose this new engine will be lubed then?..

water pump,

And cooled unless its so so efficient it runs just warm to the touch?..

a/c,

Well we can always just sweat I suppose..

and the HP of an engine will rise substantially.
Then the engines can be downsized reducing fuel consumption again.

Suppose we'll have to find candles for the lights so the price of
tallow;!.



Just having an alternator with a clutch that cuts out when accelerating mean
the engine can be downsized and acceleration improved. *Also the starter
motors can be downsized as well (cheaper & less weight

That really going the make any real difference how much of a percentage
is that compared to the weight of the battery system. Course I suppose
once the cars rolling on leccy it can be bump started...

and power drawn from
the battery). *All this is easy to do, like the next model update could have
it all - Instead of a 1600cc the engine could be 1300cc.

The ancilliaries all have their own electric motors. They only run to
the level actually needed.
This is old hat. You can buy this stuff now.
