Olympic Games 2016

The Solar Tower for the 2016 Olympic Games - Rio de Janeiro
The challenge is to design a vertical structure on the island of Cotonduba that will become both a benchmark symbol and an observation tower to welcome the newcomers in Rio.
Designed by RAFA firm headquartered in Zurich, Switzerland, the proposed construction is called "Solar City Tower". This structure has the potential to generate enough energy not only for the Olympic city, but also for parts of the city of Rio.
Rafas design stores solar energy during the day. The surplus energy produced is used to pump sea water higher up the tower to finally give the effect of an outside waterfall. When the water finally hits the ground again, the energy of the pumped water will be reused with the help of turbines which are designed to produce energy during the night.
These characteristics give the epithet tower generator the opportunity to become a continuation of some of the resolutions made during the Earth Summit United Nations in 1992 that took place in Rio. Besides this, it will also to promote the use of natural resources and energy amongst the people.

The tower has an amphitheater, an auditorium, a cafeteria and shops accessible on the ground floor, where you can take an elevator that leads to various observatories. Besides this the tower has a retractable platform for the practice of bungee.
At the top of the tower, it will be possible to appreciate the scenery around the island.
