LOS ANGELES — Determined to uproot contemporary opinion, General Motors designers have branched out and created an award-winning HUMMER 2-dimensional concept that not only looks like a tree, it acts like one. The vehicle was created through the use of modelling software, so it is not an actual vehicle, but could likely be built within a year if the green light were to be given by General Motors.

With the HUMMER O2 Concept, GM's Advanced Design studio in Los Angeles makes the case that daily use of an automobile can go farther than just being environmentally friendly – it can actually help the environment.

The HUMMER O2 is GM's answer to the 2007 Los Angeles Auto Show Design Challenge, which for the third consecutive year, asked automakers to offer a vision of the future. Los Angeles is home to one of the world's greatest concentrations of automobile manufacturer design studios and for 2007, eight automakers competed on the Design Challenge theme of Environmental Sustainability. The HUMMER O2 took home the top prize.

The Los Angeles Auto Show Design Challenge challenges manufacturers' Los Angeles-based design studios to explore new ideas in automotive design. This year, studios were challenged to imagine a time when all vehicles have "green" technology allowing drivers to enjoy the Southern California environment without harming it.

Entries were judged by multi-discipline design professionals who selected the winner for its originality of creative concept, contribution to the environment, degree of safety and reflection of a unique, spirited California "green" lifestyle.

"We were overwhelmed by the depth of imagination and creative thinking these top design studios created for this year's challenge," said Chuck Pelly, director of Design Los Angeles and partner in The Design Academy. "Hummer 02 was chosen because of the wide-range of known technologies included, but with an imaginative twist, such as the tread "light" tire technology."

At General Motors' West Coast Advanced Design Studio in southern California, designers posed the most far-reaching question of all – can daily use of a vehicle result in a "net gain" for the environment. Their answer, after eight months of research and careful designing, was "Yes!"

The HUMMER O2 Concept looks like a tree, with manufactured leaves and a trunk, and acts like a tree by working on the principle of photosynthesis – it takes in carbon dioxide from the air and emits oxygen.

The revolutionary bodyshell produces pure oxygen (O2) throughout the life of the vehicle. It generates that oxygen from a canopy of aluminum-framed, clear plastic panels holding algae cultivation that use carbon dioxide (CO2). A 2-way valve system in the corner of each panel monitors and controls the amount of carbon dioxide and source nutrition needed for the algae cultivation while optimizing oxygen production and distribution.

The bioreactor panels would, of course, be made from recycled materials, and would hold the algae biomass in a preserved environment, so the water wouldn't slosh around as the vehicle travels.

"We started out looking at a vehicle that would be environmentally neutral, but looked beyond it toward creating a vehicle that would have a 'Net Gain' for the environment," explains Steven Anderson, Manager of Concept Development and Design Strategy. "We started with a hydrogen fuel-cell vehicle which is neutral to the environment and then developed the idea of taking the carbon dioxide that all these cars are putting out and turning it into oxygen."

The HUMMER O2's power source is hydrogen, an environment-neutral power source. Four modular and self-contained fuel cells power hydraulic motors built into each wheel. A hydrogen tank is placed in an ideal central location for safety and structural purposes, becoming the "heart" of the vehicle.

An added benefit came to light after a recent study at University of California - Berkeley, which found that certain algae actually produce hydrogen. That brings up the possibility that the vehicle may actually be able to power itself, in effect becoming almost a living entity.

"The HUMMER O2 epitomizes the ethos of the true Southern California outdoors enthusiast with rugged capability, a 'tread lightly' contact system and construction methods promoting safety, accessibility and re-usabilty," said Frank Saucedo, director of GM Advanced Design, California. "Most vehicles in LA spend 95 percent of their time outdoors, so why couldn't a vehicle give back."

Other features on the HUMMER O2 are Active Tread tires that provide low rolling resistance on the highway, but allow excellent off-road progress as their shapes change to adapt to terrain, in effect also protecting the surrounding environment.

The HUMMER O2 is made entirely from 100-percent post-consumer materials, including the aluminum frame, seats finished with materials that are free of Volatile Organic Components (VOC) and glazing that is similar to everyday consumer packaging, such as soda bottles.
