The wind turbine tower is being installed at the Technical University of Berlin (HTW). In the end, the height of the turbine is 10 meters. When the "moving leg" falls into position in the end, there are some white pieces falling off, which is just snow...

Its design has been developed by students of the Civil Engineering department in cooperation with the department of Renewable Energy Systems. The “structural inspection-report” has already been successfully passed, which was the very condition in order to get the building permit.
