Micah, Chris and Nobu - three guys passionate about the green life - take a veggie-fueled trip across America in search of amazing eco-inventions. Their journey takes them from New York to California, while they seek out the grassroots green inventors.

Invention Nation gives you an inside look into the lives of these inventors to learn why they took "going green" into their own hands. What was the green problem that had to be solved? How were their contraptions built? What tools did they use? How can anyone get by without duct tape?

Whether it's road-testing a human-powered car, assembling a solar panel from used CDs, or building a homemade windmill, the MacGyver-esque designs range from simple to unreal. And between visits the guys hang with the inventors; negotiate their way into roadside diner kitchens for used grease to fuel their bus; and generally inspire the people they meet along the way to get a little greener. Invention Nation shows that people really are helping save the planet, one invention at a time.
