Massless Drive - Sussed it.

Well, obviously not, there's clearly something wrong with it, my understanding of physics is pretty poor.





Spin a disk until it's at relativistic speeds and it gains mass? (I think)



Shoot it from one end of a tube to the other and it provides thrust?



Stop it spinning, then stop it moving and then send it back.



Now, there's x kg moved from one end of the tube to the other and x + y kg back the other way but everything's back where it started.



Have I generated any thrust at all?
