US Patent 9446969 Solar driven water purification and transportation system

A system and method of water purification and transport driven by solar energy. The system includes an absorbent tank containing an adsorbent. The adsorbent absorbs water vapor from raw water at night. A heat exchanger cools the adsorbent. During the day, solar energy is focused at a cylindrical or oval shaped vessel of the adsorbent tank. As the temperature of the adsorbent increases, its capacity decreases, causing it to release purified water. The purified water is transferred to a storage tank. A transmission pipe containing adsorbent granules or capillaries transports the purified water into a product tank.
