Age of Steam
Age of Steam moves power through shafts and gears instead of wires, adding axles, gearboxes, crankshafts and generators for NeoForge.
What it does
Power in Age of Steam travels as mechanical energy along connected axles and gearboxes, so no wires, FE or RF are involved. The core mod runs a simple real-time physics calculation for acceleration across each network and a separate stress calculation for every part, and parts break when they are overstressed.
The mod adds the basic transmission parts: a motor that converts FE into mechanical power, a hand generator, wooden axles, a linear gearbox with a 4:9 ratio, a T-junction gearbox and a four-sided distribution gearbox, both at 1:1, and small and large crankshafts. Ancient Warfare 2 Generators is included as an addon, along with woodmill, millstone, sieve and spinning wheel machines, improved fluid pipes and a mechanical pump.
Age of Steam requires ARLib, which must be installed alongside it. A server running it needs every connecting player to have it too. Files are published for NeoForge 1.21 and 1.21.1, and the latest file is 1.0.25 for 1.21.1. The code is not open source; it is covered by All rights reserved.
Key features
Mechanical power network
Axles and gearboxes form networks that carry mechanical energy with simulated acceleration.
Part stress
Each network part has a stress value, and parts break when that value is exceeded.
Motor and hand generator
A motor converts FE into mechanical power, and a hand generator produces it directly from player action.
Gearboxes
Linear, T-junction and distribution gearboxes transfer power with fixed ratios between shafts.
Crankshafts
Small and large crankshafts add two sizes of mechanical component to a network.

Use cases
Mechanical factories
Builders can connect machines through shafts and gearboxes instead of cabling them.
Addon machines
The bundled woodmill, millstone, sieve, spinning wheel and pump run on the same mechanical network.
Who it’s for: Players who want automation without wires and FE, and server owners who want a shared mechanical power system for multiplayer worlds.

What the author says
Age of Steam is a mod about tech and automation in a slightly different approach.... There are no wires, no FE/RF. Everything is done with mechanical energy transmission.
