Metal mirror makes window switch from light to dark in seconds
from Chemistry World
Scientists have made smart glass that switches from transparent to black in one minute thanks to a reversible metal coating process. The material is so cheap and easy to make that it might replace other smart window technologies. Smart windows can be switched from transparent to tinted and back again. As they block visible radiation, as well as infrared, they can help save on heating or air conditioning costs. In buildings, smart windows can reduce energy consumption by around 10 percent compared with regular windows.
