On 21 November Thilo Wirth visited the Grevenbroich test site west of Cologne and took several photos of the damaged Agile Wind Power’s Vertical Sky 32.
The Swiss-built straight-blade VAWT lost one of its three rotor arms and blade Sunday 15 November. The prototype turbine was installed at the site in September and was still undergoing testing.
The H-configuration VAWT at Grevenbroich is 32 meters in diameter and each straight blade is 54 meters long, giving the machine 1,730 m² of swept area.
