I have a hard time believing you'll get that level of power (100/tick from 36). I'll run a test later.
Also when I wrote bucket-powered, I didn't mean by hand. That is stupid, considering it can be automated with vanilla buildcraft and vanilla IC pump easily.
They dont produce 1.3 eu/tick average. I havent seen a windgen production go lower than 2 eu/tick. They produce like 3 eu/tick on average. I dont see you babysitting watermills just to get 1000 eu per bucket. You would be better off with 1 windgen on top of the world than having to man a watermill on bedrock level. The windgen will keep producing while you mine your stuff while watermills stop after a short time. I made a pretty nice windgen farm on my old world consisting of 36 windgens which made over 100 eu/tick (that includes the cable losses) most of the time. I rather run a simple wire down to than make a new nerfed watermill farm for energy.
Btw 2 way transposer/filters sounds nice. That would make it possible to make a 4 chamber CASUC reactor with 2500 cooling capacity instead of the 3 chamber we have now.
