Suggestion about bunch of stuff related to each other.

-Disassembling fridge/refrigerator/AC give you refrigerator compressor, recipe: small 1-cylinder engine + 2-liter metal tank + small electric motor + metal pipe (_ICE engine can be converted into compressor unit and visewerse it is not a rocket science_).  
-Refrigerator compressor can be used to make: shop air compressor with receiver, car compressor(_the one you use for pumping tires_), 3-stage high pressure compressor - 3 compressors in seria can result in ~100 bar pressure output, in theory, on practice IRL some people achieve ~70 bar(_liquefied CO2 near its critical temperature_).  
-Compressor can be used to refill pressurized gas tanks, fix car wheels, refill all sort of pressurized cans, airsoft weapon tank, pneumatic tools, pneumo lifter/jack, acetylene cylinders.  
-High pressure compressor refill high pressure gas cylinders: oxygen, natural gas, hydrogen, chlorine, argon, air, nitrous oxide( _laughing gas_), CO2.  
-Uses for gas cylinders: craft “oxy-acetylene bundle”(_basically its 2 gas cylinders strapped together, the thing we use in game to recharge acetylene torch_) for acetylene torch, similar bundle for hydrogen and propane torches, oxygen/air cylinder for diving equipment/fireman gas mask/biohazard suit/breathing device people with “smoked out” lungs use to breathe. Argon for welding, titanium/magnesium/aluminium refining, CO2 for welding. Nitrous oxide for boost IC engines, and as drug/painkiller, oxidizer for rocket engine(_if any ever_). Chlorine - as chemical weapon, damage all living things, plants, make steel/iron rust(_apply damage_). Natural gas as fuel for IC engines.  
-With high pressure compressor and oxygen membrane filter can be made “medical oxygen cylinder refilling device”, it separate oxygen from air and pump in high pressure cylinder, used in hospitals to refill oxygen tanks for breathing(_so device can be found in hospitals or as part of ambulance car_).  
-Also with high pressure compressor, heat exchanger, pipes and valve can be made Joule-Thomson cryocooler to liquify gases(_liquid air, to distill oxygen, argon from it, or liquefy hydrogen(for rocket engine?)_).  
-Liquid gases can be stored in large Dewar storage tank which insulate liquid inside and not allow it to evaporate fast, can be installed in vehicle, can be used to store water and keep it from freezing in cold seasons, or store hot water for long time(_we have small version in game already, flask for keep liquid hot longer time_).

-Sources for different gasses:  
–Oxygen: “medical oxygen cylinder refilling device”, separate electrolysis of water, distilling from liquid air, boiling hydrogen peroxide.  
–Argon: old light bulb(_its there, why not, will need to salvage whole light bulb factory…_), distilling from liquid air(_~1% in air_).  
–Natural gas: bioreactor - made natural gas(methane) from rotting flesh/plants/compost/animal wastes, pyrolysis of wood/waste oil/plastic/diesel/gasoline.  
–Hydrogen: separate electrolysis of water, from natural gas - steam reforming, from ammonia.  
–Chlorine: electrolysis of salt water.  
–CO2: burning charcoal, or something carbonized in enclosed flask.  
–Nitrous oxide: from ammonium nitrate fertilizer, nitric acid.  
–Acetylene: calcium carbide + water.  
—calcium carbide prepare in electric furnace(arc furnace) from chalk/quick lime/calcium hydroxide and charcoal(_graphite initially but baked charcoal can be used too_).

90% will work in RL as described, some i did myself(_calcium carbide preparing most interesting one_), some i seen in person, some i just know will work. So no worries about realism of this all.

PS: cool game:smile:
