The wind turbine factory Maglev (magnetic levitation), located in China, has begun to produce in series. There will be turbines with capacities of 400 to 5000 watts.
But what is a Maglev wind turbine?
Improves efficiency by using magnets to reduce friction, this means that the turbines can start spinning winds of only 1.5 m / s and start producing energy at 3 m / s. The leader of the development of wind turbines said that the operating costs of wind power can be reduced by half, for a total cost of 5 cents per kWh kilowatt hours.
For developing countries like China, this technology can be crucial to bring wind power to where it is not used or carriage is very expensive. For the first world countries they are also very practical because they will be much cheaper and the idea of a wind turbine on a house is much more feasible.
The company says it can also supply electricity to its roads using wind turbines, since the only thing they need is wind generated by passing vehicles.
The boom of wind energy in China is unbelievable. They have the fifth largest installed capacity of renewable energy and are willing to achieve the goal of 5 gigawatts by 2010.
Although magnets have been used before in a turbine for pumps and to reduce friction, they have generally been electro magnets, which require additional power to operate. The technology used in the turbines is a secret, for intellectual property issues, but the company has indicated that the system is based solely on magnets, so you do not need extra energy.
The company Zhongke Hengyuan Energy Technology Co Ltd, the creator of these wind turbines, has invested 400 million yens, and expect a gain of 1.6 billion annually.
This technology is just starting, but it looks very promising, and can make wind power accessible to households. We will keep an eye on developments.
