Abstract
A device for purifying water by solar power is described. The device has bottom and top sections, each being half-cylinders contacting one another along a flat edge to provide an elongated cylinder. The bottom section has an evacuated area with an optically transparent bottom surface that light can pass through to heat a liquid tray in the top section. A side-gutter directs water that condenses on an interior surface of the top section to an output port for collection.
Claims20
A device for purifying water by solar power, the device comprising:
- a bottom section and a top section, each being half-cylinders contacting one another along a respective flat edge to provide an elongated cylinder;
- the bottom section comprising a cover that defines the flat edge of the bottom section;
- a liquid tray that defines the flat edge of the top section, at least one side-gutter that directs water that condenses on an interior surface of the top section to an output port, the liquid tray further comprising an input port for adding water into the liquid tray an axil extending along a length of the elongated cylinder and parallel to the flat edge, the axil comprising a plurality of evaporation disks that are orientated perpendicular to the axil, the evaporation disks extending both into the water in the liquid tray and above the water in the liquid tray;
- a motor configured to rotate the axil.

- the bottom section comprising a cover that defines the flat edge of the bottom section;
- a liquid tray that defines the flat edge of the top section, the liquid tray being flanked by side-gutters that direct water that condenses on an interior surface of the top section to a front-gutter and through an output port, the side-gutters and the front-gutter at least partially circumscribing the liquid try, the liquid tray further comprising an input port for adding water into the liquid tray;
- an axil extending along a length of the elongated cylinder and parallel to the flat edge, the axil comprising a plurality of evaporation disks that are orientated perpendicular to the axil, the evaporation disks extending both into the water in the liquid tray and above the water in the liquid tray;
- a motor configured to rotate the axil.
