Just for grins and giggles. If you took the the pmg out of mill axle, and put a 15" pulley connected to 3" pulley, a 5 to one racial. With that 3" pulley connected to a hydraulic pump, of course connected to a compatible hydraulic motor. which spins the pmg the torque and force from the blade would be captured by the hydraulic circuit, considering hydraulic circuits have very little loses from input to output. could u gain rpms and inturn more energy? may also have to balance the mill with a flywheel some where in line before the tail just throwing this idea out there see if it sticks.
