Abstract
Let’s begin with some examples of negentropy. Consider a box of gas composed of n classical particles. The microstate of the box is defined by n points in the phase space of a single particle. The macrostate can be described thermodynamically in terms of a much smaller number of thermodynamic variables including entropy. If the entropy is maximal (subject to some constraint) then the gas is in equilibrium and the negentropy is zero. No work can be extracted.
