This is technology take makes me very interested in using it, for all the right and wrong reasons. Apartments and homes share one thing in common: they use energy. Some more so than others, but scientists at Lawrence Berkeley National Laboratory have developed a new smart window that lets people choose what they want to let into their home, filtering out visible light, near-infra-red light, or both. Basically, you could bask in the light of the sun, without the heat beaming through the windows, which prompts you to turn on the AC, and wasting energy in the process.
The feat is achieved by a layer of nanocrystals in the glass, that change states when activated with electricity. The result? The scientists at Berkeley are in the early stages of commercializing the new technology.
