Inspired by a spider’s web that naturally traps dewy droplets from mist, a volunteer engineer Peter Trautwein has set up CloudFisher, the world’s largest operational fog-harvesting project, which turns fog into drinking water in the driest parts of Morocco. The technology, which can harvest up to 36,000 liters of water for 800 people daily, has a life-changing impact in arid areas, where finding water can consume up to three hours a day.

The CloudFisher is essentially a giant net structured with tiny triangles, suspended vertically in the mountains, writes Design Boom. When the winds propel fog into the nets, water droplets are captured in the mesh; then they condense in a trough below and eventually flow into a reservoir that stores drinking water.

The initiative, which provides water at a lesser cost than tap water in the area, has been awarded the Momentum for Change Award from the United Nations Framework Convention on Climate Change, notes Curbed.
