The device I saw was 8 off 80 watt pielter devices, clamped together with the cold junction of one in contact with the hot junction of the other, in series thermally, and connected in series electrically to 72 volts dc at 8 amps, giving a device of about 600 watts. They quoted that it got down to a few degrees K. I'm trying to find the reference, before the internet was around.
I also tried a GEX 34 germanium diode, in the focal point of a 1 meter ex tv dish I scrounged (This would have been over 50 years ago, when I was 1 teenager), and fed that into a audio amp, basically ,making a crystal set that operated at microwaves frequencies, much like the early Police radar detectors. Sun noise was no problems, but the interference from terrestrial radars from ships at Port Kembla wiped out the detector regularly.
