Generator on the roof of a high-rise building

Using solar cells is a way of recovering a renewable source of renewable energy. But another ' classic ' way is to focus the temperature to generate electricity through steam turbines still applied in some places. With a high-rise building built in the desert, just ' overlap ' the roof of a solar power tower.

Almeisan Tower in Dubai is also a solar thermal power plant. (Photo: internet).

That is the idea of ​​Almeisan Tower designed for Za'abeel Park in Dubai, a major city in the United Arab Emirates.

This tower is a multipurpose home that includes a panoramic view of the magnificent Dubai city, a café, a children's library, a cultural center and a luxurious Conference center. The solar reception place on the top of the tower, the architecturally unique shape consists of a cluster of mirrors rotating in the direction of sunlight.

Heat due to light is concentrated at a focal point, heating up the sodium block to melt (at 500 degrees C), which leads through the boiler causing water to flow through to evaporate, turning the turbine to generate electricity. This generator with a capacity of 600 kW provides not only enough for the units in the building but also for other buildings in Za'abeel Park.

Using the sun is not based on a light source (photovoltaic principle) but through a heat source radiated by the Sun (thermal principle) is not a new idea. Because now in the US there is technology called eSolar, which is being applied to many factories, and in recent years Spain has also used it to produce network power.

Solar thermal energy is generally well-suited to a very cheap population of electricity users, making a one-time investment for permanent use in harsh sunny desert areas in the Middle East like Dubai. The highlight of this building is ' Three no ': No solid waste, no CO2 emissions and no external energy needed.
