‘Whitest ever’ paint reflects 98% of sunlight
Researchers hope their “ultra-white” paint can save energy by reflecting sunlight from buildings. …
Commercially available white paints reflect between 80% and 90% of sunlight, according to lead researcher Prof Xiulin Ruan from Purdue, in West Lafayette, Indiana. “It’s a big deal, because every 1% of reflectance you get translates to 10 watts per metre squared less heat from the Sun,” he explained.
