An 18 year-old high school student from California won $50,000 last week for creating an energy storage device that can be fully charged in under 30 seconds.
“My cell phone battery always dies,” said Eesha Khare, echoing a sentiment that we all share.
But instead of just shrugging her shoulders, Eesha put her problem-solving skills to work. She created a supercapacitor, which is a device that packs a lot of energy into a very tiny space. It also charges quickly and holds that charge for a very long time — up to 10 times longer than conventional rechargeable batteries.
As for Eesha, the sky is the limit. Her device has already been used to power LED lights, and she sees cell phones as the next logical step. But that’s not all.
“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.”
Way to go, Eesha. A nation of grateful cell phone users thanks you for your ingenuity.
