Interesting Effect On Copper Rod
« on: May 09, 2014, 04:45:11 PM »
I moved this topic to a new thread, as I believe it deserves. PLEASE STAY ON TOPIC!!

Here is a very interesting video published  May 3 2014 from a friend of Stephan Hartmann that wishes to stay anonymous for now.

The beginning shows a 15 Watt lamp being lit normally from the KAP type transformer secondary at about 15 Watts with 14.55 Watts input (29.1V 0.5A). Frequency around 60kHz

The second half around 3:00 is interesting when he inserts the copper bar and ferrite cores and lowers the frequency to around 20kHz. Then with just a connection to one end of the copper bar and one of the coil wires, an extra light is lit brightly without any increase in current drawn from the supply.

The frequency is too low for capacitive coupling to the bar, and the power in does not change with the additional lamp?

The circuit is about COP of 1.0 with just the one lamp, but then two lamps (added 7 Watt lamp) are brightly lit with no increase in power input?

Grumpy take note: If not faked in some way, this could be a demo of the alternate method of getting current to flow in a conductor that SM may have alluded to.

It would be interesting to use a second lamp at 15 Watts or more to get over unity. I usually don't get too excited by circuits that exhibit little no increase in current, because most of them have so much excess power dissipated in the device that some of it is just shifted into a low wattage lamp. This demo is clearly different and superior to most.

True we cannot know the brightness of the lamps and what % power they are consuming. This is just a guess.

The important part of the video is the induction of a current flow in the copper bar. I estimate the coupling capacitance to the first coil layer to be not more than a few hundred picofarad. At 20 kHz, even with square waves it would be very difficult to light a lamp as there is an insufficient closed circuit through the capacitance.

More important to observe is the lack of load reflection back to the power supply.

I can understand if he were pumping in a few hundred watts, it is easy to shift a few watts from some other lossy element into the lamp and not have it show on the metering, but we are talking a power input too small to hide the extra power drain.

Message to the anonymous originator of the video: Thank you for a clear explanation of your findings of this interesting effect. Would you be willing to transfer some build information, schematics etc of your test here? You can remain anonymous if you wish.

Admin: Kindly move relevant replies from other the thread to this thread.

Surprising lack of interest by folks on this forum of what looks like the long sought after Kapanadze effect demonstrated in the lab.

Nothing forthcoming despite a request for more information.

I'm currently setting up a copper rod device and have 30 toroids to work with and will report later if I get any interesting results.

Hi Vortex1,

This is something I have heard from reading about early telegraph operators in the 18 - 1900's when they were using dry cells and trying to boost the signal. They used a copper pipe/sheath to slide/adjust over a keying coil to create a "surexcitation"(?) in the output, their term.

Here is a patent from 1884 that mentions it:

297924 - Apparatus for the production and utilization of secondary electric currents.

http://www.freepatentsonline.com/0297924.html
https://www.google.com/patents/US297924

On page 2, left side 85

Quote
"A bundle of iron wires, f, may be placed in the center of the cylinder, enabling, by means of magnetic surexcitation upon the introduction or withdrawal of a cylindrical copper envelope, the graduation of the intensity of the current developed in the secondary wires."

I tried looking for what "surexcitation" means but the definitions are not related to anything electrical. If you go into Goolge books and type "surexcitation copper telegraph" you'll see some brief references to it but no real explanation.

I guess a simple test is to feed a signal into a coil with a cap and see how sliding a copper pipe over it changes the output. Wonder if this has some relationship to Akula's coil design?

-

In relation to the patent I wrote some code in Octave to try to match a physical test build. 25ft wire with 14Awg wire as the center and 21Awg running parallel to it. Then pulsed with a 16vdc, 6x3000F in series=500F ultracap bank @ 40hz with a mechanical switch to handle high current. My calculation is off somewhere though, but I attached it here if anyone is interested.

HI, my two cents.

I remember vaguely reading a pdf about Leedskalin's explanation about magnetism.


He gives a documented example how to make the strongest electro magnet. By inserting the coil and iron core in an iron pipe, one end capped.


The principle might be the same, but not sure if it would amplify it.
It might be you direct it.  (as a laser)  into one direction, thus create a higher efficiency.

