The Blue Crane is a relic of past times. It is a well-known landmark of the port industry which gave the city of Offenbach its identity in the 20th century.
The project Blaue Sonne (Blue Sun) investigates the possibility of reinventing a new symbolism for the blue crane by converting the old obsolete industrial heritage in a new infrastructure collecting energy and providing a point of connection and gathering for the public space surrounding it. In this way the Blaue Sonne becomes a new landmark for a new culture of living in harmony with nature and its resources.
The five public platforms climbing around the crane are reinventing a new type of public space, spiralling and ascending the crane to reach the final point where the sun sets on Offenbach. The same Sun is transferring his energy to a large circular photovoltaic panel which redistributes the energy, used for connecting mobile devices and providing electricity points for events organised on and around the crane.
