1) Lion Lights: A 13-year-old Kenyan boy came up with an ingenious solution to keep lions from feasting on his family’s cattle. Young Richard Turere, who lives near Nairobi National Park, noticed that the lions shied away from the family farm if someone was walking around with a flashlight. So he rigged up a system of flashing LED bulbs on poles. Turere came up with his “Lion Lights” despite lacking any formal electronics or engineering training.
