Hi All,
It's been a long time since I've participated in a forum. I was last here in 2015 I believe. After extensive patent research in thermoelectricity, my focus has narrowed to some important forgotten technologies that would make thermoelectric generators (TEG) far more efficient than they are currently--efficient enough to replace current heat engines completely, and more efficient than even the best solar cells. Since such devices inherently conserve heat, they seem ideal for our current climate situation. If there's some interest, I'll go into more detail about the technology.
