Now here’s the invention that we’ve all been waiting for: A device that instantly charges our cell phones.
A gadget like this might soon be on its way thanks to a bright 18-year-old from Saratoga, Calif., who was recently honored at an international science fair.
Eesha Khare is the mind behind a super-powerful and tiny gizmo that packs more energy into a small space, delivers a charge more quickly, and holds that charge longer than the typical battery. Khare showed off her so-called super-capacitor last week at the Intel International Science and Engineering Fair in Phoenix, Ariz. In her demonstration, she showed it powering a light-emitting diode, or LED light, but the itty-bitty device could fit inside cell phone batteries, delivering a full charge in 20-30 seconds. It takes several hours for the average cell phone to fully charge.
Khare also pointed out that the super-capacitor “can last for 10,000 charge cycles compared to batteries which are good for only 1,000 cycles.”
Khare’s invention is flexible and could be used in roll-up devices and might even have applications for car batteries.
The judges at the science fare were wowed by Khare’s brilliant invention and the senior at Lynbrook High School in San Jose received the Intel Foundation Young Scientist Award and $50,000.
“With this money I will be able to pay for my college and also work on making scientific advancements,” Khare told a cheering audience after receiving the prize money.

Jimmy Carter started the first great Solar Panel rave in 1973.
That was 40 freakin years ago.
Have they made it better? Hell Yeah!
Can it compete with conventional energy?
Hell No!
If it did we would see solar panels everywhere..
It is a limited application and on the wider green level, it is a scam.
Some jackass got all up on me in like 2008 out of the blue, she was saying what a jackass conservatives and particularly GWB was.
I did not bring it up.
She was just a pissed off know it all.
She informed me that she was gonna live off the grid on a 2’x1’ solar panel LOL
I told her she might charge the radio with that, or the cell phone, but you aint gonna run the fridge or AC with it, and have you considered water?
And it aint gonna happen in 20 seconds, LoL
Yeah,
A trickle charge.
It does have specialty applications, but you aint gonna run solar panel factory on solar energy.
There is to much loss.
you aint gonna run a solar panel factory on solar energy.
That is the bottom line.
Imagine the energy loss lighting all the dim bulbs.
I don't build energy-producing devices. I specialize in exactly the opposite :-)
I will run my refrigerator and freezer with LPG. The enameled cast iron cook range is wood fired, as is the Vermont castings stove in the living room.
So, why will I have a generator? To charge the batteries during the day, that will provide electricity for lights, the computer, and run my hairdryer later.
Where I live, the rain can be measured by the foot. Collection off of roofs is substantial. Just filter and chlorinate.
Good kid, but she’d better get out of California before trying to make a business selling it. She’ll be taxed out of existence.
