fog harvesting

Fog Tower - Designed by Fernández and Susana Ortega

In the mornings I walk past lamposts dripping with dew that has condensed overnight and wonder if I lived somewhere drier than Wellington if it would be worth catching that water.
It turns out it is worth it in some places.

The Ortegas designed this for the eVolvo skyscraper competition to collect the Camanchaca, a type of dense cloud that flows on the coast of Chile. The fog is caught in the fine plastic mesh skin of the tower to spiral down the helix and into collecting tanks.
