Cristian Alejandro de León Gómez, a student at the Polytechnic University of Chiapas, has aroused the interest of many with a project that, apart from being innovative, could be beneficial for society and for some of the most inaccessible communities in our country.

Since high school, Cristian had the concern to develop a way in which rainwater could be made drinkable. After watching a documentary on how this could be achieved through a distillation process, Cristian's interest increased.

A solar water still is the project that this young man has developed in the Environmental Technology Engineering career. '' A solar water still that is simple and inexpensive '' as Cristian described it. This removes salts, fungal spores, bacteria and other contaminants that rainwater may contain.

Today there are hundreds of communities that experience hardships to obtain the drinking water they require. The contamination of rivers and aquifers in our country is an alarming issue that affects the members of these communities, who are the most vulnerable. That is why this project can be a light of hope for those who lack the vital liquid in their daily lives.

Currently, this still can obtain up to 10 liters of water per day, coming from rain or air conditioning systems. For this reason, the project was selected to be presented at the National Youth Meeting for Sustainable Development in Mexico, which took place a few days ago in Xochitepec, Morelos.
