I saw a chinese guy having a Tesla coil inside a copper tube. Coils do not touch the tube. He had 2 diodes coming from the tube to a cap and the second leg of the cap going to ground. Diodes were setup like a rectifier so one let through positive and the other let through negative.

When he blasted the spark gap he got 800 volts to that cap.

This seems like his setup, but with coils and not a tube

found it!

yeah I saw this video long time ago and its quite interesting, capacitors are connected to copper tube through diodes and that's it (cap does not have any ground-earth wire) tesla secondary bottom wire and upper wire goes to earth (is the earth needed for this ?) tube could act as inductor but it should not charge capacitors just like that.

I have notice something similar, I connected one end of flyback HV output to aluminum tube, this tube is inside a plastic tube and I glued some aluminum foil on plastic tube. When i touch a Led to aluminum foil and when second leg of led is connected to earth (or any metal object) Led light's up very brightly, I already burned out 5 leds by playing with this setup, also led does NOT FLICKER and works in any polarity.

I made a video explaining how to easily make a bifilar coil from speaker wire, and how the fields are situated:

You can stack several of these in parallel, and increase capacitance.

Has anyone experimented with passing permanent magnets
Over a bifilar pancake coil, as generation?

Or is this best done perpendicular?

Take a look at skycollection's youtube channel, he uses them, as a motor, and as a generator:
https://www.youtube.com/user/skycollection

I've been looking into axial brush less pulsed DC motors. like this one:
https://youtu.be/k-dgtUXvRIs
The coils of these coils, can be made from stacked bifilar coils.
And the back EMF can be reused, aswell as with regenerative braking, the capacitor/batteries can charge again.
If the motor would be high speed, very high speed, It might be possible to run them with resonant coils.
But I think that's not really realistic, as the frequencies (motor speed/resonant frequency) are to far apart.

not exactly what I was looking for.
But he shows nicely the motor effect.
I was looking more at driving one from a wind source
Or some other rotational power (sterling, or whatever)


A lot of his coils are multifilar, not necessarily 2
and it appears the lights are in series with the signal generator.
So it is unclear what generative effects (if any) are produced.


The magnet is free spinning, but I believe it is diametrically magnetized.
So it answers half of my question.


I’ll probably have to just wind one and experiment myself.
Never tried, these are usually powered coils.
But, I mean if we do it one way, we should be able to do it the other way.
The same as the receivers, but by generating our own oscillating field
Using permanent magnets.


I’m thinking more in terms of a horizontal transition of the magnets.
Crossing the center.
magnetic field will increase on the way in, and decrease on the way out
which (in my mind at least) seems like the perfect manipulation of the lenze/Lorentz
forces.
Actually it’s the simplistic version, the ideal case would be to approach from 360-degrees
Then retract. (just an idea, I haven’t performed any experiments, and have not yet
                       set up a series of equations to describe the actions of any particular magnet)


The ideal case presents itself with some mechanical difficulties that I’m not willing to tackle
at this time. (iris door?)


So I’m looking at n/s/n/s passing directly over the coil, from a rotary device.
in theory, each winding should act as an individual coil of its’ diameter.
My curiosity is in how it will interact with the magnet.
the attraction force will peak at the center, but as it leaves, is decreasing.
(or in the other viewpoint, the opposing force will be away from the center, then towards the center after)


the bifilar effects show the opposing field will be extended, but still diminishing with radial distance.
As long as the driving force is enough to overcome this, we should be able to generate with them directly.


What these videos DO show, is we can mount his set-up right to a bicycle or large wheel acting as a gear
of sorts, causing the cylindrical diametrically magnetized magnet to rotate
and in this manner it would be the same as my proposal,
but only using the center part of the coil, and not it’s greater outer periphery.


A very very large cylinder magnet, and a coil smaller than its diameter
would maybe work.

That’s a nice 20-amp homemade motor in the 2nd video.
Using lithium batteries it could probably fly.


If you stack bi-filar pancakes, I believe they need to be in
parallel, and have to line up vertically.
I’ve read about that situation from various sources.
Otherwise results in a completely different magnetic field.
With multiple vectoral components.


To increase voltage (in a generator), simply make them larger.
(this is of course within reason of the diameter of your man-made field)
