Transantartika is a sportive even, a tough adventure of three excellent climbers to conquer the south pole in a low carbon way. They celebrate the 100 anniversary of the Amundsen and Scott race for the south pole going with skies and kites. They are going really fast in some days driven by the wind. It would have been wonderful for Scott to have such a resource. It is not the only renewable energy they are using, they also power their electronics with solar panels.
It is interesting to see how related is the power of wind or other renewables with sport evens (also for sailings for example, or bicycles) and how far is from more common and everyday transport options. I know it is not the same, but it has to be quite reliable if they are risking their lives in Antantica. It is curious but Scott, who died in his expedition was a pioneer in using motorized sleights and nowadays with all the possible technology the wind has been chosen. Of course the technology has evolved a lot for the motors, for the materials and for the kites too, fortunately.
One final thought, will it be so interesting to do this in some decades? The temperatures may have risen noticeably although it could be even more unpredictable due to climate extreme events.
