Østerild, Denmark is currently the testing ground for giant offshore wind turbine with world’s longest rotor blades each of which measures 75 m in length. Just to provide you with a better idea of the measurement, its mandatory to inform you that each of the blades measures almost as wide as wingspan of an airbus A380. When in motion, each of the rotors covers 18,600 square meters; size of two and a half soccer fields.
The blade’s tip can race at an amazing speed of 290 km/hr. The blades are made of glass fiber-reinforced epoxy resin and balsa wood; making them 20% lighter than commonly manufactured blades.
These robust wind turbines generate up to six megawatts of power which is enough to light up 6,000 households. The gigantic turbines are set to cover British coasts in the coming time as well.
