Fog Water Collection in Chile

The video discusses the global issue of water scarcity, focusing on Chile's Atacama Desert, one of the driest places on Earth. It explores the potential of fog as a source of fresh water, naturally desalinated by the sun. Researchers at MIT are developing technology to collect water droplets from fog using specialized meshes. This technology has improved fog collection efficiency by 500%. In northern Chile, fog water is being used for agriculture, transforming former fishermen into farmers. The video highlights the potential of fog water to meet drinking water needs if just a small percentage is harvested.
