1. There are many kinds of type 2 perpetual motion machines. Behind each type is a natural phenomenon.

Machine A: against the irreversibility of thermodynamics (diffusion, heat conduction, friction, etc) - dynamics;

Machine B: Utilizing the Difference of Carnot Efficiency (Reversible Thermodynamics) - Thermodynamics

2. A and B belong to different disciplines. There is a parallel relationship between them, and there is no logical mutual inevitability.

Logic of Law 2 of Thermodynamics: Experience induction, denying that A machine==》 B machine can not be manufactured==》 All material Kano efficiency: 1-T1/T2.

3. The logic of the second law of thermodynamics violates the physical logic that A and B cannot deduce from each other.

4. The second law of thermodynamics elevates the "irreversibility", which is only a dynamic experience.

5. See the picture below for details.
