Indian girl invents device that can charge phone in 20 seconds
An 18 year old Indian origin girl in the US has developed a potentially
revolutionary device that can charge a mobile phone in just 20 seconds, a media
report said.The charging device has been dubbed a 'supercapacitor' by Esha
Khare of Saratoga, California, the Daily Mail reported. Khare won $50,000 for
her invention at the Intel International Science and Engineering Fair, held in
Phoenix.
Khare has only used her 'supercapacitor' to power a light-emitting diode
(LED), but says that one day her invention will power cell phones, cars and any
gadget that requires a rechargeable battery.Asked what inspired her to work on
the technology, Khare said, "My cell phone battery always dies. It has a
lot of different applications and advantages over batteries in that
sense."
The 'supercapacitor' is flexible and tiny, and is able to handle 10,000
recharge cycles, more than normal batteries by a factor of 10. Khare is a
student of nanochemistry, and is now heading to Harvard.
