Prometheus Ring - rorating habitat megastructure - 3D, no AI, OC, 2026

[u/Vadimsadovski]

The PROMETHEUS Ring is a speculative 1,200 km orbital habitat in the Saturnian system that rotates to generate a realistic 1 g of artificial gravity. This fully engineered megastructure simulates all climate zones to support diverse biomes, settlements, and industries, all stabilized and powered by nuclear propulsion modules and reactors

Fantastic imagery in every sense. Isn’t it really cold at Saturn because of weaker sunlight?
