So after spending quite a bit of time trying to figure out where in the heck induction coils were, then finally reading the post and seeing that it was just simple metal blocks, I finally attempted to get the turbine working. I was able to get a single iron ring working around an 6 blade tall vertically oriented turbine, which even at 1800 RPM generated no energy, so I then tried taller ring (gave error of all metal blocks not being in ring or partial ring around turbine, even though they were just stacked on the valid ring), and from that point forward, NOTHING worked, not gold, nor aluminum (playing a modified FTB Techworld just adding the RC1 of this), not even reverting back to the original single iron ring, all gave "## invalid blocks, must be metal blocks in ring or partial ring" error message.

Do you have any blades on your rotor? Please include a screenshot when you're having trouble getting something to assemble.

Subsequent error message

At this point I've tried everything BUT completely rebuilding the entire turbine multiblock. as you can see though, If i remove the iron, and replace my access port, it works fine, just generating no power :/

This is user error. The metal blocks can only be in the 8 spaces directly around the rotor (in your case: north, northeast, east, southeast, south, southwest, west, northwest), and they must be placed further from the rotor bearing that all of the rotor blades.

This is something I intend to document better prior to the final release. :)

So after trying several configurations still no go :/ Maybe something demonstrating it a bit better?

Also tried filling in all the empty spots from the first one, I've literally tried every combination surrounding the rotor I could think of, even the one that HAD worked initially fails

You need to place the metal blocks DIRECTLY around the shaft (not around the blades!) - and (in your setup) ABOVE the blades.

Quote: "Note that these metal blocks must be further from the rotor's bearing than all of the rotor blades."
This means, that the blades must be between the bearing and the metal blocks.
