Re residual tidal energy dissipation: That's a damn good question, and I wondered about that myself. This is very much unexplored territory, though. I don't think that we have a very good understanding yet of the thermodynamic behavior of "cryo-icy" bodies like Pluto. Bluntly speaking, this world is extremely freaking cold, and the critical points for a wide variety of materials are rather closely clustered around the expected variations in ambient temperature.
We may find that dynamism in terms of geological activity is in fact a very relative function in the context of a given world's environment. It may take far less energy to induce global changes on a body of any random composition with numerous caveats re tidal situation & solar heating levels then we've assumed. If true, this is unexpected & quite interesting. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
