Researchers at Purdue University have created the world’s whitest paint which reflects 98.1% of solar radiation while also emitting infrared heat, as reported in Business Insider. Because the paint absorbs less heat from the sun than it emits, surfaces coated with it are cooled below the surrounding temperature. If successfully commercialised, the paint could be used to coat roofs and walls to reduce or even eliminate the need for air conditioning.
