An 18-year-old Indian-American girl has invented a super-capacitor
device that could potentially charge your cellphone in less than 20 seconds.
Eesha Khare, from Saratoga, California, was awarded the Young
Scientist Award by the Intel Foundation after developing the tiny device that
fits inside mobile phone batteries, that could allow them to charge within
20-30 seconds.
The so-called super-capacitor, a gizmo that can pack a lot of
energy into a tiny space, charges quickly and holds its charge for a long time,
NBC News reported.
Khare has been awarded USD 50,000 for developing the tiny device.
She has also attracted the attention of tech giant Google for her potentially
revolutionary invention.
According to Khare, her device can last for 10,000 charge-recharge
cycles, compared with 1,000 cycles for conventional rechargeable batteries.
"My cellphone battery always dies," she said when asked
about what inspired her to work on the energy-storage technology.
Super-capacitors allowed her to focus on her interest in
nanochemistry "really working at the nanoscale to make significant
advances in many different fields."
The gadget has so far only been tested on an LED light, but the
good news is that it has a good chance of working successfully in other
devices, like mobile phones, the report said.
Khare sees it fitting inside cellphones and the other portable
electronic devices proliferating in today's world.
"It is also flexible, so it can be used in rollup displays
and clothing and fabric. It has a lot of different applications and advantages
over batteries in that sense," Khare added.
