Smart window changes color with weather
Weather could power the next generation of smart windows. Researchers have created glass that tints by harvesting energy from wind and precipitation. The approach offers an alternative to other smart windows powered by batteries, solar panels, and even standard power outlets. "The innovation ... represents a new kind of renewable energy source," says Liming Dai, a nanomaterials engineer at Case Western Reserve University in Cleveland, Ohio, who was not involved in the research.
