Smart spongy device captures water from thin air

Science Daily Wednesday, 7 May 2025 ()
Engineers have invented a sponge-like device that captures water from thin air and then releases it in a cup using the sun's energy, even in low humidity where other technologies such as fog harvesting and radiative cooling have struggled. The water-from-air device remained effective across a broad range of humidity levels (30 -- 90%) and temperatures (5 -- 55 degrees Celsius).
