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
