Paint that 'sweats' to keep homes cool without AC created
Researchers have developed an experimental paint that "sweats" to cool buildings without air conditioning. The paint combines solar reflection, evaporative cooling, and radiative cooling, reflecting 88-92% of sunlight and emitting 95% of absorbed heat. Nanoparticles, polymers, and salt enhance durability. Homes coated with it were found to have used 30-40% less electricity for cooling.
