A new wearable fabric can help people survive the impacts of massive heat. It stayed 4.1 degrees Fahrenheit cooler than the broadband emitter fabric used for outdoor endurance sports, and 16 degrees Fahrenheit cooler than commercialized silk commonly used for shirts, dresses, etc. It might be used in buildings, cars, food storage and transportation, lowering internal temperatures and reducing the cost and carbon impact of air conditioning. A thicker version of the fabric protected by an invisible layer of polyethylene used on the sides of buildings or cars, could lower internal temperatures and reduce the cost and carbon impact of air conditioning. The material could be used to transport and store milk and other foods otherwise spoiled in the heat, cutting refrigeration’s impact.
