(Newser) – Prepare to feel inadequate: 18-year-old California student Eesha Khare has created a supercapacitor that could recharge a cellphone battery in 30 seconds. The invention won her $50,000 in the Society for Science & the Public's huge international science fair, beating out more than 1,600 others from over 70 countries, CBS SF Bay Area reports.

Khare explains her project like so: "To improve supercapacitor energy density, I designed, synthesized, and characterized a novel core-shell nanorod electrode with hydrogenated TiO2 (H-TiO2) core and polyaniline shell," CNET reports. So, uh, it's ... really fast. Khare now heads to Harvard.

This story has it all wrong. The 'invention' is not a charger at all, and is not a suoercapacitor but a specific way of making the suoercapacitor as she describes. I am all for the use of super capacitors instead of batteries, but this step is only one of many that must be taken in order to get there.

An LED is not a mobile phone. Until this is shown to work on a cell phone and be feasible for mass production at a reasonable price then it is nothing more than a nice idea with lots of speculation.

Eesha Khare won $50K and is Going to Harvard. Meanwhile, we're all on here trying to convince ourselves we're better than the people we're arguing with. Winning!
