French company Eole Water has announced that they have developed and are now in the process of selling wind turbines that have been modified to produce fresh drinking water. Company reps say the new turbines should be a boon to remote communities that have limited access to fresh drinking water.
The initial product, called the WMS1000 is capable, the company claims, of producing up to 1000 liters of clean fresh water every day in a humid climate. They also say the turbines are based on existing technology and are easy to maintain and use.
The turbines work by combining two current types of technology; traditional generation of electricity using wind as the driving force, and compressors commonly used by dehumidifiers and refrigerators. Anyone who has ever seen a dehumidifier in action can understand right away how the new turbines work. Air is pulled in, cooled and compressed, causing moisture in it to condense to water where it can be removed and used.
The new turbines create electricity in the same way as other wind generators, some of which is used to run the compressor. The water that is produced drips down to the base of the turbine tower where it is filtered and delivered for use. Most that buy and use such a system would also likely need to add a collecting tank to hold water for use during peak times.
