Hawking Reactor

The Hawking Reactor takes its power straight from the evaporation of a tiny singularity: the lighter it is, the faster it evaporates and the more power it gives. To keep it alive, exactly the evaporated mass must be fed back as matter. That balance is unstable, so the reactor always needs Gravimetry, which runs the control. It starts from a Singularity Capsule split off a Micro Black Hole Plant.

How it works

  1. Put a Singularity Capsule into the item input: the reactor starts and charges its start energy.
  2. The singularity evaporates; the Radiation Collectors turn 0.9 of its mass energy into electricity.
  3. The control feeds Compressed Matter through the Matter Injectors: the evaporation plus a correction towards the mass that gives your power setpoint.
  4. Stop feeds the singularity up to a safe mass and dissolves it through the collectors.

Rules

  • Shape: a cube with odd edge length, at least 7, at most perf.maxStructureSize (default 16, allowed 5–32).
  • Edges and corners: only Singularity Frame.
  • Faces: Singularity Casing, Shielded Sight Glass, Inspection Hatches, Matter Injectors, Gravimetry, the ports and the controller.
  • Inside: the centre and the blocks one step from it stay air (the vacuum). Every other interior block is a Radiation Collector or a Coolant Channel; no air.
  • Needed: at least one Radiation Collector, one Matter Injector and one Gravimetry.
  • Ports (each works only on its outer face):
  • Energy Input Hatch: start and containment energy in.
  • Energy Output Port: the reactor's energy out.
  • Item Input Port: Compressed Matter and Singularity Capsules in.
  • Fluid Input Port: water in; Fluid Output Port: Hot Coolant out.

Operation in depth

  • Start: a capsule brings 3 ME. The reactor then draws 100,000,000 E from its input buffer (1,000,000,000 E) and runs.
  • Evaporation per tick = 0.4 ÷ mass².
  • Power = evaporation × volt.energyPerMassUnit (default 10000000, allowed 1000–1000000000000) × 0.9, up to half less with hot collectors, times volt.generatorOutputMultiplier (default 1.0, allowed 0.01–100.0). It goes into the output buffer (200,000,000 E).
  • Containment: 50,000 E every tick, from the input buffer first, the rest from the output buffer.
  • Feed: every Matter Injector feeds up to 0.05 ME per tick. The plant stores up to 1,000 ME of matter; each Compressed Matter is one ME. volt.fuelConsumptionMultiplier (default 1.0, allowed 0.01–100.0) changes how much matter the same feed takes.
  • Setpoint: the power you want, at most the safe power. The control aims for the mass that gives it (at least 2 × 0.3 ME). The buttons change it by 250,000 E per tick.
  • Safe power (shown in the window): what the injectors can hold, injectors × 0.05 × energy per mass unit × 0.9, with 10 % kept as reserve.
  • Collector heat: 0.05 of the collected energy heats the collectors. Coolant Channels carry it away as Hot Coolant (10 HU per mB), each up to 400 mB of water per tick. Every channel stands for 40,000 HU of heat limit; at the limit the reactor shuts down by itself ("collectors overheated").
  • Stability shows how much feed reserve is left beyond the evaporation; it halves without containment energy or without stored matter and falls with hot collectors.

Note

The setpoint stops at the safe power A setpoint above the safe power would let the singularity shrink to a mass whose evaporation the injectors cannot replace, so the setpoint never goes above it: neither the buttons nor the default (1,000,000 E per tick) can raise it further, and after a rebuild with fewer injectors it drops with the safe power. For more power build more injectors. The single injector of the example holds about 405,000 E per tick.

Warning

One slot for matter and capsules Matter and capsules share the one input slot. A second capsule waiting there while the reactor runs blocks the matter: the singularity starves and evaporates. Only insert a capsule into an empty reactor.

Shutdown and failure

  • Stop (or overheated collectors) feeds the singularity up towards 1.5 ME; once it is that heavy, it dissolves through the collectors and the reactor is empty again. This needs matter in the store.
  • Failure: below 0.3 ME the singularity evaporates completely ("ran away and evaporated", or "no matter" when the store was empty). Missing containment energy and a broken structure end the same way (both show as "structure broken"). Each failure is a radiation flash that hurts living beings nearby and leaves radiation behind for a while; see Incidents and Radiation.
  • After a failure the collectors are hot; Reset works once they have cooled down.

The screen

  • Lines: Status (structure) and Phase (with the reason).
  • Bars: input and output buffer.
  • Values: mass, stability, output, setpoint, safe power, matter feed, evaporation, matter, collector heat, start charge.
  • Buttons: Stop, Reset, -/+ for the setpoint.
Phase Meaning
Empty (needs a singularity capsule) Insert a capsule to start.
Starting The start energy is drawn.
Running The singularity evaporates and gives power.
Shutting down The singularity is fed up to the safe mass and dissolved.
Failure: ran away and evaporated / no matter / collectors overheated / structure broken Let the collectors cool, then Reset.

Automation

  • Pipe Compressed Matter into the Item Input Port. Insert capsules only by hand, or make sure a pipe only sends one when the reactor is empty.
  • Water in, Hot Coolant out to a Heat Exchanger.
  • A Sensor Module reads mass, stability, power output, energy stored, matter, phase and reason.

  • The singularity glows in the middle; the collectors glow with their heat.
  • Smoke at the controller warns of hot collectors, violet sparks of low stability.
  • A starting or running reactor radiates up to 4 damage per second at its centre.
