US scientists turn dry air into drinking water with 5 times more efficiency | Even in desert-like conditions, the fins were saturated with water in about an hour.
Using a commercially available coating material and copper, US researchers have designed a water harvester that works even in desert-like conditions.
The US-based researchers suggest that for the technology to be deployed in the real world, the setup needs to be small and compact and ideally connected to a device that produces heat as a by-product. Extrapolating these 24 collection-release cycles, the researchers found that the device could collect up to 1.3 liters of water per day when used in an environment with 30 percent relative humidity. The researchers suggest that the device be integrated into existing infrastructure, such as buildings or vehicles that produce waste heat, to develop a cost-effective solution for harvesting fresh water.
