I never thought I'd be praising the eco-savviness of anything named "Hummer", but the Hummer 02 converts carbon dioxide into oxygen using algae-filled side panels. Since the algae are getting a megadose of sunlight (where they're usually submerged underwater) they get to work overtime kicking out the good stuff. It also looks kind of like a lunar landing dune buggy, where you would want all the extra O2 you could get. Eat your heart out, portable oxygen bar - now my oxygen ports me. [GT]
