Selsam invented a new type of multi-rotor wind turbine (wind generator) success came, the wind turbine rotor 25 (rotating device, wind vane) form, the power generated is 10 times that of ordinary steam, and can greatly lower manufacturing costs, especially for poor regions and developing countries to promote universal access.
The new wind turbines installed at a distance, like a snake dance in the air with the wind, inventor Doug – Selsam to the name “sky serpent.” However, this device in the air using wind turbine generaor electricity has not overlook. The world’s largest wind farm Kinderdijk Netherlands – elshout village, although only a small village, but most of the world’s largest wind turbine. However, in the inventor Doug – Selsam’s eyes, the use of turbine and equipped with the 747 wing-sized wind turbine is very clumsy and expensive. “Serpent sky” is very small leaves, and small footprint, and use of GE’s advanced rotary device (leaf) greatly increased the ability of the equipment acquisition. Selsam that the use of “sky serpent” wind turbines will increase the efficiency per unit of time and greatly reduce costs.
Selsam said, as early as 1000 years ago, humans began the use of wind, and designed the first wind collector. But over the years, the design and manufacture of wind turbines has been in the stage of a cost-inefficient. After his years of research, and Fluid Dynamics Laboratory at the University of California, with the help of the design in the early ’80s out of single-rotor wind turbines. But the years of actual use of the results further show that single-rotor turbine’s efficiency is very low, unable to raise the efficiency per unit of time, and because great covers an area of broad size, installation cost is very expensive. So since 1999, he was funded by the California Energy Commission, began to study multi-rotor wind turbines. In 2000, Selsam design and wind power generators manufacture the world’s first wind turbine rotor 7, and the application was successful. In 2003, he designed and manufactured to provide a 20-rotor 3000 watt wind turbine, a serious test after 20 rotor of this device was soon to be put into the market, and achieved considerable economic benefits. According to energy experts predict that this 20-rotor turbine efficiency increased by 40%, single-rotor turbine of the several dozen times.
Until recently, Selsam in the California General Electric Company turbine test facility has successfully tested his latest design and manufacture of wind turbine rotor 25 “sky serpent.” “The sky snake” is wind energy experts believe that is “crazy imagination,” which not only changed the traditional form of wind turbines and rotor, the number of records broken, the electricity generated is also very alarming. Selsam proud of that: this is only the beginning, will snake across the sky, flying in the sky. It is reported that “the sky snake” cost 25 million U.S. dollars, life is 9 years, the United States than the world famous GE’s small wind turbines confidential stronger and more competitive.

Mr. P Ashok, Managing Director, Leitner Shriram Manufacturing Ltd, said, “It is a very exciting moment for us today. With the international strengths of Leitner Technologies, and Shriram EPC’s local presence, we have been able to set up this Global manufacturing hub for Wind Turbines. This partnership will produce world class gearless wind turbines and enable us to deliver the best in quality for India and the World.” “This partnership is aimed at meeting the needs of the Indian and international customers by offering globally competitive products. This wind turbine generators will help our customers produce quality wind power with high efficiency and low long term costs,” said Mr. Michael Seeber, President, Leitner Technologies Group “Chennai has also proven to be the ideal location for our factory. It took a very short time to get the factory ready and start our production which is very efficient and to our entire satisfaction,” he added. Commenting on the occasion, Mr. T Shivaraman, Managing Director and CEO, Shriram EPC Ltd. said, “Shriram EPC is an integrated infrastructure solutions provider serving the core sectors of the economy and catering to the needs of alternative energy industries.” He added, “Our strong presence in the wind and biomass sectors give us the opportunity to capitalise on industries vital to economic growth contributing to a sustainable and green future. Our joining hands with Leitner has provided us access to a world-class gearless wind turbine and further strengthens our capabilities in this domain.” Shriram EPC, a part of the Chennai based Shriram Group, is a US $ 200 million company that employs over 500 technically qualified personnel including 300 Engineers. LSML Shriram EPC entered into a joint venture agreement Leitner Group on February 3, 2007 for setting up SLL for the purposes of marketing and sale of wind turbines and development of wind farm projects. SEPC holds 51% of the capital of SLL and 49% is held by Leitwind BV. Wind energy has so far been the most developed section in the renewable energy sector in India. Estimates suggest that India has the potential to generate 45,000 MW of wind power while counter estimates raise the bar to anywhere between 60,000-80,000 MW. Currently, the country has commissioned capacity in excess of 10,000 MW. Wind is currently the most competitive source of large scale renewable energy. Since these wind farms are set up in rural areas, it generates opportunities for employment in the form of electrical, civil and mechanical engineers and technicians. The total capacity installed in India is 10,134 MW as of 31st March 2009.

