An 18-year-old Indian-American girl (Eesha Khare from Saratoga in California) has invented a super-capacitor device that could potentially charge a cellphone in less than 20 seconds.
Ms Khare has been awarded $50,000 for developing the tiny device. She has also attracted the attention of tech giant Google for her potentially revolutionary invention.
The device can last for 10,000 charge-recharge cycles, compared to 1,000 cycles for conventional rechargeable batteries.
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.Ms Khare sees it fitting inside cellphones and the other portable electronic devices proliferating in today`s world.
