Brilliant teen creates device that charges cell in 30 seconds!

Eesha Khare

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!

    Winning the Intel science fair is usually a good sign of a first class technical or scientific intellect, so I’m confident that Ms. Khare would like it if people got the details correct, unlike basically every pop science article written about her that I can find:

    She did not “invent a fast-charging device called a supercapacitor”. Supercapacitors have been around for decades. Worldwide sales in 2010 were about $400 million.

    She did not create a device that charges cell phones. Her supercapacitor only powered a single LED, as a proof of concept.

    She came up with an idea for a new type or variation of supercapacitor with a higher energy density and demonstrated it in action. That’s impressive enough! These over-hyping pop science articles not only obfuscate the real nature of scientific and technical progress, but they are disrespectful towards Ms. Khare’s actual achievement.

      Here’s her actual project summary. It sounds like the energy density is still about 4 times most capacitors currently in use, but still about a factor of 10 below lithium-ion batteries (which are mostly what we are actually currently using in our phones). It looks like people are currently more enthusiastic about the upcoming generation of graphene supercapacitors, which have even higher energy densities as measured in the lab, but still a pretty nice technical achievement on Ms. Khare’s part.
