: NOTE: This technology is a non-credited spin-off of Directory:Enviro Energies, Mag-Wind technology, who filed for a patent in China, only to have the patent not awarded, following the by Chinese government making this technology announcement.

The "MagLev generator" is said to be the world’s first (There was an error working with the wiki: Code[1]) permanent magnetic levitation wind power generator. Magnetic levitation is an important new development to reduce stress from the mechanical load on the wind turbine.

It is being regarded as a key breakthrough in the evolution of global wind power technology, boosting generation capacity by as much as 20% over traditional wind turbines, and dropping operational costs by as much as 50%.

How it Works

On July 23, 2006, the following by Jeremy Faludi was published in WorldChanging:

: "The magnetic levitation that they use is between the rotating shaft and the fixed base of the machine, basically taking the place of ball bearings. Such magnetic bearings have been used for decades in smaller turbines and pumps by Ebara, Leybold, Seiko-Seiki, and others. However, they generally can't handle being bumped around much (the magnetic force isn't that strong), and they generally require actively controlled electromagnets (to keep the levitating magnets from crashing--play with some magnets for a minute or two and you'll see why). Making magnetic bearings beefy enough to handle the loads a wind turbine would put on them is hard, and would use prohibitive amounts of power just keeping the electromagnets running strongly enough. However, the Worldwatch article says the new Chinese device uses "full-permanent" magnets, meaning there are no electromagnets, only cleverly placed permanent ones, so it should use no power.

: "Unfortunately there's not a shred of additional technical information in the article, nor is there any to be found elsewhere online (if you have any, please leave a comment!), so we can only speculate what their solution was. A little research made me conclude (and this is also suggested by a couple highly knowledgeable Treehugger readers who left comments) that they're probably using Halbach arrays in a system like the Inductrack invented at Lawrence Livermore Labs several years ago. Any permanent magnet system would doubtless need lots of Neodymium ("rare earth") magnets, which may have questionable sustainability when mined in large amounts, but as it happens China is rich in that element--in fact, points out that China owns 90% of the world's market of rare earth magnets."


The new wind power technology was the result of collaboration between Guangzhou Energy Research Institute, under China’s Academy of Sciences, and Guangzhou Zhongke Hengyuan Energy Science & Technology Co., Ltd.

Guokun Li is chief of Zhongke Energy and lead developer on the project.

Stage of Development

The Maglev generator was unveiled at the Wind Power Asia Exhibition, June 28, 2006 in Beijing.


The MagLev generator is expected to boost wind energy generating capacity by as much as 20% over traditional wind turbines. According to the technology's chief scientist, the generator can dramatically lower operational expenses of wind farms -- by as much as 50%.

Guokun Li anticipated the overall cost will be under 0.4 yuan ($US 5 cents) per killowatt.

The low wind speed capability is estimated to add an additional 1,000 hours of operation annually to wind power plants in areas with an average wind speed of 3 m/s.


The technology is expected to create new opportunities in low-wind-speed areas, with starting speeds as low as 1.5 meters per second (m/s), and cut-in speeds of 3 m/s.

China to mass produce maglev wind power generators - A Chinese company has invested 400 million yuan in building the world's largest production base for magnetic levitation (maglev) wind power generators capable of harnessing low wind speed. The base will produce a series of maglev wind power generators with capacities ranging from 400 to 5,000 watts in the first half of 2008. (Xinhua, China Nov 5, 2007)

Colossal Magnetic Levitation Wind Turbine Proposed - MagLev Wind Turbine Technologies claims that it can deliver clean power for less than one cent per kilowatt hour using a magnetically levitated wind turbine that can generate one gigawatt of power, by reducing frictional losses. A single huge turbine would require only a fraction of the land space of conventional turbines. (TreeHugger Jul. 27, 2007)

NEC Review

Not New

On July 17, 2006, New Energy Congress member, Congress:Member:Troy Helming, CEO of Directory:Krystal Planet, wrote:

The concept is sound, but not new. See (we are one of their 5 worldwide distributors, 1st installation went in last month in Toronto, 2nd one going up this week in Dallas).
