Solar City Tower, to be built with the 2016 Olympics in Rio de Janeiro.
This vertical structure will be built in Cotonduba Island, in front of Rio, in conjunction with the Olympics 2016, that is taking place in Brazil. The building is both an observation Tower and a welcome sign for the visitors arriving by air and by Sea at Rio de Janeiro.
Designed by Zurique firm, RAAFA, Solar City Tower  features an artificial waterfall designed to generate clean, renewable energy: during the day the solar panels capture the energy needed to pump the sea water at the top, that is then conveyed through the turbines and produce the power to feed the system at night.
