@Terzsian The efficiency of the eletrolyzer can never reach 100% and the limiting factor is always going to be max pressure.But there is hope there is an exploit that prevents it from over pressurizing here’s a picture.There is also another problem with the eletrolyzer it involves the way it outputs it’s gas sometimes the packets of oxygen or hydrogen get deleted due to the way the eletrolyzer works this exploit also fixes this issue as well unfortunately this is the only way you can get a 100% effective eletrolyzer in game.
