Penrose Sphere

A large mirror built around a Black Hole. Radiations are bouncing back and forth between the mirror's inner surface and the Black Hole's ergosphere, generating energy.

Stages
Penrose Sphere Construction Site

This platform houses the personnel and infrastructure necessary to construct a Penrose Sphere around a Black Hole.

Penrose Sphere Frame

This skeletal frame will one day hold massive mirrors, built with the most reflective materials we can possibly think of. Once we finish constructing those mirrors, we'll have the choice to either turn the structure into a massive bomb, or use it to harvest energy.

 Bomb Path 

Unarmed Subspace Distortion Bomb

This Penrose Sphere has been re-purposed into a bomb. We must now let it accumulate energy for a while before detonating it.

Subspace Distortion Bomb

A large mirror-like structure built around a Black Hole, capable of reflecting radiation back and forth between its inner surface and the Black Hole's ergosphere, causing superradiant scattering and exponentially amplifying the radiation's energy.

 Energy Path 

Penrose Sphere

A large mirror built around a Black Hole. Radiations are bouncing back and forth between the mirror's inner surface and the Black Hole's ergosphere, generating energy.

Stabilized Penrose Sphere

A fully operational Matrioshka Brain, including the outermost layer consisting of the cross-referencial archives which coordinates the other components, boosting efficiency to its maximum. Grants a +25% boost to research speed, unity, robot output, as well as naval cap.

 Ringworld Path 

Ringworld Penrose Sphere

Parts of this Penrose Sphere's output have been redirected towards supporting a massive and highly advanced ringworld built around it.

Penrose Ringworld Segment

A massive chunk of a ringworld, consisting of two habitable segments and one support segment, powered by a Penrose Sphere.
