Fuel Gas Synthesis Byproduct is Water

If the approximate intended reaction is CO2 + 4H2 = CH4 + 2H2O, then this process should yield water as a byproduct.

I shall also note another recipe that need correction - the fertilizer from NH3 and N2. The N2 here assumed to be used for HNO3 synthesis internally, but in reality, the immediate source for it is actually NH3 too (N2 is turned to NH3 first, then NH3 oxidized catalithically, and since NH3 is already an input, it may as well be used for HNO3 too). So I suggest either doubling NH3 consumption in exchange of removing N2 here, or add H2 along with N2 (instead of water to not go over the ports limit - water is a sideproduct of N2+H2=NH3 synthesis). Cuz pure nitrogen is impossible to force into oxidation reaction for HNO3 synthesis.

CO2 + 4H2 = CH4 + 2H2O
I very, very want the developers to implement this idea, please .
