About Mekanism
Mekanism is a classic tech mod with a clear progression path. Ore processing goes from doubling to quintupling, and the late game adds fission and fusion reactors, digital miners and the MekaSuit.
It moves gases and chemicals through pressurized tubes, which makes factory layouts interesting to plan.
Configuration
General settings, including radiation, are in the config/Mekanism folder. Server values apply per world or server.

Radiation is a real mechanic. Contain waste properly; server owners can turn radiation off in the general config.
Frequently asked questions
How does ore processing scale?
Each tier adds a machine. Enrichment Chamber gives 2x, Purification Chamber 3x, Chemical Injection Chamber 4x and Chemical Dissolution Chamber 5x.
Do I need the Generators module?
Mekanism machines need energy. Generators provides Mekanism's own power sources; you can also use power from other mods.
