Research in Chile could help to provide drinking water for some of the world's most arid places.

Fog harvesting is a relatively simple process. Mesh panels are hung between poles, and as moisture-laden clouds pass through the mesh, water droplets form and are channelled into pipes and storage tan

It's not a one-stop solution to water shortages, but it could help supplement other harvesting and conservation methods.

In a nutshell Scientists discovered that fog collection could provide up to 10 liters of water per square meter daily in areas surrounding Alto Hospicio, Chile, enough to help supply the city’s 10,000 informal settlement residents who currently rely on water truck deliveries.
