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.<br /><br />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:<br /> <a href="https://www.google.com/patents/US2984077">https://www.google.com/patents/US2984077<br /></a><br />
