A tiny device that can recharge cell phone batteries in as little as 30 seconds won 18-year-old Eesha Khare a major science award that will help fund her college education at Harvard University. Khare traveled from her California home to Phoenix last week for the Intel International Science and Engineering Fair, where her invention was honored as one of two winners of Young Scientist Awards. "I'm in a daze. I can't believe this happened," Khare, a senior at Lynbrook High School in Saratoga, told CNN affiliate KPIX 5.
