Dyson Sphere
A Dyson Sphere is a megastructure built around a star to harness all of its energy. Many large factions have Dyson spheres, such as the Hyperion Federation, HEX Mainframe, Cypher Dominion and more. Different factions build Dyson spheres in different ways.
Generally, most factions exploit the difference in radiation pressure from the star. As photons have momentum, photon intensity is proportional to force away from the star. Due to the inverse square law, the pressure of the side that comes closer to the star increases, while at the same time the pressure on the other side decreases. This results in a force pushing the sphere back into its desired position. Hyperion Federation:
Using a technology similar to Subspatial Starships, they place several support beams in subspace to prevent gravity from destroying the sphere under weight. Excess heat is conducted using temperature superconductors inbuilt in the sphere. Heat is radiated to several massive megastructure scale QEN heat vents to be radiated. Most HF Dyson spheres are habitable on the surface. Although the surface normally would not be touched by stellar radiation, holes are carved in the sphere. Large mirrors on towers redirect the radiation onto the sphere, lighting and heating it up. The towers rotate to simulate a day / night cycle. HEX Mainframe:
The HM simply just created a gravitational field in the opposite direction from the natural gravitational field. Anything on a HM Dyson sphere will be weightless. Excess heat is conducted using temperature superconductors and sent to small objects to heat up to immense temperatures. These are expelled from the sphere at millions of degrees celcius as a gas / plasma. As there is no gravitational field, the gas will not return to the sphere. Cypher Dominion:
The CD relies far more on star lifting than on Dyson spheres. They have not managed to make a full sphere due to a lack of method to cope with the immense gravitational force. Instead, the partial sphere spins. They use large panel radiators to manage heat. Their star lifiters use a large ring world close to the star. Inside the ring world is a large ring of magnets. These continually pulse a magnetic field at a very specific frequency. This causes resonance, and the star to expand in 1 direction. The plasma that is expelled is collected. Sulethis Republic:
The people of the Republic are terrified of space. Their Dyson 'spheres' are entirely managed by drones. Their 'spheres' have many docking prts for drones to recharge on. There are also automated factories designed to mass produce drones at a large rate. However, they deal with the issues of gravity by.. not being a sphere. A SR Dyson 'Sphere' is actually a large collection of ring worlds indifferent orbits. They are less efficient than an actual sphere because much of the radiation still escapes. This form of sphere is much more reliable however.
Star Lifters are a similar, though different concept from Dyson spheres. A star lifter extracts stellar plasma from the star often in large quantities. Surprisngly, this can often be good for the star, increasing its lifetime.
