An 18-year-old from Saratoga, California could make waiting for your cell phone to charge a thing of the past. The teenager, Eesha Khare, has invented a so-called "super capacitor" that can pack a lot of energy into a very small space.
Additionally, it can still hold a charge for a long time, and lasts around 10,000 charge-recharge cycles. Most rechargeable batteries today can only last about 1000 cycles before they need to be replaced. The tiny device could fit inside cellphones, delivering a full charge in under a minute. The device even has the potential for applications in car batteries as well.
Khare showed off her device powering a LED at the Intel International Science and Engineering Fair. The project won her the Intel Foundation Young Scientist Award, and $50,000.
“With this money I will be able to pay for my college and also work on making scientific advancements,” Khare told the audience after winning the prize.
