Researchers have created a paint that promises to cut air-conditioning costs
A team of researchers from Columbia University’s engineering department has a solution for rising temperatures in cities, which they say could drop surface temperatures by as much as 6°C (11°F) and save lives in the process. It’s a very special white paint, developed by adding air voids to plastics, resulting in a thick, white coating that can be slapped onto almost any surface. It’s an example of passive daytime radiative cooling (PDRC), where a surface cools down by reflecting sunlight and heat back to the atmosphere.
