It doesnt....not true but close if you mention efficiency. A paddlewheel will convert less than 10% of combustion energy...They are fun. I live in Louisville KY and have been on the Bell of Lou and the Cincinnati Queen many times.
Our horses are much more efficient and often more fun!!

The paddle wheel works like a series of oars. The engine transfers the linear piston motion to an eccentric arm attached to the side of the paddle wheel, causing it to turn (the same way the old steam railway locomotive drive worked). The axle of the wheel is attached to the boat. Contrary to what you might think, however, the wheel acts like a second class lever with each paddle as it hits the water. The water is the fulcrum, the axle attachment is the point where the load (the boat) acts, and the effort (on the eccentric arm) is at the other end of the lever. (You are not trying to push the water backward, you are trying to push the boat forward.)
