"The white coating, a porous paint-like material, reflects up to 97% of sunlight and radiates heat, making surfaces up to 10 degrees cooler than the surrounding air, even under direct sun. This cooler condition allows water vapor in the air to condense like dew on the smooth coating surface, where it can be collected. In a recent test, a roughly 10-square-foot area treated with the coating was able to harvest 1.6 cups of water over the course of single day."
"Solar-reflective paint is hardly new to the world of sustainability, and it's been used widely to reduce heat gain on everything from buildings to UPS trucks to playgrounds. This new coating builds on those applications by taking more advantage of the cooler air produced by bouncing heat off a building, creating a surface onto which water vapor can condense in the cooler ambient temperatures."
A nanoengineered porous polymer coating reflects up to 97% of sunlight and radiates heat, lowering surface temperatures by up to 10 degrees cooler than surrounding air even under direct sun. The cooled, smooth surface causes atmospheric water vapor to condense like dew, enabling passive collection of moisture. A roughly 10-square-foot treated area harvested 1.6 cups of water in a single day during tests. The coating is paint-like and porous, increasing durability compared with typical reflective paints and maintaining surface function over time. The formulation can be applied to building exteriors to provide decentralized passive cooling and supplemental water supply.
