I have similar concerns about the MOSFET driving circuits on this as an earlier design that also floated the MOSFET gate drives.  The drive circuit for each MOSFET needs to develop voltage to the gate referenced to the respective source terminal.  If you need to add more windings to your coupled chokes to do that, that is a lot better than having your MOSFETs sit there without switching, or worse burning up.

Hey Dave

Have you tried these inductors with the second winding open ended vs not connecting the open ended winding to the main winding? Just wondering.     seems interesting. Never thought of it before.

I knew you were still around 
No, the idea just came a couple of days ago.
Still waiting on parts got my cores and bobbins waiting on transistors, should have been here yesterday.

I put idea's up for consideration and discussion, give my take on how it works.
Hopefully we will find the answer.

Yep, always around.  Just had to put more time in other things for a bit.

Well, before you put any of these larger circuits together, make your windings on the core and try some basic stuff to see what effects there may be with the open ended winding vs not connecting it at all.  My first thoughts would be that it may be freq dependent, being bifi?   More turns, lower freq.

I have a few bifi coils I can try some things. Cant today.  Simple enough to try though.  Compare operating a single winding alone, vs one end of the second winding to one end of first winding, vs connecting it to the other end of the first winding.

I have some belief that there should be an effect having the open ended winding connected one ended to the primary winding, connected to one end or the other. My lil TC coil, having 1 turn around the top of the open ended secondary lights a light bulb. If the open ended sec of my lil TC can do that, then there should be some definite differences in your primary winding operation when adding the open ended winding into the equation. 

Gota go to work.

Mark thanks for the suggestions am studying them now.

Dave, you are welcome.  The other thing that I see is that there is nothing protecting the A'- node or B'+ node.  The drawing below is one way of dealing with that.

Magluvin, and other ou researchers who are/were wavering:

I think that is a terrible example.  Mr. Ellis is upset because he does not think that the entertainment program "Myth Busters" was fair to John Bedini's false over unity claims.  Did the  entertainment program entertain? Yes it did.  Did it state the real known physics?  Yes, it did.  Did it discuss the real reasons that Bedini's false claims are nonsense?  Yes it did.

John Bedini showed us the way, he didnt give it all away but put us on the path.
His system is a pos boost converter, Id bet with careful consideration it could be made to boost the neg as well.
These are all bemf collection systems, will it go ou, can a coil draw from the ambient 

Maybe we need to give it a source besides the battery to draw from,,,,,,,,,,like an ion cloud

I think its their attitude in the vid and their crappy setup that makes them look like idiots. They dont even try to understand whats happening they give their "we know more than you and you are an idiot attitude" and never really consider the possibility.

Separate the pos from the neg, collect both.

I believe it can be done and will not be discouraged.

That Mythbusters episode is almost ten years old.  I would have thought that if John Bedini could refute it, that he would have.  John Bedini has been making wild claims since at least around 1982 when he published materials that claimed to show an electric German motor scooter that was powered by ambient electricity that was to be available to the public in 1983.  32 years later, he still makes wild claims and no one has shown any machine that John Bedini has claimed as over unity running on its own without running down.

Keep experimenting.  Keep learning.

I think I need to change where the A'- and B'+ diodes return to the configuration below.  The earlier connections would not close a current path for the inductors.  You will want to be careful with the layout.  Stray inductance in any of the current loops shown will develop unwanted voltages when the MOSFETs switch.
