UC Irvine students Kyle Good and Bryan Le have come with the next X PRIZE challenge: build an ultracapacitor. The pair won the X PRIZE Foundation’s “What’s Your Crazy Green Idea” contest, which asked entrants to post a 2 minute video describing a concept for an X PRIZE in the Energy and Environment category. Le and Good won $25,000 for their idea. The winning video is below.
