Systems and methods for generating water from air

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 binder to bind particles of the hygroscopic material so as to form a rigid self-supporting hygroscopic composite;
• 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.
