Image: AI-generated representation of a wood-based sponge that pulls water from air as dry as 15% humidity Water vapour is present almost everywhere, even in places where rivers, lakes and groundwater are scarce. The challenge has always been turning that invisible moisture into usable freshwater efficiently enough to make atmospheric water harvesting practical. Now, researchers … Read more

Meet Aniket Sarkar: The 13-year-old 3M Young Scientist who built a low-cost system to capture water from dry air for farmers

PC: 3M Young Scientist Lab Dry air is not completely without water. There is moisture suspended in the atmosphere even when rainfall is scarce, and 13-year-old Aniket Sarkar wanted to find out whether some of it could be recovered for agriculture. His idea led to a low-cost atmospheric water capture system built with ordinary materials, … Read more
