However, windows are not something people typically associate with being a cutting edge1 technology. Research

64、ers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a flip of a switch2.“It took us a long time to figure out what a window really is,” says Claes Granqvist.
