A Lima, Peru neighborhood was struggling to get water without plumbing until the German nonprofit, Alimon, came up with an innovative way to provide the area with fresh water. It involves setting up massive water-catching nets on a hillside above the neighborhood, Good reports.
Noticing that the city gets a lot of fog, Alimon set up nets in the hills above the neighborhood that trap that moisture and funnel it into aqueducts and reservoirs where it can be used for drinking or farming. The large nets cost the equivalent of $800 and can yield as many as 60 liters in a night.
If this idea sort of boggles your mind (it took us a few minutes to figure it out), we suggest you check out the "Green Desert Project" on Alimon's Web site for diagrams of how the water-catching contraptions work.
