Fridtjof Nansen, the ship "Fram" in the ice, a dog sledding.

Additional:

Fridtjof Wedel-Jarlsberg Nansen (October 10, 1861 - May 13, 1930) - Norwegian polar explorer, scientist - doctor of Zoology, founder of a new science - physical oceanography, politician and public figure, humanist, philanthropist, laureate Noob Peace Prize for 1922, awarded the awards of many countries, including Russia. Name Nansen named geographical and astronomical objects.

One of Nansen’s most important voyages was the Norwegian polar expedition on the ship "Fram".The expedition proved that there is no land near the North Pole, instead establishing the existence of an ocean basin. Nansen discovered that the Coriolis force due to the rotation of the Earth plays a huge role in the drift of pack ice. Based on an analysis of the results of the expedition in 1902, Nansen deduced two simple rules describing the speed and direction of ice drift, known as the "Nansen Rules" and which received wide practical application in polar expeditions of the 20th century. In addition, Nansen for the first time described in detail the process of growth and melting of pack ice, and also described the phenomenon of “dead water”.

For polar explorers and athletes, Nansen's technological discoveries play a huge role. He was the first to use the experience of Eskimo survival on a large scale, and a number of his inventions (light bamboo sledges with metal runners and a device for cooking food and the simultaneous kindling of drinking ice with an efficiency of 90%) are still used.

One of the remarkable technical details of the Fram vessel structure was a wind turbine with an electric generator.

It quickly fell into disrepair due to weather conditions.

That is why on the stamp you can only consider the frame of the wings of a generator.

In the photo provided by Wikipedia, you can easily and well see the electric generator wings.
