Sun gifts: Solar tower

If there should be somewhere huge solar towers for electric power generation to happen it should somewhere here — in the south of solar Spain, near to Seville. The commercial thermal solar power station first in Europe — PS 10 — has officially become operational on March, 30th this year. Power of the station erected in Spain, makes 11 megawatt.

№2: PS 20

Hardly later, in April, 2009, Spaniards have erected the second tower, is more powerful than the first twice — PS 20. The principle of work of towers is simple: the field from set of the mirrors tracing movement of the Sun, collects light and directs a sunlight on tower top, heating up a hydrochloric solution which in turn, gives energy to water, transforming water to steam.

Steam runs on pipes and, finally, twists the turbines connected to electric generators. Thanks to presence of the intermediate heat-carrier — salt weight — towers are capable to accumulate “warmly for emergency”.
