Got a Great Green Idea?

There is a new contest being sponsored by the folks that run the X Prize. Submit a video to YouTube of your best/most creative/craziest green idea and maybe win $25,000.
Here are the basic rules:

1. Submit a 2 minute video to this group by October 31, 2008 explaining what you think should be the next Energy and Environment X PRIZE: http://www.youtube.com/groups_addvide...
2. We'll post the three most viable ideas to http://www.xprize.org on November 15.
3. The public will be given two weeks to vote for the winner on http://www.xprize.org
The most creative, revolutionary idea and video will receive $25,000 and could become the next great X PRIZE!

Be sure that your video answers the following questions:

1. What is the Grand Challenge or world-wide problem that you are trying to solve?
2. What is the specific prize idea (goal, rules, judging criteria)?
3. How will this prize lead to benefits for humanity?
