Thirteen-year-old Ukoma Michael from Nigeria is one of the youngest and best upcoming tech entrepreneurs in the world. He invented a battery-operated fan that will last for up to 19 hours. He calls them “Blue Wind Fans,” and they come in different shapes and sizes from table top to free standing. Once the fans are charged, they can run for up to 19 hours! Michael makes his fans from aluminum and wire, and uses old cartons for packaging. This makes them very affordable for low income families, but the fans are presentable and modern looking, blue with a high-tech appearance.
