Father and son trek to South Pole, using only renewable energy

Father and son trek to South Pole, using only renewable energy


a person riding a snowboard down a snow covered slope: Robert and Barney Swan towing sleds topped with solar panels across Antarctica. 
Thirty-two years ago, Robert Swan made history as the first person to walk to both poles. Even as a young man, these grueling expeditions took a harsh toll on his body. Passing directly beneath the hole in the ozone layer, Swan's face became badly burned and his eyes even changed color. But the Arctic explorer now says that all of that physical duress pales in comparison to the agony of watching his son go through the same experience 32 years later.

This past winter, after years of preparation, Robert Swan set out to trek the 600 miles to the South Pole again -- this time, with his 24-year-old son Barney by his side. And this time, with an additional challenge built in: they would survive exclusively off of renewable energy.

It was a "swan song" with a very important goal. If the father-son team could get by on renewable energy in the harshest environment on Earth, then people in the comfort of their own homes could do it, too.

"At the age of 61, it's not really something that people should do," Swan told CBSN Originals of his decision to undertake the difficult journey across Antarctica a second time. "But Barney convinced me that together as father and son, together as the millennial generation and the older generation, we need to join together because this can't be a bunch of young people thinking one thing and a bunch of old people thinking another. We've got to join together because we are in a survival situation on planet Earth."

The success of the expedition necessitated the pioneering of new equipment that would use renewable energy to melt snow and ice into hot water on the move in the Antarctic. So, while Robert had previously used jet fuel to cook his food and keep warm in the -40-degree temperatures, this time he and his son used biofuels derived from wood chips to do the job. They used solar panels, provided by NASA, that plugged into their sleds to melt ice and snow into drinkable water.

"We're attempting to do something that no other expedition has tried yet in the hope to really show that these technologies can work, not only in our own nations, in our own homes, but in the world's most hostile place," Barney explains in the CBSN Originals documentary, "Expedition Antarctica," as he and his father are preparing to set off on their unprecedented journey.

While the energy sources sustaining them were different, Antarctica's climate was as unforgiving as ever. And once again, the combination of subzero temperatures and strenuous physical activity began taking a harsh toll on Robert's body.

"His legs, his inner thigh, everywhere in between, it was like repellent," Barney recalled to CBS News. "We're talking like bits of flesh falling off him. He was decaying. And to think that all it takes is that one degree too far and you could die; I was literally watching my father on the slow road to death."

Robert finally realized that in order for the expedition to succeed he would have to bow out. The team had to keep up its pace or risk running out of food and fuel; slowing down or waiting until he recovered weren't options. So he made arrangements for a helicopter to transport him back to base camp, and he made the excruciating decision to leave Barney behind to finish what they'd started.

"It was the worst moment of my life for the simple reason that I knew what lay ahead," Robert recalled through tears in an interview at Davos. "I felt a failure as an expedition leader. I felt a failure for my son. I felt absolutely appalling, but I knew that this expedition wasn't about Robert Swan. This expedition was about inspiring people on energy use. It was about doing the right thing and the right thing for me to do was to put myself second and the expedition first. I just had to, for once in my life, realize my limitations. And I went back to the base camp and had the worst week of my life, dealing with the word failure. And I had to listen to what was happening with my son's feet. His toes were turning black. ... And I was sitting there thinking, 'I should be there.'"

Father and son explorers Robert and Barney Swan discuss their mission to save the planetBarney, however, didn't see his father's decision as a failure. On the contrary, the 24-year-old, whose toe was turning black due to the brutal negative-40-degree temperatures and repeated banging on his boots, was overcome with pride for his dad.

"I don't think I've ever been as proud of my dad," an emotional Barney told CBS News. "It takes courage to tell your team you don't have it in you, and that's what he did today."

Barney, more determined than ever, continued on toward the south geographic pole. And when he was 60 miles from the goal, Robert choppered back in to join him, so that together, they could complete their mission.

"It was a moment where I let go of so many things in life because he'd done it," Robert recalled, looking lovingly at his son. "Those stupid words like 'failure' and everything else disappeared because there he was in my arms."

Now, father and son have both inked their names in the history books. They've risked their lives to send a dramatic message to the rest of the world about the feasibility of climate solutions. And they've proven that a passion for adventure, innovation and discovery just may be something that's passed along, from generation to generation.

"The last thing I said to Barney as I got on that plane," says an emotional Robert Swan, "[was] just remember whose son you are. And my blood's in your blood. And you can bloody do this.' And to do it, he had to go through hell and he's still going through hell, but we did it."
