welcome to the forums
this has been talked about before but here goes
btw is optimized for ssp
ic2 is made for smp
as a result btw can do a lot of artsy stuff that would kill servers. ic2 devs wont implement this not because they are lazy or are to dumb like you are implying but because this mod is optimized for multiplayer. its a case of function over form.
a new high output windmill will also not be implemented because "the one gen to run the shop" position is reserved for the end game nuclear reactor. if you do not wish to adapt then here are your options
1. use the ugocraft mod to build something that looks like a working windmill
2. get flowerchild to get off his high horse and reintegrate forge into btw so we can use crossover-mods
3. pay a programmer to make a mod for you
EDIT: also repeating previously denied suggestions like this is frowned upon here please use the search button next time to check before posting
