Since the air contains about 4,000 cubic miles of water (about the size of all of the Great Lakes,) Element Four’s WaterMill can produce up to 13 quarts a day. It mounts to the exterior of your house and brings it inside to your refrigerator, spigot, water cooler or backsplash dispenser. The device is self-regulating and the company claims that it has maximum water production with minimal energy consumption. Contact Element Four for more information.
