Abstract
Sorption-based atmospheric water harvesting (SAWH) offers a promising solution to global water scarcity. However, practical implementation is limited by discontinuities in the mass transfer process inside sorbents. This perspective reviews current SAWH technologies and introduces a new concept, mass transfer of SAWH (MT-SAWH), which ensures continuous water collection by facilitating the movement of water molecules within a fixed sorbent bed. We discuss design principles and the potential for using renewable energy to maintain a stable water supply. Our goal is to highlight the future potential of SAWH and encourage the development of efficient water harvesting systems.
