Two female chemical engineer students developed a prototype that converts polluted water into clean energy through a purifier and an electrolyzer. Jeimmie Gabriela Espino Ramírez and Lisset Dayanira Neri Pérez, at the National Polytechnic Institute of Mexico, are the creators of this device they named Gimfi, which in the Otomi language means “dirty water”. The students designed Gimfi to be both portable or nonportable in order to provide clean fuel for stoves and ovens in marginalized areas. The filter is made of natural elements like cotton, sand, volcanic rock, gravel, marble and charcoal. The hydrogen generated is currently produced with electricity but they plan on adapting it to solar panels, which would make Gimfi even more sustainable. Photo credit: Serg Velusceac/El Universal
