Water desalination system using geothermal energy

A water desalination system using geothermal energy, comprising:

• a sloped evaporator tray housing substantially formed of functionally graded material;
• a plurality of successively stepped evaporator trays disposed within the housing, the evaporator trays ranging from an uppermost tray to a lowermost tray, each successively lower tray receiving overflow from the tray immediately above;
• a closed geothermal heat exchange system extending from the housing to a subterranean depth and back to the housing, the heat exchange system having at least one pipe disposed within the housing and beneath the evaporator trays;
• and
• a heat exchange fluid circulating within the heat exchange system.

A water desalination system, comprising:

• a sloped evaporator tray housing;
• a plurality of successively stepped evaporator trays disposed within the housing, the evaporator trays ranging from an uppermost tray to a lowermost tray, each successively lower tray receiving overflow from the tray immediately above;
• a catch basin disposed beneath and adjacent to the lowermost tray;
• a drain pipe extending from the catch basin;
• a lower glass panel disposed above the evaporator trays and housing, the lower glass panel having a slope substantially parallel to the slope of the housing, the lower glass panel having a lowermost end;
• a desalinated water collection trough disposed immediately below the lowermost end of the lower glass panel, the collection trough collecting condensation from the lower glass panel;
• and
• a fresh water collection tank communicating with the collection trough.
