Abstract: A passive solar water distiller is an apparatus that utilizes sunlight to maximize the output of clean water with increased surface area for evaporation and condensation and effective means to retain and store heat. The apparatus includes a retaining basin, a plurality of evacuated tubes, a vapor-enhancing system, a plurality of transparent condensing covers, and a gutter system. The retaining basin houses contaminated water. The plurality of evacuated tubes heats the contaminated water within the retaining basin with solar energy. The vapor-enhancing system facilitates the vaporization of the contaminated water, leaving the contaminants within the retaining basin. The vapor-enhancing system also stores heat so that the apparatus is able to release heat and operate during nighttime hours or while there is a lack of direct sunlight. The plurality of transparent condensing covers increases the surface area for condensate of clean water to drip into the gutter system for collection.
