Lens increase in wind turbine energy output

Prof. Yuji Ohya Kyushu University for applied research institute for mechanics (Miriam), has worked with a team to improve the efficiency of wind turbines. The power has been improved by a factor of 2-5 times in different experiments, while also reducing noise turbine.

The operation is to create an area of ​​low pressure behind the turbine, which basically sucks the wind through the turbine, increasing the effective speed of the wind. As wind energy is proportional to the cube of wind speed, the lens changes as the dynamic flow of the wind increasing the potenza.Karl Burkart of Mother Nature Network, guides us through the implications.

The U.S. is ranked at 3 rd place in the world for potential wind resources.
Using only 20% of this potential change and turbines with a lens, could generate enough energy to meet 100% of current U.S. electricity production.

Researchers at the Miriam have anticipated the best use of wind turbines offshore, where winds tend to be more consistent and higher speeds. In an effort to promote offshore wind applications, have also designed a floating platform hexagonal could be used in combination with wind lens turbine technology.
