A device was developed that can sit outside under blazing sunlight on a clear day without using any power to cool things down by more than 23 °F (13 °C). The device, which has no moving parts, works by a process called radiative cooling. It blocks incoming sunlight to keep from heating it up, and at the same time, efficiently radiates infrared light — which is essentially heat — that passes straight out into the sky and into space, cooling the device significantly below the ambient air temperature.
