University of Sheffield student Jon Leary was required to “make something useful out of rubbish” as part of his dissertation. What he ended up doing was transforming lives. As part of his studies as a Mechanical Engineering major, Jon spent four months in Guatemala. There, he introduced the locals to his bicibomba movil, a mobile bicycle-powered water pump. Now, using cast-off bicycles and discarded pumps, Guatemalan farmers can irrigate their land much more easily and effectively than ever before.
