Fresh drinking water is a disappearing commodity for many people of the world. In fact, some 750 million people in the world lack access to safe drinking water. With current climate changes the desperation for water is expected to increase. This need has triggered the rise of numerous new technologies. Most promising are those that are self-efficient. The following devices function by condensing fresh water right out of thin air – utilizing renewable energy to get the job done.
Since 2011 Eolewater has been developing the WMS1000 a wind turbine that powers itself using the wind and collects water from the humidity in the air. The WMS1000 has been able to collect an average of 62 litters an hour of fresh water in 45 percent humidity at 24 degree Celsius. After being able to produce 1000 liters a day of freshwater the turbine is currently being shipped to Abu Dhabi for the first phase of tests in extreme weather conditions. If successful, the WMS1000’s wind powered water collection can be implemented bring fresh water to people in need.
Eolewater also has systems that harness solar to power water collection. The NERIOS S3 is a solar powered water condenser. It’s the newest model and boasts 28 individual solar panels. Its ice storage system means that no battery is needed for when the sunlight is not available.
Also harnessing the power of the sun is another invention called Fontus. Designed by Kristof Retezar a Austrian industrial design student; Fontus is a solar powered water condenser for your bike.
Fontus attaches to the frame and when you ride air flows in through the filter, is cooled, water condenses then drips down into the removable bottle. Offering a way to allow bicyclists to ditch the camel-packs and make their own water as they ride.
In 50 percent humidity at a minimum temp of 68 degrees Fahrenheit Fontus can condense at a rate of 1 drop per minute. However it currently lacks an additional filter to prevent pollutants from being in the water so it’s not recommended for use in an urban setting. At a price point of 25 to 40 dollars for a unit it might be a fun investment for the alternative bicyclist.
These technologies all address a growing problem in different ways. With our need for fresh water growing by the day inventions like these might save rivers and groundwater from being tapped. They can also create a water source for people that live in even the driest of environments. Although water collection from humidity is more practical in areas where humidity is high, these strides are perhaps a step in the right direction.
