As far back as 2,000 years ago, desert villages and other rain-starved communities around the world may have started harvesting fog that collected as water and dripped from trees, said Robert Schemenauer, executive director of FogQuest, a Canadian nonprofit organization that helps communities set up simple collection devices.
Serious work on collecting fog started about a hundred years ago. Since then, fog catchers have been used successfully—though on a small scale—all over the world.
