Acceleration isn’t irrelevant. You don’t get to pick and choose which part of the operation of the generator you want to pay for. To run a generator you must pay for its operation from the moment you turn it on when it is at a dead stop. I said the heavier rotor draws more amps. It does. That is a fact. It costs more amps to get it up to speed. Now you can babble all day long and you can quote whoever you want, but you cannot change the facts. And I really can’t learn anything from someone who doesn’t know what he is talking about. And the constant amp draw of maintaining a heavier rotor at constant speed is greater than the constant amp draw of maintaining a lighter rotor at constant speed. The more load you put on a motor the more work needs to be done, the more you need to increase the Power to do that work. Since P=IxE (or power equals current times voltage) you need to increase something on the other side of the equation to make it true. If P goes up then either I (current) or E (Voltage) needs to increase as well. Usually you can't increase the voltage so the only thing that fluctuates will be the current. Motors are only rated for a certain horsepower, which really means a certain voltage/current combination. The hp of a motor is not a rating of how much mechanical power it can produce, it is a measure of how much heat it can shed. A 1 hp motor can turn a 3 hp load for a limited amount of time. A motor is very similar to a fuse. A 100 amp fuse will allow 100 amps through, but it will also allow 150 amps through for a certain amount of time before it will overheat and burn the element in half. A 100 hp motor will handle a 150 hp load for a certain amount of time before it overheats. For the LAST time, increased weight of the rotor is an increase in resistance to turning or increased LOAD on the motor. Come back when you have done your research and know what you’re talking about.

Hi Turion,
you still think you're smarter than Newton. Pity. You should respect our heros of science and learn from them.

It's been a month now since you were spending a day to test your device. Good luck on your next attempt.

BTW, I do realize the difference between weight and mass. However these quantities are pretty much universally considered equivalent on the surface of the Earth though a simple conversion factor of 2.2 pounds per kilogram.

Turion,
This issue about acceleration is irrelevant to operation of the generator in the expected application that is a constant source of power for a household or such. It is much like your magnetic neutralization and speed-up with load which are also irrelevant to operation. That's why I try not to argue about those because they don't matter. I was just trying to correct a false statement you made hoping you'd learn something from me, or Sir Newton.

So if you have to accelerate it, and that depends on mass, it DOES cost you more amps, just as I have said. So once again you are wrong.

Show me where I claimed it didn't take more to accelerate the heavier rotor? I never did.

And if you change to a bigger rotor, which is exactly what I was talking about, and you have to accelerate it, it costs you more amps than the smaller rotor. THAT was what I was talking about.

But that is not what you said.

The REAL question here is that when two rotors of different size and therefore different weight have accelerated to speed, are turned by identical motors, and are not acted upon by outside forces, is there a greater cost to maintain the rotation of the larger rotor. I maintain that there is. You claim there is not. You quote Newton to back your claim. There is a greater RESISTANCE from the larger rotor so it WILL draw more amps. Just as I said. You are just a waste of my time.

You said heavier, not larger.
