Solar Tower:History and Future Projects
About Solar Towers we can talk very much.About first of this towers can be read during 1903 in the "Eelectricity" written by Colonel Isidoro Cabanyes Spanish, and in 1931 in a description made by German author, Hanns Gunthet, descriptions of solar heaters.After 1975 people began to develop projects for solar towers that have been recorded in countries like China, Canada, Israel, U.S.A and Australia.This project is now in the principle of combining solar power with wind power.It is very simple.In top of a tower there is a wind collector that is heated from the sun and this hot air is transmitted to the tower turbine high yield.Project is quite expensive to put into practice. To increase the efficiency of 25% are mounted some channels with water traps heat one day and released at night, so the tower is useful 24 hours from 24...
