this was my design for a installation used during an artistic event called 400km [http://www.gdansk2016.eu/400km/]. The marry poppins I is a umbrella wind turbine. Its purpose was to generate electricity using wind that would power bike lamps placed inside the umbrellas and attract people

marry poppins I

This is a wind powered art instalation that was supposed to autonomously produce light at night to atract people. Finally the wind was to low to propel the bike dynamo installed but still the opening and closing movement of the umbrella did the job..
