MIT has developed a new water harvester that can extract drinkable water from the air, potentially providing enough water for multiple people. The device features vertical fins coated with a specialized zeolite material, allowing for maximum water adsorption. After saturation, the copper sheets are heated to release the water, with the potential to produce up to 1.3 liters of water per day per liter of coating used. While other water harvesters exist, this design stands out for its efficiency and ability to work consistently throughout the day. However, the system requires energy to release the water, but can utilize waste energy sources.
