One the first posts here at complementary slackness was on the apparent phenomenon of a machine that can go downwind faster than the wind (DWFTTW). Now it’s been convincingly demonstrated by Rick Cavallaro and co at fasterthanthewind.org and verified by the North American Land Sailing Association that DWFTTW is possible; their cart traveled directly downwind at 2.8 times the wind speed.
Does anyone know of scientific articles on this phenomenon?
[Edit: after further thought, my earlier arguments on how it might work don't seem to have been "windicated". So I updated the post DWFTTW accordingly.]
