Oh my God, I thought I was close to breaking into the electrical age since I have managed to get a bit of aluminum from slucing all of the bauxite to make a dynamo and an electroyzer, so I went to test it in creative. It seems you can't electrolyze bauxite without a *high voltage* electrolyzer. How are you supposed to get there without being able to get enough aluminum to make a dozen dynamos? Plus the transformers. I noticed that red granite says it electolyzes for oxygen and aluminum, and I could use the oxygen in the sodium persulfate cycle to process the bauxite even more efficiently than electrolysing it ( takes less bauxite for each aluminum ), but NEI states that it needs 96 EU/t, which I thought I could get from 4 amps at 32 volts, but it doesn't seem to work. Oh, the LV electrolyzer maxes out at 64 EU/t, so I guess only 2 amps.
Am I missing something or is this frigging impossible?
So, for starters, you can always get more aluminum from the sluice. And you can get sodium from certain sources to get a little aluminum out of your bauxite. And bauxite ore is pretty common - if you run low, you can find more.
...Also, what do you need all that much of it for, exactly?
(Much the same philosophy works for climbing the crucibles: just keep sluicing.)
I'd call the iridium crucible for chip fabrication is the real hard step, but maybe that's just my luck in (not) finding the right materials.
