NanoraptorI think before we try a Dyson sphere around a star we should start with something small and simple like a magnetar. We can harness some of that magnetic rotor and the Dyson stator can just give us simple free energy
Tim ChaseLook who's being so fancy with a Dyson sphere. Maybe start more simple with a Bissel sphere or a Hoover sphere. Or perhaps an old-school Electrolux sphere.
