Group: Experimentalist Hero Member Posts: 1808	Quote from: ion on 2018-08-13, 15:42:08 Dear Mike Your observation is correct for a basic tank circuit, however the capacitor in this case is a progressive peak charging accumulator that is not directly involved in the tank resonance, but is inserted into it. In that respect, the accumulator capacitor is not really a factor in the overall resonance of the circuit, this resonance being a function of the self resonance of the coil and the tank formed by the coil, external capacitor and diode capacitance. Ion, actually the accumulator capacitor (nice description) does factor in the resonance of the circuit in the following manner. As the voltage builds in the accumulator cap, the reversed biased bridge diodes that are non-conducting are exposed to the increasing voltage across said cap and therefore the capacitance of those diodes decrease. These alternately reversed biased diodes are in series with the capacitance of the "wire" due to the permittivity of space and along with L1 account for the circuit resonant frequency. Quote The only direct involvement I can think of is the charging voltage on the capacitor back biasing the diodes, thus altering their capacitance, this would be the parametric element, but I could be wrong about this, as back bias may be far less effective than forward bias in changing capacitance. IMO, it is the reverse bias creating the parametric capacitance change in the circuit because the circuit operation requires we see a capacitance decrease which would follow an increase in voltage across the reversed bias junction. A forward biased junction will exhibit an increase in capacitance. Quote If the circuit is redrawn with the stray capacitance of the dangling clip lead returned to the ground of the sig gen, we have a series resonant circuit formed by the stray capacitance of the clip lead and the coil, and the variable capacitance of the diodes, this in addition to the coil self resonance due to it's own parasitic capacitance. The peak detector is inserted in this loop and it's capacitor does not directly contribute to the resonance of the circuit, it's value is too low for the frequencies involved. I agree. As I begin to try lower frequencies, it becomes apparent that a larger area collector (dangling wire) and a larger parametric capacitance (mosfet) would be advantageous. My question is the apparent excess energy due to parametric means, aether means, or both? Right now I'm still trying to clean up the gating of the sweep waveform. All the generators I have supply an asynchronous gate signal for the sweep trigger and continuously output the start frequency!?! In order to do averaging on the waveforms, synchronous gating is required for accuracy. Pm Quote What suggestions do you have for looping the circuit, as I thought the idea I suggested had some merit based on the topology. Maybe if I post a schematic what I had in mind would be clearer. regards P.S. when performing these experiments it is a good idea to elevate the coil with some porcelain standoffs, silk thread or nylon line for consistency of capacitance to the air, as lying on a bench can lead to variabilities in capacitance. I would for consistency also suggest using a tunable "gimmick capacitor" back to the gen ground instead of flying cliplead. A sturdy breadboard with fixed positions for all components should produce greater consistency in measurement.

Group: Experimentalist Hero Member Posts: 2982	Quote from: partzman on 2018-08-13, 16:08:26 Assuming that the measurements are accurate (which is always a question), the negative input IMO means that the excited circuit is receiving energy from some outside source that exceeds the circuit's basic energy requirement. IOW, if the input energy is a positive value and less than the output energy, the COP is a positive value >1. If the input energy measures as a negative value, then we have a negative COP which would be infinite. My initial tests at a lower frequency of 400-600kHz look promising but a more complete analysis is in order to be able to optimize the results.

Group: Elite Experimentalist Hero Member Posts: 4728	Pm Any chance this apparent COP+1 is energy drawn in from local radio broardcast. I just keep thinking-foxhole radio,where enough energy is drawn in to power a small speaker. Is the extra energy you are seeing around the same as what a foxhole radio might pull in ? Also,can this be scaled up ? Brad --------------------------- Never let your schooling get in the way of your education.

Group: Experimentalist Hero Member Posts: 1808	Mike, Thanks! Slider, Thanks as well! Brad, I had considered the effect of some local station or other RF source but a spectrum analysis shows no such activity at least at my bench. I think the device will be scalable but we shall see with more research. Regards, Pm

Group: Experimentalist Hero Member Posts: 1808	Curious to know if this device was really tapping into energy from the aether, I ran a test with a fixed mica capacitor that was connected to ground which was equivalent to the capacitance of the hanging wire or 6pf. The test results were surprising and seem to indicate that if the measurements are accurate, there is no energy being extracted from the aether at least thru the hanging wire. The excess energy appears to be generated in the circuit via resonant, parametric capacitance change IMO at this time. This test was run with a log frequency sweep from 2.3 to 3.0MHz as indicated in the attached schematic. The data table below was produced by averaging the readings from seven separate tests and the spreadsheet is attached below if one wants to see each individual test result. This places this device in a completely different class IMO as it can no longer be called a single wire circuit aka Avramenko/Stiffler. If it is truly functioning as a parametric device creating excess energy, it could theoretically operate at any frequency and would be scalable. It also may not be appropriate for this thread any longer so Professor, you need to comment on this please. Also Chet, perhaps it would be best not to cross post this info quite yet.

Group: Elite Experimentalist Hero Member Posts: 4728	I have been carrying out some of my own single wire power transfer tests of my own in the last week,and have something odd going on with my setup-seems i cannot find a ground-or 0 volt region anywhere on the circuit.

