Conceptualized by California-based architecture firm Faulders Studio, GEOtube is a new kind of urban sculptural tower proposed for Dubai that uses salt water to grow its own skin.
The building sucks up water from the Persian Gulf (the source of the world's saltiest ocean water) through a 3 mile (4.62 km) underground pipeline, and then sprays it over a mesh facade. As the water evaporates and salt deposits aggregate over time, the tower's appearance transforms from a transparent skin to a highly visible white solid plane. The result is a specialized habitat that provides an accessible surface to harvest salt.
