GM contemplates the living, breathing Hummer

GM's sketch for the "Hummer O2" was named the winner on Thursday of a design contest at the Los Angeles Auto Show that challenged major automakers to design a vehicle with a five-year life span that could be fully recycled.

The GM vision for the futuristic Hummer concept includes an algae-filled body shell, designed to shed oxygen, that also opens up like leaves on a stem to catch sunlight when parked.
