Born from unique environmental conditions, GEOtube is a new kind of urban sculptural tower designed by California-based Faulders Studio. Gravity-sprayed with adjacent Persion Gulf waters, its building skin is entirely grown rather than constructed; is in continual formation rather than fully completed; and is created locally rather than imported. The world’s highest salinity for oceanic water is found in the Persian Gulf (and the Red Sea) – local salt water is supplied to GEOtube via a new 4.62 km buried pipeline and misted onto the tower’s exposed mesh. 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 for wildlife that thrives is this environment, and an accessible surface for the harvesting of crystal salt.
