Down wind faster than the wind. I only heard of this today. It describes a machine that can travel down wind faster than the wind that is powering it. Here are some videos that got me looking at the idea. http://www.youtube.com/watch?v=xHsXcHoJu-A a car that uses its wheels to turn a propeller. http://boingboing.net/2008/12/12/downwind-faster-than-1.html A different device that seems to work on the same principals. What do you make of this? Do you beleive it is real? Can you explain how it works? I have read a few different articles on such devices, and none (whether they say it will work or not) have convinced me. But I am leaned towards them working. A google search for "Down wind faster than the wind" or "dwfttw" will bring up a lot of sites addressing these devices.
