Steve Wozniak to Drive Hydrogen Hummer to South Pole, Cult of Mac Blog
"Woz explained that he was participating in an expedition planned for December 2007 in which a group will drive Hummers running on hydrogen powered fuel cells from McMurdo Station to the South Pole. Woz said his particular vehicle would be co-piloted by Buzz Aldrin, who walked on the moon in 1969. The expedition is to be filmed in 3D for the director James Cameron."
Editor's note: This strikes me as a Reality TV version of those "I'm a Mac/I'm a PC" commercials.
