The mass difference, of cylinder to sphere, is only about 3 to 1.There are not two spheres only one. Half the motion is on the other side of the center of mass still in the mass of the cylinder. The motion is complex.

All the motion comes from gravitational potential energy. The sphere’s tether gets very long, but the sphere is moving very fast.

If angular momentum is conserved the arc velocity of the sphere would become only .375 of the original speed of the rotating cylinder; because of the long radius. It is obvious that the sphere velocity is much higher. And the gravitationally source is not at the center of rotation: as is the situation in space.

For kinetic energy to be conserved the top velocity of the sphere would have an increase from only 1 to 1.73.

If momentum were to be conserved the velocity of the sphere would have an increase from 1 to 3. These higher speeds seem more apparent; especially since the sphere can stop and lift a falling cylinder.

One might ask why the sphere does not return the cylinder to the top starting position. Well the cylinder’s spinning first has to be stopped and that takes time. It takes time for the sphere to restart the spin of the cylinder in the opposite direction. And it would take time to bring the cylinder back up to another stopped position at the top. Going from stop to stop would take a ton of time. And in all of this time the cylinder is under gravitational acceleration.  It is amazing that the single sphere gets the cylinder as far back up as it does.

Sorry: that the release position is not in view; it starts just above the viewing area. There are two strings on the cylinder and the sphere is in the center.

I think these kinetic, gravitic, whatevertic ideas are a good thought experiment, but when you have your "analogy" figured out with the balls and strings then you want to convert that idea to something that is not diminished by air drag or friction. Humans think you want to go bigger and bigger, but the correct answer might be to go smaller and smaller. maybe even to molecular levels. If you got problems in transfering the energy back from molecular level then just heat water with it and use a turbine.

Even electricity has inertia so if your idea is kinetic, you might be able to do a solid state version of it.

The reason this works is because you can apply the same quantity of force for different periods of time. You can apply the force for a short period of time on the side going up; and on the side going down you can apply the same force for a long period of time. This process will produce massive quantities of energy.

By throwing a mass up fast; you can pass units of distance that result in only minimal loss of momentum.  By changing the arrangement of the applied force (from the same mass); these passed units of distance can give you larger units of momentum on the way back down.  Momentum is a function of time.

An example for a one kilogram mass: The first meter of an upward throw of 100 meters only costs you .222 units of momentum. The same meter of drop on the way back down can give you 4.429 units of momentum. The speed of the upward throw of 100 meters; changes from only (square root of (100 m*2*9.81m/sec/sec) 44.294 m/sec to 44.0724 m/sec in the first meter up. But you get 4.429 units of momentum on each individual meter on the way back down.  You gain (4.429 -.222) 4.207 units of momentum.

It takes .4515 sec to drop one meter: that means you have applied the force for .4515 second.

If you are moving up at 100 meter per second you can cross 19 meters in .4515 second.

On the way back down ‘each’ of these 19 units of distance can be crossed in .4515 seconds; this is 18 more units of time from the same distance of 19 meters. Gravity does not make you pay for these 18 extra units of ‘time’ over which the force is applied.

In the kilowatt hour you are paying for each unit of time ‘of the applied force’; you won’t get 18 free units.  Gravity will apply the force for free.
