Abstract: A water desalinator that employs the use of solar concentration, evaporation and humidification, mimicking the natural hydrological cycle in a closed, modular vessel to produce freshwater from salt, brackish, brines and seawater, and a concentrate stream for further processing. Feed water is received and stored in a basin. Surface humidity is generated by the evaporation of basin water. A lens is used to focus sunlight, tracked the suns path based on biomimicry of a sunflower, on a thermal conductor. The thermal conductor has a rounded side-profile and generates a variable temperature across its radius. Water is pumped from the basin to a sprinkler head to be dripped or sprayed on the thermal conductor to generate water vapour. This water vapour consequently mixes with the air in the reaction vessel to increase system humidity. Humid air is removed from the reaction vessel and condensed in a condenser. Accordingly, the salinity concentration of input water is reduced from the output of the reaction vessel.
