The aim of this project is to ask how the classic concept of a landmark can be reconsidered. It is less about an expressive, iconic architectural form; rather, it is a return to content and actual, real challenges for the imminent post-oil-era. This project, standing in the tradition of “a building/city as a machine”, shall provide energy both to the city of Rio de Janeiro and its citizens while using natural resources. it's a project for 2016 olympic Games.
