Exactly Erich! This is a simple principle and I suppose a simple explanation has taken a long time to surface, but we are getting there. Input motor turns a shaft at 60RPM with or without gearbox. Swinging pendulums fitted with clutch bearings lever the same shaft. What have we got? Reduced input current. What does that do? Increase motors efficiency. Correct? Now there is the part where the next gearbox changes the 60RPM to 3000RPM. This is where the alternator attaches. Here is the simplest bit. Does increasing the leverage by adding more weight, longer arms or increasing the diameter decrease the input motor current? Does it also increase the torque available after the final drive gearbox? Again I already know the answer. I'm testing you guys. It seems the whole mechanical design gang have been brainwashed with maths and theory instead of doing real experiments. I'm waiting to see who is the first one to click and then amaze me as I get left in the dust.
