Cooler than cool

The newest way to go green at home could be with a simple coat of paint. A team of engineers at Purdue University created the whitest paint in the world. It’s so white it could reduce the need for A/C (hello, lower energy bill). That’s the goal, at least. Where typical paints absorb heat, this ultra-white formula reflects 98.1% of sunlight while releasing infrared heat. Because it absorbs less heat than it emits, the paint leaves a surface cooler than its environment. And with a cooling power of 10 kilowatts, it could replace household air conditioners in some homes. There are similar paints currently on the market, but they only reflect 80-90% of sunlight, and they can’t cool surrounding surfaces. Both of which are key for reducing global warming.

This method of energy conservation isn’t new. New York has already coated nearly 10 million square feet of rooftops to fight high temps. And Los Angeles has dropped $40,000 per mile to paint streets white. Turns out, black asphalt consumes 80-95% of the sun’s rays — cooking an already hot city. This new, ultra-white paint isn’t available for sale quite yet, but the researchers and their partners are working on bringing it to a store near you.