Today I setup a basic Zatsarinina transformer experiment with a 12mm outside dia copper tube with 17 off 3E25 ferrite toroids. The inner copper rod was connected each end to various loads. The drive circuit is as shown below. The purpose of the experiment was to test load sharing effect on input current as prompted by this video.

My first test was to run a second wire conductor through the tube for a second load. Both loads were 12V filament lamps. Connecting the second lamp dimmed the first but showed no change of input current, as was observed in the video. My next test will be to insert the ferrite assembly into an air coil with multiple windings and conduct the experiment as shown in the video.

I'm kinda new to OU stuff, but isn't the setup behaving as a transformer?
Were those toroid transformers that where stacked along the copper rod that was inserted into the big coil assembly?
Anyway, it's very interesting and doesn't look like it would be too expensive to duplicate.

Very Interesting.

Please someone post the schematic here. I can not get to it from where I am. (long story!)

Yes, it is a transformer.

Yes, the ferrite toroids on the copper tube are inserted into the coil assembly in the video.

Hi Hoppy,

Thank you for posting this.Recently after reading the Don smith China replication as found in page 260 pjkbook.pdf ,One of Don smith video and this schematic.

I have now 100% concluded this is running on RF power.The nice circuit you posted is a rf transmitter as well.The advantage is low amps is required.My recent video of electronic stimulation as posted in Don smith topic revealed that it merely consumed around 20mA on 1600v(1600v emulate the capacitor bank).

I have attached the Don smith device China which is running on <10KV and using RF power for the 5 turn induction coil with the LC should match their frequency 220khz...230khz.
(OMG BU508D is a 1500volts transistor)
Example my 5 turns 3meter oxygen free 8AWG cable is at 2.65uH capacitor to use 0.19uf 10KV to get around 224khz.(Outer diameter with 8AWG wire is just below 3inch) :)
Online L/C calculator-http://www.deephaven.co.uk/lc.html

My first objective is to assemble using suitable toroids,copper sheet,copper wire as rod(I do have spare 999 silver rods in one of my fav health product for use with distilled water :) ).
Then i need to start making large printed circuit board on my own in the meantime while waiting for parts arrival. :)

Hi Vortex!

Just to clarify:
you wrote:
>The beginning shows a 15 Watt lamp being lit normally from the KAP type
>transformer secondary at about 15 Watts with 14.55 Watts input (29.1V 0.5A).
The 15 Watt lamp had an output of apprx. 3-5 Watt in that moment (camera does not give real view) and was connected to L3 in that moment!

>The second half ...  an extra light is lit brightly without any increase in current drawn from the supply.
But what not could be seen in the video is that the 15 Watt lamp dims in that moment
(output power is beeing divided in that moment)

>The circuit is about COP of 1.0 with just the one lamp, but then two lamps (added 7 Watt lamp) are brightly lit with no increase in power input?
From the visible light emmission i estimated an output of about 3-4 Watt from the 15 Watt lamp plus apprx. 6-7 Watt from the 7 Watt lamp.
So stating an efficiency of about 80% should be realistic.

Just forget the 15 Watt lamp connected to L3 and focus on the 7 Watt lamp on L1

BUT: How efficient is a regular light bulb at 20 kHz? I do not know!
I tried diodes, but mine are not fast enough, which decreases output a lot - i even have very slow ones which completely cancel the output.
I ordered ultrafast diodes for a full bridge - will post results then.
Problematic is the high voltage peak on the output: Even with an attached 7 watt load a get up to 1.5 KV on L1 (output)
Diodes with high voltage and high speed are not easy to get (and to manufacture of course)

So the next step is to lower the windings on L1 like Dally (Kapanadze Cousin) does by winding 5 turns copper foil as L1 - we will see if  the effect then still remains.

One more thing: It is important to NOT capture the high voltage back emf back to source or into a cap or another coil. This "FREE" sharp HV spike is essential for the effect of "NoDrawBack" - so watch out for your FET to be able to handle this high voltage spike. I added a diode in front of the FET which saved FET lives thousand times (killed dozens of this $10 pieces). I am not sure why the additional diode protects the FET from death - i guess the Trr of 40ns is responsible - for me this just works.....

Happy experimenting

BTW: I am updating additional infos here to have important things together at one place:
