Pre-Biotic Earth and a More Complete Theory of Heat Transformation, Part I

The emergence of biological complexity from abiotic chemistry remains thermodynamically unexplained. Existing frameworks, such as Prigogine's minimum entropy production theorem, the maximum power principle (Lotka and Odum), and exergy (Rant) each capture one aspect of a dissipative structure, but none has quantified all its thermodynamic properties as a coherent set derived from a single physical model. This paper introduces the gravitational dissipative structure (GDS) and provides that complete quantitative framework. Grounded in Clausius's interior/exterior work distinction and his force-balance reversibility criterion, the GDS model derives six thermodynamic properties, including complexity yield, specific heat quality, and heat transformation effectivity, and proves two theorems: first, that dissipative structures are more effective at transforming heat into stored energy at greater local heat sink temperatures; second, that the ratio of real efficiency to Carnot efficiency is constant regardless of boundary temperatures. Applied to Earth's tropospheric water and air cycles, the model yields auto-powering capacities of 82 W/m² and 345 W/m², with 98.8% of initial heat quality retained. Their combined heat quality outputs estimate the actual measure of jet stream velocity to within the same order of magnitude, cross-validating the GDS model and the concept of heat quality networking. When GDSs network at planetary scale, the result is massive mixing, a geological-timescale concentration of dissolved salts, acids, bases, and minerals that provides the multiplicity of microstates and ergodicity of mixing required for spontaneous prebiotic chemistry. This is Part I of a four-part series; Parts II through IV build on these preconditions to demonstrate the inevitability of life. Earth is a naturally-organizing machine, driven by heat and conservative forces to generate life.
