Man that’s high.
Offshore wind power specialist Vestas has revealed plans to build the largest dedicated offshore wind turbine in the world.
The proposed V164 would have a 7.0 MW capacity, twice that of its predecessor, the 3.0 MW V112.
The awesome 164 meter (538 ft) diameter rotor would eclipse the size of the current titleholder, the prototype G10X installed by Gamesa in Spain in 2009 which has a diameter of 128 m (420 ft).
