No one, and no one ever will, since perpetual motion machines are a scientific impossibility.
Because perpetual motion can not happen
Perpetual Motion Machine
No, perpetual motion is prohibited by the laws of thermodynamics.There are machines that might at first seem to be perpetual motion machines but only because their source of energy may not be readily apparent.add. But in economics, inflation serves the purpose of a perpetual motion machine, in which more currency is created continuously. And which serves to illustrate the reality of economics.
Such a fictional machine would be called a "Perpetual Motion Machine".
Perpetual motion machines do not exist. If they did we would not be paying almost $3.00/gallon for gasoline, as a perpetual motion machine implies free energy. Newton's laws tell us that is not possible. For further explanation read up on Newton's laws of motion and thermodynamics
Perpetual motion machines are theoretical only. No one has actually invented one. A perpetual motion machine would have to be able to provide its own source of energy to continue operating.

Perpetual Motion Machine.
Its a machine that has to be started but doesn't need to be restarted.
There is no answer to your question because a perpetual motion machine is impossible. If one could be built, its own motion would be considered work.
A perpetual motion machine of the first kind it what we usually mean by a perpetual motion machine. A device which once started will continue to run and do useful work forever without the need to add energy to keep it going. The laws of physics make such a device impossible.
it depends on what you use to build it
