During the 3rd meeting of the lens colombia network, part of the international lens, a hackathon was made based on the 25-liter challenge launched during the February event in South Africa. What was sought is that groups of students from different universities, during the first weeks of class, develop a product that can meet the parameters of this challenge in a home: is it possible for a person to live using only 25 liters of water ? In this way, it is expected that water problems that occur in different cities of the world can be resolved in some way. The results were presented, and improved during the September 19 event in Medellin, Colombia, creating interdisciplinary teams among participants from all universities.
Here you can find a brief explanation of the development of the projects:
