Part of the vagueness in the brief post about how the ether model deals with thermodynamics is due to the fact that there's a lack of interest and research into the question of whether an ether could exist. There are mountains of research into quantum physics and no interest in looking into the ether.
Trying to extend that brief description of thermodynamics and ether into questions like how could that kind of model deal with a question, for example, of how solar energies arise, versus the energies involved in internal planetary heat, would have to contend, rivalry-wise, with mountains of research and theories/hypotheses that have been done, entirely based on the quantum model.
So while it would be interesting to discuss how the ether model could be extended to questions like cosmic forces and cosmic bodies, at present my basic ether model has gotten so little recognition, it seems a pointless effort.
