Informations and news about wind turbines
Wind power is currently the fastest-growing source of electricity production in the world with about a quarter of a million wind turbines operating around the globe in over 90 countries. We now have an output of 336 GW (June 2014), with wind energy production at 4% of total worldwide electricity usage, and growing rapidly; this has prevented 518…
General Electric has installed its 1,500th wind turbine in Canada, bringing the vendor’s fleet capacity in the country to 2GW in four provinces – Alberta, Nova Scotia, Ontario and Quebec. The landmark turbine is a GE 1.6MW unit with a 100-meter rotor for China Longyuan Canada’s Dufferin wind farm, the developer’s first wind farm in North…
In 1913, Nikola Tesla discovered Tesla turbine was produced again in today’s technology. Tesla is a really genius smartest person i have ever seen. He invented AC Current Generators and Motors, Radio, Fluorescent, Radar, MRI, Laser Technology, Robotics Technology, Earthquake Machine and many more in fact, it can be used today, thanks to science, man. I think Tesla is clearly the best scientist. How does the Tesla turbine works ? Wind…
Aerodynamics is the science and study of the physical laws of the behavior of objects in an air flow and the forces that are produced by air flows. Different types of wind turbine blade The front and rear sides of a wind turbine rotor blade have a shape roughly similar to that of a long rectangle, with the…
We know about turbines something less or more but have you ever think about how big wind turbines can be? Norway has announced plans to build the world’s largest wind turbine. The turbine will measure 533 feet high with a rotor diameter of 475 feet. With that big size will also come big power – the turbine is expected to…
Another type of turbine developed at about the same time as the Darrieus was the Savonius turbine, developed in Finland by S. J. Savonius. This is anothervertical axis machine which needs no orientation into the wind. Alternative energy enthusiasts often build this turbine from used oil barrels by cutting the barrels in half lengthwise and welding the two halves back together offset from…
The Darrieus wind turbines was patented in the United States by G. J. M. Darrieus in 1931. It was reinvented by engineers with the National Research Council of Canada in the early 1970’s. Sandia Laboratories built a 5 m diameter Darrieus in 1974, and has been strongly involved with further research on the Darrieus turbine since that time.…
Horizontal-axis wind turbines (HAWT) have the main rotor shaft and electrical generator at the top of a tower, and may be pointed into or out of the wind. Small turbines are pointed by a simple wind vane, while large turbines generally use a wind sensor coupled with a servo motor. Most have a gearbox, which turns the…
We know that there is enough wind globally to satisfy much, or even most, of humanity’s energy requirements – if it could be harvested effectively and on a large enough scale. Vertical axis wind turbines (VAWTs), which may be as efficient as current horizontal axis systems, might be , simpler and significantly cheaper to build and maintain…
(Reuters) – The world will have enough wind turbines to generate more than 300 gigawatts of power – the equivalent of 114 nuclear power plants – by the end of the year, industry figures show. As Brazil, China, Mexico and South Africa add turbines, the figure represents modest growth compared with a year ago, when the overall total capacity was just over 280 gigawatts. “Worldwide installed…
