Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Perpetual motion machines are fundamentally precluded by the laws of thermodynamics, particularly the second law.

The analysis

The claim that perpetual motion machines violate the laws of thermodynamics is strongly supported by multiple papers in thermodynamics (e.g., [4], [8], [9]) which explicitly state that the laws of thermodynamics preclude perpetual motion. There are no refuting papers.
