ACWa stands for Affordable Clean Water

The ACWa System produces clean water from hot humid air in a passive manner using geothermal and solar energy. This invention will provide the roughly two billion impoverished people in tropical climates a cheap renewable way to obtain clean water.
ACWa produces water through condensation. This uses a two-pipe system, one within the other. The inner pipe contains air cooled to 50-F° as it flows though a tunnel six feet underground. The soil at that depth stays at that temperature year round. This cold pipe serves as the surface on which hot humid air from either outside or inside the house condenses into clean water drops, which accumulate in the water collector. This water is for drinking/other uses.
ACWa’s engine is the roof-mounted metal vent with built-in solar collector, which becomes extremely hot from continued exposure to sunlight. This vent heats the air in the top two feet of both pipes, causing the air to rise thus drawing up replacement cool air in the smaller pipe and hot humid air in the larger pipe. This means the inner pipe stays cool and condenses the constant flow of hot humid air flowing in the outer pipe.
