Describe the Suggestion

The main idea is being able to produce, store and manipulate gases using either copper fluid tanks and tubes or a separate tube system.

Like with fluid tanks, there could be various gases to use involving:

• methane/biogas obtained in biogas chambers
• coal gas obtained during coal coking
• oxygen theoretically could be obtained from iron perchlorate ore (could be found in nether) thermolysis
• air from overworld atmosphere
• hydrogen sulfide from nether atmosphere(?) or somehow separated from biogas
• carbon dioxide obtained from calcite, dripstone or limestone thermolysis

Biogas fermentation would also yield fertilizer, coking would yield coke (that is, a fuel), iron perchlorate thermolysis would yield raw iron and calcite/dripstone/limestone thermolysis would yield lime.

Some of the uses for gases could include:

Methane and coal gas:

• Bunsen burner (substitute (sort of) for encased fan with lava)
• Stove burner (substitute of Blaze burner in steam engines, or could be combined with iron sheet to fry food)
• Oxygen/methane burner (substitute of Blaze burner, one would give heat level of 4, steam engine boiler powered by nine of them would rotate at tremendous speed of 196 RPM)
• Gas turbine (rotational force source and encased fan at once, could be 1x1x1, 5x3x3, 12x7x7 or 15x9x9; would provide enormous stress capacity, comparable with steam engine, but would already spin at 128 RPM and would need to be spun to be powered up).
• When released inside of a closed room, would cause explosion if an entity holded a torch, or there were lit furnaces (includes smokers and blast furnaces), candles, torches, campfires, Blaze burners or fire, or an entity walked on carpet or on/past a wool block

Oxygen:

• When released inside of a closed room, would promote regeneration, but would also deplete hunger faster, increase the speed of spreading fire and fire damage, and enable combustion of normally nonflammable blocks, such as diamond block

Air:

• Pneumatic piston
• Pneumatic arm
• Pneumatic press

Hydrogen sulfide:

• could be mixed with oxygen to create sulfur, that could be combined with latex (collected from debarked logs) to make vulcanized rubber
• When released inside of a closed room, would cause poisoning.

Carbon dioxide:
-When released inside of a closed room, would promote crop growth and would extinguish fires, but would cause most entities to asphyxiate to death, except for iron golems

Of course, there would be gas equivalent of fluid installations, such as portable gas interface, gas valve
I think that gases could be mixed, but it might turn out unstable or difficult to program.

I only don't know how a gas pump could work

(a very bad) concept of (unnecesairly oversized) gas turbine

Additional Context

I don't know how to represent gases and burner flames
Should burners have an animation or should they release particles instead?
Should ceratin gases be found naturally as deposits in caves or would it be game breaking?

Maybe gas pipes and containers should be made of iron?
