This do-it-yourself wind engine brings together the local neighbourhood as well as social and/or ecological purposes in multiple ways. Green energy-sharing, community-building, education and qualification including explicitly all social groups are the project's main aims. It is located at the former airport Berlin-Tempelhof where several self-organized projects are founded near the street Oderstraße. The local non-profit organisations 'KitRad e.V.' and 'Taschengeldfirma e.V.' cooperate with the Technical University of Berlin and others in order to make the wind engine work. Both, the promotion of ecological but also social sustainablity, in connection with the small-level energy supply for these local projects are further goals of 'Windrad THF'.
