Siemens to unleash new offshore wind-turbine blade

Engineering giant Siemens is preparing to unveil a new 75-metre long rotor blade for use in its future offshore wind turbines. Siemens is claiming that the rotor will have a swept area of 18,600 metres – almost the equivalent of two and a half football pitches.

This latest engineering move from Siemens come as wind-turbine manufacturers vie to come up with bigger and more efficient blades to produce greater electricity by sweeping over a larger surface area, while also being more cost-effective.
