Atmospheric Water Generators are machines that work on the same principle as dehumidifiers. They produce water from atmospheric moisture. The difference between them and the dehumidifiers is that the water they produce should be safe to drink.
In this video from desertsun 02’s channel on YouTube, a man shows off a simple AWG that’s he’s built himself. The explanatory paragraph for it runs
DIY Atmospheric Water Generator. Unit pulls Pure ‘distilled water’ straight out of the air! works best in hot humid conditions. this simple design pumps near freezing water thru a long section of copper coil. coil becomes very cold and dew (condensate) forms on the coil. the dew is then caught by a drip-pan located beneath the coil. *note that this unit has the added benefit of dehumidifying the air. *an AWG is essentially just a “Food Safe” dehumidifier. (my previous video shows this unit being operated primarily as a dehumidifier… the difference being that that design has plastic parts that come in contact with the water). to keep the water as ‘pure’ as possible, i used only aluminum and copper in this version. main thing with these is to keep the coils clean. if coils are cleaned after each use, the water generated is ‘distilled water’.
Of course, it raises the question that if he’s using cold water to condense the water in the atmosphere, why doesn’t he simply drink the water rather than go to all the bother of cooling and pumping it around just to get a few ounces from the atmosphere. But it’s a brilliant piece of home engineering, and scientists and engineers are building machines like these to give people in deprived, parched areas potable water. And we may need more of these machines very soon if the planet continues to warm up and desertification increases.

At this time of year I often produce water from atmospheric moisture by trying to dry my laundry hung on clothes horses in the bedroom! If I don’t open the window a little the water runs down the walls and will obviously make the place damp and mouldy, which is probably what the previous tenant had done by the looks of things.