Group: Experimentalist Hero Member Posts: 1808	All, The real question is (as always), are the measurements accurate and real? IMO, this is the next step in that some means must be taken to confirm the measurements. It is really difficult to measure and integrate two high frequency waveforms (voltage and current) at say 3MHz over 100ms. With 100M sample points per second, this is only 33.3 points/cycle or16.6/half cycle. Is this good enough for high accuracy? Shortening the measurement cycle to 20ms with 500M samples per second seems to indicate that perhaps not when comparing the numbers at that point in time between the two sample rates. So, I'm going to spend time to work on this problem before posting any more info until I have some reasonable answers. I would certainly welcome any ideas. I'm also not certain about open (single wire) verses closed based on the above! Regards, Pm

A point on a floating circuit isn't necessarily going to be at ground potential, unless you make it so with a galvanic connection. After all... how is a circuit supposed to have a "virtual", that is capacitive, coupling to ground unless there is an actual voltage differential? Make the connection "real" with a wire and now you're not floating any more. Sort of like a forum... If a forum has an invitation-only membership policy and has secret hidden threads that aren't even available to the whole member list, much less to the public... should we really claim it's an open source forum any more?

Group: Elite Experimentalist Hero Member Posts: 4728	author=TinselKoala link=topic=3628.msg69216#msg69216 date=1534342162] Quote Make the connection "real" with a wire and now you're not floating any more. My point is--that connection cant be made,as no matter from where i connect the circuit to ground,the current draw from the circuit go's sky high-even from the negative of the battery to ground. The device is near 1 meter off the ground on a timber dry timber bench,and built on another dry bit of MDF,so capacitive coupling to the ground is unlikely,as i can only just get a neon to light no more than 100mm away from it,as it is very low powered. Now,if we look at say a 3kVA gasoline generator,they are also a floating unit. But in this case,you can connect either the neutral or active to ground,and no load is placed on the generator,because both are floating as far as earth ground is concerned. Quote Sort of like a forum... If a forum has an invitation-only membership policy and has secret hidden threads that aren't even available to the whole member list, much less to the public... should we really claim it's an open source forum any more? It's more a case of removing the unwanted,unrelated comments and arguments we see on open thread's,where the inventor would just like to concentrate on the DUT,and have a handful of those willing to help involved. Once everything is in order,then it is bought to the open source venue. Things happen so much faster in controlled environments,without the unwanted distractions.

Well, that might suggest that you could put a useful load in between the circuit and ground, at this point. If you can get your _receivers_ to act that way (I can) you're golden. Quote The device is near 1 meter off the ground on a timber dry timber bench,and built on another dry bit of MDF,so capacitive coupling to the ground is unlikely,as i can only just get a neon to light no more than 100mm away from it,as it is very low powered. Pretty much everything between sea level and the ionosphere is capacitively coupled to the Earth and to free space. The neon isn't telling you about the coupling, it's telling you about the strength of the electric field gradient, which may be low but the field itself may have a large volume, hence a large (or at least non-negligible) capacitance to ground. Quote Now,if we look at say a 3kVA gasoline generator,they are also a floating unit. But in this case,you can connect either the neutral or active to ground,and no load is placed on the generator,because both are floating as far as earth ground is concerned. The capacitance to ground is also like a high-pass filter. High frequencies are passed with little impedance, low frequencies or DC are blocked altogether. Quote It's more a case of removing the unwanted,unrelated comments and arguments we see on open thread's,where the inventor would just like to concentrate on the DUT,and have a handful of those willing to help involved. Once everything is in order,then it is bought to the open source venue. Things happen so much faster in controlled environments,without the unwanted distractions. Brad Well, I sure hope it works out that way. Maybe I'm just being paranoid, but if I feel like secrets are being withheld from me, I tend to want to go off and just work by myself. And I think others might also share this opinion.

Group: Guest	Well, if you tease someone with incomplete information, you shouldn't be surprised if they draw the wrong conclusion (or at least not the one you want them to draw.) If I tell you "I saw Jesus this morning, walking down the street wearing nothing but a string bikini"... you'd think I was hallucinating, lying, joking or simply mistaken. But you'd be wrong, because I haven't told you the whole story. Where I live, in the Hispanic community "Jesus" is a common boy's name, pronounced Hey-Soos. And there's a Gay Rights parade going on today. Now you have enough information to draw the _correct_ conclusion, or at least a plausible one that doesn't include branding me a liar or a psychotic. OK, enough. Don't drop something on your foot while you're working -- but if you do please don't blame me.

NOT GOOD I Love what Peter gives us here and cherish the privilege to be a part of that. and the men who come here and elsewhere to give tirelessly of their own time and personal resources, I cannot begin to write the gratitude I have for these men.... simply amazing . and I must add TinselKoala I have gratitude for you too as many here do, your lifes experience is most definitely a benefit to this forum.

It would also be nice to see at least several watts in power level at lower frequencies to help out with the measurements. I'm currently working on all the above so we'll see how it all comes out!

After running more tests, it looks more like the device simply works by resonance of non-linear capacitance and inductance. I can replace the "collector" or hanging wire, foil strip, or whatever with an equal fixed capacitor to ground, and get the same results. I don't think there is any aether magic involved at least at the frequencies I'm working with ATM. Pm
