Hi. A software-bot removed your comment from the Sailing_faster_than_the_wind article. Wikipedia isn't really a place to discuss this stuff, but I'll point you to our Blackbird (land yacht) article. It's possible, and it has been done. If you check the links on that article you'll find it's thoroughly documented. Sailing directly downwind faster than the wind is indeed the same as sailing upstream on a calm day. I know it sounds impossible, but the Blackbird (land yacht) article proves that this has been achieved on land, and it include a links to the physics analysis preformed by an MIT professor Mark Drela, expert in Aerodynamics and Computational Fluid Dynamics. The super-short explanation is that the difference in speed between the land and the air (or a stream and the air) constitutes a power source. It doesn't matter which one is moving, as long as there is a difference in speeds you could set up a windwill and collect power. So a power source exists. That power source does not cease to exist just because the vehicle happens to move. Tapping into that power source while moving is a weird engineering problem, but it doesn't violate any laws of physics. Once you do tap into that power source then vehicle can use that power to move in any direction. Alsee (talk) 18:33, 21 November 2014 (UTC)
