- Scientists in Sweden have created a liquid that can absorb solar energy and store it as a thermal fuel for as long as 18 years. The fluid works like a rechargeable battery, but instead of electricity, sunlight goes in and heat comes out when it's needed. https://amp.cnn.com/cnn/videos/business/2019/11/20/liquid-sunlight-gec.cnn-business 215 comments science
