In my previous two questions regarding temperature regulation and Rotations I set up the idea of creating a multi-layered shell world consisting of planetary crusts stuffed inside one another creating multiple planets in the space of one. In this continuing series, I'll be looking at sectioning the layers to be most efficient.
In a galaxy far far away, the Imperator of a Stellar Civilization decides to create a monument to his empire's technological achievements by creating a multi-layered shell world. He designates a convenient portion of empty space along a proper orbit around their star as the site for this world. They dedicate an astounding amount of resources and energy to complete this project. But as always, another issue occurs.
How would a shell world like this be best sectioned to utilize the energy from its core and the incoming solar energy?
What I'm looking for is how to be most efficient between layers baring in mind that some of these layers will be used for habitation while others will be used for industry and so on and so forth. For reference, habitable temperatures for this species are between -5 and 40 degrees Celsius and to stick with a nice solid number we can assume 7 layers will be created on this project.
