Pulling energy from the ambient energy field using a coil capacitor

[dieter]

Before I start a new test I have to find a toroid core somehow. I currently can't spend money for this so I'm looking around for a subsitute. Maybe somebody else around here has an idea about what could be used as a toroid core substitute at low or no costs? thx.

Note: Woopy's video shows that the 6V lamp dims and the primary current increases to 90mA when the open ends of the coil capacitor are shorted together to create a transformer.

This was good and informative result. I will try to explain it briefly here though it is in the pdf. Before the wires are connected the oscillating magnetic field that occurs outside the wire is pulling in the energy from ambient. This magnetic field that is created by oscillating electric field disappears when the electric field disappears. When the wires are connected together it creates electric current in a closed loop circuit and the electric field is gone. Hence direct energy flow from the ambient ends and you get normal transformer behavior instead.

dieter:
I forgot to answer your coiling question. Think in terms of polarities. There is no energy flow between wire ends of different coils that have the same polarity, unless there is a short circuit. I am sure any kind of winding will work. Highest electric field is created when you simply keep the winding direction the same all the time. Turn offset will increase the electric field and adding layers will do the same. The more turns the output coil pair has the more it can pull from the ambient. Resonance will possibly improve this so that the amount of turns can be reduced significantly.

danas:
woopy used about 70 meters of wire as primary, 58 volt pulse at 6.3 kHz and air core. If you can use similar pulsing frequency then one option would be to make your first system by winding the coils around the circumference of the toroid. Ten meters of 0.3 enameled wire will fit nicely around the M-088 and I believe it is more than enough as a primary coil. If you can use a coil former then you can easily test your system with and without core.

Capacitance between output coils would be useful information in any replication.

Higher voltage GDTs generate less heat than several low voltage GDTs in series. You could also use open air gaps as a starting point.

It should not matter where the primary is wound with respect to secondary.

A capacitor that charges itself up from a magnetic impulse.

That's the coolest thing I have ever seen.  WooHoo!

Boy, I don't know how or why the gatekeepers let you slip through the crack Jack,
but the genie is out of the bottle now.

Muchas gracias.

Hi Dieter,
Maybe you can find a tv ferrite yoke for free...
It may be a good core for this project. One other great thing is they usually came with lots on magnet wire!

Dog-one, i understand you have replicate it. Can i ask you what you use for the oscillation or the primary? Thanks!

I have not much spare time righ now but I will replicate this for sure!

Nothing fancy, just the basics.

*  NST rectified with about 51 nF of capacitance
*  Primary is just turns of 14 gauge solid wire on a smaller former placed inside the output coil
*  In the middle of the primary is the open air spark gap

The lamp does glow, not bright and is well under unity at the moment.
The ferrite rods must be inserted to get any glow.


At the point where I'm at, the concept looks sound to me.  The main issue I think I'm
having in achieving higher output is the magnetic flux of the primary.  I think the magnetic
field is mostly circulating the wire and not spreading out into the output coil where the
disturbance is needed.  Adding the ferrite rods helps enough to get the lamp to glow.


So my thinking is that I need a way to better get the magnetic field to interact with
the output coil.  Nelson and Evostars probably have the answer by using pancake coils.
With the concept Jack has shared here, using pancake coils would allow the coils to
be placed closely together and since the output coil is non-reactive, the primary would
never see it.  Based on what Jack has mentioned, several pancake style output coils
could be stacked on the primary (both sides), each driving some load.  Too bad standard
induction hobs don't use rapid high voltage pulsed drivers, else we be in business just
using that as our primary and driver system.  Maybe the driver could be tweaked enough
to do what we want for this application...?     Might be worth a look.
