Checking my understanding here: in a very simplified sense, is this saying that we’re taking energy, be it from ambient temperature during the evening or that plus solar radiation during the day, and essentially bottlenecking/‘forcing’ it to radiate in the spectrum that’s atmospherically transparent and can thus escape to space? Seems the use of insulating it in a vacuum would be to minimise heat loss until it’s cooled to the respective temperature that radiates in that specific spectrum.
Incredibly cool (hah) paper to read, thank you.

- _nalply 3y agoYou should take an infrared thermometer and point it to the clear sky. If the sky is very clear, you will get temperatures much lower than ambient. You just let heat radiate away, and this is enough to cool.
