Drinking water, from air and sunlight

Imagine living with limited water, with only one tap for a family group and to access it, one would have to travel long distances. This is what the UNICEF report indicates, it talks about the difficulties to live with drinking water in many regions of the planet earth.

Although many communities have implemented techniques such as rainwater harvesting and water condensation techniques, the latter requires connection to the electricity grid, increasing electricity consumption, which is ultimately much higher than the communities can afford to pay.

Source Global has presented a system that uses solar energy to condense clean drinking water free of contaminants, including air pollutants. No additional electricity or carbon is required.

This system not only makes water drinkable, but it also manages to mineralize the water to obtain the ideal hardness and flavors.

The portal interestingengineering.com interviewed one of the representatives of the company, who commented on the hydropanels and how they generate passive condensation and means to collect the water obtained.

These panels called Hydropanel consists of a traditional solar panel that provides the energy required for the entire system, on the sides are two dark rectangles, which function as solar thermal panels, and are responsible for collecting as much thermal energy as possible.

Internally, the panels have a higher temperature than the surrounding air, obtaining pure water, even in extreme environments such as deserts or uncertain environments such as those with high levels of pollution.

The colder environment, being charged with water vapor, condenses into liquid water, which is collected in a patented hygroscopic material inside the system, allowing the water molecules to pass through the membrane.

Depending on the climate, approximately 72 liters of water can be produced per panel per month, however, it is highly dependent on the humidity of the environment where the system is installed.

It works entirely with sunlight, which makes it feasible for areas where water is a very valuable resource, obtaining quality drinking water without energy expenditure.
