    Ah, no - that's not the way it works. YOU claim it adds gravity so YOU have to show proof that it does. (Not that you will ever be able to.)

    A whirl-pool will suck you in
    A Tornado will suck you in

    Why doesn't a spinning object suck in the atoms around it?

    And neither of those have ANYTHING to do with gravity at all. The forces there are called partial-pressure. A fairly weak vacuum - suction, if you wish.

    A spinning object will actually throw things AWAY from it. Never ridden on a carousel?

    Your looking at the inside. The outside is doing the exact opposite.

    You forget there's an eye to a tornado and a circle in a whirlpool.

    No, a tornado doesn't have an 'eye' as such - that's a hurricane. And a tornado pulls things in at the bottom and slings them our at the sides. A hurricane destroys with the tremendous winds spinning around it's wall and the effect - since the storm is so big - is just like a straight wind blowing things away. And NEITHER of them have anything at all to do with gravity.

    You'd probably have better luck using the air compressor AS the propulsion device.

    Oh Jesus.

    An Ion drive is exactly what you thought up. Even though space may contain a few particles, capturing the energy from them would be a better job for a solar sail. If you used solar panels to collect the energy from light, or nuclear power, you could accelerate a stream of ions (charged particles), out the back of the ship at very high speeds (small masses at high speed=large masses at smaller speed). You could even carry all the ions you need with you, instead of collecting it from space.

    You will note the fact that Read-Only was extremly correct in saying the tornado does not have an eye as a hurricane does. Yes it is a form of funnel, but following your logic, my air duct has the eye of a hurricane.

    Next your link simply described the Centripetal force: an artificial gravity of sorts, however not the force of gravity. It also has no bearing on objects not within the rotating station.

    The only 'gravity' a rotating object can contribute (versus one of the same mass thats non-rotating) is that of it's kinetic energy (thanks to E=mc^2) however, this energy will have to come from somewhere, and your better off just leaving it stored there than trying to spin something with it (it will still weigh the same whther it be stored in a battery or rotating the ship.)

    You asked for proof that spinning objects dont produce gravity? Well I want proof that dragons, unicorns and Peter Pan do not exist. Cant give it to me? Then they must exist no? Dont worry though, both are arguments ad ignorantiam, and therefore invalid. If you can supply proof that rotating objects produce gravity, then we are getting somewhere.
    The examples you have thusfar given, whirpool and tornados/hurricanes are all examples of a vortex (more or less) You can read about the physics of them if want an understanding of whats going on, but they do not increase the force of gravity.
