Here a new beginning.
a mission statement from Nelson ...topic under construction

Quote I would like to greet the OU community and introduce a mildly controversial theme. It is directed
towards researchers of Tesla's bifilar pancake coils.
My intention in returning to this subject is related to performing experiments in the past with a
specific oscillator I developed some years ago. Interesting results were obtained with some good
practical applications, such as a resonant dielectric transformer-inverter.
No claim is made in any particular way, but rather there is a wish to develop something practical as
a functional system. A system of use to the community and documented to be easily replicated by
community users. An aim, is also to evaluate the efficiency of such a system with correct
measurements. That is the main goal of this topic.
Here are some introductory points related to bifilar pancake coils:
Tesla, within a patent relating to their use explains that bifilar or double pancake coils are able to
store many times more energy than single wire coils.
Bifilar coils maximize the voltage between turns.
Tesla assumes that this type of coil has a voltage gain.
The energy within the coil is condensed into negative and positive components of current.
He calls this system a capacitive system of electrostatic nature, where only a small amount of
charge moves through the load per cycle.
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.
The displacement current is a back and forth of bound charges in the nonconducting dialectic
materials, similar to capacitors. A bifilar pancake coil is capable of holding electric charges like a
capacitor.
No work can be performed when operated with a displacement current, but if a large quantity of
voltage displaces small amounts of bound charges, work can be performed on loads such as a
filament bulb without the conduction of current.
Modern thinking considers displacement current as false current, different from conventional
current flowing in a conductor wire. However, Tesla understood the meaning of what constitutes
current, like Maxwell did:
"All charge is a residual effect of the polarization of Dielectric and that variations of electric
displacement evidently constitute electric currents."
Another aspect characterizing this coil is when a bifilar pancake coil operates in resonance, the
distributed capacity is able to overcome the counter force of the inductive reactance.
Because the electrical activity in a pancake coil works against itself (counter EMF) the potential in
the coil raises naturally to higher values. Almost all of the energy stored within a pancake coil is
transformed into full potential.
Summary - pancake coils could act as specific electrical energy storage systems, storing energy in
their dielectric.

My intention is to deepen this theme, which lay forgotten in the "drawer". I would like to count on
the participation of enthusiasts, those interested in contributing to this project in a constructive way.
Since it is a controversial topic, I would appreciate persons with animosity towards the subject
refrain from comment, in order to maintain a healthy ambiance for others.

This topic will be moderated by me, maybe others too, in order to ensure that the rules of good
coexistence are respected.
I hope there are moments of joy within the involvement of all participants.
My thanks!

Well, I am excited. I also research this subject and it is very difficult to find sources of good information.

Displacement current is controversial perhaps if only because the term was introduced as way to satisfy certain assumptions. It took a lot of research to even figure out what the controversy was exactly. Not that I wish to reopen that can of worms here, but I've struggled to find the best terminology to describe this subject matter.

The way I see it, there what we call electricity which typically describes a method in which we use differences in the distributions charged particles to produce work. Then there is this other thing - which seems to arise from potential changes propagating faster than the electrons. This "other thing" has been called a displacement current, Radiant energy, etc. and is a bit of a fickle. It seems to have its own rules, figuring out what these rules are has been very challenging. I look forward to learning and sharing.

It will be great to see you share your methods here Nelson! Good on you for taking that step in the Community Direction!

I hope the Community is up for a little bit of a challenge, they may just benefit from a little bit of hard work!

I wish you the best of luck Nelson! Some are more than ready, some the opposite. Yin Yang...

Some advice if I may, monitor your thread reads, keep a running count on it.

Best wishes, stay safe and well my friend,
