Tom Durning doubts that this is for real – but it sure is amazing:

“Solar City Tower,” built atop the island of Cotonduba, will be the welcome symbol to the 2016 Olympic Games in Rio de Janeiro.

.

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 stimulates turbines that produce energy during the night.

It will also hold the Olympic flame.

.

At the summit is an observation point to appreciate the scenery of the land and ocean, as well as the water fall.  It also has a retractable platform for the practice of bungee jumping.
