voltaicfractal,
Sincerely i feel some hostility in your answer to Magluvin ,and besides being unnecessary, it does not add anything positive to the theme we are talking. I would like common sense and tolerance prevail among the participants in this topic, because as i mentioned earlier, in the difficult times we are in, respect and tolerance are points of order.
Thank you for your understanding.

My apologies, my response was not intended to communicate hostility. It is not uncommon for people to view brief replies negatively though I'm not sure why that is exactly. We have the word "curt" which describes this, but I don't really understand why people perceive rudeness in brevity.

Hi voltaicfractal,

No problem , I understand your explanation, and we should move forward

I measured bifilar and monofilar pancake coils. Read the description of the videos:

Whatever it is worth, greetings, Conrad

Hi conradelektro ,
I appreciate your sharing, however, the links associated with the videos appear to be defective, as they present the message that the videos are apparently unavailable.
Could you validate that the videos are still available? Would be of great use for this topic. Many thanks

I corrected the links in my post. I posted from my tablet and this garbled the links. Greetings, Conrad

Conradelektro,
Many thanks by your contribution , now the links are working.

In my two videos
https://www.youtube.com/watch?v=fC84W0PIZoE self resonance
https://www.youtube.com/watch?v=spQ9yLdb7v4
I also calculated the self capacitance of a monofilar and a bifilar pancake coil:

Self capacitance of monofilar pan cake coil 10 pF -- calculated from 8.4 MHz and 34 µH
Self capacitance of bifilar pan cake coil 49 pF -- calculated from 3.9 MHz and 34 µH

Well, is the higher self capacitance of a bifilar coil the mysterious notion that "bifilar or double pancake coils are able to store many times more energy than single wire coils"?

Has anyone measured the other claims?
- Tesla indicates that pancake bifilar coil systems convert input energy in potential,
- that the current consumed is minimal,
- they work in a mode of potential variation and the condition in which the current can be maintained is with no translational movement of charges.

Greetings, Conrad

Hi Conrad , hope you goes well

Well, is the higher self capacitance the mysterious notion that "bifilar or double pancake coils are able to store many times more energy than single wire coils"?

Well This will depend on the perspective of the analyst about the word "mysterious" .
The self-capacitance of pancake bifilar coil will depend on some factors, such as the materials used as insulators in the winding wire because their dialectic properties.
Tesla used in their pancake coils a cotton blend in the coating of the winding wire that certainly has different values than those that plastic presents in the winding of your pancake coils and even in mine.
The acrylic plates, which you used to confine your pancake coils, certainly interfere with the values of self-capacitance of coils, so many factors are involved in this process.
This self capacitance in the bifilar pancake coil at resonance show a voltage gain to be several orders of magnitude in relation to single wire coil with the same number of turns, and its distributed capacitance when in resonance, it manages to override its inductive reactance (CEMF), make the potential of coil increase spontaneous.
This is one advantage and is the reason to Tesla say the bifilar pancake coil convert the input energy to full potential .
The current consumed in the coil is reduced because displacement currents is defined in terms of time-varying electric field and not like conventional conduction current, the friction caused by the current flow in the coil is avoided ,in this way losses through heat are reduced.
The magnitude of displacement current in case of steady electric fields in a conducting wire is zero, since the electric field E does not change with time.
This claims, could be understood and studied with help Faraday's and Maxwell equations .
I made some tests and experiments in the past , but they need be made with more rigor and with a more analytical analysis, but I think the link to the video I share can help to understand some of the points that cause some doubts in relation to some points that you mentioned.
I would like to repeat some of these tests in a more controlled and rigorous environment to understand better all this process .
