I can imagine this situation:
A spaceship hangs dead in space, broken engine. New wheel shapped part needed in the engine. Astronaut goes for a walk on the outer hull. Magnetic boots malfunction and for a short instance repell. there the astronaut goes at speed V, and the spaceship the other way at speed V/1000.
The astonaut ties the wheel on his bag, and makes swimming motions, to no avail.
Then he takes the wheel, and spins it up. It having aerospace sped bearings, it can absorb vast amounts of energy. Astronaut needs to use alternating hands to prevent his own spinning, to not lose track of the spaceship drifting away from him (her). At exactly the right angle, the astronaut take an intentional blow to the helmet from the wheel, and starts catching up witht he spaceship. Yet, can (s)he grab the wheel and take it along, or will that even out to drifting away from the ship again? This is where a good biosteel wire would have come in handy.

Before I came to this conclusion about spin in general (after watching Walter Lewin's lecture), I have realized that the precession and resistance that a spinning wheel or gyroscope poses could be used to create a total acceleration. Its not that hard to see, but it may be hard control where you are going

But you could also use it the other way around. Instead, you attach both ends or handles of a bicycle wheel (space wheel  ) with an attachment mechanism to the center of your own body. If you then begin to pull or push on the wheel to spin it, it will push on the middle of your mass, and thus only accelerate you forward/backward without creating a disorienting total spin.

You would then only need to push for an interval on the wheel, and then slow it down again on the opposite side (if it laid horizontally in relation to you) to create a propulsion in one direction.
Can you imagine this?

you can replace the magic hand with a servo motor at the pendulums pivot point.

all the magic hand is doing is replacing the stored energy that was lost on its return back to the magic hand. kinetic forces only store energy, once that energy is used up it will come to a stop.

all lost newtons will have to be replaced in order to keep the model going. there is no OU here, it is only stored kinetic energy.

You are talking about the Milkovic pendulum right?

Well, I don't think that anyone at this point is denying that the pendulum will come to a stop once its kinetic energy is used up due to losses. However I do think that many would object if I said that the energy required to keep it running is the same or more than what it can output. But I wouldn't really call it overunity, just energy free for the taking.

Hi folks,

please go back to page 100, Reply #991 on and review I_RON measurements
