Sun-pumped, ground-cooled condenser · 模型 129206
This is an entry for the NBD Nano competition at http://grabcad.com/challenges/countertop-atmospheric-water-generator . My suggestion is to coat the inside of a hose with the NBD Nano condenser surface. This will allow for an extremely simple and cheap design for an ultra-efficient water condenser that is "turbocharged" by the energy of the sun and by the vortex-mixing of the air inside the hose. The design described below should be many times more efficient than other designs that just rely on the breeze to bring moisture into contact with the NBD Nano condenser surface. Overall this design has very few parts, is quick and easy to set up, should produce high condensing efficiencies, and is almost arbitrarily scalable by just adding more materials. This design has no moving parts, and requires no external energy source other than sunlight. The design could be constructed out of completely recyclable materials. By coating a hose with the NBD Nano surface and then passing air through the hose, rather than just exposing a condenser surface to a breeze, the proportion of a given volume of incoming airflow that is exposed to the surface is dramatically increased, because as air passes through a hose, it adheres to the surface of the hose, creating constant toroidal rolling vortices (like smoke rings, but more chaotic) along the length of the inside of the hose. (This principle is used in your body in the esophagus, to capture as much dust as possible on the mucus membranes before air enters the lungs.) In my design I bury a coil of hose with NBD Nano lining underground, at a sufficient depth that the surrounding ground is much cooler than the air above ground. (This probably requires a depth of a meter or two; too deep and lifting water back up from that depth will require too much work.) The system draws air from an above-ground air intake down and past a buffer tank, then through the underground hose coil. Because the temperature underground is lower than the air temperature on sunny days, this will increase the efficiency of the condenser surface even further by cooling the air, increasing condensation. Above ground, another coil of hose, colored black and exposed to sunlight, is connected to the first coil such that when the sun heats the above-ground coil, the air inside it expands and rises, escaping from the air outlet at the end of the hose, which is at the highest point. This sun-powered "convection pump" creates the suction that pulls the ...
