Did Russ's fancy scope and power factor correction measurements, calculate the actual current value flowing through R2,and hence,the correct power measurements ?

Can you use conventional power measurements for an unconventional system?

Oops you can't attach an image to an email so I am posting this here.

MH

Myself and TK have tested your theory,and it seems to make no difference as to where the CVR is placed-be it at the ground end,or the input as you showed.

Further testing is being done,but at this point in time,either way,the OU result still stand's--until we find that !red herring! hiding some where  ???

The MH test results.

A 100 ohm resistor on the ground side,and a 100 ohm resistor on the input side.

No difference in current measured.

Yep. And in the full Partzman system that I have been testing, I disconnected all probes and then simply measured the Vdrop across the original resistor with the CH2 probe, stored the trace in the scope as Green reference R1,  and then moved CH2 probe and groundclip to the other "MH location" resistor and measured the Vdrop there. (FG is isolated from ground, so no groundloops are created.)

The Green trace is the stored reference trace from one resistor and the Blue trace is the live trace from the other resistor. They overlap almost perfectly so I moved the Green trace up one division for clarity. There is no difference in input current measured in the two resistors.

Seems that you really need go to bench work a bit and make some tests  , and discover by yourself about the questions that you ask , like others do .  Sitting around waiting as someone expects rain is never a good solution.

For sure you will have many things to talk after do some tests about the subject of pancake coil , otherwise like you say you only able hear crickets chirping, because other people are more concerned in working to clarify some of the points of the thread, that call's research  :)
Now if you assume is nothing more to explore on this thread try not be so repetitive about your questions otherwise ,you run the risk of looking a annoying person ask all time the same things .

Why you don't try play a bit with such coils ? even you spend some of your precious time is better than you become annoyed without know in first hand, some of the points that you refute  about any possible advantage of this coils .
I really don't understand such position .  :(

About you say the transformer discussion has pretty much hijacked the real purpose of this thread, i really don't agree with you , because we already change some posts between us about themes like  efficiency of power transfer with this type of coils with a video shot included, but you simple argue and refute saying that a normal transformer  have much advantage in this process of transfer power in relation to a transformer made by bifilar pancake coil , but now you say that a bifilar coil is not a transformer and is only indirectly related   .... this is to i laugh ? what seems to you that ? https://www.youtube.com/watch?v=aEZSCNHDYJs
Is only a coil ?

Do you think people are stupid that not understand what is a transformer and a coil  ? Or you think you are really more cleaver than others  ?
Make something  useful instead of simple create noise, because until now you not add nothing practical and positive to this thread with such behavior.
Do you think you are help anyone at moment ?  To me seems not

Have a nice day

You stop posting crap like this about me.  You can kiss my ass.  I stand by what I am saying and it is true.  Threads get derailed because people chase after one thing and they forget the original purpose of the thread.

It's a nonsense clip that is just "show and tell" for an air core transformer and indeed it's only a bloody coil.  I told you already that a normal air-core transformer will outperform a bifilar pancake coil transformer and I told you exactly why with valid technical reasons.  So why are you showing that useless clip again?

Do you want to improve your performance in your clips?  I suppose that you are not comfortable to speak English in your clips.  Go ahead and speak in your native language of Portuguese.  If you speak clearly YouTube should be able to convert your speech to text and then translate the text into English in real time.  Also do a write-up underneath your clip that states what you are doing as well as summarizing your data.  You can even do that in Portuguese and then we can copy and paste it into Google Translate if we want to.

Kiss my ass with your "have a nice day" BS.  Your whole posting was useless noise and trash talk about me.  Improve your clips so you actually state something of value and you summarize what you did with data.  The last thing we need from you is another clip that says, "Look mom!  I can make an air-core transformer!"

If you want a good suggestion Brad it would be to take a step back and do a slow methodical frequency sweep starting at low frequencies to observe what takes place.  For example, if you removed the center resistor and set your signal generator to say 100 Hz, then it's pretty certain that the setup would be a dead duck.  At higher frequencies, is it capacitively coupling or is it inductively coupling?  The way to find that out would be to look at all the parameters at different discrete frequencies and see what trends take place as you try 100 Hz, 500 Hz,. 1 kHz, 5 kHz, and so on.  You can determine the frequency steps for yourself.

On thing is certain is that as the frequency increases the setup will start to "come alive" and if you carefully monitor things you might be able to determine what effects are taking place and when and how the apparent OU is manifesting itself.  This looks to be a study in the increasing effects of parasitic capacitance and inductance as the frequency increases.  The parasitic effects make it more difficult to do an energy audit trail just like the high frequencies make it more difficult to do an energy audit trail.

I hope that the moderators of this forum are consistent with what they have done in similar situations with other people that use such language.

Hey, you can discuss the project or else you can GET LOST.  I am not here to read useless crap from you about me.

Don't be rude man what crap i say about you ? Did you not write what i point ? Just rewind and see what you write .
 Are you concerned now if i want improve my performance of my clips : ? I'm not concerned about that .. did you already end your dislikes in my videos ? You could create another account and do again that big child . I don't need improve nothing in my videos because even normal people can figure out the message only you with such intellectual superiority not .

I wish you a nice day again to you

My post was removed completely almost immediately....his is still there after 30min....double standards.....
We will see if the Treatment is the same for all ...

Other than the resonance part it is not derailed. I asked Brad to bring back his pizzaz and he did.  If we are going to put this thing to rest it should be done thoroughly. And there is more to do beyond these imagination driven ideas that are being tried right now.  We still have to put pulsing through the ringer. Transformer action between the 2 windings where one is pri and the other the sec.  Someone had proclaimed to me something about the Bedini bifi coil. He said that when the coil fired, you can collect from the bifi drive coil and the trigger coil and that there was more there than was put in. As in, what ever was taken from the drive coil during field collapse, it is unchanged when you take from the trigger coil also. The shown circuit doesnt really provide that feature it seems. ;)   

Enough with the language barrier stuff.


Id say that coil running 'that' motor with an air core with loose coupling was impressive. It wasnt like a string of leds or ne bulbs. Id say by the looks of it that motor is not a flyweight.

Saying "kiss my ass" is not considered real profanity.  And he deserved it.  The last thing this thread needs is this  "Latin bouncer troll" nonsense.

Everybody needs to stay on topic.

Profanity is you insult people and go out with impunity like you usually do .and are you call troll to me ? The biggest TROLL of all times , the guy that only see their own belly button and not accept any critic .

starting with your condescending comment ... the intentionally dismissive "a good exercise"

you are just hunting for a flame war, and now you draw ethnicity and vulgarity into it.!

Not good not good at all !!
