Ben Saunders is one of these guys who like to go skiing in the Arctic. He already did some really impressive stuff including a solo expedition to the North Pole. The cool thing is that on this trip he was constantly blogging using custom software and a satellite phone. Ben also sent the first live video ever from the North Pole.

At the moment he is in Greenland testing new equipment and so far it is really interesting to follow his "daily-routine". Btw ITConversations has a podcast with Ben where he talks about his expeditions and what motivates him to do this kind of stuff. Highly enjoyable.
