The gyroscope never lost energy from the perspective of a local observer who is also unaware of any time dilation without use of external measurements... The frame only appears contracted and slower from our frame of observation because it is displaced into the 4th dimension.

Any energy loss would show up as an increase of energy of the system that applies the retarding force. In order to get your gyroscope into a higher position than it begins requires you to apply a force against the gravitational field. The device that applies this force must do work upon your scope. The amount of work required for each direction of travel is equal provided the final location and velocity of the gyroscope equals the starting condition. No net energy would be consumed.

I am devising various mind experiments to help me understand it. So I thought I would pose my first mind experiment to see if anyone has some insights that might help me. This is my limited understanding of this part of the theory that applies to this experiment. For an external observer, time slows down for an object that approaches a large mass. I also understand that experiments have validated this theory using atomic clocks. If the mass is large enough, such as a black hole, time will theoretically stop, or nearly stop. My mind experiment has to do with a larger macro type object, rather than the vibrations of the atoms in an atomic clock. For this mind experiment I am using a high speed, low friction gyroscope. If I understand the relationship between mass and time for an external observer, the gyroscope should slow down as it approaches a large mass and the rotations would return to normal speed when pulled away from the mass. If this is the case, where does the energy go when slowing down the gyroscope by approaching a mass, and where does the energy come from to return the rotations to original speed when pulled away?
