@Milehigh Your test doesn't really change anything. Let's assume for the sake of argument a shorted generator coil can cause less rotor friction compared to a coil driving a load because it removes almost all of the tangential disturbance torque and radial disturbance forces on the bearings as the flywheel rotates. Assume these effects more than offset the energy burned off in the coil wire and the core material. So who is to say that a load cannot do the same thing? In other words, assume that a load with a low resistance that allows current to flow from the generated EMF but at the same time reduces the disturbance forces. If this is the case the flywheel might also take longer to spin down when driving a load. I guess I should clarify some things, first I have built countless motors and generators and if built properly with precision bearings and a balanced rotor then these disturbances you speak of are so small they are not worth considering, we should remember that a force is not energy nor a loss of energy. Now if we want to test this generator using scientific methods then I think we need to remove everything which does not matter so we may see clearly that which does. That is the only effects we need be concerned with are the electromagnetic drag forces relative to the electrical energy generated. This means the AC motor must be removed leaving only the rotor with magnets on it which can be considered as a flywheel, this flywheel has mass and a velocity thus a change in velocity represents a change in momentum(MV). 1) If we spin the rotor to 1000 rpm with no coil present then measure the time it takes to reach 800 rpm then we know the change in velocity (angular velocity) over time which is a change in momentum over time and these are losses which have nothing to do with the generation of electrical energy. These losses are relative only to the flywheel itself. 2) If we spin the rotor to 1000 rpm with the coil present but open circuit with no load then measure the time it takes to reach 800 rpm then we know the change in velocity (angular velocity) over time which is a change in momentum over time and these are losses which have nothing to do with the generation of electrical energy. These losses are relative only to the flywheel and the coil core. 3) If we spin the rotor to 1000 rpm with the coil present and attached to a load then measure the time it takes to reach 800 rpm then we know the change in velocity (angular velocity) over time which is a change in momentum over time. We can also measure the output electrical energy which the coil has generated as Voltage and Amperage over time powering a known load. Now if we know the change in momentum over time due to only the flywheel losses in (1) and we also know the flywheel and core losses in (2) and we know the change in momentum of the input from the flywheel relative to the coil output in (3) then it does not seem that difficult to do the math here. The losses in (1) and (2) have nothing to do with the generation of electrical energy while (3) does and if we deduct (2) from (3) then we will know the losses related directly to the generation of electrical energy relative to the electrical energy which was actually generated and measured as an output to a known load. I think that knowing where the losses occur and why is the first step in determining what is happening and while this is not an exact science but more of a comparison it is still better than what I saw in the video. We could also use a passive device such as a hall effect sensor to measure small changes in velocity as the magnet approaches and leaves the coil when using only the flywheel effect to determine if a so called accelerating effect is present and where it occurs. The hall effect sensor would also give us an indication of the frequency at which the magnets pass which relates directly to the velocity, change in velocity over time thus change in momentum over time. It can also give us an indication of the instantaneous position and velocity of the magnet relative to the induced voltage and current in the coil. As well if these facts are different than a generator powering the same load but driven by an AC motor then we could determine if the changes in accceleration inherent in the AC motor may be interacting with the changes present when the magnets passed the coil in which case the AC motor must be considered an integral part of the process. In any case the video in question really gives us nothing in the way of facts in order to understand what is actually happening. Regards AC
