129,620 | In a galaxy far far away, during a fit of inspiration for a super massive marvel of technology, the Imperator dedicates an astounding 10% of energy and materials from his civilization's dyson sphere and solar materials processing units to attempt an innovative (and possibly insane) plan to create a matryoshka world.

] | You *do* want to freeze the outer shells and bake the inner shells. That is the entire point of a Matryoshka Brain. The entire point is to be able to create a multi-stage Carnot engine with a massive number of stages, and an incredibly high efficiency. This will implicitly call for hot inner shells and cold outer shell... | Your comments suggest your already aware of Septerra Core, so maybe use it's solutions.
The upper shells are a desert, the top being a polar desert, the second being a warmer windy desert, and the bottom being a warm dark jungle with plants competing for the little light available and the heat coming from the lava on ... |

The outside layer is going to have a temperature dominated by the cold of space, at something like -270C. It's really cold. Heat is going to constantly flow through it. You need to make sure that the energy from 1 star can pass through th... |

**Why does a civilization capable of producing a Dyson Sphere require this boondoggle?**
If it's a vanity project, because the Imperator wants to build one, sure, no problem. But the inner (or outer, depending on star type) ... |
