I have very serious doubts about the efficacy of wind powered anything on Mars. For all practical purposes , as far as humans are concerned,The surface of Mars is outer space.The average surface pressure on Mars is .087 psi. Around an earth altitude of 24 miles or so. If you see the videos of Felix Baumgartner leaving his balloon gondola ~128,000 feet , you'll notice no wind resistance of any kind on his SPACE suit. Not even the slightest flutter.. see for yourself1
