[NightHawkInLight] has been working on radiative sky paint. (Video ... This isn’t the first time he’s demonstrated infrared cooling, but the previous demonstration used Barium Sulfate ...

If the cooling efficiency scales with temperature differential, the expected radiative cooling would be 175W/m2, or about 4.26W per 15.6cm2 cell. That would reduce the thermal load about 20%, for ...

An exciting field of materials science lies in radiative cooling materials, things which reflect so much incoming heat that they can cool down from their own radiation rather than heating up in ...
