The WaterMill is an elegant solution for providing pure drinking water, by literally condensing water vapour in the air into an internal chamber. According to the ElementFour website, atmosphere contains between 4g and 25g of water per cubic metre. Of which, the WaterMill can convert between 10 and 40% of that water vapour into drinkable water.
Since water in the atmosphere is replenished by natural events, such as evaporation and plant transpiration (as well as respiration and perspiration from humans!!), the atmosphere is a continuous source of water vapour. The condenser can extract up to 12 litres of water per day, which is plenty of drinking water for a whole family.
The WaterMill is designed for residential use, to be installed outside the home. The green gadget is completely self-regulating, maintaining it’s own balance of energy consumption and water production. Theoretically, if the unit was solar powered too, you’d have a completely free source of drinking water. I just wonder what protection is built in to protect against Legionnaires Disease typically associated with cooling units.
