Eco-Thinker

Planned for the northern coast of Chile, this entry into the 2008 Evolo Skycsraper Competition is capable of producing clean water from the Chilean winds. The elegant looking 400 meter tall coiling tower collects the moisture from the unique coastal fog known locally as “Camanchaca“. The water molecules are trapped, then funneled downward into a basement area where trace minerals are filtered through a reverse osmosis system, which given the proper amount of filtration membranes reverse osmosis can filter out used pharmaceutical drugs and even fluorides. The clean water can then be distributed to support expansion of agricultural activity along the coast for the port city of Huasco. Designers Alberto Fernández and Susana Ortega have predicted that the spiraling pillars will gather a minimum 20,000 liters (283 gallons) of water per day to a maximum of 200,000 liters/day.
