What I want to know is how this is different from thermoelectricity. I remember a picture from the early 1960s, showing how to make a tiny Seebeck-effect DC source with a coffee can, two different types of wire (say, copper and steel), and a candle. This was for powering a short-wave radio receiver for educational use in some underdeveloped country.
(I used to have a small "intended for use in the car" Peltier-effect refrigerator. I wanted to keep in in the computer room so I could keep beverages and snacks cool. But to run off mains power it used a rectifier brick, which produced enough RF interference to mess with my computer. I was tempted to try to run it off a bunch of D cells.)
