c85. As promised, baby's first metal refinery is up at the top. I originally was gonna use a loop, but I decided instead to run the ph2o through the refinery once, which will guarantee a temperature >0c, then go through a sieve to feed the quad hydra.
Directly below the o2 prod, we've blueprinted in a) the cooling line for the o2, whose outflow *also* sends water to feed the hydra, and b) the top of the drecko ranch.
