  • Low-gravity water capture device
    Patent number: 11213779
    Abstract: An apparatus to separate water droplets from an air stream includes an elongated tube having a first end and a second end. The elongated tube includes an opening at a first end of the elongated tube, the opening may be positioned to accept the air stream. A reservoir is positioned at a second end of the elongated tube. A helix structure is positioned within the elongated tube. The helix structure includes an upper surface, a lower surface arranged opposite the upper surface, an outer edge, and a variable pitch along a length of the elongated tube. The variable pitch may provide a variable interior angle between an inner wall of the elongated tube and the upper surface of the helix structure.
