DDWFTTW - Demonstration of Flawed Design Posted by: spork33
Video duration: 168 seconds Global video hits: 779 In this video we demonstrate a design proposed by one of the participants of the many on-line discussions of DDWFTTW. While there are aspects of the design that we have used ourselves to illustrate the theoretical possibility of DDWFTTW, this design lacks dynamically feathering vanes, and therefore cannot achieve DDWFTTW Related: ddwfttw, downwind, dwfttw, fail |

Direct Downwind Faster Than the Wind #2 (DDWFTTW) Posted by: spork33
Video duration: 49 seconds Global video hits: 2214 JB shamelessly stole MarkC's design and had to try it for himself. This really does make a slick little cart that nicely shows that it is possible to make a simple wind powered vehicle that goes downwind faster than the wind. Related: ddwfttw, dwfttw |

DDFTTW - Directly Downwind Faster Than The Wind Posted by: VideoJunkie666
Video duration: 79 seconds Global video hits: 2545 Demonstration of a cart going directly downwind faster than the wind. If the cart moves foward on a 10mph treadmill in a windless room then it can go faster than the wind directly downwind. Mark C.

DDWFTTW_Analogy.wmv Posted by: RickWilloughby
Video duration: 13 seconds Global video hits: 925 This clip is intended to demonstrate why DDWFTTW sailing is possible. The upper wheels acting on the moving surface mimic the operation of the propeller and the lower wheels on the table mimc the water turbine. The system is possible by virtue of simple gearing. Notice how the vehicle can actually move faster than the board that is forcing it along. Related: ddwfttw, down, faster, sailing, than, wind |

Under the ruler 2: the ground moves Posted by: coolaun
Video duration: 232 seconds Global video hits: 3459 Why do people test a wind-powered cart on a treadmill? Wind is the relative movement between air and something else (usually the ground). We usually think of the ground being stationary and the air moving, but it works just as well to have the air stationary and the ground moving.
