If you've been thinking, "you know what I need? A HUMMER snowmobile," your answer is sitting on the expo floor at SEMA 2008 in Las Vegas today. Zero South created this biodiesel-powered, Antartic "truck thing" that has tracks instead of wheels, according to AutoblogGreen. But that's nothing until you find out who will be driving it.

That's right, none other than Apollo astronaut Buzz Aldrin and Apple co-founder Steve Wozniak are set to pilot this thing in a South Pole expedition in 2009 called Drive Around the World, the report said. I'm not making this up. Chris Paine, the director behind the documentary, "Who Killed the Electric Car?" will be filming the entire expedition in 3-D.

Even more insanity: The vehicle runs on B99 and can do 35 mph in a pinch, but they're going to keep it at 15 mph during the Drive Around the World. "The plan has actually been modified recently and it is said Jay Leno will be helping to install a VW diesel four-cylinder engine to act as a generator for four electric motors powering each track cluster," the report said. What a riot!
