She won the $50,000 Intel Foundation Young Scientist Award

A high school student from California has created a way to charge cell phones completely in just 20-30 seconds. 

Eesha Khare, 18, of Saratoga, California, recently won the $50,000 Intel Foundation Young Scientist Award for her fast-charging device. 

The device uses an improved supercapacitor that can store a lot of energy into a small space using a nanorod electrode. It is capable of 10,000 charge-recharge cycles and can fully charge a cell phone in 20-30 seconds. 

Traditional chargers typically take hours to achieve a full charge, and are capable of only 1,000 cycles for rechargeable batteries.


Khare said her supercapacitor has been used to power an LED, and sees her invention being placed in cell phones in the future.

"It is also flexible, so it can be used in rollup displays and clothing and fabric," Khare said. "It has a lot of different applications and advantages over batteries in that sense."

This definitely isn't the first time a high school student has come up with a brilliant invention in recent years. Just last year, 15-year-old Jack Andraka invented a new pancreatic cancer test that earned him the $75,000 prize from another Intel-sponsored fair.

My phone's battery is 3.7 volts and 1700 mAH (1.7 amp/hr) and it normally charges at 0.5 amps, or about 3.4 hours to a full charge.

To charge this in 20 seconds, we would need to apply ~300 amps of DC current - not going to happen, even if you put a capacitor between the charger and battery. Even if the battery OR capacitor could handle that much current, you would still need to apply ridiculously high current to charge it in a space of 20-30 seconds.

Pretty much this. Liberals' idea of diversity - anyone who's not a white, American male.

The winner actually is the only person that fits the white male description.

I hope at this point you realize that I had to make this account just to come reply to each of your posts. It was bothering me that you thought you were qualified to have any say here. Everyone else has posted 50 line comments with quotes from other articles backing up their statements. You just wait for them to say something and then say "NO". It is so funny to me that you would think anyone is reading your comments and agreeing with you. LOL. You are an idiot.

SHE DID NOT CHARGE A CELL PHONE IN 30 SECONDS. She lit an LED with a capacitor. I could literally make a capacitor and an led from shit laying around my house and light it up. You feel trapped because you simply cannot engage in intellectual conversations. Your posts are severely lacking. Being in the same world as people like you is the real problem. People who think they are intelligent and know what's going on, when really you just got spun around 5 times and tried to put your fingers on the keyboard like some weird version of pin the tail on the donkey.

You're right, it only takes you 5 lines to be a troll
