Bulgarian MEG Replication

Question,


did you make this video which is on your youtube account: https://www.youtube.com/watch?v=yv53HgiWkmM


Thanks

Hi Luc,
    That shaded pole motors video was NOT made by me. And I just repost it. It was made by a Chinese named "青云" ("Cloud"). He has also made some progress in Donald Smith Device. I believe that the self running shaded pole motors video is a fake.

Hi steadyfield,

Nice setup and instruments! It is good there is no output when you remove the magnet.
I wonder however on the need to change the direction of current in the input coils? from input core saturation point of view
it does not matter.
You change current to reset the B-H curve of the input core?

I ask this because first a half wave rectified current was used by the inventor at the input and he tuned the output coil with
a correct value capacitor to resonate it (so to say to regain the "missing" other half wave), and he still claimed to receive COP >1. 
Of course a half wave rectifier produces DC bias in the core, this need to be considered.
So try to tune the output coil to the input frequency first, (20 kHz) with a parallel capacitor, then try to tune it to 40 kHz and see
how the output power changes. 

One more thing: try to attach a single Neo magnet to the side of the input core to influence its saturation level and see how
the output power changes. Perhaps a second magnet on the opposite side of the core, facing the first 'tuning' magnet via
the core could also influence the saturation even more, hence the operation.

Hi gyulasun,

Thanks for your reply.

I tried changing the direction of the current just by tunning the dutycycle to [50%-2.5%=47.5%] and the effect was the same with 52.5% dutycycle.

When adding one more magnet placed in parallel with the neo magnet (N-N, S-S), the output does increase. However the input current does also increase. When placed the new magnet in (N-S, S-N) with the neo magnet, the output decrease, and the input current also decrease. So I can see a strong coupling from the output to the input.

I tried placing a capacitor in parallel with the load. The output Vrms increased and looked more like a sine wave, however the input current increased. I tried varying the frequency and cannot find a "resonant peak". I didn't try placing the capacitor in parallel with the input coil as I was using a full bridge topology with no inductor connected in the DC Bus.

Thanks Steadyfield for the clarification.
I also believe it is faked and would recommend you not hosting these kind of videos on your youtube account if you want your own research work taken seriously. Support only what you have tested yourself to work.


Thanks for sharing your real experiments and looking forward to more.

Luc,

Thanks for your suggestion. I have removed that video.

Hi steadyfield,

I think the duty cycle should be changed in a much wider range, say from 5% to 50% at least. If you cannot do this
with your present PWM generator, then just build a simple 555 timer circuit like shown here
http://overunity.com/8411/steorn-demo-live-stream-in-dublin-december-15th-10-am/msg243175/#msg243175 
The frequency and the duty cycle can be varied independently from each other.

I think somehow you would need to make sure (as a first step) that the input core should go into saturation.
To do this, remove the permanent magnet(s) from your full setup and insert a 1 Ohm (maybe 0.1 Ohm) noninductive resistor
in series with the two input coils to monitor input current by your scope. Here is a good video on this where
he changes duty cycle and first the input current of the coil increases linearly as it should, then there comes a break
and current starts increasing non-linearly: https://www.youtube.com/watch?v=oDt_Im1TtEE
He speaks Greek language, on his blog there is the schematic for his measuring setup:  http://tinyurl.com/jmrxrxs       

The goal would be to find a low duty cycle (the lower the better) setting with a given (variable) supply voltage amplitude and
input current value where the core goes well into the saturated area.
And when this is more or less achieved, and still there is no output power across the load of course, you could insert
a permanent magnet. I believe your present magnet is very, very strong. I know you tried ceramic and AlNiCo ones too
but now I suggest to monitor the input current when you insert a magnet to see how it influences input core saturation.
I think there would be a certain (unavoidable) interaction which could be minimized by using the lowest duty cycle possible
for a good input core saturation with a given input voltage level.

Do you have an air gap under or at the output coil core? And I assume your input cores are two C shapes facing each other,
without air gap, right? Or you use an E core there?

On tuning the output coil with a capacitor: probably the 100 Ohm load attenuates the LC circuit too much to see the usual voltage peak
at resonance. First try to use some kOhm load (or even no load) to easily find the resonant frequency either with changing capacitors
and / or sweeping the input frequency.
No need to place a capacitor in parallel with the input coil.

I suggest reading member Getca posts in his findings, he reported COP>1 result.

I attached a video, taken from youtube long time ago, that nicely show how permanent magnets can passively cause local core saturation
to create a virtual "air gap" in the core. Unfortunately I cannot remember who uploaded it to give credit to him.

In your video ( https://www.youtube.com/watch?v=Iz4POclJ8ws ) there is still output power when your permanent magnet is horizontally attached
to the side of the lower ferrite bar  and power disappears only when you completely remove that magnet.  This may indicate it is a
very strong magnet for the job? Or too small air gap at the output coil side in the core?  There exists a strong magnetic coupling between
the input core and the output core in your setup
As another test, you may wish to swap the places of the permanet magnet and the input core as per the animated gif file shows in Getca post.
