So you basically add another wire from the joint at the start of the last leg of the bifilar wind back to the end of the last output leg creating a short or back to the start of the first leg?

We have the man's blessing! ( I was not teasing anyone)

Please do NOT bombard me with questions or PMs. I mean please.

What I have found is that this will only work with multi filar coils.

How many of you guys have watched Thane's videos. How is it that his rotor speeds under load.

I am not telling you how to do this - you can find that on your own, but

What I did was using a 5 x 0.2mm wound coil is seperate and identify the wires.

Use some as normal but try and wire one or two differently.

I used two - start - stop join two more - start stop, just like tesla's coil and wire the last start from the middle of the bifilar join to stop.

Try it and see.

I guess a pic or drawing would be good, but I need to go now.

I will draw one later and post.

Patience and determination.

Thank you.  You may avoid PM's hopefully but I think it's going to be hard to avoid some questions at least. 

I'm having a hard time understanding why Romero didn't mention this in the first week or two as he seemed very forthcoming with help and explanations if he was winding bifilar, trifilar or multifilar - why didn't he mention this before?  Was it your impression this is what he had in his looped setup?  I can understand how this would likely achieve higher voltages as well as less Lenz lugging probably. 

A drawing or schematic will be of great help.  Again thank you for discovering this and checking it out. 

I do think there is just a small concern though with info coming from Romerouk if it is getting too close to what brought about his 'visit' as to whether we can fully trust this is the 'secret' of OU in this device.  But I'm sure some will want to check it out.  If you already have Litz wire I'm sure it won't be too difficult to make some of these mods.  No more difficult than tying nerve endings in brain surgery...   lol

Romero confirmed my guess at bifi coils pages ago.
He also said that normal windings would work also with caps in parallel with the coil. The capacitor would be near single to double digit nf, from measurements Ive done on bifi coils of this size.
But I also explained that the litz wire, if you separate the strands within the litz, and bifi using the strands, the capacitance could get into the upper double digit to triple digit nf.
I would prefer litz with an even no. strands, it only makes sense. Unless Rom used the litz whole and wound a pair of it on the bobbins.

Mags I think I sort of remember that but was he saying that is definitely what he did or that it was a good idea to use in optimizing this?  I do remember he mentioning adding caps and some have done that.  I think the bifilar or multifilar may do more than just adding a cap though.

Well  out of 7 strands, maybe 4 and 3 within could work. But if its just the litz as a whole, then 2 litz 150 turns. then series gives 300 turns. 

Using the litz as a whole, using 2 at 150 turns bifi is the only way that comes close to get 2ohms at 300 turns. ;]

If it were 300 turns of single litz then splitting the strands to bifi, I would presume the outcome to be 4 ohm possibly.

Those that have already a 300 turn litz could try to separate the strands to bifi, for the sake of elimination.

Per Penno's description, I could almost see the wire segments forming a 1/4 wave resonator driving a full wave at its center...where the full wave is actually quad-filer opposed. The frequency would be pretty high, which would necessitate the use of faster diodes than his big bridge. It wouldn't lug, and any output that did happen would be in the Mhz or high kHz range. Seems kind of obscure though. Might just be best to wait for Penno to post a diagram...
