They are nice, great way to reduce area needed for windmills, although i'm afraid it doesn't have the same EU/t fluctuation as the normal ones does. [0 - 10 EU/t]
If it does, please tell me the source code formula .
OK, I added something more like IC2 EU generation, so it's more realistic. It now also uses the height to calculate its EU output.
Make their area check the same as normal windmills + 2^X (X = tier of compact windmill) on all axis :
ULV would check for 11x9x11
LV would check for 14x11x14
MV would check for 17x15x17
HV would check for 25x23x25
EV would check for 41x39x41
I made it a little bit different, but now it's checking a further area, the higher tier the windmill is.
