Lol, where's the fun in that? Also I don't think there's that much iron in the whole world... 22k is just rediculous.
The fun is being able to not worry about power gen for a month while I switch focus to AE2 and a base overhaul. AE2 autocrafting would make some of these large builds go a lot smoother. Making 16 iridium neutron reflectors by hand was a pain in the ass that would have been trivial with AE2 autocrafting. I'd also recommend getting that autocrafting going before galacticraft for anybody preparing to head into space.
