Swiss Researchers Create Device That Produces Drinking Water From Moisture Without Using Energy.
How many times have we found ourselves in situations where the humidity around us is so high that it represents a real obstacle to well-being? Think about all those areas or days when it really feels like the air is “heavy” to the point where it is difficult for us to do anything.
Some have had the idea of using all this moisture for something positive, namely to produce drinking water. How? ‘Or’ What? 24 hours a day and without major energy expenditure, obviously relying on clean and renewable sources.

The Swiss Federal Institute of Technology Zurich (ETH) has developed a device that could truly revolutionize water production. Although atmospheric water generators have been around for years, the ones that are in use require a lot of energy to carry out the process of extracting water from atmospheric moisture and then making it drinkable.
So that’s where the Swiss alternative we are going to talk to you about comes from. ETH Zurich, with its invention, decided to go beyond the limits of use which, until now, have slowed down the spread of these innovative and important systems for many reasons, water scarcity among others.
The novelty proposed by Swiss scientists consists of an innovative condenser, capable of operating 24 hours a day, without consuming energy. A very different device, therefore, from its previous counterparts, which could extract water by exploiting the thermal amplitude day-night and which were therefore limited to operating at night.

But how does this revolutionary system work? The sun’s own energy comes to its aid. A special glass cover, coated with polymer and silver, reflects solar radiation and returns heat to the outside, and thus manages to cool the device by creating condensation, which collects in the form of water at the bottom.
All of this means that the system could produce more than twice the amount of water each day than previous devices. The first tests have given encouraging results, the potential of this device, if it is generalized, is immense. Think about how many drought issues and drinking water scarcity it could solve.
