The Siemens B57 blades bring forth a new approach to wind turbine design. Wind turbines have the potential to be extremely powerful, and moreover extremely relevant insofar as green energy production goes. Entire cities may run on the technology if enough force is produced, and these Danish implements promise to accomplish just that.
The B57 blades are made of epoxy resin and balsa wood. Its complex configuration deliberately excludes joints and bolts so as to make the wings lighter. At 75 meters long the propellers can span approximately 18,600 square meters at 180 MPH. These considerable measurements will advance the wind turbine industry in its entirety, and if all goes according to plan, they may help to power 1.8 million abodes by the year 2017.
