Permanent Movement is a movement of bodies that last forever in an undisturbed system. A standing motion machine is a virtual machine that can operate without an external power source. This type of machine is impossible, because it violates the first or second law of thermodynamics. These laws of thermodynamics apply regardless of the size of the system. For example, the movements and rotation swivels of celestial bodies may seem like planets permanent, but they are actually subject to many processes that slowly dissipate their kinetic energy, such as the solar wind, interstellar resistance, gravitational radiation, and thermal radiation, so they won't continue to move forever. Thus, machines that extract energy from limited sources do not operate indefinitely, because they are driven by energy stored at the source, which will eventually be exhausted. A common example is ocean current instruments, which eventually derive their energy from the sun, which will eventually burn. Machines have been proposed to operate at more obscure sources, but are subject to the same inevitable laws, and will eventually subside.
