Researchers at Purdue University have developed the world’s whitest paint, capable of reflecting 98.1% of sunlight—enough to cool buildings without using electricity. The paint’s secret lies in its high concentration of barium sulfate, a compound also used in photo paper and cosmetics, combined with particles of varying sizes to scatter light across the full solar spectrum.
Unlike traditional white paints that reflect less and still absorb heat, this paint drops surface temperatures by up to 4.5°C (8°F) below ambient levels. It has the potential to dramatically reduce energy consumption, especially in cities facing rising temperatures and higher demand for air conditioning.
Already recognized by Guinness World Records, this innovation could help slow global warming, cut utility costs, and even extend to infrastructure, vehicles, and spacecraft—all by simply brushing on a layer of ultra-white science.
