Green X Prize Challenge to Focus on Advanced Energy Storage

Published February 05, 2009

A winner has been chosen from the 133 entries in the X Prize Foundation's "What's Your Crazy Green Idea?" competition to determine the focus of an X Prize energy and environment challenge.

UC Irvine students Kyle Good and Bryan Le won $25,000 for their entry, The Capacitor Challenge, which asks entrants to develop an advanced ultracapacitor, an energy storage device more powerful, more affordable and more environmentally-friendly than current battery technology. Capacitors can recharge quickly numerous times, but are expensive.

The proposed competition would seek real, working energy storage devices that exceed the energy density of an average lead acid battery, recharge in less than a minute, recharge up to 500,000 cycles, are recyclable, contain only non-toxic materials and cost less than two times the price of an average lead acid battery.

The device would also have to be able to power an electric vehicle for 100 miles, recharge and drive it back the same distance.

The YouTube-based "What's Your Crazy Green Idea?" competition, sponsored by Prize Capital, accepted two-minute video submissions describing possible X Prize contests focused on energy and the environment. Out of 133 entries, three finalists were selected and voted on, garnering more than 4,200 votes altogether.
