earth's interior heat is the engine that powers what processes?
geological
external sources of planetary heat (namely, radiation from a planet's host star) can have drastic effects on geodynamic regime. with all other variables held constant, an earth-sized exoplanet with a surface temperature of 273 k will evolve over its geological lifetime from a plate tectonic regime, to episodic periods of plate tectonics interspersed with stagnant lid geodynamics, to a terminal stagnant lid phase as interior heat is exhausted. meanwhile, a “hot” planet (759 k surface temperature) under the same initial conditions will have an amorphous surface (due to lithospheric yield stress being constantly exceeded) to a stagnant lid as interior heat is exhausted, with no plate tectonics observed.

the benefits of turbine engines as explained by chrysler engineers were reduced maintenance, longer engine life expectancy, large development potential, overall parts reduction of approximately 80% (60 parts rather than 300), requirements for tune ups nearly eliminated, low temperature starting difficulties eliminated and no warm up needed, antifreeze is not required, interior heat is available instantly in winter, no engine stalling with sudden overload, engine operates without vibration, oil consumption is negligible, reduced engine weight, exhaust gases are cool and less pollutant, and most importantly, a wide range of combustible fuels may be employed as a replacement for petroleum gasoline.
