Pepetual motion as a source of free energy is a joke. Why people believe it is beyond me. Examples of "Gravity motors", not waterwheels but "Gravity motors," operate without a load and stop when a load is applied. Air friction is itself a load which slows "Gravity motors". Free energy enthusiasts should at some point realize that their inventions cannot emit more energy than is contained in the closed system of their gravity motor and any starting energy. Also, any noise from the gravity motor is a source of energy loss and gravity motors are apparently noisy. JMG.
