So if for my part I willingly agree to the 2nd principle in thermodynamics, I remain a little circumspect in other aspects of nature which do not systematically converge towards disorder.
However, I do not dream of making a monothermal engine. What the 2nd principle says, physically, is that only imbalances physicocical quantities can generate usable ordered work.
In addition: by only looking at the temperature, which by definition is related to the standard deviation of a particle speed distribution, inevitably, by averaging everything, we become myopic.
We no longer see the thermal agitation in its detail.
This thermal agitation is random, but the randomness occasionally creates conditions which seem locally organized.
the monatomic veil of graphene vibrates to the rhythm of these random "organizations".
This vibration is almost regular and the graphene veil coupled with thermal agitation can be likened to an engine.
