SolCold has developed an innovative, patented, nano-technological material that cools everything under the sun, without any power consumption! The material uses the sunlight and the sky for cooling and is most effective when it is very hot and the sun is strongest. The material can be used as a coating for cooling cars, silos and tanks, buildings, containers, apparels, airplanes, etc., bringing tremendous savings in cooling and air-conditioning expenses and significantly reducing greenhouse gas emissions.
