How can one possibly create electric energy with heat?

I’m not talking about converting water into steam or burning gas to rotate electric generators. Those days were over I believe. I’m talking about “Thermo Electric Generators”. Okay, now What is this Thermo Electric Generator?

Thermo Electric Generator

Thermoelectric generators (TEG) are solid-state semiconductor devices that convert a temperature difference and heat flow into a useful DC power source. Thermoelectric generator semiconductor devices utilize the Seebeck effect to generate a voltage. This generated voltage drives electrical current and produces useful power at a load.

How Does it Work?

A TEG is made of p-type and n-type semiconductors. These p-type and n-type semiconductor elements are doped with positive…
