CALIFORNIA: Stanford University in California researchers formulate a new solution to help building residents feel cool during hot days, they invent a super thin multilayer material, which reduces heat in summer.
The engineers call this system “photonic radiative cooling.” It offloads infrared heat and reflects sunlight from buildings.
Study co-author Shanhui Fan, an electrical engineer at Stanford, said that the coldness of the universe is an enormous resource that we can benefit from the new coating material can be used in areas that don’t have access to electrical power.
The new material they invented consists of seven layers witch thinner than the thinnest sheet of aluminum foil and is collectively just 1.8 microns thick.
