Designing the Paddlewheel

Our dear friend Robert has worked the math on the wheel structure and supplied us with a hypothetical drawing.  Paddlewheel math is really interesting.  Here's a version:

The basic calculation is this:  The size of the paddles is the wetted surface of the hull (excluding rudder surfaces) divided by the average rpm of the wheel, with the velocity at any given speed calculated as the number of times the circumference of the wheel will play out as distance. So a 10' wheel will travel 100' for every ten revolutions.

Cool, hunh?

More shortly...Just wanted to share this.

indiegogo campaign still going Here.  Lend us a hand building this.
