About this project
What does Black Start add?
Black Start
**The night is darker. The furnaces are slower. The torches barely glow.**
Build a giant coal power plant, run it, and bring electricity to your world.
⚡ The Coal Power Plant
- Place a plan with the **Project Table** and watch the plant rise **stage by stage** as you supply materials and time.
- The plant interior (boiler hall and control room) is built by the project itself.
- **You build the rest:** place the turbine, generator, heat exchangers, condenser, pump and cooling tower, then connect everything with **pipes you lay yourself**.
- Manage **boiler pressure**, watch the gauges and react to **alarms and faults** before things go wrong.
🔌 Electricity (FE)
- Cables with **+ / − terminals**. Connect them the wrong way and DC will hurt.
- **AC and DC** power, with inverters and rectifiers to convert between them.
- Cables are always visible, so your grid is part of your world.
🏭 From Small to Huge
- Start small: **hand-crank generators, water wheel, coal generator, steam engine, small power plant**.
- Grow into the **giant coal power plant**.
- Later options: **solar farm, giant wind turbine, deep geothermal well**.
- Resource machines, coal processing, electric lights, electric furnaces and more.
🔬 Research
- Press **R** to open the research tree.
- Earn coins from **labs** and unlock new machines step by step.
🌫️ Pollution
- Burning fuel raises **world pollution** from 0 to 100%.
- Higher pollution brings **thick fog**, yellowing grass and **lower combustion efficiency**.
- Fight back with **air filters and air cleaners**, or switch to cleaner power.
🌙 A Darker World
- Vanilla torches and lights are much weaker. Furnaces are 2× slower.
- Nights are darker and foggy.
- Only **powered Black Start lights** keep monsters from spawning.
- You can only sleep with a **powered light** near your bed.
- Villages get weak street lamps, and master villagers need power to trade.
📋 Requirements
- Minecraft **1.21.1**
- NeoForge **21.1.248** or newer
- No other mods required. Needed on both **client and server**.
⚠️ Compatibility Notes
- Shader packs may hide the pollution and night fog.
- With **Distant Horizons**, turn on **"Enable Vanilla Fog"**.
