I believe the reference is to a computer simulation by
Skoros and someone else (The reference is on a broken
computer) where the trapdoors never stop moving. I think
the trapdoors should be allowed to slow down by friction
and not have their own motion since even nano scale pin
and bushing hinges are rigid.
Excerpted from the book: "The 2nd law of thermodynamics
has the same degree of truth as the statement that if you
throw a thimbleful of water into the sea, you cannot get
the same thimbleful of water out again" - J C Maxwell
A thimbleful of similar thermal content is easily
recovered from the sea so the burden of getting the same
molecules back is excessive and unnecessary.
