Teenager invents revolutionary device; A device which can charge a cell phone in just 20 seconds

A California teen has attracted the attention of tech giants Google for her potentially revolutionary invention which charges a phone in 20 seconds flat. The super-fast charging device has been dubbed a super capacitor by 18-year-old Esha Khare, of Saratoga - as she took home $50,000 from the Intel International Science and Engineering Fair, which took place in Phoenix this week. The device will make waiting hours for a phone to charge a thing of the past and the gizmo packs more energy into a smaller space than traditional phone batteries and holds the charge for longer. Eesha Khare made the breakthrough by creating small super capacitor that can fit inside a cell phone battery and enable ultra-fast electricity transfer and storage, delivering a full charge in 20-30 seconds instead of several hours. Communication has evolved massively in the recent past. From landline phones to e-mails, and text messaging, the world of telecommunication has now become an absolute essential part of our lives. Today, a switched off phone is the cause of frustration and often makes people feel handicapped. An average cell phone can take at least 6 to 7 hours to fully get charged. But now, a breakthrough by an 18-year-old science student might enable mobile phones and other batteries to be charged within seconds. Saratoga-resident Eesha Khare made the breakthrough by creating a small super capacitor that can fit inside a cell phone battery and enable ultra-fast electricity transfer and storage, delivering a full charge in 20-30 seconds instead of several hours. The fast-charging device is a so-called super capacitor, a gizmo that can pack a lot of energy into a tiny space, charges quickly and holds its charge for a long time. "The best part of my project was seeing its practical application. After charging my super capacitor for 20 seconds, I was able to light a LED device and that's...
