@milehigh
LOL nice one, I could not decide whether to delete my post or let it ride prior to your last post, in the end I figured it was better to just take my medicine like a man. I apologise for the last post as it was on the verge of a personal attack and that is the last thing I wanted. We should never have to resort to personal attacks to justify our opinions, which I believe I just did in my last post. For some reason I go into "attack mode" when I hear the words "critical thinking" as I have seen little good come of it in most of the forums or society in general. I have done quite a bit of research into critical thinking, Randi.org was one site labelled as the home of critical thinking and what I found there was the most intelligent people I have ever had the displeasure of talking with as there was a decided lack of civility or respect.
In any case, this is another lesson in what not to do and I will make a conscious effort to debate the issues on a technological basis, regarding your first paragraph ---- have you been cyber-stalking me? LOL, I wasn't really aware that anyone gave a damn about what I have posted.
However I would agree with what you have said, I believe in balance and have been wandering as far out in both left and right fields as one can reasonably go I think, from aether theory to quantum mechanics and general relativity as well as everything inbetween. I think I have almost found a comfortable spot near the middle ground which is where I have always wanted to be, you know in all my travels I have found all this mumbo-jumbo has a perfectly valid explanation in conventional physics without exception. I cannot tell you how many times I have proven myself wrong by proving something I never thought was possible, as I mentioned more often that not I am wrong in my thoughts but I have found that is not always a bad thing.
As far as Steorn goes I do not believe they have anything until they actually do but at this point I more interested in what could be possible rather than what their machine actually does. In truth your posts in the joule thief, Rosemary Ainslie thread and others is part of my success because everytime you say it cannot be done I have to find new and creative means to prove it can. As such I am not in competition with you persay but with myself and my own limitations, it is not what I know that limits my success it is what I cannot imagine or will not accept that limits me. In any case I will try to be more polite in the future.
Regards

This posting is a big shout-out to Paul Lowrance:

I just can't keep reading you without responding.  What a contorted discussion there is going on at OU!  It's like scratching your nails across a dirty chalk board while listening to Yoko Ono singing.  Ewwww!  Somebody has to say something!  Think of the children!!!

Quote
Has anyone considered using a relay like Steorn? It seems Steorn likes a few turns, ~ 37, maybe to lower the inductance so as to reduce resonance from the battery. So few turns = ultra low DC resistance. I'm sure there are relays, and then there are relays, right? All relays have ultra low on resistance, but some might have even lower resistance. Also, how about switching speed, as it should be very fast, probably faster than 100 microseconds.

100 microseconds!  Where is your common sense dude?!  100 microseconds is 0.1 milliseconds.  You ain't never gonna see a relay that switches that fast.

Quote
Quote Sean: "Faster in what way - clearly you seem to understand the requirements for current into in Orbo - so let me ask you this - a capacitor can provide a perfectly flat current output - right?"

I think Sean could not be clearer. Although IMO Sean has not clarified the reason. We know that the core has inductance, and we know that if you connect acapacitor to an inductor it resonates. Well, resonance is not a "flat current."  A battery does not resonate no where near like a capacitor, as a battery tries to be a constant voltage source.

"we know that if you connect a capacitor to an inductor it resonates" - There you go Paul pushing yourself beyond your capabilities yet again.  I have read similar statements by you dozens and dozens of times.  You will only get resonance if the capacitor can discharge fully into the inductor so that all of the energy is then sitting in the inductor.  Then the inductor will discharge back into the capacitor.  So you are completely wrong, there is no resonance that takes place in this case.  The capacitor will energize the inductor and incur a very small voltage drop before the circuit is switched off - no resonance.

Sean could not be more incorrect and he is blatantly attempting to weasel out of the capacitor test.  So what if the capacitor experiences a marginal voltage drop when it energizes the inductor?  How will that adversely affect the operation of the pulse motor?  The answer is that it will not affect the operation of the pulse motor at all.  Then of course the energy return from the pick-up coils is supposed to replenish the marginal voltage drop in the capacitor and Steorn claims that there is an excess energy return to boot, so you would need to have a resistor across the capacitor to drain off the excess energy and prevent the voltage on the capacitor from getting too high.  There is a big problem though - common sense tells you that the energy return will be much less than the energy drain and the voltage on the capacitor will drop over time, and you wont even need the extra energy draining resistor.  Don't be surprised if Steorn does everything in their power to prevent someone from swapping out the battery for a large capacitor.

Quote
Capacitors are very linear, and the energy is 0.5*C*V^2.  The battery that Steorn uses is considered drained at 1.2V. Huge difference.  It's well known that batteries are non-linear and do not resonant nearly as much as acapacitor.

