It will be both a observation Tower, and a welcome sign for the visitors arriving by air and by sea at Rio de Janeiro , where the Olympic Games 2016 will take place. It will be seen by the game visitors and participants as they arrive by air and by water. The tower captures solar energy. It will supply energy for all of the Olympic city, as well as also for part of Rio. It pumps up water from the ocean to create what appears like a water fall and this fall stimulate will turbines that will produce energy during the night. It will also hold the Olympic flame. The Solar City Tower will be the point of reference for the 2016 Olympic Games in Rio de Janeiro .

The project is from Zurique, and utilizes solar energy during the day with its solo power panels, to pump the sea water as seen in the model. The movement of the water will be also utilized to turn the turbines and produce the power to work the system at night time.

In the Solo City Tower is the Cafe amphitheater, auditorium, a cafeteria and boutiques, shops etc. The lifts will take the visitors to the top, where the view will be fantastic, and bungee jumping will have a special retractable platform.
