Solar Tower
Solar towers are huge constructions that are created by many segmented mirrors close to the ground and a great receiver placed centrally in a high position. The tower is used in power production applications and usually coupled to highly efficient power blocks. In 2010, Alexopoulos and Hoffschmidt (2010) performed a preliminary work about the possible operation of a solar …

Solar Updraft Towers
In a large solar updraft tower, the collector raises the air temperature by about 30–35 K. This produces an updraft velocity in the tower of about 15 m/s at full load. It is thus possible to enter into an operating solar tower power plant for maintenance without danger from high air velocities. Loads on the Tower. The main wind, seismic, and settling loads on the …
