The self-sustaining tower for the 2016 Olympic Games is designed to create renewable energy for use in the Olympic Village as well as the city of Rio. A large solar power plant generates energy during the day. Any excess power not used during the day is utilized to pump seawater into a storage tank within the tower. At night, the water is released to power turbines, which will provide nighttime power for the city. On special occasions water is pumped out to create a waterfall over the edges of the building, which RAFAA says will be, “a symbol for the forces of nature.” Info on the size of the solar and pumped water storage system is not available yet.
Access to the eco tower is gained through an urban plaza and amphitheater 60 meters above sea level, which can be used for social gatherings. On the ocean side of the 105 meter tower (behind the waterfall) is a cafeteria and shop. An elevator takes visitors up to the top floor where an observation deck offers 360 views of the ocean and city. At level 90.5, a bungee platform is available for adventurous visitors.
