If I remember my stuff from a Chemistry degree 40 years ago then Entropy is
unrelated to the laws of Thermodynamics. ISTR that Entropy always increased. [ Reply to This | Parent | # ]

As I recall the argument - (from about 1972) it goes like this:
1. a diode only permits a current to flow in one direction
2. to implement a diode requires an energy gap such that the amount of energy
required to flow in one direction is less than the energy required to flow in
the other.
3. Given a small enough energy gap, then thermal excitation should cause
electrons to cross the gap, but not be able to return.
This turns the diode into a battery, with the result that the temperature of the
diode decreases.
This is effectively an implementation of Maxwells' daemon:
