Hummer isn't exactly the first auto company to come to mind when one thinks of environmental friendly vehicles, but it looks like they're trying to change that. This concept vehicle that they showed off at the LA Auto Show is called the Hummer O2, and it actually makes its own oxygen. It's got algae growing in the side panels, using photosynthesis to give you stuff to breathe while you drive. It's like driving in the middle of a swamp! Isn't that cool?!
It's a nice idea and all, but it's pretty obvious that this isn't gonna be hitting the road anytime soon and I sure don't think the H2 is getting discontinued, so this looks to be like just a lot of hot air. Nice try, Hummer.
