According to the report from the United States "discovery" magazine, the scientists from University of London recently invented an "intelligent glass." It is warmer in winter and cooler in summer indoors by using it. The glass may selectively absorbed the infrared ray to maintain the room temperature comfortable and pleasant.
        Why does the "smart glass" have such a magical effect? Scientists said that the secret lies in the thin layer material coated on its surface -- a mixture of tungsten and vanadium dioxide. When the weather is cold, vanadium dioxide can absorb the infrared radiation, and Produce thermal effects, thereby enhancing the indoor temperature. In contrast, in the hot weather, in the thin layer mixture, the two elements of sticky substances together produces corresponding changes, then occurs infrared reflectivity, as a result, the temperature becomes cool indoors.
        Currently, there is a certain distance away from large-scale production of intelligent Glass, but it is reported that the smart glass will be listed after five years.
