It’s claimed this invention could be used to improve any type of cooling system.
Imagine a device that can sit outside under blazing sunlight on a clear day, and without using any power cool things down by more than 23 degrees Fahrenheit (13 degrees Celsius).
It almost sounds like magic, but a new system designed by researchers at MIT and in Chile can do exactly that says TechXplore.
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.
