If someone were to send a probe out to interstellar space, bring it to a full stop and start rotating, would it continue rotating eternally? Or would drag from errant plasma slow it?

But it would be a way to store energy, though.jtbell said:There's no way to extract energy from this particular device without slowing it down.

A perpetual motion machine is a hypothetical device that can continue to operate without any external energy source. It would essentially generate more energy than it consumes, which goes against the laws of thermodynamics.
No, it is not possible to create a perpetual motion machine. The laws of thermodynamics, specifically the first and second laws, state that energy cannot be created or destroyed and that there will always be some energy lost in the form of heat. Therefore, a machine that continuously produces energy without any external input is impossible.
Despite the scientific evidence against it, people still try to invent a perpetual motion machine because it has been a dream of many inventors and scientists for centuries. It is a challenging and intriguing concept that has captured the imagination of many, but unfortunately, it is not feasible.
No, no one has ever successfully created a perpetual motion machine. Many have attempted to do so throughout history, but all have failed. Some have claimed to have created a perpetual motion machine, but upon further investigation, it was found to be a hoax or a misunderstanding of the principles of physics.
As perpetual motion machines are not possible, they cannot be used for practical purposes. However, the concept of a perpetual motion machine has led to advancements in energy technology and the development of more efficient machines. So, while a perpetual motion machine may not exist, the pursuit of it has contributed to scientific progress.
