If you are switching a super conductor on and off while moving in a circular motion (in a vacuum) can that produce a net force in a direction?
(This is how a UFO could work?)
When you attach a superconductor to a rotating disc you can make it so it only loses energy when the superconductor is switched on and flux pinning occurs if the magnet is
sufficiently close it’s obvious what happens as the magnet is pinned and will begin to move locked with the superconductor.
Your spaceship will gain momentum while the earths magnetic core will lose some momentum (or the suns magnetic core will lose some momentum). If you can produce 9.8 newtons of force you can counteract the forces of gravity. The issue with flux pinning is that it requires the superconductor to be near a strong magnetic field to work noticeably (This is why I suggest spinning it to multiply the effect the momentum transferred if there is any sort of partial pinning in weaker fields, this is the big question).
Video of ‘quantum locking/flux pinning’ happening in the opposite manner of what I’m suggesting.
So (My) the idea is, instead of a magnetic track, You have super conductor(s) turning on a circular disc and the magnet (earths magnetic field) is stationary.
The super conductor would turn on when facing the field… and turn off at the point you want to “release” the magnetic field.
As you can see from this article it’s possible to turn the magnetic field on and off fast enough to handle any frequency of spinning disk.
Again, does that mean super conductor needs to be close enough to the (earth/suns) magnetic field before it can do any sort of transfer of momentum/locking?
If that’s the case then this sort of engine will not work..
I posted this question on reddit:
The only response I got worth reading was from John Hasler was simply:
There’s some interesting ideas there as well. It’s a different type of space engine? or maybe not that much different:
If you take a look into special relativity.
However it is one that has been investigated and will probably work, unlike my untested idea.
I was hoping for some crack physicist to solve the physics questions for me.
1. How much momentum is transferred based on distance from the magnet or how much it is pinned.
2. Is there a partial pinning? No? I just wasted our time sorry.
3. Can you improve pinning by creating angular flux tubes or more tubes?
