Perpetual motion machine

From Conservapedia

Robert Boyle's self-flowing flask appears to fill itself through siphon action. This is not possible in reality because a siphon requires its "output" to be lower than the "input".

A perpetual motion machine is a hypothetical isolated system capable of having internal motion indefinitely. Many attempts to build such a system have failed.

One type of a perpetual motion machine would continue to perform work without new energy, thereby serving as an unlimited energy source. This is prohibited by the First Law of Thermodynamics.

Another type of perpetual motion machine simply uses its initial energy to remain in motion perpetually. If entropy is always increasing, even in closed (and isolated) systems, then indefinite motion is impossible because an increase in the disorder of the system will inevitably disrupt the motion. The Second Law of Thermodynamics predicts that a perpetual motion machine in this sense is impossible, and none has ever been created.
