Passive Radiative Cooler is Built Using Common Household Items
LOS ANGELES, Nov. 30, 2021 — Using “Scotch tape” and aluminum foil, engineers at UCLA built a passive radiative cooler that lowers outdoor temperatures without electricity or refrigerants. The team’s cooler design exhibits solar reflectance, long wavelength infrared (LWIR) emittance, and optical selectivity that is comparable to leading radiative coolers, the engineers said. The readily available materials with which the cooler is made, combined with its ease of fabrication and performance, suggest
