I am not sure I understand what you are suggesting. Does the piston return to its beginning point with each cycle? If so, at least a complete loop is covered which is the requirement.

It occurs to me now that we may have made a simple problem into a difficult one. Our initial challenge is to find out whether the Papp mechanism is overunity by an obvious amount; ie, the effect is not a threshold one. We can start out with a simple popper hooked up to a flywheel like the one seen in Puppy Dog's video, where there is an arm that moves the wheel in only one direction. Now attach a chain to the wheel and use it to draw a sled with known weight across a surface of known friction with the sled. Energy in would be the integral over time of the power used to drive the system. Energy out would be a function of the distance the sled moved. Heating due to friction would be ignored to obtain a pessimistic lower bound. A two cylinder engine could be used in place of the popper if such an engine is available. Eric
