Abstract

An atmospheric water harvesting material includes a deliquescent salt, a photothermal agent, and a polymeric hydrogel matrix containing the deliquescent salt and photothermal agent.

Claims

exact text as granted — not AI-modified
1 - 14 . (canceled) 
     
     
         15 . An atmospheric water harvesting device, comprising:
 a condensation chamber having a light-admitting upper surface and a water outlet; and   an atmospheric water harvesting chamber, arranged below the condensation chamber, containing an atmospheric water harvesting material and having a bottom surface with an opening to accept ambient air and an upper surface having an opening to allow atmospheric water captured from the ambient air by the atmospheric water harvesting material to pass into the condensation chamber due to heat generated from solar energy impinging on the light-admitting upper surface of the condensation chamber.   
     
     
         16 . The atmospheric water harvesting device of  claim 15 , wherein the atmospheric water harvesting chamber includes a cylinder having an outer surface on which the atmospheric water harvesting material is arranged. 
     
     
         17 . The atmospheric water harvesting device of  claim 16 , further comprising:
 a motor coupled to the cylindrical water harvesting chamber and configured to rotate the cylindrical water harvesting chamber.   
     
     
         18 . The atmospheric water harvesting device of  claim 15 , wherein the condensation chamber further comprises:
 a water collector arranged to collect water condensed in the condensation chamber and to direct the collected water to the water outlet.   
     
     
         19 . The atmospheric water harvesting device of  claim 15 , wherein a portion of the light-admitting upper surface of the condensation chamber is covered by a non-transparent material. 
     
     
         20 . The atmospheric water harvesting device of  claim 15 , wherein the atmospheric water harvesting material comprises:
 a deliquescent salt;   a photothermal agent; and   a polymeric hydrogel matrix containing the deliquescent salt and photothermal agent.   
     
     
         21 - 25 . (canceled)
