This working hypothesis involves the use of a humidity condenser with heat sink that works from a depth of 5 meters and beyond (up to 10 meters depending on the sizing requirements), using water, thermal conductive metals and good conductive gravels or soil. The dissipator cools the water so that, with a circulation pump, it cools the exchanger placed in the humidity condenser. The exchanger/condenser, in copper or aluminum, with tube and tube bundle, on the one hand produces condensed water (distilled) and cold air, and on the other hand introduces into the cooling circuit the water slightly heated during the exchange with the air. This heated water is cooled by the heat sink in the following way: 1) A correct sizing of the heatsink (diameter and depth) is evaluated. 2) On the surface of the cooling water inside the heatsink, some floating copper spheres make a first distribution of the surface heat towards the external wall of the heatsink and above them, assisted by the flow of cold air from the condenser. 3) Inside the heat sink, the copper plates (a second exchanger) convey the heat absorbed by the water also towards the metal wall of the heat sink (also made of a good conductor metal). These plates also have the purpose of providing a counter-thrust to the ground surrounding the heatsink. 4) Outside the heat sink wall there are copper wings and sheets and granite gravels (or in any case with good thermal conduction), these sheets, wrapping the external wall of the heat sink, convey the heat from the internal wall of the heatsink to the surrounding ground. 5) Optionally, the cooling water of the exchanger can be engineered with additives to accelerate heat exchanges (only valid for the configuration with the collection of drinking water which has the cooling circuit separate from the condensate one). 6) Only for the purpose of optimizing the process it is possible to use a small peltier cell or a similar tecnology on the terminal section of the primary exchanger: in a cycle in which the air is already very cooled by the water of the dissipator, the use of a very low wattage peltier just to get a 2 or 3 degree dip, for the sole purpose of making small adjustments.
No prototype has yet been built (today is 06 January 2021) and therefore some working hypotheses are reported in this article. No responsibility can in any way be attributed to the author of this article for: 1) accidents (directly or indirectly related to this article). 2) economic loss related to the construction of the condenser (whether it works or not). 3) Any other possible damage may derive from this article.
