Small, adsorbent ‘fins’ collect humidity rath - EurekAlert
Clean, safe water is a limited resource and access to it depends on local bodies of water. But even dry regions have some water vapor in the air. To harvest small amounts of humidity, researchers in ACS Energy Letters have developed a compact device with absorbent-coated fins that first trap moisture and then generate potable water when heated. They say the prototype could help meet growing demands for water, especially in arid locations.
