Think you can capture greenhouse gases? Can you explain how quantum solar cells might work? Looking for an excuse to put together a homemade fuel cell or a water bottle desalinator? All you tinkerers, tree huggers, and students with lab kits can share your ideas with the world and win hundred of dollars in prizes by entering DISCOVER and Instructables.com's Science Fair For a Better Planet.

To enter, take your planet-saving ideas to the lab (some people call it a "garage") and then publish your detailed build or experiment online at instructables.com. Your mission could be building a new or improved green product (like a wind-power device without the turbine or a bike/generator) or documenting an experiment that deals with climate change and sustainable living (like finding out how biodegradable different products are). But that's just a tiny slice of what's possible.

For more detailed instructions, check the contest's page on Instructables.com.
