Waiting hours for a cellphone to charge may become a thing of the past, thanks to an 18-year-old high-school student's invention. She won a $50,000 prize Friday at Intel International Science and Engineering Fair for creating an energy storage device that can be fully juiced in 20 to 30 seconds. The fast-charging device is a so-called supercapacitor, a gizmo that can pack a lot of energy into a tiny space, charges quickly and holds its charge for a long time.
What's more, it can last for 10,000 charge-recharge cycles, compared with 1,000 cycles for conventional rechargeable batteries, according to Eesha Khare of Saratoga, Calif. "My cellphone battery always dies," she told NBC News when asked what inspired her to work on the energy-storage technology. Supercapacitors also allowed her to focus on her interest in nanochemistry — "really working at the nanoscale to make significant advances in many different fields."

This has already been invented by materials scientists. She has simply reproduced their work, and not invented anything new.

Well san, I am not sure what your agenda is--but apparently she did something that hasn't been done before, or she would not have won that prize. Do you really think the judges are uninformed and incapable of recognizing a significant break through in engineering?
San - if that is the case then why hasn't been made public? Why hasn't it been made available for public use if it has already been "out there?" I saw your link - but it was in theory only - I didn't see that the actual "product" was created to do what this teen girl has done! Kudos to this girl - and Epic Fail to Materials scientists for not following through on their theories!
I developed a new supercapacitor, which is basically an energy storage device which can hold a lot of energy in a small amount of volume," she told KPIX 5.
Supercapacitors are not new, sounds like she came up with a variant.
BTW, the new Mazda-6 has this i-ELOOP mild hybrid which uses Ultracaps in place of batteries.
Congratulations Esha Khare. Please continue with this creativeness.
