Fog Harvesting: Making Water From Air
necessity is the mother of invention: when people are faced with a problem or need, they become creative and find new ways to solve it
In Kenya’s mountains, people have found a way to get water from the air. It’s called fog harvesting.
Jacob Murungi and his wife collect water from trees using plastic sheets. He explains that they attach plastic to trees to collect condensed water. “At night when the mist comes, water forms on the tree. Then it rolls down the trunk, onto the plastic and into this container.” They use this water for drinking, washing, and for their animals.
Around the world, many places don’t have enough water. Climate change is making it even harder to find. Fog harvesting is now being done in Morocco, Chile, Yemen, Ethiopia, and parts of Southeast Asia. Some use large nets to capture the water from the air.
New technology is also being used to make water from air in places where there is no fog. They use fans to bring in wet air, cool it down, and make water.
These new and old ways of making water from air show that necessity is the mother of invention.
1. During a camping trip, I forgot my cooking pot, so I cooked my soup inside a cleaned-out can; necessity is the mother of invention.
2. When my shoelace broke during a hike, I used a vine from a nearby tree to tie my shoe together; necessity is the mother of invention.
3. When my bicycle got a flat tire, I didn’t have a repair kit, so I used duct tape to fix it; necessity is the mother of invention.
