So now we're looking at a centrifuge for redstone, a centrifuge for copper, a centrifuge for rubber, some kind of rubber farm, a wiremill, and energy to keep all these going to get a mediocre amount of energy.
I think at that point just slapping down an MFR woodfarm, (induction) furnace and basic generators will give you a lot more bang for your buck. Or going magma crucible>lava engine+geothermal. Or going mfr sugarcane farm > fermenter > still > generator. Or a LOT of other methods that both make more sense than creating single-use batteries to use in your power plant and are easier and more effective.[DOUBLEPOST=1377004630][/DOUBLEPOST]Edit: And it's not even really to get a mediocre amount of energy, it's to turn the always useful redstone into a mediocre amount of energy.
