CloudFisher is an innovative water harvesting system that collects fresh water from fog in arid regions. Developed by the German non-profit organization WaterFoundation, CloudFisher is designed to be a low-cost, sustainable solution for providing clean water to communities that lack access to traditional water sources. The system uses fine mesh nets to capture water droplets from fog, which then drip into storage tanks for use by local residents. CloudFisher has been deployed in regions such as Morocco and Chile, where it has made a significant impact on improving water security and supporting sustainable development.
