A little more than a year ago, on a trip to Nairobi, Kenya, some colleagues and I met a 12-year-old Masai boy named Richard Turere, who told us a fascinating story. His family raises livestock on the edge of a vast national park, and one of the biggest challenges is protecting the animals from lions—especially at night. Richard had noticed that placing lamps in a field didn’t deter lion attacks, but when he walked the field with a torch, the lions stayed away. From a young age, he’d been interested in electronics, teaching himself by, for example, taking apart his parents’ radio. He used that experience to devise a system of lights that would turn on and off in sequence—using solar panels, a car battery, and a motorcycle indicator box—and thereby create a sense of movement that he hoped would scare off the lions. He installed the lights, and the lions stopped attacking. Soon villages elsewhere in Kenya began installing Richard’s “lion lights.”
