New Air-Conditioner Absorbs Solar Energy and Blasts Radiation Into Space

One day, rooftop solar panels could pull double-duty: harvesting energy from the Sun while also cooling the house below. Scientists have created a device that combines two technologies to do exactly that. And while it’s an early prototype, it’s a promising step toward solving the world’s many energy needs. Most people are familiar with the concept of solar harvesting, or absorbing energy from the Sun and converting it into power. There is also a reverse process called radiative cooling, which happens when heat escapes back into the Universe. All objects lose heat in the form of infrared radiation, which is invisible to the human eye. The atmosphere usually reflects this heat back, but a certain infrared wavelength can escape into space... Continue reading…
