A Korean expedition team looking to trek across Antarctica using solar-powered snowmobiles has run into trouble as unseasonably humid weather leaves the usually sunny and clear summer skies overcast and dull.
The expedition, led by veteran mountaineer Park Young-seok, set off from Antarctica’s Patriot Hill in late December on a 1,056km journey to the South Pole, but the from the beginning the team has been beset by difficulties, not least of which is heavy cloud cover – part of the massive storm system causing record rainfall on the Australian mainland – which dumped more snow than the region has seen in 20 years.
The initial idea was to utilise Antarctica’s "endless summer," in which the sun never fully sets from November through until February, a major bonus when running heavy machinery with solar power. But the team’s best laid plans played second fiddle to the weather gods and Antarctica’s white night never eventuated, leaving the team 330km from their destination. Unless they can reach the South Pole by Sunday, they will have to abandon solar-powered sledding and fill their snowmobiles with gasoline to make it back to base camp.
This solar energy-blocking cloud greatly impacted the portable solar recharging equipment for the team’s eco-friendly snowmobiles and other camp equipment for much of the time. The solar recharging stations use high-efficiency SunPower solar panels. In full sun they can provide enough power for a three hour drive from a nine hour charge.
Park’s expedition will be made into a documentary for the Seoul Broadcasting System as part of its 21st anniversary year celebrations. They hope the trip will raise the profile of solar energy use in Korea and around the world.
