To the depths of the Earth … and beyond! Watch Bill Stone on TED.com

Bill Stone, the maverick cave explorer and diver — who has invented robots and rebreathing equipment to let him plumb Earth’s deepest abysses — talks about his efforts to build a robot to explore Jupiter’s moon Europa. The plan is to send the droid to bore through miles of ice and swim through a liquid underworld that may harbor alien life. And if that’s not enough, he’s also planning to mine ice, on Earth’s own moon, by 2015. (Recorded March 2007 in Monterey, CA. Duration: 17:55) Read more about Bill Stone on TED.com.
