It’s basically a mirror that reflects heat from the sun away from buildings. But it doesn’t stop there, it actually takes the heat from INSIDE the buildings and sends it off into outer space. Professor Shanhui Fan and research associate Aaswath Raman published this energy-saving idea in the journal Nature. “This is very novel and an extraordinarily simple idea,” according to Eli Yablonovitch, a photonics pioneer who teaches at UC Berkeley. “As a result of professor Fan’s work, we can now [use radiative cooling], not only at night but counter-intuitively in the daytime as well.” This is made possible be...
