I wonder if it could be worth it to make one of those on other planets/the Moon one day. No birds to worry about there.
Not a lot of atmosphere on the moon.
Transmitting heat across distances in effectively a vacuum doesn’t work too well.
Just look a the size of the radiators the ISS has to have, and they’re not even sending heat anywhere in particular, that’s just getting it off station
You’re getting thermal radiation and convection confused. The ISS has giant radiators because it’s a right pain in the ass to turn heat into thermal radiation, and it cannot rely on convection to cool things like you can here on earth. Turning thermal radiation into heat on the other hand is pretty trivial. Just don’t reflect it and it’ll turn into heat. These things aren’t transporting heat across distances. They are transporting thermal radiation across distances. That works as well in a vacuum – if not better – as it does on earth.
If thermal radiation doesn’t work in a vacuum, how is the sun heating anything up?
I stand corrected
The mirrors on Earth don’t transfer the energy using the air between the mirror and the collector, they just bounce the spicy photons which can travel even better in a vacuum.
Or in the Atacama, the Desertiest desert on earth!
Where the gigantic Cerro Dominador Termosolar Power Plant opened a couple years ago.

Solar panels are still cheaper and easier. Most spaceships and probes rely on them.

Yea, I should have guessed as much.
