Is this merely an academic concept, useful for classroom teaching, or will it (can it?) have a useful application in the real world?
If so, what is its most promising or feasible use?

admin, you have my sympathy! (I should post this in Parenting as well, LOL! : )

It is theoretically possible to make perpetual motion machine. Link two masses with a string, go into space and enclose them in an evacuated sphere and set them spinning in the middle. They will continue to spin forever.
However, you will not be able to take any energy from the machine or else they will stop rotating. In effect, you will have a perpetual motion machine that would go for ever but wouldn't really do anything.

Impossible?? No, but hidden. Think about this, if a "perpetual motion machine" was revealed then so would be the secret for free energy. If there is free energy available then what happens to the electric corp giants? The people who have achieved this or have come close to achieving this have been silenced in one way or another. Think about a world of free energy, then remember how much we need energy and how that is the govt main source of control. If they lost that control where would we be as a society. We will find out soon enough, trust!

It is impossible to make a such a machine. It would violate conservation of energy, one of the most fundamental laws of nature.

Not to be cute but my kids are in a state of perpetual motion. LOL!

If it was achieved, imagine the choas it would cause. Think of the millions of people worldwide who are employed by the various energy industries. Their jobs would be obselete, the global economy would crumble. In short, I think it is achievable, but the technology is being hidden.

This apparatus is impossible according to our current knowledge of physics.

Been done. The government/ oil companies don't want you to know
though. Usefull purpose? Oh yeah. Think;.... travel.
