These 16 individuals under 20 have all invented solutions that have somehow eluded those who can legally drink. Many of these kids were inspired by simple necessity. Others were driven by compassion. Some of them were just doing science fair projects. Eesha Khare: This 18-year-old from Saratoga, California, was still in high school when she invented a battery that can be charged in 20 seconds. It also lasts 10 times as long as a standard battery. Ryan Patterson: The inability to communicate with most hearing people makes life difficult for deaf persons. Knowing this, Colorado-born Ryan invented a glove that translates sign language. It's simply a golf glove that uses sensors, a radio frequency transmitter, and a microcontroller to interpret hand movements. He was 17. Why didn't anyone else think of this? Raquel Redshirt: Growing up in New Mexico's Navajo Nation, Raquel experienced poverty so extreme that her family and neighbors often couldn't afford electricity, making it near impossible to cook anything. So at 16, she discovered a way to make solar-powered ovens using the simple materials collected around the area. Working with old tires, aluminum foil, shredded paper, and dirt, she made these usually expensive ovens for the people in her community. Have you built any ovens for your neighbors lately?
