Brine is always giving 40C Water through Desalinator. We need it to give the output at the same temperature as the input. Salt Water is doing this already. so not clear why Brine is doing this
Also, we need the Electrolyzer to output gases at the same temperature as the input water temperature. At worst case, it should be some temperature higher than the input water (if we want to make the game harder). Giving flat 70C O2 and H2 is not right.
