附二 Tower of Power ? By Gonzalo García-Sobrinos, Ignasi Salvador-Villà, ICCP, and Jesús Serradilla-Echarri A 115 m high tower is the crowning achievement of PS-10, Europe’s first commercial generating facility to be powered by the sun. Constructed in Spain, the tower has been designed to support large loads, facilitate public access, and complement its surroundings as much as possible.??

Because of their relative novelty, the various technologies continue to undergo rapid improvement, generating new engineering challenges. A recently completed solar power project near Sevilla (Seville), Spain, illustrates this point. Known as PS-10, the project consists of several hundred large movable mirrors, known as heliostats, that reflect direct solar radiation to a central receiver located near the top of a 115 m high concrete tower. Components within the receiver convert the solar radiation into electricity. Because the tower is unique in many ways, its design proved challenging. In particular, the tall structure had to be sufficiently robust to support large loads yet maintain an aesthetically pleasing appearance that would be compatible with the surrounding environment. With regard to the potential development of solar energy, Spain is one of the most attractive countries, as it enjoys the greatest amount of sunshine of any European country. In fact, the Plataforma Solar de Almería is Europes largest center for research, development, and testing of technologies?used to concentrate solar energy. Located in Almería, Spain, the facility is part of the Centro de Investigaciones Enérgeticas, Medioambientales y Technológicas. Moreover, Spain is the worlds fourth largest manufacturer of solar power technology. Several hundred movable mirrors, known as heliostats, below, r
