Cool Stuff We Like discusses a wind turbine that pulls water out of the air:
"Give us wind, we give you water."
That's the slogan of Eole Water, the French company that has developed a wind turbine able to condense up to 1,500 liters of clean water a day right out of thin air. The WMS1000 system is self-contained: the water condenser unit is powered by an internal wind-driven generator. In addition to water, it produces 30kW of electricity.Wind turbines are not, by themselves, a good choice for producing electricity unless you are in a reliable, high wind area, because you need a reliable energy source as well, or a huge battery backup. But this is an interesting combination. As long as you have a large tank in which to store the water it is condensing out of the atmosphere, the energy output is simply a nice side effect, because the turbine does not have to run all the time. I spoke to someone recently who spent $60,000 on a well--and did not have a useful result. Something like this would be very attractive for that reason.
