Wind turbines - wind power

In Europe and the United States huge wind turbines - a familiar element of a country landscape. These beautiful giants are set not only on land but also on water expanses.

1. The idea of ​​using wind power to produce electricity is not new. She was born in the late 19th century, namely the winter 1887-88's, when one of the founders of the American electrical industry, Charles F. Brush built the prototype is automatically controlled wind turbine to produce electricity. At the time, she was a giant - a rotor diameter of 17 meters was equal, and consisted of 144 blades made of cedar ....



2. In Europe, the first wind power station was commissioned in 1900 and the beginning of the II World War II worked on the planet a few million wind turbines.



3. What's inside:



4. Modern wind turbine - a steel tower height of 70 to 125 m, on top of which are installed a generator and a rotor with blades made of composite materials. Today the 56-meter blades.



5. Among the tens of thousands of wind turbines there are huge, and there are small, one house. And this is just a giant wind turbines. Look what small on their background appear at the bottom of the house Photos:



6. One of the largest wind turbines today was built in September 2002, near Magdeburg in Germany. Its capacity - 4.5 MW, each of the three blades is 52 meters long and 6 wide, and weighs 20 tons. Mounted on the rotor 120-meter tower.



7. The rotor windmill:



8. To understand the scale. The blades of the windmill:



9. The latest development of wind energy - wind turbines, rotor diameter greater than the wingspan of the aircraft giant, even our "Ruslan". Such a plant has a capacity of 1.2 MW and is capable of providing electricity to 800 modern residential buildings.



10. Norway announced plans to build the world's largest wind turbine in 2011. Work is already under way. The height of the wind turbine will be 533 feet and a rotor diameter - 475 feet. As expected, the turbine will provide electricity to 2000 homes. Record prototype costs $ 67, 5 million.



11. Currently, the record for the size and capacity (141 meters and 7 MW) wind generators owned by Enercon E-126, located near the German town of Emden.
Installing wind turbine Enercon E-126:



12. In all its glory:



13. Windmills put not only on land but also on water expanses:

16. The highest wind turbine in the world is located in the province of San Juan at an altitude of 4110 meters above sea level. It has established the largest gold company in the world - Barrick. Wind is listed in the Guinness Book of Records.



17. powerful generators have become not harder or larger in size and weight, and more "intelligent».



18. Wind turbine - expensive technology, but the cost of its acquisition will pay off during the first 7 years of operation. Estimated service life - 25 years.



19. European leader in wind energy - Denmark. In this country, they are usually placed on the rocky reefs and shallow water at a distance of 2 km from the coast.



20. The most windy places in Europe believe the Scottish External Hybrids. The northern part of the island is blown constantly. The wind there is almost never subsides.



21. At the end of last year the company Deepwater Wind announced plans to create the world's largest deep-water wind farm.
It is expected that it will be built over 29 to 43 km off the coast of Rhode Island and Massachusetts and will produce megawatts and 1 000, which is comparable with nuclear power. Wind turbines will be installed in the bottom of the ocean with a depth of 52 meters - it's much deeper than any other modern wind power.
