Submission + - Charge your cellphone in 20 seconds (nbcnews.com)

GoJays writes: An 18 year old from Saratoga California has won an international science 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 the inventor Eesha Khare.
