Siemens unveils “world’s longest” wind turbine blade

And they say size doesn't matter.  Well i'm impressed !

Siemens has unveiled the first batch of its new 75 metre-long wind turbine rotor blades, which it claims are the “world’s longest”.

The B75 Quantum rotor blades will be installed on the second prototype of Siemens' 6 MW offshore wind turbine, which will be erected in later this year in Denmark's Østerild Test Station.

The launch of the new blade signifies a 200-fold growth in the energy capture area and the turbine capacity of Siemens’ turbine products over the last 30 years. The company’s first commercial wind turbine had a capacity of 30 kW and 5 metre-long rotor blades, for a 10 metre rotor diameter, while the latest turbine has a 6MW capacity and 75 metre long rotor blades for a rotor diameter of 154 metres.
