PhysicsProf Steven E. Jones circuit shows 8x overunity ?

[JouleSeeker]

Hi Professor and ALL;

I am new to the site, but am experimenting with Dr. Jone's circuit for 8X overunity.  Have tried several coils with the circuit, but so far no gain above unity.  Am waiting for the specified torroid ferrite core to be delivered so am compatable with his design.  I did notice a small steady state DC current being used by the circuit I have, which I assume is being accounted for, as well as the AC pulses centered around zero.   If I ignore the DC, I get the 8X gain, otherwise less than unity.  Am a bit frustrated by this so far, but will keep trying.  I have a EE background, so can follow most of the discussion.  Any help would be appreciated.

Welcome to the discussion, albertouno.  Can you provide a circuit diagram for your build? -- this will help in trying to understand differences.  Also, does your scope have the multiply function, and are you using it to provide the power = V(t)*I(t) waveform?

Finally, if you will perform the capacitor/time test on the Input Power for your build as delineated above, one can compare the Pinput for your build with other builds.  This will help us determine whether or not your build is "in the same ballpark" as my DUT and Nul-pts builds (for example).

@Gyula: Thanks, Gyula -- I see you found the answer.  Yes, both nails have the SAME windings, 30 turns all-together.

EDIT:  Just found your photo in Reply #785 in which the two windings on the two nails can be seen in 'a correct angle)  and now I think your bifilar winding has 15 + 15 turns i.e. 30 turns alltogether, just like the single winding on the other nail.

This is not my work but I thought someone should look at it.

Thanks Joulseeker for your suggestions and offer to help.  My scope does not have the multiply capability for showing power.  I tried to attach a copy of the schematic of circuit being used,  which is appears essentially identical to yours.  I thinkt the 1 inch torroid is the recommended one, with 9 turns of #22 guage wire.  Inductance TBD.   The base resistor was 56k and 100pf fixed cap, plus variable cap to get 150 pf total.   2N2222 transistor.used (tried several).

Per your suggestion, I did the capacitor/stopwatch test.with a 10 farad supercap. The circuit output resistor was 1000 ohms. Note 10,000 ohms causes scope probe to affect LED brightness.  Test voltages were 2.84v at start, 2,58v after 5 minutes, 2.35v after 10 min.  I get 23.5 mwatts after 5 min, and 21.2 mw after 10 min.  This seems too high for getting overunity.  All scope and voltmeter probes were disconnected during test, except at indicated times. The output after 30 min, with 1.70v input, was series of pulses across resistor of 5v peak and 2 us period.   Led was very dim.   

Calculating output power is a challenge.  Maybe heat some distilled water with the output resistor is a small container?  Any suggestions on reducing input power?  I didn't have much luck using a pot on input return leg  as shown in your video.  The circuit did jump into a strange higher voltage mode at output when input voltage exceeded 5 volts.  Are component values very critical for getting overunity?

  OK -- now for results, as promised.

Attached, we observe the Hall-probe readings for the bifilar-wound coil on the left, and the single-wound coil on the right.  The current through both coils (connected in series) is 3.0 amps. The two readings are repeated, as shown in the second attached photo-pair, showing that the readings are repeatable. 

Recalling that the ambient field reading is 1.0 mV (see above), we have:
B-bifilar ~ 3.2 mV - 1.0 mV = 2.2 mV
B-single ~ 1.8 mV - 1.0 mV = 0.8 mV.

Consistently in these experiments, I have found that:
THE BIFILAR-WOUND COIL GIVES HIGHER B-FIELD READINGS THAN SINGLE-WOUND COIL.

Since both coils have identical currents and the same number of turns (30 in these cases) and the same cores (nails from the same box), I do not understand the physics that causes the bifilar-wound coil to have higher readings, consistently.  But that is the observation.

As a scientist, I would like to see the experiment tried again (and again).  In particular, I would like to use a calibrated Gaussmeter for the comparisons.

@JimU -- I have borrowed a good LCR meter to take capacitance C measurements -- an MCP BR2822 meter.  The meter measures C at various frequencies.  At 100 and 120 Hz, C values are ZERO for both the bifilar and single-wound coils.  At 10 KHz, I get 104 uF for the single-wound and 122 uF for the bifilar -- so the bifilar is higher, but again, my measurements of B were taken with DC current (where the capacitance as measured would be zero or close to it).

It is interesting that the measured inductance L values are different also,
Single wound, L = 10 uH (@100 Hz), 1.9 uH (@ 10 KHz)
Bifilar wound,  L = 11 uH (@100 Hz), 2.4 uH (@ 10 KHz)

@albertouno --   Your Pinput values seem reasonable, although somewhat higher than mine as you read back through the thread.   

Measuring Poutput is much more difficult, given the high-frequency oscillations in the Poutput waveform.  I measured Poutput using the scope's multiply function on V(t)*I(t)  [output] -- as delineated above.

Since your scope does not have that function, you will have to use some other means.  Measuring temp rise in a small amount of water as you mentioned is one way, basically a simple calorimeter -- but it would have to be calibrated in some way (perhaps with a resistor and a known energy input from a cap). 

As I mentioned above, I was quite excited when a colleague would allow me to use his sophisticated calorimeter at the university; but he then grew very reluctant to allow me to put a circuit into his calorimeter...  So at the moment, that effort has hit a wall... 

Meanwhile, I am looking into other methods for approaching OU also which are taking time -- and teaching me a great deal!  In particular, looking at the Gabriel device and the Tesla/Smith/Zilano device.  These approaches have the advantage of scaling easily (if they provide OU!) to output powers in the kilowatt range.    Lots of fun!

[JouleSeeker]

   I should add that a VERY good way to show OU is to loop output power back into the input... not so easy in this case, but Nul-Pts has shown a path for doing just this. 

His schematic and very interesting RESULTS are given by him earlier in this thread.

Other modified builds were also interesting -- please see the video by Lasersaber:
