Harvesting water from air is a promising strategy for fresh-water production, and it is particularly desirable for areas that lack direct access to clean water. While high-concentration liquid sorbent is well-known for high sorption, it has not been widely used for atmospheric water collection, being primarily limited by the difficulty in desorption. Interfacial solar heating based on a salt-resistant GO-based aerogel is now shown to enable a high-concentration liquid sorbent (CaCl2 50 wt % solution) based atmospheric water generator. Fresh water (2.89 kg m(-2) day(-1)) can be produced at about 70 % relative humidity, with only solar energy input and energy efficiency of desorption as high as 66.9 %. This low-cost and effective approach provides an attractive pathway to extract water from air, to relieve the thirst of arid, land-locked, and other areas where fresh water is scarce.
