NightHawkInLight goes into detail and experiments with DIY infrared cooling "paint" and how the effect works through this 40-minute video.
There's an infrared wavelength that radiates out into space without bouncing back through the atmosphere. All you do is reflect that particular wavelength into the sky. The more you can reflect, the cooler the surface gets.
The video shows how to make reflective microbeads plus a snow-like reflective surface out of calcium carbonate and dissolved acrylic. Mixed together, they make a highly reflective surface for this particular infrared wavelength.
The "paint" is actually a mixed powder of the microbeads and acrylic snow-like material. It has to be mixed with liquid to be sort of blotted on to a surface, and it's fragile.
It's a really neat idea with a lot of promise, especially if you can make it at home.
