In the distance is about 100km south of Auckland, New Zealand Waikaretu of a hill, a revolutionary new wind turbine being a two-year test run. The appearance of this wind turbine generator compared with the conventional wind turbine is completely different, its height is 17m, much like a huge object squatting on top of the hill, while the conventional wind turbine was a slender body, standing high on a hill.
This is put into operation the first commercial wind generator -enhanced diffusion body (DAWT: diffuseraugmentedwindturbine), if the developers achieved the expected results will lead to a significant reduction in the cost of wind power. In testing new wind turbine technology, but also test-proliferation body rings can cover new materials, high-strength steel fiber reinforced concrete. Such wind turbine, known locally as “concrete wind turbine.” In business, it is called Vortec7 type small wind turbine, because it has a 7m diameter of the rotor.
Wind turbine by the nearly 100 small-scale investors set up a private company-Vortec Energy Limited responsible for the design and construction, the company raised 3.5 million U.S. dollars developing the prototype. Vortec Energy Limited is currently being further raise about 700 million, plans to build two 20m rotor diameter of the unit. One of the new units will be in areas of high wind speed test, it is possible near Wellington in New Zealand, another in the average wind speed zone. South Australian Government has expressed great design interest and will accelerate in the near Adelaide Anzhuang average wind speed unit, because the state government that is a little wind and renewable energy, technological breakthroughs needed to drive from the dominant state lower average wind speed resource development.
Two new rotor diameter of 20m the unit successfully running, Vortec Energy Limited will consider the possibility of listing in the Nasdaq stock exchange. Vortec7 unit performance data show that the design of the rotor diameter of 20m to less than 0.031 U.S. dollars to / kWh price of Internet access, it will make wind power can compete with New Zealand’s existing power plants, power generation and other than the new, more competitive. If the Vortec-type function to such a price level of wind power, wind power generators development in that it will quickly become a powerful new force.
Vortec Energy Ltd. backing entrepreneurs RobinJohannink, he successfully ran a business, but also PacificLithium Corporation (lithium extracted from seawater, a company) backing. Mr. Johannink say Vortec technology is an international product, but the technology in New Zealand stock market gained recognition and attention is not too difficult in this market. So Vortec Energy Ltd is considering New York’s Nasdaq Stock Exchange, it is possible to achieve in 1999.
