ANTARIS treetop wind turbine

Wolfgang Frey, an architect from Freiburg, enters the wind power debate with treetop wind turbines. He installed an ANTARIS 3.5 kW small wind turbine on a Douglas-fir that was 30 metres high as a pilot plant in Freiamt in the district of Emmendingen. A legal loophole in the rules on authorisation makes this possible.
