Designed at the Delft University of Technology in the Netherlands, this windmill is capable to turn salt water into a pure, clean drinking source.
No electricity is required for the reverse osmosis system, which could be ideal for many third world countries lacking drinking water even when they are located near the ocean. The system is able to produce water for 500 people in one day and water reservoirs can store enough drinking water for five days, to tackle small problems with mild drought or low wind situations.
The windmill runs by using the wind’s mechanical force to pump water and uses a high tech reverse osmosis membrane. The pumped water is pushed against the membrane at 60 bar of pressure and the salt is kept inside while the pure water travels across.
Currently the windmill is setup near the A13 motorway outside Delft but will be transported to Curacao for field testing later this week. TU Delft hopes to offer similar devices to small villages in dry, isolated coastal areas.
