Quick boost for your gadgets

Consider a situation where you need to attend a very important meeting and you forgot to charge your all important tablet PC (Without which you are dummy,pun intended ) last night and you have a very little time to reach the meeting place crossing the irritating traffic hurdle,what will you do? Hopeless?? Not any more!!! These kind of situations are quite common and we abuse ourselves for our negligence. A California based teenager's project in INTEL International Engineering and Science FAIR 2K13 addressed this problem and grabbed so much of attention in the technical fraternity.
Eesha Khare, an 18year old teen of Lynbrook high school ,Saratoga, calif has developed a super capacitor that can charge your phone with in a span of mere 20-30 seconds. Puzzled!!!!


What is a Super capacitor??
A super capacitor is a Electric Double Layered Capacitor (EDLC) which doesn't possess the conventional Solid dielectric. These capacitors are the energy storage devices that have a long cycle life and can store a lot of charge per unit volume. But these capacitors hold less amount of charge compared to traditional batteries. This is the reason why these super capacitors couldn't replace the traditional batteries though they possess high charge storage per unit volume.
Eesha Khare modified the design and built this super capacitor with a special nano structure. Due to this the capacitor can hold more charge per unit volume. In addition to this it can charge very quickly and also possess more number of charging cycles. It has the capability of 10,000 cycles in contrast with the 1,000 cycles of usual batteries. Its always a great concern that our gadgets take a lot of time to charge to its maximum and many attempts were made to reduce the peak charging time. This approach reduces the charging time greatly.
    In the science fair she demonstrated the working model by charging the super capacitor for 20seconds and operated an LED device. Her view is that instead of an LED device we can just use our laptops and mobile phones to charge using the same capacitor. For her tremendous work in this area she received a whooping sum of $50,000 and Young scientist award from Intel and also generated revenue from Google and will be attending Harward this fall. What this article and the work of Eesha conveys to the young engineers is that age is not at all a barrier in this technical world, the ability think different and confidence to execute it matters in achieving these sort of world changing Inventions.
