It's a tiny gadget that fits inside cell phone batteries, and allows them to fully charge within 20 to 30 seconds. Typically, it takes several hours to get a full charge.

We first saw the news over on SF Gate.

Khare demoed her "super-capacitor" last Friday at the Intel International Science and Engineering Fair. The 18-year-old genius from Saratoga, Calif., walked away with a $50,000 prize for the energy storage device that can last for 10,000 charge cycles. Compare that to standard batteries, which are typically only good for 1,000 cycles.

During the demo, Khare showed off how it could power an LED light. But in the future, the device could easily be used in roll-up phones or maybe even car batteries.
