Entropy production gets a system update.

if you consider something as many interacting subsystems, you arrive at a "stronger version of the second law," which has a nonzero lower bound for entropy production that results from the way the subsystems are connected. In other words, systems made up of interacting subsystems have a higher floor for entropy production than a single, uniform system.
