Super detailed, high quality video on radiative cooling coating
Other fun fact is that most white paints are not actually white but have absorbers in them because to have true white paint it has to be very thick. People do not want to have to put on and pay for a ton of coats. So most people never see true white paint. True white is very specialized.
Once had the chance to compare 3 brands of ‘pure’ but still commercial white, and side-by-side differences were pretty impressive. The whitest looked distinctly blue in comparison. My favorite “whiter than white” trick is the fluorescent brighteners in laundry detergent. Absorb ultraviolet, emit blue, and give the impression of bright white.
Yes nice, sky cooling is interesting.
