A team of international researchers has managed to create a completely passive system, which uses evaporation to obtain drinking water even in the most arid regions
So far, with this type of solutions at best, it has been possible to obtain a production of about 2 liters of water per day (calculated per square meter of solar collection surface).
With the new design the technology has been considerably improved, to the point of being able to supply more than 1.5 liters of drinking water per hour.
The system consists of several layers of evaporators and flat condensers, aligned in a vertical module and topped by a transparent airgel insulation.
The prototype is still in the optimization phase and it is expected to double its efficiency and lower the price to $ 100 for a domestic model.
