This DDOC outlines the R-ANGL Tokamak Fusion Reactor, an engineering/atmospherics machine that facilitates the creation of new gases, adding mechanical complexity and depth to the process of gas synthesis.

I was heavily inspired by Baystation's R-UST Tokamak as well as the downstream Hypertorus Fusion Reactor. I think both are cool, however for upstream I'd like a reactor that facilitates reactions in the tile space and ties in to previous Atmospherics devices. As such, here is what I'd like to attempt to implement Upstream.

A large component of the TEG's problem is the lack of interesting gases and the means to synthesize them. Tritium is synthesized as a by-product of burning plasma at specific conditions, leading to a free large heat boost that invalidates any sort of care for efficiency or optimization - the most people are worried about in that sense are making sure they didn't invert their burn chamber ratio.

Gas synthesis gameplay is generally boring. Frezon setups are largely copied from external sources or reconstructed from memory - there is no intuitive way for players to discover frezon synthesis. Additionally, the only two relevant gas reactions (tritium and frezon)

Oops. Just wanted to put something up

Seems like a very cool idea, but the wording of the document leaves some room for doubts on the purpose of the engine.

  1. From my understanding of the text, this is a machine used to create gases, using gas reactions. However, this is repeatedly refered to as an engine, and compared to the TEG, who's purpose would be to create power. I imagine its both of those things, but the power generation aspect is not mentionned at all.
  2. Now this is on the gas reaction part, since currently we only have freezon, tritium and water vapor as reaction creatable gases, someone might think of the reactor as a replacement to gas miners. It could be, but I dont think this is the intent of the author
  3. Failure state, now since it sounds like the reactor has a very conceptually in depth failure state, it could come to overshadow the singularity / tesla, like how the TEG currently does (though because of different reasons).

Thanks for the review. I forgot to clarify that the goal for the reactor was to serve as the manufacturing point for more powerful gases to be used in the TEG. The reactor will also generate a lot of heat from the confined reaction, so it can either be sent to the TEG or radiated away to space as a way of reducing the pressure inside confinement.

I feel like introducing more synthesized gases to the game will be a precondition to this otherwise cool concept.

Good thing I'm willing to do that :trollface:

Actually, when I made PR that makes tritium better fuel for radiation collectors, I found that radiation collectors can have function to change gases to other while being affected by radiation, I even tried to experiment with that, but it didn't work. So maybe we can also use singularity (or super radio active artifact from sci) for production of some exotic gases

I think only problem, if it's gonna be used as thing to abgrade TEG, is that we don't really need to upgrade it, because like, almost all stations don't need more than 200-300kWt so +- normal TEG setup with solars can power almost all stations. So we need something that can use that extra electricity, for example, we can have like power seller that will sell power so engineering will have actually have a reason to build 10 tesla set ups. or some industrial mining drills that requires like 50kWt to just run, and will produce some ores as output, or whatever other super powerful mechanisms that will use a lot of energy that you can imagine

I plan to make the Tesla and Singularity more engaging in other forms (gases are a part of it) but for now I'd like to try out an Atmospherics engine that is more engaging than moving heat from one place to another.

I think only problem, if it's gonna be used as thing to [upgrade the] TEG, is that we don't really need to upgrade it, because like, almost all stations don't need more than 200-300kWt so +- normal TEG setup with solars can power almost all stations.

The general goal for the R-ANGL is to provide Atmospheric Technicians an engaging mechanic that introduces and facilitates gas synthesis.

Right now the current gameloop is to setup a burn chamber for the TEG and just run it off of that. Doesn't matter if you use up all of the plasma because there's a lot to be used and it usually isn't used for much of anything else - the only attractive gases to make are Frezon via Tritium and even then there isn't much going for it other than selling it or huffing it. It isn't used in any attractive crafting recipes for Engineering and there aren't any other gases to synthesize.

With the R-ANGL, you're likely going to be producing new gases. The gases are TBD but I'd like to sit down with workgroup members and discuss gases that aren't just "reagent but in gas form" and "oxygen but better". Charged Electrovae is a gas that we're interested in and we'd like more gases that are as engaging as it.

The biggest byproduct of the R-ANGL is, funnily enough, a lot of heat. After all you're likely going to be creating a lot of it in the process of fusing new gases, and as such, you're encouraged to siphon this heat off to the TEG in order to help keep the reaction from stressing the confinement field. You can also just waste this heat off into space - and gases like Frezon will help you with this.
