Thermodynamic equations for a black planet with nearest-neighbour surface Carnot interaction.
Abstract
Consideration is given to the thermodynamics of the relationship between the external and internal interactions of a black planet with an external source of energy. Thermodynamic equations are derived for the case of a spherical planet with a skin made of a black, rigid, perfect heat conductor covered by a net of boundary lines representing a certain geometry, which is in a circular orbit around a star emitting a black-body spectrum. The approach thus provides a quantitative description of the work efficiency of a compound system with a natural separation between the entropy-producing channels and the zero-entropy channel, and results in a generalization of the concept of Carnot efficiency.
