What do you guys run in terms of water mills? I don't know if it's just me, but personally I get a kick out of designing the best bang-for-your-buck water mill tower setup. This is the Tower Of Power setup I just finished for my current FTB Ultimate world, I could probably eek a bit more performance out of it just for bragging rights but here's the stats as of right now: 64 unmanned water mills 5 x 5 x 12 dimensions = 300 blocks Power output = 12EU/t Power output efficiency = 75% The surprising thing is that it was actually pretty easy to make the 64 water mills (mind you I'm using the IC2 recipe), so 12EU/t is a decent result considering it'll be a constant 12EU/t all day and all night. A 100% efficient setup would fetch 16EU/t but would be 16 times bigger (17 x 17 x 17). So 12EU/t is about the same as having 24 basic solar panels running over a full Minecraft day and night cycle, but personally I don't like using solar panels when everyone and their brother is doing it.
