SourceBlock
by dreamCat
SourceBlock is a Forge and NeoForge utility mod with blocks that produce unlimited water, lava or milk, and blocks that destroy fluids, energy and chemicals.
What it does
Placed source blocks supply an endless amount of water, lava or milk, so a player can run a pipe or a machine from them without a finite tank. A separate empty block and a void block take fluids in, with an internal capacity of Integer.MAX_VALUE, which is 2,147,483,647 mB. Input is discarded rather than stored, which makes these blocks useful as a disposal point for waste from a factory.
The void blocks also accept energy in FE and RF units, and gas, slurry, infusion and pigment chemicals from Mekanism. Each type is removed from the network when it arrives, so load on a line that carries surplus can be reduced. The mod is open source under the MIT License, with a public source repository and an issue tracker.
Files target Forge and NeoForge, with builds for 1.20.1, 1.20.2, 1.20.3, 1.20.4, 1.20.5, 1.20.6 and 1.21.1. The latest Forge file is 1.2.1-forge+mc1.20.1 for 1.20.6, and the latest NeoForge file is 1.2.0-neoforge+mc1.21.1 for 1.21.1. Both loaders are covered by the same set of builds.
Key features
Infinite source blocks
Source blocks for water, lava and milk output an unlimited supply of their fluid into adjacent pipes or containers.
Void and empty blocks
Fluid input to these blocks is destroyed, so surplus liquid leaves the system without a tank.
Energy and chemical disposal
The void blocks also remove FE and RF energy and Mekanism gases, slurries, infusions and pigments.
Waste disposal balancing
Discarding excess input keeps a production line from backing up when an output is not consumed.

How it compares
Sourceflow Infinite is open source under the MIT License and is also published for Forge and NeoForge, so its loaders match this mod. Mekanism: TrashCube is open source under the MIT License and is a trash disposal block set for Mekanism rather than an infinite source. CaoPlus is Forge-only for 1.20.1 – 1.20.6 under All rights reserved and is server required with client optional, so its environment and license differ from this mod.
