Startup companies from Spain said that, despite the beauty of conventional wind turbines, there is a cheaper way of producing electricity from wind . Their project is called Vortex Bladeless, and at first glance it may seem that the wind turbines, which are used here, look like regular posts, buried in the ground.

These poles-wind turbine is also used to generate electricity. However, the wind is not used to spin the blades. The blades are not at all. Instead, the wind is used to generate vibrations windmill. Usually, civil engineers when designing a variety of high-rise buildings are trying to find ways to avoid the impact of these forces on the structure. However, the creators of the turbines Vortex, in contrast, have found useful application of this feature fluctuations.

As a rule, the structure can be optimized to vibrate only at certain frequencies, at a certain wind speed, but Vortex say "setup" for any type of turbine and wind during service is possible through the use of magnets. When the structure starts to vibrate at the base of the turbine generator converts the mechanical motion into electricity.

What is the advantage of new turbines in comparison with traditional windmills? The Vortex claim that the cost of energy produced by their turbines will eventually be about 40 percent lower compared to the cost of energy produced by wind generators are now common. The fact is that a huge part of the economy depends on the cost of maintenance of wind turbines. Since turbine Vortex not have moving parts and actuators, then: firstly, they can last for much longer; Second, do not require periodical maintenance. In addition, the simple design and construction implies a lower price during the construction and installation. The cost is reduced by about half compared to conventional wind turbines (where a large part of the cost falls on the huge blades).

In an interview with Wired Spanish company told that their turbine is extracted about 30 percent less energy compared to conventional. The company Please note that due to the design of their turbines in the same area can be set much more of windmills. Bonus - without paddles turbines operate noiselessly.

The company is currently working on several sizes of turbines. "Mini-version" is a turbine height of about 12 meters. For commercial use, it will be ready next year. Larger, industrial version of the turbines is scheduled to start producing in 2018.
