Water Goes Off the Grid

A Canadian company rethinks atmospheric-water generators


Happy Now?: Will the chance to generate drinking water
from the air make consumers smile?

The escalating cost of electricity has sent a growing
number of consumers in search of ways to generate
electricity at home. Element Four, based in Kelowna,
B.C., Canada, is betting that with bottled-water
consumption increasing and aging water distribution
systems, water will be the next commodity consumers will
want to produce at home. The company has done what it
says is a top-to-bottom reinvention of the
atmospheric-water generator—a device that pulls water
from the air by cooling it to the point that
condensation forms and then keeps it sterile for
drinking. 


Element Four’s WaterMill is a 300‑watt generator that
makes up to 12 liters of drinking water per day—enough,
it says, for your typical North American household. At
Kelowna’s rate of 6 U.S. cents per kilowatt-hour, the
cost comes to about 3 to 4 cents per liter

And it's Canadian!

In combination with sustainable power generation - solar, wind, thermal differential, biofuels, biogas - this would definitely make long term, sustainable independence possible in very remote locations. Or in your city apartment, for that matter.
