TE devices are SPECTACULARLY inefficient. Carnot's Law applies and the thermal tolerance of all TE material are limited. You are lucky to get 5% on a good day

TE devices are SPECTACULARLY inefficient. Carnot's Law applies and the thermal tolerance of all TE material are limited. You are lucky to get 5% on a good day. You still still a heat source and cold sink just like ALL OTHER heat engines and the efficiency is limited by the difference in temperature. There is no cheating. There is no magic.
Selenium is moderately available but it is toxic waste when you need to replace it (all things have finite lifespans) and then need to dispose of the discard.
