Wind Turbine Creates Water from Thin Air_Featured_, Alternative Energy, Technology Wednesday, May 2nd, 2012
(CNN) Wind turbines have long produced renewable energy but a French engineering firm has discovered another eco-purpose for the towering structures.
Eole Water claims to have successfully modified the traditional wind turbine design to create the WMS1000, an appliance that can manufacture drinking water from humid air.
The company aims to start rolling out the giant products for sale later in 2012, initially focusing on remote communities in arid countries where water resources are scarce.
“This technology could enable rural areas to become self-sufficient in terms of water supply,” says Thibault Janin, director of marketing at Eole Water.
“As the design and capabilities develop, the next step will be to create turbines that can provide water for small cities or areas with denser populations,” he adds.
Eole Water is currently displaying a working prototype of the 24 meter tall WMS1000 in the desert near Abu Dhabi that has been able to produce 62 liters of water an hour, says Janin.
He explains that the technology works by first generating electricity in the traditional manner of a wind turbine. This power enables the entire water generating system to function.
The next stage sees air sucked in through the nose of the turbine via a device known as an “air blower”.
All air trapped during this procedure is then directed through an electric cooling compressor situated behind the propellers. This contraption extracts humidity from the air, creating moisture which is condensed and collected.
The water gathered at this stage is then transferred down a series of stainless steel pipes, which have been specially modified to aid the water production process, to a storage tank in the base of the turbine.
Once there, the water is filtered and purified before it is ready for use and consumption.
One turbine can produce up to 1,000 liters of water every day, depending on the level of humidity, temperature and wind speeds, says Janin.
“This is enough to provide water for a village or town of 2,000 to 3,000 people,” he adds.
