Works in theory! Practice? That's something else
See post #20 for my mental evolution regarding the cart mechanics.The propeller blades of this cart also have apparent wind
Nice set of Newtonian-style vector drawings!...I rejected their cute illustration of two sailboats on a cylindrical world as a propellor because sailboats on a broad reach still have an apparent windspeed....
But, I still reject the illustration they used for the reason mentioned, if there's no wind on a boat sail, there can be no force. When the apparent wind is zero, the force is zero. For example, a free-spinning wind turbine mounted on a truck will not spin when the truck speed is moving at the same speed as the wind.
