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?
