Hello, would it be possible to add for this mod compatibility with https://mods.factorio.com/mod/sei-fusion-reactor ?

It is for Space Exploration and independent from Space Age mod, therefore it's plasma is different item from SA plasma and SA resources, used to make the ducts, are unavailable.

Hey there,

I am open to adding compat for overhaul mods but I can't play everyone of them. If you could suggest a
A) research cost and requirement and
B) crafting ingredients
That you find balanced for SE I'd happily add that!

Resourcess can be derived from the modded reactor and general material usage.
20 Tungsten plate => 10 Heavy girder (reduced to balance out new resources)
20 Superconductor => 20 Superconductive cable
10 Quantum processor => 10 Quantum processor
50 Fluroketene (Cold) => 50 Cold thermofluid -100°C
+ 10 Refined concrete (any SE building uses some construction material)
+ 10 Heat shielding (anything dealing with heat or cold uses heat shielding)

It should be made in normal assembling machine, in the same category heat pipes or nuclear reactors are.

As for research, since SE is not aimed at expensive research, rather complex one instead, I would give it 60s x 500 of Automation, Logistic, Chemical, Rocket, Space, Utility, Production, Energy 3, Material 3.
Position should be after the Fusion reactor research, or if it is for some reason not possible it could be after Quantum Processor and Superconductive cable just like the reactor is.

If you have some other questions, I'll be happy to answer them. If you want to test the change before releasing, you can send me a release candidate for testing.

The mod just had an update bringing it to energy science 2 and material science 1, this also means new recipe is needed.

10 Heavy girder (se-heavy-girder)
20 Holmium solenoid (se-holmium-solenoid)
10 Processing unit (processing-unit)
50 Cold thermofluid -100°C (se-space-coolant-cold)
+ 10 Refined concrete (refined-concrete)
+ 10 Heat shielding (se-heat-shielding)

New position in tech tree needs to be adjusted a bit, since it now requires only Holmium solenoid (se-holmium-solenoid), Heavy girder (se-heavy-girder) but it added new requirement of Cryogenic plant (cryogenic-plant) from anither mod of the same creator.
Tech to unlock that reactor is Fusion reactor (fusion-reactor).

science packs:
{"automation-science-pack", 1},
{"logistic-science-pack", 1},
{"chemical-science-pack", 1},
{"space-science-pack", 1},
{"utility-science-pack", 1},
{"production-science-pack", 1},
{"se-material-science-pack-1", 1},
{"se-energy-science-pack-2", 1},

If you wnat, I can send you minimial save for testing the compatibility with all mods in the mod list.

Hey there! The SEI dev made a compat patch and I removed space age as a dependency and pushed it today so we're now compatible!
