Muturi Kamau was eleven years old and living near the boundary of a Kenyan wildlife conservancy when he watched the anti-poaching team arrive too late again. The poachers had been and gone, and one of the elephant families he had been observing since early childhood was reduced by one. Muturi had been reading about elephant communication in a donated science book, specifically about the infrasound calls that elephants make when they detect threats low frequency rumbles below human hearing that propagate through the ground and can be detected kilometers from the source. Elephants make these calls when they sense danger, including human intrusion. He thought about this for three months. Then he built something. Using repurposed electronics from a broken radio, piezoelectric sensors salvaged from a discarded musical greeting card, and copper wire purchased with three months of saved school lunch money, Muturi built a ground-contact infrasound sensor that could detect elephant distress calls through soil vibration and trigger a radio alert to the ranger station 800 meters away. The first prototype failed. The second worked intermittently. The third, which incorporated a modification suggested by his physics teacher, detected an elephant distress call at 2:47 AM on a Thursday in March and sent an alert that brought rangers to a section of conservancy boundary where they intercepted a poaching party before they had discharged a weapon. The system had worked. Muturi's device has since been replicated in fourteen conservancies across East Africa with the support of conservation technology organizations that have developed his basic principle into a more robust system while preserving his core innovation. He was awarded a full secondary school scholarship. He has been asked repeatedly what he wants to be when he grows up. He says he does not want to be anything when he grows up he wants to be what he already is, which is someone who solves problems for elephants. He is twelve now. The conservancy's elephant population has not lost a single individual since his system came online.
