Talk:Gases and Liquids

Gas overhaul discussion

Have we discussed/decided how we want to change this page for the gas overhaul currently in beta? There will be a number of various fuel combinations. Perhaps we should just copy over the combustion reactions as listed on the stationpedia below the phase diagrams? Unless, of course, we'd like to try and have a different name for every combination? I can't imagine that's feasible. -NeoAcario (talk) 17:30, 14 March 2026 (UTC) (please sign your comments with -~~~~)

There's been no discussion that i'm aware of. I've been slowly working on Module:Gas with an eventual goal to replace the gas infoboxes with it, though without a timeframe on when the update gets sent to stable i don't know how much time i have left. I'm assuming there's a plan to add a recipe to the Fermenter kit and potentially some sort of machine to extract Hydrogen from Hydrochloric Acid at least, though that could potentially trivialize Venus.
Fuel would need an eventual overhaul but i'm not sure on how to go around it. I've added combustion enthalpy data for fuels on their respective gas pages but not there, and actual combustion energies depend on the oxidizer so describing it isn't a straightforward.

Stationpedia-like combustion diagrams could be added with a new template, but i disagree with its idea to include input/output temperatures. They also don't account for Thing combustion at all and that depends on how long a thing burns for and how much energy a thing generates when being burned(both of which can be unique to each thing, though i haven't seen one of the latter with a value other than 100kJ yet).
There's no distinction between liquids and gases in burn energy calculations, and that would make for very long combustion tables as you'd have to include reactions not just for the fuel in its gas form but also its liquid form for both fuels and oxidizers (even stationpedia only has to include one of these).

To make matters more complicated, solid fuels don't "burn", but rather release gas contents at fixed temperatures. You can feed degassed coal to a solid generator and get no gas production from it.

As for this page specifically, I think splitting it into elements and compounds is starting to become a bad idea as combustions in this game don't have an equal molar balance between inputs and outputs. The oxygen-ozone distinction in particular would make both of them compounds, but doing so would also require moving everything there to that except pollutant and helium. One possible alternative would be separating them into Fuels, Oxidizers, Hypergols and "inerts" but that leaves out molten salt evaporating into pollutant. It could be split into "Other" but that would likely require removing things in the "useful mixtures and other" category. -RA2lover (talk) 18:43, 14 March 2026 (UTC)

I've just implemented a placeholder template on Template:Combustion. For example, you can use {{Combustion|Fuel = Alc, 1|Oxidizer = Liquid Nitrous Oxide, 2 |Output = Nitrogen, 4| Output2 = Steam, 2}} to get 1x = 2x + 4x + 564 kJ

It currently doesn't wrap things in a frame, include combustion temperature or parse representations including numbers such as N2O correctly, but it should be able to do this with further edits to the module. -RA2lover (talk) 21:52, 14 March 2026 (UTC);
