Many towns have little rain. It is a challenge for people to get water. Scientists in Chile say harvesting water from fog could provide water for millions of people. The researchers studied how fog harvesting can collect water. Water from fog is collected on large mesh screens. Drops of fog water stick to the mesh. The water then drips into storage tanks below. This is a cheap and easy way of collecting water in dry areas.
The researchers tested fog harvesting in a desert town which gets 5 mm of rain a year. People there get their drinking water delivered by truck. A researcher said fog harvesting could change this. People will think more about the uses of fog water. She said it could be a "practical water resource". She said "water from the clouds" could protect cities during climate change. She added that fog harvesting could give cities access to clean water.
