The Supper-powered Magnetic Wind Turbine

In recent years, renewable energy produced from wind has received much attention and support. Wind energy is, however, often criticized for its low output and lack of reliability. Happily, a super-power wind turbine is now on offer. This may just be what the renewable energy industry needs. The Maglev wind turbine, which was first unveiled at a world exhibition, is expected to take wind power technology to the next level. The technology, which employs magnetic levitation, is an extremely efficient system for wind energy.

How does this technology work? The vertically oriented blades of the wind turbine are suspended in the air above the base of the machine, replacing the need for ball bearings. The turbine uses “full-permanent” magnets, not electromagnets. As a result, it does not require electricity to run. The full-permanent magnet system employs neodymium (”rare earth”) magnets and there is no energy loss through friction. This also helps reduce maintenance costs and increases the lifespan of the generator.

   

Maglev wind turbines have several advantages over conventional wind turbines. For instance, they are able to use winds with starting speeds as low as 1.5 meters per second (m/s). Also, they could operate in winds exceeding 40 m/s. Currently, the largest conventional wind turbines in the world produce only five megawatts of power. However, one large Maglev wind turbine could generate one gigawatt of clean power—enough to supply energy to 750,000 homes! It would also increase generation capacity by 20% over conventional wind turbines, and decrease operational costs by 50%. Importantly, the Maglev wind turbines are operational for about 500 years!
