Extreme “Green” Hummer: The Hummer O2

Later this month at the L.A. Auto Show nine California-based car design teams will showcase their ideas for earth-friendly cars of the future. The contest required auto-designers to submit designs and sketches of vehicles that would be fully recyclable after 5 years and have as little impact on the environment as possible. The Hummer O2 concept has algae-filled panels that make up the sides of the vehicle. The cells would turn C02 into Oxygen, just like a plant does, to power the car. When the car is parked the side panels spread out to maximize this effect. I wonder how it does off-road?
