Mei Yu Jian one thousand meters of solar tower power use for 200,000


According to the U.S. life science network reported in the American Southwest future there may be a "solar tower", which is a new concept for energy production, it looks like a giant chimney, but it does not release harmful smoke gases, but through the solar heated air, and convert them into electrical energy that can 200,000 residents.
   
 Similar designs proposed solar installations for over 20 years, the basic design prototype called "flexible solar panels Collector", for heating the air near the earth's surface, the heated air is guided into the high central tower, the turbine located at the bottom of the tower manufactured by updraft out of power. Australian Energy Task Ltd. Jim Ford said, "The solar tower design combines chimney, rotating turbines and greenhouse, and ultimately the production of electricity.

 Limited by the Australian Energy Task design up to 1 km of the solar tower, the U.S. government is likely to accept the design concept and plans to build in the American Southwest. Solar Tower is an updated version of the solar chimney, solar chimney is a long history of technology, the use of solar heating to form a natural updraft of air, thus creating electricity.
   
   Ford said that the physical design of the solar panels china tower is very similar to the atmosphere vortex engine, an artificial vortex heated air into the air chimney device, even if the vortex will extend over one solid structure, but the structure of the solar tower power conversion design enables generation.

   In 1982, a small solar tower built in Spain that Thorez Mansa district, the tower height of 195 meters, is a transparent conservatory awnings around the transparent canopy cover diameter of 244 meters. It was originally used as a test prototype, the maximum output power is 50 kilowatts. This small solar tower built using inexpensive materials, the purpose is to use the lowest construction costs, but in 1989 during a storm in this solar tower was eventually blown down. Ford told the American Life Science Network said, "By contrast, the Australian energy company designed solar tower tasks using concrete structures, the sustainable use of at least 50 years.
   
   Currently, the company not only plans to build energy task more rugged solar tower, also plans to build solar power tower higher, which can be ground and the top of the tower to achieve a greater temperature difference, temperature difference is large chimney structure can provide a more powerful suction capability. Ideally designed solar tower height of 800-1000 m, and its diameter 1.5 miles surrounded by a conservatory awnings. Ford said, "This is the ideal solar tower structure, along with the prices of carbon fuels, solar tower will be more commercial advantage.
    
   In a sunny day, the solar tower at the top of the air can reach 20 degrees Celsius, on the ground conservatory awnings air can reach 70 degrees Celsius, when the hot air to 34 miles / hour (about 55 km / h) speed up along the Solar Tower , the 32 rotating turbine will produce up to 200 megawatts of electricity. Although in this operation, the solar tower convert solar energy into electrical energy efficiency is only less than one-tenth of the solar panel. However, the advantages of solar tower is easier to maintain and less costly.
