As summer turns to fall, many people will be turning off the air conditioning and firing up heaters instead. But traditional heating and cooling systems are energy-intensive, and because they typically run on fossil fuels, they aren’t sustainable. Now, by mimicking a desert-dwelling chameleon, a team reporting in Nano Letters has developed an energy-efficient, cost-effective coating. The material could keep buildings cool in the summers—or warm in the winters—without additional energy.
