Herzliya-based SolCold has developed a potentially game-changing paint that uses the rays of the sun to activate a cooling mechanism, providing air conditioning without electricity. The double-layered coating uses nanotech to absorb the hot rays of the sun and re-emit the energy in the form of cold. The hotter the solar radiation, the more the coating cools down, making it an electricity-free solution for sunny climates, and usable anywhere from malls to homes, offices, cars, planes, chicken coops, hothouses – you name it. Trials are on their way. The paint could decrease electricity consumption by up to 60 percent, according to SolCold.
