In the Atacama Desert, in Chile, it hasn’t rained for hundreds of years, but it does get plenty of fog. Poor communities here need freshwater to drink, as well as irrigate crops and aid with reforestation. So they’ve developed large mesh fog collectors. These hillside devices use a fine polypropylene mesh, which is highly efficient at capturing water-laden fog. Juan de Dios Rivera, from the Pontifical Catholic University, is a global expert and alongside Jacques Dumais, from the University of Adolfo Ibáñez, is developing large-scale systems that could supply whole communities and compete in price with sea water desalination. “We want to follow the development of wind power and develop the equivalent to a modern multi-megawatt wind turbine,” says Mr de Dios Rivera.
