Intel International Science And Engineering Fair 2013 

Intel:

With the rapid adoption of portable electronics, Eesha Khare, 18, of Saratoga, California, recognized the crucial need for energy-efficient storage devices. She developed a tiny device that fits inside cell phone batteries, allowing them to fully charge within 20-30 seconds. Eesha’s invention also has potential applications for car batteries.

Amazing stuff by someone my age. And yet, because this fair attracts so much incredible talent, Khare’s invention didn’t even win the top prize.
