gollark: I also go for the common thing of having giant battery buffers but also overengineering power generation enough that they never actually get used.
gollark: I mostly work with RF, so my stuff uses, generally... NuclearCraft fission/fusion systems, weird closed-cycle power systems using trees and whatnot, solar panels, that sort of thing.
gollark: Addons?
gollark: Because I once blew up an entire base that way with Gregtech.
gollark: You've never blown up a machine from feeding it 128EU/t instead of 32 or something?
