Smart Window Blocks Heat, Generates Electricity......

        Windows in buildings can be a significant source of energy loss because of the hot and cool air that can be lost through them.

       Buildings are going green and so it’s no surprise that researchers are working to develop smarter windows.
Among the smartest is a window designed by researchers at Shanghai University, led by Yanfeng Gao, which does triple duty: It’s transparent, regulates temperature fluctuations and doesn’t require external power to work.
