Can I replace an alternator with peltiers?

[JockoT]

They polish the insides of ports to increase flow. I feel that any intrusion, however aerodynamic, would have an influence.

Wait a minute, why is this not used as AC in cars???

Ammonia is bad for health in case of a crash?

With a setup like this you would have virtually free unlimited AC in the car. You could also use it on the peltiers as previously described.



Edit:
It appears feasible.

But it seems it is not convenient for most people as they would rather have instant cold.

If I were living somewhere tropical or where it is hot all the time, i would definitely be looking at installing something like this on a car.

I don't have ac in my truck anyway so that's not a problem for me!�� That's also why I thought it might work better for power generation over ac. Next thing I want to try is making a gravity motor run the water pump.����

Serpentines around the exhaust pipe are likely to be easier to implement than a jacket. Anyway, it might be also possible to put a protective casing around that setup, eventually insulated to improve the efficiency.

Besides the peltiers, if the ammonia system is not too heavy the replacing the AC with such a system would be very good for us who run the AC for 6 months.

I'm not sure how heavy it would be, but an uncle of mine had already expressed some intention to do a similar setup in one of his cars. But anyway, it's still likely to be still lighter due to the absence of a compressor and pulleys, and also nearly maintenance-free.
