For people who raise livestock near Nairobi National Park, lions are a major-scale pest. Two years ago, Richard Turere, who was responsible for herding his family’s flock, noticed that lions never struck ranches where people were walking around with flashlights. So the self-taught maker, who is now 13, rigged up a system of flashing LED torches around his family’s stockade, drawing electricity from the solar panel and battery circuit that powered their TV.
Since installing the system, they have suffered zero lion attacks, unlike 5 of their neighbors. Richard was recently awarded a scholarship to the Brookhouse School in Nairobi, where he plans to study engineering.
