Low-cost wind power can provide a new wind turbine Abstract: The first generation of commercial proliferation of enhanced wind turbine (DAWT) in New Zealand has just begun trial operation two years, if the developers to achieve the expected results, this new design of wind machines to be significantly reduced cost of wind power. New Zealand in the distance about 100 km Aokelannan the Waikaretu on top of a hill, a revolutionary new wind turbine is a two-year trial operation. The wind machines and the appearance of conventional wind turbine completely different compared to its height of 17 m, much like a Juwu squatted on the Peak, and the conventional wind turbine is a slender body, tall and towering over the top of the hill. This is put into operation the first generation of commercial proliferation of enhanced wind turbine (DAWT: diffuser augmented wind turbine), if the developers to achieve the expected results, will lead to significant reduction in the cost of wind power. During the trial the new wind turbine technology, can also test the proliferation of Central Cover new materials, high-strength fibers to strengthen the steel reinforced concrete. Such wind turbine on the ground referred to as "concrete wind turbine." In business, it is called Vortec7 of wind machines, because it has a 7 m in diameter rotor. Wind machines from nearly 100 small investors, set up a private company - Vortec Energy Limited responsible for the design and construction, the company raised 3.5 million U.S. dollars development of the prototype. Vortec Energy Limited is currently being further raise about 700 million dollars to build two sets of rotor diameter of 20 m of the unit. One of the new units will be in areas of high wind speed test, probably in the vicinity of Wellington, New Zealand, the average wind speed in another area. South Australia state government said that the design has a lot of interest in Adelaide and will speed up the installation of an average wind speed near the crew, because the state government that is a rare wind of renewable energy, the need to promote technical breakthroughs-state advantage of the more Lower average wind speed resource development. Two new type of rotor diameter of 20 m of the unit after the successful operation, Vortec Energy Limited will consider the possibility of Nasdaq Stock Exchange. Vortec7 unit performance data show that the rotor diameter of 20 m below the design to 0.031 U.S. dollars / kWh the price of Internet access, it will enable New Zealand and wind power can compete existing power plants, and other new methods of power generation compared to more Competitive. If Vortec function of wind power generation in this price level, in the development of wind power will rapidly become a powerful new force. Vortec Energy Limited is the backing of entrepreneurs Robin Johannink, he successfully operating a series of operations, but also Pacific Lithium (an extract from seawater lithium companies) backing. Johannink, said Vortec technology is an international product, but the technology in the New Zealand stock market was on the recognition and attention is not too high, in this difficult market. Therefore Vortec Energy Limited is considering the Nasdaq in New York Stock Exchange listing is likely to achieve in 1999. A proliferation of technology U.S. aerospace giant Grumman Space Company (now Northrop Grumman Corporation) spent eight years developing the proliferation of technology and a proliferation of enhanced wind turbine technology patents. It was the spread of a detailed analysis of fluid dynamics and the use of a 5 m in the wind tunnel model confirmed the results. The proliferation of wind turbine rotor in the lower reaches, and its role as a wing, the rear rotor in a low-voltage parts. This "suction effect" effective in around the rotor speed multiplied. Conventional wind turbine rotor can only be effective use of wind around 60 percent.
