While most of the world is cutting down on fuel consumption through driving less, carpooling, riding public transport, or waiting for the next hybrid to be available, Jennifer Garner has gone to the next level. We spotted the "Juno" star driving a new BMW Hydrogen 7 which instead of traditional gasoline is fueled by hydrogen.

But don't expect to run out and buy your hydrogen fueled car, BMW is currently the only company producing a street legal version and it is presumed that there are only about 100 of them in the United States, mostly driven by celebrities and other high profile people. But if they catch on, BMW is hoping to move them into mass production.
