And I most likely will be able to call him for discussion
thx

Well written paper, I gave it a quick scan, will have to read in depth as time permits.
I searched for the text "power factor" and could not find it in the document. He is multiplying amps X volts for power into the coil. (I hope it was not a "factor" for major error.)
Further comments reserved until I can read it in depth.
Is this the same Jeff Cook that was causing candle flames to "waver" with pulsed coils some years ago?
Thanks Chet
Heres a movie on the topic [and then some]

He states in his video,that he was measureing DC power in ,and DC power out. His comment was-so we dont have to worry about reactive power in or out.
Sounds interesting,now i have watched the video.
Chet,is there a clear picture or explination of how or what configuration the magnet are set up as?
Are they magnetised axially or diametricly?
Size of coil,and wire size?.

I read that he is using pulsed DC i.e. a square wave with a DC offset as input, also a filter used to limit the input to the coil between 35 to 55 Hz. He also talks of "frequencies sent to the coil". (see attachment 1)
Looks like he only measured the DC going to the coil and ignored the AC component (see attachment 2).
Control tests should be performed with the magnets replaced by ferrous or non ferrous materials or eliminated completely, to be sure the motors themselves are not influenced by the magnetic pulses since they are immersed in the fluctuating field.
In light of how low the actual power input is, there is no need for a 500 Watt amplifier, this can be done with a single FET or bipolar transistor so that input power can be very accurately measured.
A killowatt meter on the front of the amplifier noting quiescent and running power would be helpful.
At any rate, this should be dead easy to loop considering the claimed COP.
Summary: The paper contains lots of data, charts photo's etc and is nicely done. It is similar to what we would expect of a scientific inquiry, but there are serious measurement omissions that are important and would negatively impact his final data and claims. Further it lacks control experiments noted above.
Well i am quite supprised he managed to get the magnet to float above the coil at all. This in itself is quite interesting,and I'm not sure how that could be done with a DC input to the inductor?-although the filter seem to turn the square wave into a pretty even sawtooth type wave. But even so,why doesn't the magnet simply flip over to the attracting pole,and stick to the inductors field-why dose it float?.
I have only seen this done using a magnet with the apposing field facing the inductor,and spun to obtain a stable levitation above the apposing field.
I am also supprised that he can produce enough torque from the rotating magnets to even turn the small motors that he is using for generator's-letalone pull power from them.
I agree that the P/in P/out measurements could be off,but by 4400%?. This would be a huge error of measurement-would you not agree?.
Ok ,so i spent some time,and read the paper.
It seems that the magnets are magnetised axially. So how exactly can they rotate while placed vertically over an inductor?.
Next thing i read was the P/in figures to the inductor.
V/in=.27
A/in=.012
This seems extremely low for an inductor with an impedance resistance of 2 ohm,s while powered by an amp?.
To obtain the above V/in and A/in,the resistance would have had to be close to 22.5 ohms-would it not?.
Well i am supprised after some testing on a 12 inch sub i carried out.
Input source was my SG,and settings as followed.
Square wave set at a 50% duty cycle and 2vpp.
off set by 1v.
Frequency 50Hz.
P/in measured with scope.
A=.00152 volts across a .1ohm 5 watt resistor.
V across coil=88mV, with 2.5 volt spikes apon switching.
The speakers resistance is 3.1 ohms.
Ofcourse the PM is still fixed to the speaker,and so that may change the outcome a bit. But i am supprised at how little power is being consumed at a 50% duty cycle. Not to mention that the noise from the speaker is quite loud for these low P/in level's.
I am reaching out to invite Jeff here.
Thank you for looking
Chet

The magnets rotate on a horizontal axis. Still, it seems they should not be influenced by the inductor considering their orientation and magnetization. But how do we know they are the source of energy to turn the motor since no control experiment is shown without the magnets? Could it not be a possibility that the motors are influenced directly by the inductor pulsing? Would the magnets spin if not connected to the motors? These questions have not been answered or included as control experiments.
This should be seriously considered before anyone spends the time or money to build one of these devices. A few simple tests could answer these questions.
I think he measured DC resistance and called it impedance. The impedance at the frequency he uses may be closer to 22 ohms. DC resistance should not be confused with AC impedance.
Well I'm still at a loss as to how the magnets rotate,while having an axial field direction?.
The 22 ohms sounds more likely ION,as that is very close to what i stated in an above post-22.5 ohms.
I am going to build a coil as he states in his paper,just to see if i can get an axially magnetized magnet placed vertically on the inductor,to rotate-this in itself would be worth the setup time.

We both are at a loss on the magnet rotation issue. This would be worth the time to test and shouldn't take that long. I'll see what I can do also.
I have orded the magnet's as specified in the PDF,and started work on the inductor-as per PDF.
The rest i can machine up myself on the lathe.
Im not goint to worry about the motors at this point in time-i just need to see these magnets rotate first.
That in itself will be something new to me.
A pdf by J cook of an error, but not all lost as is seen in reading this

@Centraflow
I think ION was onto this mistake befor you posted the above information.
But it is good to see the mistake was corrected by the inventor.
Thanks for the PDF
