"Cool Coat" -- The Discovery Files
"Cool Coat" -- The Discovery Files
Columbia engineers have made white paint whiter -- and cooler -- by removing white pigment, and have invented a polymer coating, with nano-to-microscale air voids, that acts as a spontaneous air cooler and can be fabricated, dyed and applied like paint. Research in Arizona showed that the coating reduced air temperatures under the coated surface by 11 degrees, which suggests the coating could help stem energy costs from cooling in a rapidly warming world.
