18-year-old's breakthrough invention can recharge phones in seconds

An 18-year-old science student has made an astonishing breakthrough that will enable mobile phones and other batteries to be charged within seconds rather than the hours it takes today's devices to power back up.

Saratoga, Calif. resident Eesha Khare made the breakthrough by creating a small supercapacitor that can fit inside a cell phone battery and enable ultra-fast electricity transfer and storage, delivering a full charge in 20-30 seconds instead of several hours.

The nano-tech device Khare created can supposedly withstand up to 100,000 charges, a 100-fold increase over current technology, and it's flexible enough to be used in clothing or displays on any non-flat surface.

It could also one day be used in car batteries and charging stations not unlike those used by the Tesla Model S, which includes "supercharger" technology that promises to charge vehicles in 30 minutes or less.

“I’m in a daze," Khare told CBS San Francisco after being honored among the three winners at the Intel International Science and Engineering Fair in Phoenix over the weekend. "I can’t believe this happened."

Over 1,600 finalists from around the world competed in the science fair for a $75,000 scholarship grand prize awarded by Intel. Runners-up received $50,000 scholarships.

Khare was the runner-up to 19-year-old Romanian student Lonut Budisteanu, who created a low-cost artificial intelligence that can drive vehicles. She tied with Louisiana 17-year-old Henry Lin, who figured out new ways to measure dark matter and energy in space.
