IF you really need POWER Generator

I suggest Thermoelectric generator..

it turns IR(heat) into power...

Think outside the box

a 45Watt version will be almost $800... you could hook it upto the output of the exhaust...300C will give you about 45watts of power

That has also been discussed before. The problem with thermodynamic generators is the cooling side. You simply need an enormous cooling fin.
On top of that TEGs are very expensive for the power they produce, so only make sense in applications that run continuously. Most cars are used less than 10% of the time.

People always say peltiers are too fragile.

Since the early-2000s, nearly every major automaker and exhaust supplier has experimented or studied thermoelectric generators, and companies including General Motors, BMW, Daimler, Ford, Renault, Honda, Toyota, Hyundai, Valeo, Boysen, Faurecia, Tenneco, Denso, Gentherm Inc., Alphabet Energy, and numerous others have built and tested prototypes.

They started a seven-year program with Ford and BMW: https://www.greencarcongress.com/201...-20120928.html

My 2017 Civic does it too, nice feature to have.
