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-caled “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 an 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.
