He’s “recycling” intense heat created by concentrating sunlight. If you had a means of getting to the temps cited, what was it, 2400 degrees, and cooling fins on the other side or outside to create a large temperature differential, I suspect the efficiency would increase substantially.
Inefficient as existing thermoelectric units are, they’re still cheaper than solar photovoltaics. I just don’t know of many who have commercialized the things yet, not for specific use in generating residential electricity. They’re chiefly known from those camp stoves as I mentioned. Outside of that, you’ve got inventors and tinkerers who appear not to be well funded selling them to order in low volume.

Uh huh. Sort of a perpetual motion machine?

They are used in remote locations where reliable generation is required.

How do you recycle the heat if it goes out the cooling fins?
