Clean, safe water is a limited resource and access to it depends on local bodies of water. Conventional water collection from thin air tends to be resource-intensive. However, researchers have developed a new method, as reported in ACS Energy Letters, involving compact devices with absorbent-coated fins that efficiently trap moisture and generate drinkable water when heated.
This innovative technology is especially promising for arid regions where humidity levels are low. The device’s water-adsorbent “fins,” made of copper foams coated with zeolite, quickly harvest water from the atmosphere. The prototype demonstrated the potential to produce up to 1.3 liters of potable water per day from air with 30% relative humidity.
These findings open up exciting possibilities for cost-effective water generation, particularly in dry areas where traditional methods may not be feasible. Additionally, low-tech solutions like solar energy innovations by pioneers like Maria Telkes offer sustainable alternatives for water collection and food preparation in regions facing water scarcity.
