A peltier effect element should be usable as either a heat pump or a generator depending on whether you apply a current or a temperature differential.  The images in the linked document are of a similar device I have seen used as a TEC and I understand the hot side of the usual spec units can't be driven above 80C, quite possible it could go higher in generator mode.

Also fun trivia - check the name on this original TEC patent filed back 1958 before semiconductors were really much of a thing, clearly a name only a cool guy would have:

in mind, I am look for the TEG (thermoelectric generator) kind, not TEC
kind often recovered for thermoelectric cooling.

I just need to borrow it.

Thanks,
Cere
