Eesha KhareFull cell phone batteries are a rarity. Between answering emails, text messaging and sneaking in quick rounds of “Angry Birds,” cell phone chargers are normal additions to tote bags. Waiting hours for a phone to charge seems like death, especially when traveling, but a new invention may soon cut charging time down to 30 seconds.

Eesha Khare, 18, invented a fast-charging device called the supercapacitor. It is miniature energy-storing device that can juice a phone to full charge within 20-to-30 seconds.

“I developed a new supercapacitor, which is basically an energy storage device which can hold a lot of energy in a small amount of volume,” she told KPIX 5 in California.

Khare – a high school student from Saratoga Calif. – grew tired of never having a full battery, leading to this creation.

“My cellphone battery always dies,” she told NBC News. Creating the supercapacitor solved Khare’s issue and also piqued her interest in “really working at the nanoscale to make significant advances in many different fields.”

The high school senior is headed to Harvard University in the fall and she’s toting her invention with her. The supercapacitator received a huge boost at the 2013 Intel International Science and Engineering Fair where Khare won the Intel Foundation Young Scientist Award. She was awarded $50,000 – sure to come in handy at Harvard – and a chance to showcase her invention to potential investors.

Khare hopes her creation will “set the world on fire,” eventually having enough energy to power automobiles.

So far the burgeoning scientist has powered a LED, but she hopes a few tweaks can lead to the placement of the supercapacitor in cellphones and other technological devices. Khare wants to cut down our dependence on electrical outlets.

Long-lasting, quickly-charged phones could be viable assets to our futures.

    It looks like she has already got her 401k worked out! Congratulations young lady!

      Why do you always refer to women and girls as ‘young lady’?

    • Anthony

      In all of my years, I have never known the term young lady to be offensive. The person is 18, she is barely into her legal majority, and is too young to drink or buy a gun. If me calling an 18 year old a young lady offends you, then I think you are the one with issues, not me.

      I know when I was her age, my elders called me a young man and I thought nothing of it. I am 53, she is a kid to me.

    • Anthony

      In my humble opinion, 18 years old qualifies her as a young lady. For the life of me, I can see nothing offensive about that term. I was certainly called a young man when I was her age.

    • The Moon in the Sky

      Of course you don’t think it is offensive. You aren’t a woman.

      It’s clear that she is young, and it is clear that she is a woman, so why specifically point it out?

      If this had been a 50-year-old man, would you have said, “Congratulations, old man!”

    • Anthony

      Simply look at the ratings of your statement, and it tells you just how little most of the readers here agree with you. In my experience calling someone a young woman or man is not negative. In the context of the story, it is an acknowledgement of great accomplishment at an early age.

      The bottom line is that if you want to be offended, you will be offended. I’m not interested in knocking chips off of your shoulder, but unless the majority of women make it clear that they find it offensive, I will keep using the term.

    • The Moon in the Sky

      Whether or not a handful of people on this site agree with me is irrelevant. There is a whole world of people out there who do.

      You didn’t answer my question.

      If this had been a 50-year-old man, would you have said, “Congratulations, old man!”

    • ScriptTease

      ….and how would you refer to her without using her name?

    • Nope

      If this had been a 50 year old woman, I doubt he would say congrats old woman either, but many people would say congrats young woman AND young man. Ageism I guess. Old is seen as a negative. Like he said it is acknowledging that someone is young and accomplished anything. This is a nonissue.

    • The Moon in the Sky

      If you do not know someone’s name, you refer to them as Ms. or Ma’am.

    • Anthony

      I imagine it would depend on the context in which the old man is being congratulated. If it is some sort of task associated with youth, being known as the old man is pretty cool.

      Either way, if you keep living, you will find out what is like to be called old yourself. Chances are, you already look old to some kid now.

      Are you seriously still on it?? Get a LIFE!

    Great invention! I’m sure it’ll be a hit when it hits the markets. Her future looks bright.

    Go girl!

  4. I’m loving the stories about these young braniacs today :-)

  5. OMG! She’s about to be set for the rest of her life!
