Dang-it EMdevices: That is making sense. Now I'm going to be late to work. :)
So we need to take the voltage across the + and - and adjust it to a certain point to where a device across V and W will breakdown. But that breakdown is only temporary and opens itself up again only to go into breakdown mode again, i.e.; self oscillation.
So at that point do you feel the core material can be iron wire which will have a voltage we can tap into?
Thanks and take care.

now I got to go to work :(

EMdevices, cool. Looking like open TPU of SM :)
BTW, do not forget that square waves or saw-tooth impulse trains are actually AC at their fundamental frequency, just with a lot of harmonics. Actually, I wonder how this coil will transform just a square wave signal.
On the other hand, I can hardly imagine a real-world circuit. They have a ring of 1-2-3-4 coils that does not have "ins" and "outs" yet W and V should be somehow connected to external load or supply, or just to P and N points (kind of local short-circuiting). Should the DC current be collected by winding a third coil on top of all coils, or near 1-2-3-4 coils in bifilar fashion? Still connections W-V vs P-N should be switched somehow - probably by using reed switch that depends on the AC polarity of I-II-III-IV coils. This makes it possible to consider W+P | V+N and W+N | V+P connection states, depending on the AC polarity. Here we have a rotating magnetic field again, and a bit of voltage spikes due to reed switch action. Hall effect switch can be also utilized it seems.

You should change the topic... ;D
Amazing!
The similarity between this and the openTPU of SM is really awesome...

Ok, I'm back, looks like some of you are thinking, that's great !!!
@wildbill, why do you have the rectifyer on the short coils? I would put that on the winding with the many coils, so I can saturate the core easily. (maybe a potentiomenter to control the amount of DC bias is necessary, so we don't push it too much into saturation.
I guess what's not explained in the diagram is the fact that this is the electomagnetic equivalent of a diode bridge, but it's using the one way properties of magnetic saturation rather then p-n junction effects of diodes.
So, you put in an AC signal at the terminals "w", and get positive and negative (with some hash :) ) at the P-N terminals (for Positve and Negative)
Now, some of you smart ones, will have realized the winding in the picture is not meant to be correct based on the right hand rule , but the arrows should be what guides you. Then, if you look at the P-N terminals and imagine you place voltage on these, you will realize that they saturate the core, so in essence we don't need the separate biasing coil. This then almost means what SM said, that the "signal source also becomes the feed for power" or close to it, since we are putting the AC signal at the terminals 'w'.
Anyway, this little device is something that should make us think, and cause us to realize there is a mechanism for DC production from an AC signal WITHOUT commutation and just with magnetics. I believe something simular to this effect is happening in SM's tpus.Â
I plan on experimenting on this as well.

Hi EM: Hope you had a nice and relaxing vacation.
When I looked at the diagram the first time I decided to take the figurative approach and not the literal. But you cannot beat starting with a replication like Wildbill7459's. This could definitely test the theory. Very nice job Wildbill7459. I'd consider what EMdevices said about the bridge rectifier.
I've tried using one of my previously built tpu configurations. A double loop of insulated electric fence wire and a set of two coils wound all the way around the loop configured such that I cut and snipped the coils leaving them in a set of two quadrature configurations in parallel with each other. One coil get connections so that it is continuous and gets the dc bias to saturate the core and the other is where I play.
What attracted me to this circuit is the wheatstone bridge configuration. Normally in R/L/C wheatstone bridge configurations, where all four values are the same, any change on the opposing nodes gets nulled out in the other node set. But when dealing with inductors on a common saturated core the opposite should happen.
Therefore, at core saturation any influence across W and V should see results across P and N. I'm thinking that continuously keeping the bridge out of balance may yeild some interesting results. Perhaps SM's off the shelf slightly modified toroid may help here?
Unfortunately I'm not seeing any results from my configuration as of yet. I went with a 'bifilar' config set up on the coils because it appears in SM's FTPU and OTPU. My coils are copper and I don't know what the core loop material is. It's either galvanized steel or iron.
After reading what GK has come up with it may be pretty important to be able to tell the difference between iron and steel. It appears GK's post, http://www.overunity.com/index.php/topic,3354.msg92475.html#msg92475 (http://www.overunity.com/index.php/topic,3354.msg92475.html#msg92475), and this circuit may be related. One of the copper coils sets may need to be change to steel and I don't think we need to have too heavy amounts of iron for the core.
As IS said 'THE DEVICE OF 1000 STYLES' but with everybody's hard work I'm thinking we're narrowing it down.
Is it just me or are things getting a little weird and nutty around here. Probably just me.
Thanks again and take care.
nap. I will never be the same.
sorry for the plagurising GK

Hrmm rather interesting theory most likely the best theory I have seen so far...
All theories aside according to the TPU videos there was not power placed into the unit though and if there was we already assume that it would have to be something like a battery or something!
