You need more energy for your machines? Get an extreme amount of it

Extreme Reactors is the original port of the 1.7.10 mod Big Reactors, by Erogenous Beef, rewritten for MC 1.9.4 / 1.10.x / 1.11 / 1.12.2 and 1.16.3 / 1.16.4 / 1.16.5 / 1.17.1 / 1.18.1 / 1.18.2 / 1.19 / 1.19.1 / 1.19.2 / 1.20 / 1.20.1. The name was changed following Curse Forge deployment rules.

Giants Reactors to harness the power of the atom or mighty Turbines to turn steam into energy? Why not both?

Build huge multiblock machines to produce produce energy in a very efficient way. Extreme Reactor support natively the Forge Energy Power system with the Forge Energy Power Taps so you would be able to power the vast majority of modded machines. The mod is designed in such a way that, if needed, more power system can be supported. Just let me know!

DEPENDENCIES

Extreme Reactor require ZeroCore to work. Please add the correct version to your mod folder.

To use the in-game manual you need the mod Patchouli in your pack.

THE EXTREME REACTOR API

The API jar is available on my maven rep: https://maven.zerono.it/

NOTABLE CHANGES SINCE 1.12.2

Turbine Coils update! (versions 2.0.38 and following)

There are now three new (one is making its comeback) late/end game coils for extracting a huge amount of power from your Turbines: Ludicrite, Ridiculite and Inanite. You should expect around 45K / 75K / 115K FE/t from a full coil in a Reinforced Turbine from each of them.

Mod(-pack) authors can now use the /er coils command to fine tune any new coil they add to ER

The Fluid Fuels update!  (version 1.16.5-2.0.32 / 1.17.1-2.0.32 and following)

Extreme Reactors now support fuels (and wastes) reactants in fluid form that you can insert in your Reactors without any material loss using the new Fuel Injection Port set in inlet mode. Fluid wastes will be ejected into an Injection Port set in outlet mode.

How will you make fluid fuels? With a new multiblock machine: the Fluidizer!

You will need a Controller, a Power Port, an Output Port and the usual mix of Casing and Glass parts (if you like the Glass, right now the fluid is not rendered inside the multiblock). There are two kind of Injector Ports that will let you insert material in the Fluidizer:

  • the Fluidizer Solid Injector for solid ingots or blocks
  • the Fluidizer Fluid Injector for liquid fuels

One Solid Injector will let you convert your solid fuel to it's fluid form

Two Solid Injectors will let to convert and mix two different solid fuels into a new type of fluid fuel

Two Fluid Injectors will let you convert and mix two different fluid fuels into a new type of fluid fuel

Mixing fuels with usually give you a better fuel than the original ones

Please check in JEI for the recipes (more recipes can be added using Vanilla recipe system)

  • All fuels and wastes in fluid form can be placed in the world. It will be probably not a good idea to swim in them
  • Added the Verderium fuel. The top tier fuel
  • Added the Rossinite waste. It will make you go fast like the GOAT
  • Added /er command (op level 2+). Useful for pack authors to fine tune fuel values

**The Fuel Update (version 1.16.5-2.0.29 / 1.17.1-2.0.29 and following)

Extreme Reactors now support fuels reactants that produce fuels with different properties from each other. This allow ER and mods / modpacks to add different kind of fuels using the ER API (FuelProperties / ReactantsRegistry) or the API modpack-wrapper. If no fuel properties are specified for new fuels reactants, the default ones (Yellorium) are used. This will allow the creations of other fuels by mixing existing ones, once liquid fuels are finalized.

Blutonium is back as a full-fledged reactant and fuel, with a better yield than Yellorium (keep in mind that it's properties are not set in stone right now), and it's "crafted" by reprocessing Cyanite.

Blutonium will turn into Magentite, a new waste-type reactant, after being used in the Reactor. There is currently no use for it in the mod, but who knows what will happen in the future.

**The Reprocessor (version 1.16.5-2.0.29 and following)

A new multiblock machine that's able to reprocess wastes into new fuels. You will use it, for example, to craft Blutonium from Cyanite (check the recipe in JEI).
