I think it is possible.

magnetic field - like in spell binders??
gravity - anti gravity - like in many sci-fi including ultravialot??

If we change the graviton to some other energy form, then there you have it.

| I believe you could use a magnetic field to levitate, not sure about using it to fly, since I can't see how that would create life except via a magnetic interaction, which would be levitation. |

Well, the Earth has a weak magnetic field of its own. I don't know how strong an opposed magnetic field you'd need in order to lift something, but technically it stands to reason that it would be possible.
Maybe the Earth's field is so weak that no amount of magnetism pushing against it would lift you. |

The above pic is a design of a new propulsion system.
It is very simple. Some of you guys may have the access to build and test it.
The principle is space is a magnetic field. If we rotate a fan that is made by superconducting material in a vacuum chamber and keep it below critical temperature, we should have a thrust of magnetic wind.
Maybe that's how UFO's fly around. Because magnetic wind moves no mass, the new motor should be high efficiency. |

Magnetic fields? Possibly, though you would need a very very powerful supercooled superconductor, and it would only work on the planet. And, as has been said, the planet's magnetic field might be too weak for it to work.
'Gravity?' It depends on how you want to use it. If you want to make some sort of anti-gravity wave or material then I will have to say No -- I have gone into great lengths on the "gravity-we know what it is-but do we know why it is?" post in the astronomy section already on this one, which I won't delve into here so as not to hijack your post. If you want you can check it out to see why I say no to using 'gravity' ... but, one could possibly devise some way to curve space artificially in ways that would benefit a spaceship.
However, we already utilize the effect of 'gravity' caused by curved space for our space missions such as sling-shotting, but we are simply utilizing the naturally-occurring curved space AKA 'gravity' that is caused by objects in our own solar system.

Well... if you apply Einsteins E=mc2, is is possible to create mass from energy, so theoretically, if you create an enormous amount of mass in front of your vessel, gravity will work, right?
If there in any way was possible to create this big amount of mass in the direction you want to go in a split of a second, it would work right?
My mind is just drifting here, but it sounds logically correct  |

Magnetic wind from a cooling fan?   you crack me up...how is this magnetic field created being anything to do with the wind?
