South Korean scientists have developed a new "smart" window that switches from summer to winter mode. The window darkens when the outside temperature is hot and becomes transparent when it gets cold in order to help capture heat from the Sun. The researchers said their method allows for an instantaneous switch from opaque to a transparent window.
