WingMill as Polar Energy Wind Tech

WingMills are fabric sails that flap powerfully and might be the best way to make power at a stationary WindSled Encampments. As you can see in the video linked below, they do not need a tower, just a post, nor the same attention a kite might need, and they would passively de-ice. Marco can see that the pumping motion could drive the same generator that a moving WindSled might use, but its a faster shorter stroke, unless the wing is big. Sailors have been killed by large "flogging" sails, as any powerful mechanism can be dangerous.

This is obviously a good contender to power remote Polar communities in the winter, with a far lower capital cost and easier set-up than a wind tower. A big problem with Polar wind-towers is accessing the top to de-ice or make repairs in bad conditions. WingMills can also be carried high under Lifter Kites, but open Polar terrain has good wind at the surface for WingMills. This Wind Tech was also exciting to Italian Antarctic scientists in 2011, whose contact info I need to relocate. Its also easy to fabricate and repair by sewing machine. In fact, large WindSleds should perhaps carry sewing machines.

Confirming that Lion Batteries hate cold, as my electric skateboard enters the cold season with weaker power. They are still usable at lower power, but a multi-battery basis and/or thermal (hot-water) reservoir strategy needs to be worked out in practice. It would help to know what WindSled's current battery specifications are, to work forward from there.
