The earth's atmosphere is packed with a huge freshwater reserve: 13000km3. Eole Water has created an innovative technology which is able to turn this moisture into drinking water.

In remote areas without access to fresh drinking water, there is often the dual concern of a lack of electricity. French company Eole’s modified turbine not only harnesses wind for energy, but includes a compressor similar to that of a dehumidifier, which pulls in air to generate condensation. The condensate is then harvested to produce up to 1000 liters of fresh, clean drinking water each day.

Eole Water claim that a single WMS1000 turbine can provide enough water for a village of two to three thousand people. Designed to last for around 20 years the makers describe the turbine as both sustainable and autonomous. With water ever present in the air, the turbines can generate usable water with more reliability than a well or a borehole.

With the capacity to generate 30kW, it does not require an additional power source and releases no CO2 emissions. Eole have also designed an independent solar panel powered alternative, as well as a compressor which can tie into an electrical grid in areas where water scarcity is of greater concern than lack of power.

There are some significant variables to the turbine’s water production ability — those in arid areas would find water output to be less than those in more humid climates. A prototype currently in the desert near Abu Dhabi has, however, been able to produce 62 liters of water per hour.

The fantastically simple design has additions which make it easier to run and maintain in remote areas. The turbine features a large filter on its front to reduce the amount of dust pulled into the system as it sucks in air to produce the condensation. It also can be raised and lowered to allow for easier repairs of the 24 meter high turbine.

The manufacturers hope to make the WMS1000 turbines commercially available later this year, but have cited concerns about its current expense. Designed to serve communities without infrastructure, it currently costs between $660,000 and $790,000 to install a single turbine. Eole Water remains enthusiastic about the potential of the turbines, and hope that as an industrial process is developed for the technology, the price will fall with its availability.

Making water from air

The earth’s atmosphere is packed with moisture. It is a huge freshwater reserve: 13000km3. Eole Water has created an innovative technology which is able to turn this moisture into drinking water.

This is done using a condenser with a moisture exchange surface which is one meter wide and five kilometers long. It is equipped with a revolutionary “food safe” stainless steel quality alloy, especially adapted to producing drinking water. It can sustain the water creation process for decades, without risk of corrosion.

The water then flows through a five-tier water treatment system, including an ultraviolet filter, in order to make it perfectly safe to drink. The quality of water collected exceeds the drinking water standards required by the World Health Organization.

The water production machine can collect up to 1500 liters of water a day depending on the climate.

This new technology is strongly influenced by the principles of sustainable development, with air, wind or sun being the only consumables. There is no CO² released, no groundwater drilling or water surface pumping.
