1. A system for generating water from air comprising:
a hygroscopic material to capture water vapor from air during a loading operational mode, and release water vapor to a working fluid during an unloading operational mode;
a condenser configured to condense water vapor released in the working fluid to produce liquid water during the unloading operational mode; and
a controller configured to:
operate the system between the loading operational mode and the unloading operational mode based on a condition of the hygroscopic material, the condition of the hygroscopic material being a weeping, swelling or instability condition of the hygroscopic material; and,
set a system operational limit before an onset of weeping, swelling or other unstable condition.
 
15. A method for generating water from air comprising:
flowing air in a process flow path including a hygroscopic material to capture water vapor from air during a loading operational mode;
transitioning, via a controller, between the loading operational mode and an unloading operational mode based on a condition of the hygroscopic material, the condition of the hygroscopic material being a weeping, swelling or instability condition of the hygroscopic material;
setting, via the controller, a system operational limit before an onset of weeping, swelling or other unstable condition;
absorbing, by the hygroscopic material, thermal energy to release water vapor to a working fluid during the unloading operational mode; and,
condensing, via a condenser, water vapor in the working fluid to produce liquid water during the unloading operational mode.
