iirc the stuff on probes is ~90W of TEM. I know a lot of people say "it's hard to cool stuff in space" but blackbody radiation is a thing. It's all just photons

iirc the stuff on probes is ~90W of TEM. I know a lot of people say "it's hard to cool stuff in space" but blackbody radiation is a thing. It's all just photons, in the end. the TEM just takes the high energy particles and slows them down enough to be "light" and takes a bit (10%?) of the energy from doing that and uses it to charge batteries. Kind of.
