ThermaDucts
by ImEden6
ThermaDucts is a NeoForge transportation mod that lets players build duct networks carrying items, fluids, energy and even players between endpoints.
What it does
The mod revives the duct system of the Thermal Dynamics legacy for modern Minecraft. Ducts come in several families: item ducts, fluid ducts and energy ducts, each with basic, hardened, dense, impulse, vacuum and flux-plated variants, and transport ducts that move players between their endpoints. Structural ducts add support to the network, and the ducts can be combined into pipe networks that carry several kinds of cargo at once.
Ducts are routed with servos, retrievers, filters in five tiers and redstone relays with sixteen color channels, so a network can be steered, gated and controlled from redstone. The duct tiers draw on nine alloys the mod adds with their own standalone recipes, and the metals on that list are built into the crafting chain.
The mod is distributed for NeoForge only, with files for 26.1.2 and the latest build 1.0.2 published on 2026-10-10. Installation covers the server and each player's game. The license is custom and the project is not open source, though its source code is public.
Key features
Item, fluid and energy ducts
Ducts for items, fluids and energy each come in several tiers, with transfer rates rising from basic up to the flux-plated variants.
Player transport ducts
Transport ducts carry players between endpoints, so a network can move people as well as cargo.
Servos, retrievers and filters
Servos push and retrievers pull cargo, while filters in five tiers decide which items or fluids pass through a duct.
Redstone relays
Redstone relays offer sixteen color channels, letting a network be switched on and off by signal color.
Nine standalone alloys
Nine alloys, each with its own recipe, are needed for the higher duct tiers.
