It's really thrilling to see the kinds of things made by these young kids in these science competitions. And this young lady came up with something with immediate practical applications:
An 18-year-old science student has made an astonishing breakthrough that will enable mobile phones and other batteries to be charged within seconds rather than the hours it takes today’s devices to power back up.
Saratoga, Calif. resident Eesha Khare made the breakthrough by creating a small supercapacitor 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 nano-tech device Khare created can supposedly withstand up to 100,000 charges, a 100-fold increase over current technology, and it’s flexible enough to be used in clothing or displays on any non-flat surface.
