The Solar City Tower is probably the most stunning piece of architecture I have seen in awhile. I mean, all you need to do is look at the gallery above to whole-heartedly agree with me. Taking form of a picturesque waterfall, I can't believe it was manmade (actually, of course I can).
Designed by RAFAA Architecture & Design for the 2016 Rio Olympics, the Solar City Tower will be a symbolic structure that strives to make the 2016 Olympics as sustainable as possible. Featuring a large solar system, it definitely provides a good starting point.
