1. A water farm comprising:
a water storage tower;
at least one pump, powered by a green power source selected from the group consisting of a wind power source, a solar power source, a wave-powered source and a photovoltaic power source, that pumps water from a water reservoir to the water storage tower;
a plurality of vertically stacked pipes for releasing water from the water storage tower and conveying the water to a day tank;
a plurality of desalination units fluidly connected to the day tank, the plurality of desalination units providing desalinated water to a common output pipe, each desalination unit being a solar desalination unit comprising:
a bottom section and a top section, each being horizontal cylindrical segments 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 that is sealed to an optically transparent bottom surface to provide an evacuated area that has a pressure of less than one atmosphere;
the top section comprises 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;
wherein the top section comprises a hydrophobic coating proximate an apex of an internal surface of the top section, the hydrophobic coating facilitating collection of water in the at least one side-gutter; and
a potable water storage tank fluidly connected to the common output pipe for receiving the desalinated water therefrom;
wherein the plurality of desalination units are arranged in a vertical stack.
