US-Indian teenager grabs $ 50,000 Intel prize for a 20-second cell phone recharge device

Phoenix ( Arizona, US), May 21, 2013: An Indian-origin, US-based teenager has taken a top prize worth $ 50,000 at the just concluded Intel International Science and Engineering Fair, for her development of a supercapacitor that could recharge it in less than half a minute. Eesha Khare, 18, of Saratoga, California, developed a tiny device that fits inside cell phone batteries, allowing them to fully charge within 20-30 seconds. Her invention has the potential to charge car batteries as well.
Esha says it can last for 10,000 charge-recharge cycles, compared with 1,000 cycles for conventional rechargeable batteries.She has used the super capacitor to power a light-emitting diode(LED) Being flexible it can also be rolled up or stitched into clothing.The prize money will help Esha go to Harvard for her higher studies.
Each year, approximately 7 million high school students around the globe develop original research projects and present their work at local science competitions with the hope of making it to the Intel International Science and Engineering Fair, a program of Society for Science & the Public.
