Electrolyzer output

Because all material unit in ONI in mass(kg), not mol. Oxygen is far heavier than hydrogen.

Though I also agree that current situation in game seems quite unrealistic in sense of volume of gas.

In oni only the grams/kilograms a gas weight matter. So in terms of weight the equation can be written:

2 H20(36,032g) =  2 H2(4.032g) + O2(32g)  multiply both sides by 27.75

=> 999,888g(H2O) = 111,888g(H2) + 888g(O2)

So yeah, the game amounts in grams are exactly the right ones. Oni doesnt have a way to handle how dense a gas is and how much space certain amount of gas there can be in a tile. Instead in oni gases just flow on top of each other depending on their "density"
