Fog → Drinking Water: The Simple Tech Bringing Potable Water to Arid Regions
Manage episode 507731246 series 3568279
These giant meshes turn fog into drinking water—no pumps, no power. It’s CloudFisher, a system developed by the German NGO WasserStiftung that captures airborne moisture with technical plastic nets stretched into the wind.
How it works
Zero energy: wind + fog, no electricity required
Durable & recyclable: engineered to resist winds up to 120 km/h
Potable by design: collected water is filtered to WHO standards, then routed to public fountains or cisterns
Why it matters
In Morocco’s Anti-Atlas, a 1,674 m² installation produces ~36,800 L/day for 1,300 people across 5 villages
Each m² of net can harvest up to 22 L/day in foggy conditions
It taps the sky—not aquifers—so it doesn’t disrupt local water cycles
Old wisdom, modern scale
Inspired by centuries-old Andean and Amazigh practices of dew and fog collection—now upgraded with modern materials and deployment at community scale. Already active in 5+ countries.
If you’re building in climate & water:
What would it take to pilot this in your region?
Could schools, clinics, or shelters be first beneficiaries?
Pairing with storage, UV, or remote monitoring—who’s in?
