China Makes Huge Breakthrough in Wind Power Technology by Zijun Li:
Chinese developers unveiled the world’s first full-permanent magnetic levitation (Maglev) wind power generator at the Wind Power Asia Exhibition 2006 held June 28 in Beijing, according to Xinhua News.
…
The Maglev generator is expected to boost wind energy generating capacity by as much as 20 percent over traditional wind turbines. This would effectively cut the operational expenses of wind farms by up to half, keeping the overall cost of wind power under 0.4 yuan (5 cents US), according to Guokun Li, the chief scientific developer of the new technology. Further, the Maglev is able to utilize winds with starting speeds as low as 1.5 meters per second (m/s), and cut-in speeds of 3 m/s, the chief of Zhongke Energy was quoted as saying at the exhibition. When compared with the operational hours of existing wind turbines, the new technology will add an additional 1,000 hours of operation annually to wind power plants in areas with an average wind speed of 3 m/s.

I heard that they are having major difficulties making it stable! THe power boosts could affect any electrical equipment and even for this date they haven t made a huge step forward. I saw this prototype on the Hamburg Tech Show in July 08 so, nothing special, but still a breakthrough.
The ability to deploy the turbine high in the air without expensive towers seems like a huge advantage (of course it will have to work in the practice which I imagine will be the most challenging part)…????
