If you had a nickel for every time your phone died ... well, you wouldn’t have as much as one California teen is bound to make for her revolutionary invention. Eighteen-year-old Eesha Khare has developed a supercapacitor that could reduce cellphone charging time to 20 seconds. The current model has powered only an LED light, but it has the potential to power more—even car batteries. Big names are taking notice, too: Khare won the Young Scientist award from Intel, and Google has already approached her about the device. Next, she’s off to Harvard, and then, as she says, she’s “going to be setting the world on fire.”
It could happen, thanks to teen's invention.