Broli is making perfect sense when he suggests using an ultracapacitor.  It doesn't necessarily have to be as huge as an ultracapacitor, but it doesn't really matter.  In a matter of minutes the ultracapacitor would reveal if Steorn is a fraud or if they have changed the world.

"It's well known that batteries are non-linear and do not resonant nearly as much as acapacitor." -  Batteries don't resonate at all, no mater what John Bedini wants you to believe.

Quote
A $50 bcap1500 ultracapacitor has 1500 farads and has as much energy as a 1500mAh battery. People would complain. Maybe if they had a smallercapacitor, say 100000 uF, not that many people would complain, but then again we have the resonance issue.

Poynt crunched some numbers recently for an ultracapacitor and a battery.  The battery in his case stored about 18 times as much energy as the ultracapacitor.  People that understand capacitors would not complain Paul.  You are reducing yourself to a shill for Steorn.  No resonance issue - go and learn something new about electronics.  You can't keep on leveraging your limited knowledge about electronics and try talking the big talk to elevate your stature.  Sometimes you are right in your leveraging, sometimes you fall flat on your face and make yourself look really really bad.  In the latter case you are giving everyone else in the thread disinformation and misguiding them.  It's time to stop overreaching past the limits of your knowledge and go back to basics and continue your own learning process.  Try going on YouTube and watching the MIT electronics courses, they are the real thing.

Quote
The only reason people are saying to use a capacitor is because it does not hold a lot of energy like a battery. A 350F cap @ 1.3V holds a lot of energy.

Incorrect.  Monitoring the capacitor voltage will tell you if the Steorn device is over unity or under unity in a matter of minutes.  It has nothing to do with the amount of energy in the capacitor.

Quote
It would be interesting to do a side by side comparison of a 650 farad ultracap vs. a 650mAh rechargeable battery. I know from my detailed data logging of the bcap0650 (650 farads) that it has a crazy amount of dielectric absorption. That's also seen in electrolytic capacitors. So it's not really true that capacitorsvoltage is an accurate representation of anything until the capacitor has had a long time to rest. For the bcap0650, we're talking about up to ~ 1/2 day of rest time before you can accurately use thevoltage as something meaningful.

Wrong again Paul.  You can ignore the dielectric absorption effects here, they do not affect the monitoring of the capacitor voltage in real time as the capacitor powers the Orbo.  You are demonstrating that you don't really understand what dielectric absorption really means and are incorrectly applying it to the proposed test because you don't want the capacitor test to be done.  You are so anxious to see Steorn succeed that you are putting on blinders and becoming a shill for Steorn.

You don't need to wait half a day.  Your statements above are complete and utter nonsense.  You can monitor the cap voltage in real time and in minutes Steorn's world will collapse all around them and there will be no more investment funds coming in to sustain the cash burn for another three years.

There you go Paul.  Sorry but it was time to put you in your place.  Just like a few pages back I rebutted some of your other points and I noticed that you never mentioned them again.  Before you push the limits of your knowledge way past your true capabilities and make confusing and misleading statements that will be a huge disservice to others reading the thread I suggest you take a huge step back.  Read some books or go to school so that you really know what you are talking about.  The same thing applies to your buddy Gravityblock.  I could rebut his points also and it would be something very similar.

You also need to swallow a huge humility pill for all your swagger about me when I was on OU.  I can't guess the number of times that you laughed with Bill and said "Put MileHigh on ignore, he is clueless and knows nothing."  That was all bullshit and I think deep down inside you knew it when you were saying it.  I asked Bill how his Joule Thief circuit worked and he was unable to answer the question.  I offered to explain it to him and he flatly refused.

These are the kinds of nonsensical shenanigans that everybody would be better off staying away from.  The most legitimate and easy test that Steorn could do for their eOrbo with generator coils setup would be to swap out the battery for a large capacitor.  If the capacitor voltage goes up then they have proved over unity.  No amount of rebutting from Sean or you will detract from this simple fact.

There is no research without analysis and a search for explanations to reveal how exactly it works. As one doing so and arriving to a reason why it did not work it helps the others to avoid the same pitfalls on quest for you aim.  With no critics this site turns into "believers" site sort of religious blog. Otherwise you not aiming to face bitter reality and wanted to stay in the sweet dream.  You will never achieve your aim for real then. If this site really bans analysis and negative outcome of it you call critics then I shall quit. Is anybody wanted to know explanation how "Perpetuum Mobile" displayed in Kinetica museum works? Or you prefer to believe it is a real "Overunity"?

Hi vpo20, and welcome to the site!

