RE: Perpetual motion
what freethinker describes is known as the 2nd law of thermodynamics. The idea that this disregards a perpetuum mobile is as follows:
spontaneous processes only occyr if the enthropy increases. Thus causes the system to lose energy E.
Now to put the system back in it's original state the same energy E has to put into the system.
So in principle if we do the energy conversion 2 times (in and out of the system) with perfectly no energy loss a perpetuum mobile can be build.
But The 2nd law also implicates (after some mathematical manipulatyions):
- The energy transfer of one system to another can never be 100% efficient.