ecently, China’s wind power installed capacity of the Sturm und Drang has become the focus of media attention. However, yesterday in Shanghai at the China-US Energy Forum, there were two distinct voices.
“China’s wind power generation is engaged in” Great Leap Forward “.” Chinese Academy of Engineering Ni, in his speech that the current herd phenomenon may have a more than half of enterprises to be eliminated, resulting in great waste.
“Emerging industries have special laws that only competition can bring mainstream technology and leading products,” Ministry of Science and Technology Development Strategy Institute, executive vice president of the Wang Yuan said: “Now China’s wind power machine manufacturers have more than 80, I think we increase the number may develop into more than 100. ”

As a representative of the emerging clean energy, China’s wind power or not to cool things down?
Explosive growth of the hidden
China 2008 new wind turbine generator sets 5030, the cumulative installed capacity has more than 12 million kilowatts, however, that year only amounted to 12.8 billion kwh of wind power. Ni academicians pointed out that this means that China’s installed capacity of wind power per kilowatt-year, work only 1,000 hours, electricity, a household income of several hundred dollars, the efficiency is too low, and even beyond recovery for investment, not labor, maintenance and other costs.
Ni academician’s worries are not without justification.
Supply unit in the wind, until 2004, China’s wind power machine to do business only six, but the separate ways in recent years, the capital flocking, and the machine has reached more than 80 vendors, leaves manufacturers have more than 50. However, in the first half of this year, to achieve installed capacity of wind power machine manufacturers with only a dozen homes, bulk supply of leaves and only a dozen commercial and industrial competitive situation means that many manufacturers will be eliminated. In the installed capacity, the Ni Academy Wind Turbine on the respect of many in the “sun”, when the decoration, because the characteristics of wind power determines the number of wind farms located in remote, power generation and construction of the high cost of network lines, power grids, the lack of a intention to build electricity transmission network Jie Feng.
Ni academicians believe that wind power construction is an industry chain, the current manufacturing capacity, installed capacity in the “lame” leap forward, because this chain on other sectors such as power grids, wind assessment, is still very lacking, at present most in need are talking about things like breaking a number of key technologies.
Competition is the only way
However, Wang has a different point of view. He believes that only through intense competition in the market in order to select a reasonable price, viable technological path and successful enterprise, without adequate competition, the construction of wind power will not be able to form real business value and rely on subsidies can not be success an emerging industry. “Only competition can bring people to affordable energy, the creation of effective demand.” Wang said.
State Council Development Research Center researcher Xuan Xiaowei has also publicly expressed the view that the development of new energy industries and traditional industries and different, there are a variety of technologies and possible future path in this process, if the manager is thinking of a planned economy , delineation of several key enterprises have high hopes, it is difficult to create a fair competitive environment. National Development and Reform Commission of energy, said Li Junfeng, deputy director of China’s renewable energy growth is rapid, but compared with the overall energy supply in recent years, growth in the proportion of total energy consumption did not increase very rapidly.
The future of wind power where
Well, the wind turbine, “the sun,” What is reasonable? Wang told reporters that the problem lies in the Government not directly involved in the investment competition. However, Ni is also very clear point of view, many of the wind farm owner is a large state-owned power enterprises, the ultimate loss of, or the State.
It is worth mentioning that General Electric (GE), vice president of Maike Yi Decci an interview with reporters yesterday, said that the existing technology only enough wind to support the development of the next four years, four years later the market will turn to the latest the next generation of new technologies, greater emphasis on cost control, low-speed efficiency and other issues, GE China Technology Center has a professional team of more than 100 fans are doing research and development machine. Not only that, despite the financial crisis, but the GE R & D Center in China against China this year has increased to 30 million U.S. dollars R & D expenditures more than doubled last year. This gives China’s wind power industry, businesses large and small wake-up call – “staking their claims,” is important, but only the best adapted to market needs and technological change, businesses will ultimately win.
