Realistic Generators

Most power mods hand you a block that makes energy. Realistic Generators hands you a process — fuel → heat → steam → rotation → electricity. Build it well and it hums. Build it wrong and it tells you why.

Realistic Generators — multiblock steam & nuclear power

Power you have to engineer, not just place.

Most power mods hand you a block that makes energy. Realistic Generators hands you a process — fuel → heat → steam → rotation → electricity — and every stage is a real, buildable multiblock that behaves like the machine it models. Build it well and it hums. Build it wrong and it tells you why.

How it works

A complete steam plant is a chain you assemble yourself:

  1. Fire a boiler to turn water into high-pressure steam.
  2. Pipe the steam through a turbine — a rotor you build stage by stage (HP → IP → LP).
  3. Draw off Forge Energy for the rest of your base.
  4. Condense the spent steam back to water and run it as a closed loop.

Physics that actually bite

These aren't decorations — every lever changes your output, or whether the machine survives the night:

  • Pressure is real. Over-fire a boiler with nowhere for the steam to go and it ruptures. Fit a relief valve, or watch your gauges. Run it dry while hot and the thermal shock bursts the shell.
  • Heat has mass. Machines warm up and cool down — no instant on/off. Cold starts are slow and weak; a hot plant is efficient. Turbines spin up and coast down on their own inertia.
  • Carnot efficiency. Bigger temperature gradients extract more work (η = 1 − T_cold/T_hot). Superheat raises the hot side; a condenser pulls the cold side down. Run hot, condense cold.
  • Assembly order matters. A rotor runs HP → IP → LP in order. Get the order wrong, leave a gap, or orphan a stage and the turbine makes zero power — and the dashboard says exactly which stage is stray.
  • Sized to match. Every multiblock is variable-size. A boiler too small starves the turbine; too big backs up pressure; a battery too small overloads and melts. A coherent chain is a build puzzle.

Every multiblock has a controller with a live dashboard — temperature, pressure, load, output, efficiency breakdown, and a plain-language diagnosis the moment something's off. A built-in Patchouli guidebook teaches the whole chain in-game.

A UI you can actually read

Every controller opens a full readout built for the job — not a single number on a block. Bars, gauges, stage maps and a one-line verdict at the bottom tell you what's happening and what to fix, at a glance.

Steam Boiler — firebox heat, live pressure gauge, fuel burn and economizer. Hit the limit and the relief valve saves the shell.Steam Turbine — efficiency reads as Load × Carnot × Spin, with live HP / IP / LP stage assembly.Battery Bank — charge level, overheat and coolant tracking, plus per-pack cell health across the bank.

Plays well with your whole modpack

Nothing here is a walled garden. Interop is through shared standards, so it slots into big packs — built and tested against All The Mods 10 — without conflict:

  • Forge Energy (FE/RF) out — any mod's cables and machines pull straight from a generator.
  • Conventional c: tags for fuel and materials — coal, diesel, uranium, dusts and ingots from any mod just work.
  • Fluid capability for water in / steam out — accepts water from any source.
  • No hard dependencies. It cooperates; it doesn't demand.

What's in v1.1

The full steam chain: multiblock boiler, staged turbine, energy storage, condenser, controller dashboards, and the in-game guidebook. Variable-size multiblocks — scale them up for more throughput.

Coming next

Nuclear. Reactors with the same realism contract — coolant you can't skip, meltdowns you can earn, spent fuel you have to store. Same interop, same c: fuel tags, same turbine.

No sounds yet — want to help?

Right now the mod ships completely silent — no boiler roar, no turbine whine, no relief-valve hiss. The machines are begging for a voice. If you do sound design and want to help bring these plants to life, I'd love it — reach me on Discord at benware_.

Requirements

  • Minecraft 1.21.1
  • NeoForge 21.1.x
  • No other mods required — but a fluid & item piping mod (e.g. Mekanism, Pipez, XNet) is strongly recommended for moving water, steam, and fuel between machines.

Early release — tell me what you think

This is the first public build. The machines work; the balance (burn rates, melt thresholds, efficiency curves) is what I most want feedback on. Open a comment with how it feels in your pack.
