Student develops a capacitor that could charge a cell phone in 30 seconds

Student develops a capacitor that could charge a cell phone in 30 seconds
18 year old Eesha Khare of Saratoga, California won the Intel Foundation Young Scientist Award, earning her $50,000 which she will presumably use to further her research while attending Harvard University.

The supercapacitor she has developed may hold the key to recharge a cell phone battery in less than a minute. Amazingly, even at this fledgling stage, the technology already can handle 10,000 charge/re-charge cycles which is 10-times better than most modern day batteries.

Khare’s invention is also solid-state which means good things for the need of new technology to be environmentally responsible. So far, the supercapacitor has been used to power LEDs and will also be able to be used in flexible environments like fabrics and bendable displays. The project is titled “Design and Synthesis of Hydrogenated TiO2-Polyaniline Nanorods for Flexible High-Performance Supercapacitors.”

She has already had big players like Google reach out to her, though Khare is not revealing the nature of any discussions. Obviously, the applications for this technology will have the potential to touch everything that uses rechargeable batteries, from cell phones to electric cars or razors.

That means people using smartphones wouldn't have to complain about their battery lives anymore!

First of all, Indian people should start to respect their woman, cause they are suffering much undue hardship. I say, good luck to her and get out of India.

I neither can agree with you, nor deny what you said. It's like.. you see both extremities here. Things have really improved and it's not at all like what people in other countries think. Media nowdays draw gruesome pictures and people believe everything .__.

No matter how much India progresses, it will always be light years behind the US (considering rate of advancement in technology). In my college, the research kits are of 1996 and computers are Win 98 with 64Mb RAM fml. If you want a better career, go to the US.

Hey kdealltheway, did you even bother to read the article? She's an American living in the U.S., not in India.

Yeah, I've bothered. I was responding to eisenbricher, not directly to an article.

And so-called geeks on PA inventing nothing while compalining about every innovation out there.

Wow thats amazing! Nows lets just hope and pray that we see this in our cell phones and other electronics within 2 years.

18 years old and making a difference, unlike you trolling and being irrelevant to the world.

God I hope she can patent that, I have a feeling since Intel sponsored the event, they take the patent. Hope I'm wrong.

Intel may file the patent but i'm sure that she will be allowed to put her name on the patent and she will recieve some of the patent income.

I can see this being an excuse for manufacturers using smaller batteries.

Who are thumbing you down???you have nothing against anyone...

I thought the capacitor would be replacing the battery not being used to "recharge a cell phone battery" but i could be wrong.
