There is only 1 day left to Participate!, TreeHugger and Current TV's contest to get you - and your best eco-idea - to Burning Man. As a part of this year's theme, "The Green Man", Burning Man is looking for the best open-source ideas to help green the way we live, eat, drive, build, etc. So, what's your best open-source idea? Send it to: contest [at] treehugger [dot] com by 11:59pm EST tomorrow, August 11th, and you could win 2 tickets to Burning Man, the Burning Book, and a chance to be featured on Current TV's "TV Free Burning Man" coverage of the event. But, we do need to see what you are working on, so be sure to send us a 3D (preferable) or 2D image with your idea. Now, go Participate!
