The vehicular trips to Pole keep getting fancier, but this one is somewhat unique. The Korea 2010 Green Expedition set out to cross the continent from Hercules Inlet to Terra Nova Bay using snowmobiles powered only by solar and wind energy! This venture was led by 47-year-old Park Young Seok...the experienced mountaineer who happens to be the first person to complete what is known as the "Adventure Grand Slam"--the Seven Summits, the 14 8000ers, and both Poles (Park was the leader of a 5-person Korean team that traveled unsupported to Pole in 2003-04) (archive page).
The 6-person team, consisting of Mr. Park, Kang Seong Kyu, Kim Soo Hoon, Shin Dong Min, Lee Yong Tack, and Lee Yong Mook started from Union Glacier on 19 December, they first headed north to Hercules Inlet, the official start of the expedition. The two snowmobiles were specially engineered by the expedition sponsor, SBS (Seoul Broadcasting System); each had a 5KW electric motor and was capable of speeds up to 12 mph.
The two snowmobiles relied on a total of 24 210-watt solar panels and four 400-watt wind turbines. Since this equipment obviously could not be deployed while the team was on the move, they had to stop each time they needed to recharge the batteries. Under normal conditions they traveled 35 miles per day, in two separate charging/driving sessions. But overcast/whiteout conditions with no wind often made charging impossible.

I note that there appear to be four 8-cell battery packs in this photo...and also that there is no insulation on the box. Oh well, my Korean isn't very good, I'm afraid, but all of the equipment details are on this page of the expedition web site.|
In mid-January, with the ALE/ANI scheduled closure of Union Glacier getting close, the expedition decided to split up...Lee Yong Mook and Shin Dong Min were left behind at about 86°S. They were evacuated along with one of the snowmobiles and some of the equipment. The remaining four members of the team pushed on, running short of food and water, and arrived at Pole in the evening of 28 January SP time, as seen below.
