Device cools buildings without electricity by sending heat into space
July 2019 was the hottest month ever recorded, according to the National Oceanic and Atmospheric Administration. Such heat waves are only going to become worse and more frequent with a changing climate. As the world gets warmer, demand for cooling is surging, bringing with it more greenhouse gas emissions.
A new system that can cool buildings without using electricity might help. The cooling system, reported in Nature Sustainability, absorbs heat from air and sends it through the Earth’s atmosphere into outerspace. Unlike past systems that work on that same radiative cooling concept, it uses low-cost materials that could be easily made on a large commercial scale.
