A potentially game-changing invention by an 18-year-old high school student grew out of a simple problem that plagues teenagers (and just about everyone else).


“I’m a teenager and I have a cellphone and my cellphone battery always dies, so I was really looking for a way to improve energy storage,’’ Eesha Khare said on TODAY Tuesday. “That’s how I came across supercapacitors.’’

The Saratoga, Calif., teenager, who graduated from high school last week, won a $50,000 prize on May 17 at the Intel International Science and Engineering Fair for creating a device that can store enough energy to potentially charge a cellphone in 20 to 30 seconds. In addition, the device lasts for 10,000 charge-recharge cycles, compared to 1,000 cycles for most cellphone batteries.

“It charges very quickly and can store a lot of energy,’’ Khare said. “The cool thing is it’s at the nano-scale, so (it's) really a lot thinner than one strand of hair.”

Khare has not used her invention to recharge a cellphone yet, instead demonstrating its capability by using it to power a light-emitting diode (LED). If used on cellphones, the supercharger would slide on to the phone’s battery to juice it up in a matter of seconds. The technology is not available to consumers yet, and it could be years until it is.

“I think it will take a couple years more,’’ Khare said. “There’s still a lot more to be done with the supercapacitor device, but it’s definitely coming soon in the future.”

At an Intel event in Phoenix, Khare won the Intel Foundation Young Scientist Award, taking second place overall in the world’s largest high school science research competition. She beat out more than 1,600 finalists from 70 countries. She said on TODAY that she has been approached by several companies to continue her research, but is currently focused on attending Harvard University in the fall.

sorry for the double post didnt mean to post twice

delete the other one.

it wont let me it says wrong password

>>4 Weird, but I guess we can all let this one slide, double posts happen.

>>1 I need one of these so bad.

*koff*feelslikethisgoesintechbutahwells*koff*
>>1 Now they just need to concentrate on fitting electric vehicles with this.

I saw this on CNN Student news a few weeks ago in school and I have to say, I want one. This young girl is amazing and I wish that I had nearly half the talent that she had.

Damn, that is going to make the big companies mad. Maybe that's why they have been making chargers so different for every single type of phone/ipod around recently.

If she used carbon nanotubes its not new, but maybe the first one to use them as a battery cell.

That's amazing! Hopefully it won't take too long before it is ready for the public.

Awesome!

I'm thinking this is not eco friendly, if so forget it..

>>8 I was thinking that too. At one point I made the comment that it would be smarter for Apple to just make their chords longer so we didn't have to go back and get new ones, then I realized, they aren't losing business because of their chords. It may be annoying, but that way they don't lose costumers and they get more money. It's bloody genius for them.

>>13 10ft Extension cord...

>>12

"Thinking" it is not, doesn't mean it's not.

Bump

>>12 and how do you call autobatery then? if it is or is not eco friendly depends on how we recycle remaining waste.

>>8 i bet companies just started to fight about buying exclusive rights for patent registering. thiner batery, lighter device, more power. this may be the missing step between todays cells and laptops and future ones.
