Engineers create white paint that reflects 95.5% of sunlight

Engineers from Purdue University developed a new white paint using calcium carbonate fillers which absorb almost no ultraviolet rays. It'd replace the need for air conditioning by absorbing nearly no solar energy and sending heat away from the building, researchers said. During testing, the acrylic remained 10°C below surrounding temperature at night and at least 1.7°C lower under direct sun.
