Black Hole Dyson Spheres: Energy Harvesting Potential and Detection Signatures
To the point
Freeman Dyson's idea of surrounding a star with a megastructure to harvest its energy inspires the proposal that a similar Dyson sphere around a black hole could collect energy from the accretion disk and related processes, delivering far more power than a star and potentially detectable from afar through ultraviolet and infrared signals and subtle gravitational effects.
