Cicada’s Garden
Where energy has no end.
In this garden there is artificial life and some of its “specimens” interact with the visitors. Throughout the garden visitors will find “flowers” that react to their presence and “flowers” that accumulate energy during the day. “Technological bugs” can also be found. Pay attention to the sound of the Cicada’s. Does she exist?
The entire energy in this garden comes from the sun, the wind and even from those who visits it. |

Central System for supplying Renewable Energy
The electrical energy used in the garden is provided by this central system.
The system uses two sources of renewable energy: Photovoltaic panels capture the sun’s energy and an Aeolian generator utilizes the winds energy. The electrical energy produced is stored in a pack of batteries for later use. |

Sunflower
Why does it follow the sun?
Sunflowers follow the sunlight, making energy capture more efficient.
The leaves house
solar photovoltaic cells, which use the sunlight to produce electricity. This energy is
stored in a pack of batteries during the daytime. At night time this energy is released to
illuminate the sunflower. Two light sensors guide the “plant” towards the sun. Every
four minutes the sunflower moves one degree. Put your hand in front of the solar cells.

Cascading Energy
1, 2, 3… start pedalling. How many flowers can you spin?
When one or more people pedal kinetic energy is given to the system. This energy is used to shoot water from the lake to the flowers. The stream of water causes the top flower to rotate. The rotation movement generates a centrifugal force that makes the flower open. The flow of the water from the stream accompanied by the falling water from different levels causes the flowers on the terraces to spin creating cascading energy (potential and kinetics energy).

Chameleon Competition
Start pedalling, don´t stop. Who wins?
When you pedal kinetic energy is converted into electric energy by the dynamos connected to the bicycles. The electric energy is then transformed back to kinetic energy, causing the bicephalous chameleon to move. The movement of the chameleon is powered by an electric motor, which in turn moves the chameleon from side to side (electric potential difference). The bicycle that produces the most energy wins.
