Scientists have developed a bilayer passive cooling technology inspired by the way camels stay cool in the hot desert sun. The technology’s bottom hydrogel layer acts like a camel’s sweat glands, lowering the temperature through evaporating water, whereas the top aerogel layer functions like fur, insulating against outside heat while letting water vapor pass through. … Continue reading Camel-Fur-Inspired Technology Harnesses Evaporation to Keep Products Cool Without Power
