In arid climates, the atmosphere is a source of water, but its extraction is energy-prohibitive.
Many countries have arid climates in significant parts of their territory, which severely inhibits their land development and creates harsh humanitarian conditions. Atmospheric water harvesting (AWH) technology, which extracts moisture from ambient air to generate fresh water, is a promising strategy to realize decentralized water production in the arid areas and in regions where large-scale installations are impractical by economic or security reasons. However, existing sorption-based AWE prototypes exhibit prohibitively high energy consumption, hindering the technology deployment. Can we reduce the prohibitively high energy consumption of traditional sorption-based atmospheric water harvesting techniques to make decentralized water production economically feasible? In this innovative new approach, I have utilized vibrational mechanical actuation to extract water from moisture-harvesting materials to reduce the energy requirements and make the technology economically feasible for adoption on a large scale. The new method offers a 45-fold reduction of the energy needed to extract the same mass of water as the evaporation technique. The efficiency is not bound by the thermodynamic limit for the conventional desorption process, offering promise for further improvements.
