Eesha Khare, 18-year-old Indian-American girl has recently invented a super-capacitive device, which can potentially charge a cell phone in just less than 20 seconds. Khare is from Saratoga, California and was awarded the Young Scientist Award by the Intel Foundation for developing the tiny device.
The device fits inside the mobile phone batteries which can allow them to charge within 20 to 30 seconds. The super-capacitor has plenty of energy in a tiny space, charges quickly and holds the charge for a long time. Khare has been awarded $50,000 for developing the tiny device.
Moreover, the young mind has also attracted attention from search engine giant Google, in what could be a potentially revolutionary invention. The 18-year-old said that the device can last for 10,000 charge-recharge cycles, compared to the 1,000 cycles for conventional rechargeable batteries. When the teenager was asked what inspired her to make the device she said, “My cellphone battery always dies”. The device also inspired her to focus on her interest in nanochemistry.
So far, the device has been tested on an LED light, but it also has a good chance of working in other devices, such as mobile phones.
