High Temp Thermoelectric Generator
High Temp Thermoelectric Generator
(OP)
I am looking for a high temp thermoelectric generator. It would need to be a Peltier type generator. I would like something that could tolerate a constant temperature of 500 deg C on the hot side, but might consider something that can handle a lower temperature.

When I read this news, I had assumed that they were using the 'old fashioned' two metal junction system (Seebeck effect). The system would have to be installed up near the headers to see any heat, but that part of the exhaust can be glowing red hot under full load.
Are Peltier diodes capable of surviving 500C? If not, then look at bi-metal junctions.

There must be a trade off over mV produced vs Material resistance.

Does anyone know some good references for designing something along those lines?

If we learn from our mistakes I'm getting a great education!

But then again it would be hard to keep the heat from the cold junction.
I know they use propane powered generators for some remote telecom sites in BC, I wonder what they use.

Doug's museum of retro tech has a thermo gen section
