Capturing waste heat from diesel engine....

[DaltonASU]

I'm looking to capture waste heat to generate electricity. my first idea was to use a centrifugal supercharger but in effect use it in reverse, by changing out the compressor blade for a turbine blade and using the pulley to drive a generator.

One of my concerns is that the centrifugal supercharger will not be able to deal with the heat, and break down very quickly.

Another concern is that the geometry inside of the supercharger won't allow for proper flow.

I have tried doing research to see if something like this has already been done, but so far i haven't been able to find anything. If you have ny knowledge it will be extremely helpful. thank you very much

ANY mechanical coupling, be it hard, or be it magnetic, WILL load the engine, and you are not, therefore, using "waste" anything, but actual power from the engine, that would have gone to doing whatever its primary purpose was. AND, you still have the lost waste heat.
