Abstract
A system for water extraction from air is provided. The system includes a housing having a plurality of openings allowing an air flow to enter into an inner space defined by the housing. The system also includes a sponge disposed within the inner space defined by the housing. The sponge includes a water absorbing/adsorbing material for absorbing/adsorbing water vapor from the air flow. The system further includes a presser disposed above the sponge and configured to compress the sponge to discharge water from the sponge.
Claims9
A system for water extraction from air, comprising:
- a windmill comprising a plurality of rotatable blades configured to rotate about a horizontal axis and having surfaces that include a water absorbing/adsorbing material for absorbing/adsorbing water vapor from an air flow during rotation of the blades about the horizontal axis;
- a vertically oriented ring shell structure disposed coaxially around the blades and configured to allow air to flow axially in a horizontal direction into and out of the windmill and capture water droplets shed from the surfaces of the blades during rotation;
- and
- a water collector located under a bottom portion of the vertically oriented ring shell structure configured to collect water droplets received by the ring shell structure, the water collector being disposed below the horizontal axis about which the blades are configured to rotate.

A system for water extraction from air, comprising:
- a windmill comprising a plurality of rotatable blades configured to rotate about a horizontal axis and having surfaces that include a water absorbing/adsorbing material for absorbing/adsorbing water vapor from an air flow during rotation of the blades about the horizontal axis, wherein the water absorbing/adsorbing material includes a tertiary amine, a polyethylene glycol, or hydrophobic activated carbon;
- a vertically oriented ring shell structure disposed coaxially around the blades and configured to allow air to flow axially in a horizontal direction into and out of the ring shell structure and capture water droplets shed from the surfaces of the blades during rotation, the ring shell structure being configured to connect to a water collector at a radially outward-facing portion to collect water droplets received by the ring shell structure;
- and
- a water collector located at a bottom position of the ring shell structure for collecting water droplets received by the ring shell structure, the water collector being disposed below the horizontal axis about which the blades are configured to rotate.

- a vertically oriented ring shell structure disposed coaxially around the blades and configured to allow air to flow axially in a horizontal direction into and out of the windmill and capture water droplets shed from the surfaces of the blades during rotation;
- a power supply configured to supply power to drive the rotatable blades;
- one or more support structures configured to secure the ring shell structure in place around the rotatable blades;
- a water collector located under a bottom portion of the vertically oriented ring shell structure for collecting water droplets received by the vertically oriented ring shell structure, the water collector being disposed below the horizontal axis about which the blades are configured to rotate;
- and
- a water tank fluidly connected to the water collector by a conduit.
