Page 1 of 1 General Motors' West Coast Advanced Design Studio in southern California produced this entry, the HUMMER O2 Concept, for the 2006 California Design Challenge contest whose theme this year is Environmental Sustainability. The HUMMER O2 two-dimensional Blue Sky Concept offers rugged capability, a 'tread lightly' contact system and construction methods promoting safety, accessibility and re-usability. For example, the HUMMER 02 Concept features a revolutionary phototropic body shell that produces pure oxygen throughout the lifespan of the vehicle. Algae-filled body panels transform harmful carbon dioxide into pure oxygen that is subsequently released back into the environment and inside the vehicle. Four modular and self-contained fuel cells power hydraulic motors are built into each wheel, and to reduce environmental impact, the HUMMER O2's construction utilizes 100 percent post-consumer materials. The contest winner will be announced at the Los Angeles International Auto Show Thursday, November 30, 2006. GM won the competition last year. Page 1 of 1
