A machine developed by an 82-year-old Spanish engineer, Enrique Veiga, is capable of producing drinking water from air. The inventor believes that the machine can be useful in ending water needs in countries where the scarcity of this resource is a daily problem.

"The goal is for us to reach places like refugee camps where they don't have clean drinking water," Veiga tells Reuters quoted by Notícias ao Minuto. "People were dumbfounded in the villages we visited in Namibia, they didn't understand and asked where the water came from."

Veiga's machine is capable of generating between 50 and 75 liters per day, with the largest versions of this machine reaching up to 5,000 liters. "Our idea is not only to make a device that is effective, but that is useful for people, who have to walk miles to fetch water or dig wells," Veiga said.

This machine was originally invented by Veiga in the 1990s, but at the time had some limitations that did not make it a viable option, such as the inability to operate with temperatures above 40ºC or humidity above 8%.

In the meantime, the machine continued to be developed and is now prepared for this type of situation, being able to withstand temperatures up to 40ºC and humidity levels between 10 and 15%.
