Technical Description
The invention captures atmospheric humidity using a sustainable, highly porous polysaccharides composite material that releases clean liquid water under nominal heating. Fabricated from low-cost agricultural by-products grafted into a hydrophilic polymer hydrogel matrix, the system incorporates solar-absorbing interfaces for thermal desorption and alternative mechanical or optical release mechanisms to function efficiently across diverse geographic and weather environments.
