Was playing around with the new Industrial Turbines in creative, and was curious to see how large they could get.

17x17x32 was the biggest I could get to form successfully. That's with 58 blades, I noticed the turbine code has a variable for a max of 28 blades, but it doesn't seem to be enforced.

I then tried building a 19x19x35, and crashed with
java.lang.StackOverflowError: Ticking block entity at net.minecraft.world.World.func_147438_o(World.java:2522) at mekanism.common.multiblock.UpdateProtocol.isViableNode(UpdateProtocol.java:294) at mekanism.common.multiblock.UpdateProtocol.loopThrough(UpdateProtocol.java:56) at mekanism.common.multiblock.UpdateProtocol.loopThrough(UpdateProtocol.java:227)

Thanks for pointing that out, should be fixed now.
