The Intel International Science and Engineering Fair is the “world’s largest high school research competition,” and is owned and administered by the Society for Science & the Public. It was founded in 1950 by Science Service (now the Society for Science & the Public) and has been sponsored by the Intel Corporation since 1997. Each May this event is organised and about 1,600 finalists are selected annually from hundreds of affiliated fairs in 70 countries, regions and territories. The participants compete for scholarships, tuition grants, internships, scientific field trips and the grand prize of winning one $75,000 or two $50,000 college scholarships.

This year, the Intel International Science and Engineering Fair was conducted in Phoenix, Ariz. Eesha Khare, from Saratoga, California was one of the participants in this event. She invented a new black colored, over an inch long rectangular type supercapacitor that fits inside mobile phone batteries, and could allow the batteries to charge within 20 to 30 seconds. According to Khare, the device can last for 10,000 charge-recharge cycles, compared with 1,000 cycles for conventional rechargeable batteries.

Khare said, “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 also said that the technology might also “speed up charging of automobile batteries.”

Khare’s invention was honored as one of two winners of Young Scientist Awards by Intel Foundation. She won $50,000 prize money. Khare said, “I’m in a daze. I can’t believe this happened.”

This major science award will help Khare fund her college education at Harvard University. The $50,000 prize money will be delivered to Khare when she heads to Harvard University in the fall.
