Solar water desalination/purification device

A solar water desalination and purification device, comprising:

• a) a liquid-tight outer containment, said outer containment collecting liquid that forms from condensing water vapor;
• b) an inner containment disposed within said outer containment, said inner containment being liquid-tight to contaminated water, said inner containment is made from hydrophobic material that allows water vapor to pass through said material as the sunlight evaporates the contaminated water within said inner containment;
• c) said outer and inner containments are substantially thin and planar in the shape of an envelope;
• d) said inner containment including first and second opposed sheets of material;
• e) a plurality of supports to separate said opposed sheets from each other such that said opposed sheets are substantially parallel to each other so that the contaminated water inside said inner containment is kept to a substantially uniform thickness;
• f) an inlet communicating with said inner containment for allowing the contaminated water to fill said inner containment;
• and
• g) an outlet communicating with said outer containment to allow discharge of condensed water vapor collected within said outer containment to be used as drinking water.
