::: Probably the place where the Second Law comes into play is that it says that even if you have a perfectly idealized "closed system," within that system ''energy'' won't be lost, but nevertheless energy ''observable as macroscopic motion'' can still degrade into heat energy ''no longer observable as macroscopic motion.''

== The Uncertainty principle doesn't invalidate Perpetual motion... ==
The Heisenburg Uncertainty Principle applies to sub-atomic particles like electrons only, we cannot know where they are at any given time because of Brownian motion. It does not apply to anything that can be seen without the aid of an electron microscope. Also, entropy doesn't increase, and the Second Law of Thermodynamics merely states that the universe tends towards Entropy. Also, the lack of creation of energy would be the Law of Conservation of Energy, which is present in many parts of Physics beyond the First Law of Thermodynamics. Also, the Earth is not a perpetual motion machine, to argue that it is does not border, plunges headfirst into absurdity and ignorance. Finally, the Earth has been slowing at a rate of about 2.2 seconds every 100,000 years due to frictions, no one considers it a perpetual motion machine.
