A large amount of new technology and new products have appeared in the recommendation activity held in Haikou Hainan which have draw visitors’ attention. The multi-function solar power saving glass developed by scientists from National Taiwan University of Science and Technology has functions of heat insulation, power generation and automatic cleaning and was called “miracle glass” by industry colleagues. It is introduced that this kind of glass is composed by semiconductor layer, vacuum layer and thermal insulation layer, and the semiconductor chip can absorb 70 percent heat of irradiation. When installed on the building in summer, it can save 50 percent cost of electronic power, while in winter it can save 30 percent of heating supply.
