Earthen rock matrix and water-wet bulb temperature cooling mass

Abstract

Natural and/or Processed Hydrophilic Earthen Minerals (water loving rocks) formed into an air-water interface matrix will track only a few degrees above local wet bulb temperature with the addition of water. Coating surfaces, Building Roofs and Walls, with hydrophilic earthen rocks and adding water will cool the building mass below air temperature. Wet bulb temperature is the lowest temperature that can be reached by the evaporation of water only. It is the temperature you feel when your skin is wet and is exposed to moving air. The wet bulb temperature is lower than ambient air temperature, except during rain. Water is added periodically to maintain hydration and wet bulb temperature tracking. Hydrophilic Earthen Minerals are UV Stable, expand surface area for evaporation and are fireproof.

1 . A system for cooling a structure below air temperature comprising of a coating of Hydrophilic Earthen Rocks, covering an exterior surface of a structure and a water distribution system allowing for wetting of the Hydrophilic Earthen Rock covering. 
     
     
         2 . The system of  claim 1 , Hydrophilic Rocks with high water absorbency are:
 DE—diatomaceous earth with high internal surface area and porosity, water fills the rocks. Perlite and Vermiculite both bond water to the exterior and exponentially increase the air/water surface interface. All rocks are stable in the sun's rays.   
     
     
         3 . The system of  claim 1 , Hydrophilic Rocks track just above the local wet bulb temperature with water. 
     
     
         4 . The system of  claim 1 , Water for cooling can be obtained from recycled municipal water, fresh water, rain water, surface water, well water and/or salt water.
