A cyclic assembler (with power) or liquicrafter (with a clock) should do the job for ya. I just made a barrel full of fresh water once and never made any more again. You'll need a bunch of water for it of course, probably from dynamic tanks and a rain collector.Hey Anesos. I remember you mentioning in one of your episodes how to automate fresh water, but I can't find it. What was the method/episode?
Love your show,
And I guess I'll mention that once you've killed the End Dragon, you can craft an aqueous accumulator and create water for free, but my dynamic tank setup seems to be more than sufficient anyway.
