Brilliant teen creates device that charges cell in 30 seconds!

[ismnotwasm]

Eesha Khare is an 18-year-old high school senior. She’s going to Harvard in the fall and uses her cellphone. Typical 18-year-old girl stuff. Oh, she also invented a supercapacitor that charges cell phones in 30 seconds! According to Clutch:

“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.”

Apparently she developed the device because she got tired of her phone not being charged. When my phone is dying, the best I can think to do is log off of Twitter for a while. This young woman is sharp!

Not only that, she’s doing it with great intentions and ambitious hopes for all of our futures.

“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.”

She’s smart and invested in sustainability. So dreamy! You go girl!

1. Sorry, but it's not new.

Supercapacitors have been around for a while now.

You can buy some here.

Here's some more information about them.

Why aren't they used in cell phones already? They leak. You charge it up very, very, very fast, but it can't hold that charge for very long even if you don't use the phone.

2. She probably made her own using existing tech

Misleading title certainly in that case.

So I wonder just an 'emergency' charger, I mean if it can be used the way?

Oh Wait, Another link!

On Monday, the announcement went out: Over in Arizona, 18-year-old high school student Esha Khare of Saratoga, Calif., just made history by inventing a new super-battery that can:

Hold more electric power than an ordinary battery
Hold this power longer without going "dead"
Change its shape to accommodate battery designs other than your basic "rectangular solid"
Endure 10,000 recharge cycles -- 10 times more than your average rechargeable battery can
And best of all -- charge fully in as little as 20 seconds

Impressed yet? You should be. For the time being, all Khare has powered with her revolutionary "supercapacitor" is a single light-emitting diode. Pretty small potatoes, to be sure. But considering that this young lady was working under a high school student's budget, it's still quite an accomplishment, and it's easy to see how a truly flush multinational corporation could scale up her gizmo in a jiffy. A company like...

Intel
Intel, which sponsored the International Science and Engineering Fair, and awarded Khare her $50,000 prize, has been trying to break into the mobile computing market for some time now. The fact that most investment news stories on Khare's invention are focusing on the "time to recharge a cell phone" angle suggests this is the first tech improvement we should look at. If Intel is able to secure rights to develop and scale up Khare's invention, it could simply dominate the market for electricity-hungry cell phones, tablets, and notebook PCs.

5. See this line? "Hold this power longer without going "dead"?

Seems to contradict the "it leaks!" "this is no big deal!" comments.


Anyway...

6. Yeah

I didn't get back to this one, but apparently it is a big deal. Now I have to go find the links again.

I dropped my work hours to eighty percent, so hopefully Ivan be more consistent with my life

3. 10-15 years ago I bought them in Radio Shack...

thought we had a great new "battery" for another gadget we were making until we realized, as you said, the charge just doesn't last. Voltage and current are tough to control, too, if you have sensitive parts. Made a great bug zapper, though.

But something's missing. Intel should know a lot more than we do about capacitors, but gave her a prize for this? Maybe it's more than it looks like. (Or maybe the other entries were more lame...)

4. I looked at a couple of sources on this

They seemed to think it was a big deal. Or at least, a deal. I'm not an IT person, whatsoever. but overall, it sounds like a nice accomplishment for an 18 year old woman.

I'll go check a few more tech sources. Or ask the tech people at work who know what they're talking about.
