The structures of the power plant basically revolve around the central SMBH in Keplerian motion to form “Dyson Shells.” In an advanced case of Type II, the central star is almost fully covered to form “Dyson Sphere”. Here we discuss the case of structures partly covered, or the Dyson Shell type, and call it a Dyson Sphere. Unlike a stellar environment, or Type II Dyson Sphere, there are complex structures like relativistic jets, accretion disk and accreting matters, rapidly rotating stars, etc., and hence it would be very difficult to construct a fully covered structure, like a system studied by Birch over a large gaseous planet (e.g., Jupiter). However, it is not easy to set numbers of power plants with similar distance orbiting around the central SMBH. Hence, it would be a possible solution to set the power plants on a solid framework, something like structures studied by Birch. Some areas should be kept uncovered to yield emanating jets and accreting flows.
