MOFs, hygroscopic hydrogels, carbon sorbents, and salt-loaded porous matrices can now capture substantial amounts of water from air. Several practical challenges remain, however: Many high-performance sorbents are made f

Metrics such as Unit Power Consumption (kWh/L), Specific Energy Consumption, Water Harvesting Rate, and Specific Water Production per mass of sorbent have beco

However, real-world deployment also depends on another practical factor:
