Jim Murray’s Drummond Island Experiment Replication Attempt
« on: September 29, 2017, 03:03:05 AM »
I decided a few weeks ago that I wanted to replicate Jim Murray's original experiment that he conducted in Drummond Island, Michigan where he oscillated the power between an 800KVAR Synchronous Capacitor and the  Local 6,000KW Diesel Powered Generating Station.  This was the first time he achieved what he calls "Energy Resonance".  This experiment was conducted during an ice storm where the main electrical power grid links were down and the synchronous capacitor (SC) was on an isolated circuit with the stand-alone diesel generator.  Jim said that when he changed the reference frequency of the response on his SC regulator to ignore the line frequency and take an artificial frequency of twice line frequency that the load went off the generator while the town of Drummond Island still was lit up with power.

A few years ago when I was working with Eric Dollard, I was inspired to build a machine for the purpose of experimentation with phase locked harmonics. The machine consists of an electric motor, timing belt, timing cogs and three alternators.  See pictures.  It would seem that this machine should be fairly effective at attempting to replicate Jim's Drummond Island Experiment.

The alternators are all modified.  The field-winding regulators have all been bypassed and I have direct access to the slip ring brushes to feed the field with whatever signal I would like.  The rectifier sections on the outputs of the alternators have all by removed.  All of the alternators are wired to generate from a three phase WYE configuration.

The timing cogs are of differing harmonic gear ratios so that I can study the effects of phase locked harmonic modulation in systems.  The cogs that I have allow me to investigate the first, second and third harmonics, and I have intentions of getting a cog that will allow me the fourth harmonic.  These are all arranged and chosen according to the needs of the experiment. 

Each of the three alternators have individual functions.   The first alternator is the Power Alternator (PA).  This is used to simulate the generator at the power plant.  The second alternator is the Modulation Alternator(MA).  This is used as a source with which to modulate parts of the system with respect to the Power Alternator, such as Magamps or Synchronous Motors’ Field Windings.  The third alternator is being used strictly as a Synchronous Motor.  This synchronous motor is used in synchronism with the Power Alternator and modulated with various experimental harmonic signals with varying levels of DC Bias.

In the Drummond Island Experiment, Jim supposedly changed the response of his Synchronous Capacitor's regulator to create a beat frequency of 120 Hz with the line.  He said that as soon as he dialed in on this frequency that his friend running the generating station reported the instruments to indicate a no load condition at the diesel-motor generator’s shaft, this all while the town of Drummond was still consuming power.  I wish there was a good write up on the internet about that experiment, but the only place I know the story to be told is on the Murakami/Lindemann conference videos.  Unfortunately, that is not free information for the public.  "Tesla's Hidden Discoveries" goes in the greatest details of the account.  Maybe someone knows of an internet reference out there?

I have been trying to replicate this phenomena but have not been met with success yet.  I'm a little unclear on how Jim is actually modulating his system.  In his Dynaflux Concept video, he says “created a beat with the line frequency of 60 cycles in such a manner to bring the total frequency up to 120 cycles”. But in his Tesla’s Hidden Discoveries video, he suggests that he is modulating the regulator with the second harmonic which would have to result in he main line current at the fundamental and third harmonic.  The two different interpretations are as follows:

#1) The synchronous motor is creating a beat in the main line current of 120 Hz.  For this to happen, the synchronous motor's field winding would need to be modulated with another 60Hz wave.  The lower and upper side band frequencies are as follows:

Fbeat-LSB = F2 - F1 = 60Hz - 60Hz = 0Hz

Fbeat-USB = F2 + F1 = 60Hz + 60Hz = 120Hz  ---  Second Harmonic in Main Line Current

#2) The synchronous motor's field winding is being modulated at 120Hz, thus producing a beat on the line at both the first and third harmonic. Upper and Lower Sideband math:

Fbeat-LSB = F2 - F1 = 120Hz - 60Hz = 60Hz      --- First Harmonic in Main Line Current

Fbeat-USB = F2 + F1 = 120Hz + 60Hz = 180Hz  ---  Third Harmonic in Main Line Current

So it can be seen from above, that modulating the circuit with the first harmonic will give rise to a beat at the second harmonic.  Modulating with the second harmonic will give beats at the fundamental and third harmonics.  I am still very unclear on which Jim was actually using but have a couple of other sources that suggest the Odd Order Harmonic Series as being the route to investigate.

In his Law of ElectroMagnetic Induction writings, Dollard suggested investigation of the second and fourth harmonics because the sideband frequencies produced by those harmonics line up naturally in the Odd Order Harmonic Series.  Erfinder has also harped on the proper phasing of Odd Harmonics in order too achieve novel effects.

A quote from Eric Dollard from the above reference:
Two particular harmonic modulating frequencies are of interest, the second harmonic and the fourth harmonic. For the condition of second harmonic modulation the frequency of the Lower Sideband is equal to the carrier frequency, these two combine in a resultant wave at the carrier frequency. The Upper Sideband is the third harmonic of the carrier frequency and super-imposed upon it creates a regular harmonic waveform. For the condition of fourth harmonic modulation the Lower Sideband gives the Third Harmonic of the carrier wave and the Upper Sideband gives the Fifth Harmonic of the carrier frequency. The odd order series, one, three, five exists here and again super-impose upon each other producing a regular harmonic waveform. All other harmonic modulating frequencies, three, five, etc, give rise to an irregular sequence and thus produce irregular harmonic waveforms. The depth of modulation as well as the Angle of Hysteresis both have a considerable effect on the resulting waveshape. This can give rise to very complex waveforms. It is to be noted that for large depth of modulation, and high orders of modulating harmonics, that the resulting E.M.F. can greatly exceed the E.M.F. of the reactance coil in reaction to the carrier frequency of the external A.C. current source. These processes are worthy of Experimental Research.

So as it stands, I am spending most of my efforts looking towards the second harmonic modulation of the SC field.  I want to try the fourth but have to get a cog and have it machined to fit the shaft of the alternator.

I have tried various loads but have not seen any evidence of reduced power consumption by my prime mover for any of the modulating configurations.  However, there is still room for investigation.  I have yet to try a delta three phase generating configuration.  There are different magnetic flux properties inside of the cores between the DELTA and WYE configuration so that is something for for experimentation.

One of the drawbacks of this machine that I have built is that the Modulating Alternator is on the same drive belt as the Power Alternator.  This makes differentiating between the loaded alternators a bit more difficult.  The reason I didn’t worry about this during initial investigation is that if Jim was able to oscillate the power in a local system where the synchronous motor’s field was being energized by the very same electrical line that his synchronous motor was supposed to be regulating, then I might be able to get away with a small amount of modulating power from the Modulating Alternator and still see promising results.  As it stands to get any sort of amperage modulation depth into the SC’s field winding, I must step the voltage up from the MA.  The transformers I’m using are home-made and are kind of power hungry for what I’m getting out of them.  I need to find a better transformer solution to this, otherwise it would seem like it takes more power to modulate the system than any additional gains found in the PA.

One idea I had for this was to parallel resonate the field winding.  Unfortunately, the inductance of the field winding to capacitance storage coefficient at resonance weren’t going to give me a very strong oscillation from the low voltage produced by the alternator.  Again, I would need to step the voltage up in order to resonate with any sort of meaning.

I have attached some diagrams that show scope shots with FFT analysis of the various modulating arrangements.  You can see the various harmonics produced and distorted waveforms.  Although I didn’t mention modulation with the third harmonic, I have attached an image showing the resultant waveforms from it since I had the cog lying around.

If anyone out there has done any serious pondering on what Mr. Jim Murray was up to during that experiment, I’d love to hear about any ideas or insights you might have regarding it.  I’d do my best to incorporate anything that sounds relevant and return my results to the forum.  Two of the Tesla inspired icons have hinted at this direction with rotating apparatus so I’m going to continue plugging away, trying various loads and arrangements until I’m all out of ideas. 

More to come..
