Spontaneous water oozing of a soft drain bed via energy-free atmospheric water harvesting.

ABSTRACT: Atmospheric water harvesting has emerged as an efficient strategy for addressing the global challenge of freshwater scarcity. However, the in being energy-consuming water-collecting process has obstructed its practicality. In this work, a soft drain bed, which was composed of hydrophilic cloth and hygroscopic gel, has been demonstrated to capture atmospheric water effectively, followed by converting it into liquid water spontaneously and sustainably, under all-weather humidity conditions. Under the optimal working condition of 30°C with a relative humidity level of 75%, the bed can provide a spontaneous water oozing ability of 1.25 g _{(liquid water)}/hour within the 8 h of working time. More importantly, after 5 working cycles, 80% of the oozing ability can be reserved, suggesting
