The technology of producing water from the air has been developed in the last twenty years, thanks to the vision of some entrepreneurs. In the vast majority of cases, a physical-chemical process of heat transfer is used to condense the water molecules present in the air, by lowering the temperature to the dew point. Commercial models require access to conventional electrical power. In other cases, the integration of wind generators or a park of solar panels as a source of energy is also promoted.

 

The problem that arises is that current technology requires that the installation site have a minimum relative humidity and ambient temperature to operate. Additionally, high energy consumption makes commercial models inefficient. For this reason, this technology is not versatile, in the sense of operating in places with different environmental conditions and where the price of electricity is high. As a result, it is more economical to purchase water from external sources than to pay for the investment in such equipment.
