Another model demonstrating the principle of the cart that moves down wind faster than the wind. Inspired by some ideas posted on the discussion at forums.randi.org, I made a simple cart that is propelled underneath a moving surface, faster than that surface. The large wheel, turning against the direction of movement of the ruler, is very similar to the propeller of the wind-powered cart, turning against the wind.

PS. Several people have asked where Louise comes from. She was made in Sri Lanka for Barefoot: http://www.barefootusa.com/NewFiles/t...