No one will ever get banned here for being skeptical, as long as they are respectful. Persons making claims must also be respectful when responding to skepticism.

Also, I'd like to think that we allow all points of view, whether we agree or not.

I agree that without critics, the site would turn into another OU and EF, but on the other hand, without some enthusiasts the site could become quite dull. I think there is a healthy balance, and that is what I'm striving for here.

Both MileHigh and allcanadian are respected members here, and although we all may not always agree on things, I believe our goals are very similar in the end.

Cheers,

Yup, that about sums it up . In fact no reason a 1F or even 1000uF shouldn't work, after all if net gain then any reservoir will just fill to capacity and the system keep running right? 'twill take more than fancy graphics and celtic music to sway me of exotic behaviour.

In fact, there may be many reasons why replacing the battery with a capacitor is a bad idea, one is that a capacitor is not a battery. Another is the inverse square law, with series capacitors the total circuit capacitance of any capacitors connected together in series will always be less than the value of the smallest capacitor. As well energy in a capacitor E=1/2CV*2 plays a role when a circuit having capacitance as a source has coupled in series with capacitive elements such as coils under transient forces invoking the inverse square law for series capacitance. Whenever there is an issue of transient effects due to abrupt mechanical switching capacitance begins to play a major role as we are dealing high frequency electric fields in which lines of force can terminate on any conductors. I once built a small 6v circuit that could electrically charge any metallic object within two feet of the circuit, in fact up to 1/4 arcs could be drawn from any one of the objects to any other metallic object. In this case what we conceive as "ground" or termination of conductors on the source completely lose their relevance. These are the capacitive effects that must be considered when dealing with disruptive circuits and one cannot just replace components without due consideration. I am not insinuating that the Steorn device works I am only stating that consideration must be given to the components used in any circuit.

Hi AC, as far as I am concerned a capacitor can do all that an ionic cell (battery) can do and more. A capacitor with a series R to mimic ESR and a parallel R to mimic internal leakage can pretty well model an ionic cell. An ionic cell cannot match a cap though, mainly because it can't beat its own relatively high ESR, the ionic transport has its own physical frictions that are more pronounced than those found in capacitors electron transport.

If the argument against cap supply is that a cap V will sag too much over the course of one pulse then this is absurd, (this is the argument of the C showing C like effects into an inductive load). Absurd because a large cap like that used in EVs (or even a bank of such to exceed battery joule storage) would  register less V drop over one pulse when compared to the cell orbo runs on, in the real world it will be better DC than a chemical cell.

I also find it interesting that they aren't measuring the open circuit cell voltage before and after the trial, leads me to assume the cell might actually be depleting :o.

Interestingly when you do hit an ionic cell with fast high V transients then the cell will accumulate what many call a "fluffy charge", I myself call it "surface charge", it manifests because the fast V transients are absorbed capacitively by the surface layer of the electrodes, the surfaces then transforms this instantaneous e imbalance into a thin (electroplate like) ionic imbalance, A surface charge can be depleted quickly by applying a load or leaving the cell to "settle" after which time its measured V will settle back down. I have seen this on alkaline, nicad, slab and nimh cells when subjected to bedini like charging, probably lipo will behave the same. This mechanism does have benifits though, it seems that after many cycles of charging like this you can reintegrate the cell materials somehwhat and recondition the battery such that it has a higher capacity, good news!

Just show input and output power waveforms over 2 pulses, that all!, it's well within the bounds of these people, hell they had the necessary equipment right on the bench, nice tek scopes and passive V probes and rogowski coil current propes, those scopes and probes are able to give very accurate RMS in and out powers at much higher frequencies than orbo operates in, what's the *kin problem  ???  hmm let me think.... maybe the problem is they have squat! That's what I'm thinking anyway.

P.S.
Don't assume I'm on some kind of "uber skeptic" trip because I have these ideas, I'd be thrilled to bits if steorn did convince me, I really would! I also hope many ways of getting a free ride are possible, and I will continue to hunt for them. of course I'll still keep watching the steorn show.

@darkspeed,

which video were you referring to? link says invalid. (in the youtube embed feature of this forum just enter link as appears in browser, I once tried the youtube embed code and got same error)

If it´s the video where they were scoping input V and I and showing no back coupling under load then that is not impressive in my mind. The same can be accomplished with a slipping clutch arrangement in a mechanical system when tuned to just under slip. Of course the same can also be accomplished electronically in close to saturation mag couplings.

Their delivery style is quite strong though I will admit that, great PR, great equipment, but lacking real substance.

edit: witsend, was aetherevarising right? rose? so she´s left... she´ll be back I´m sure.

Yes it does make sense but it made me realize that if it does have the ability to do work in excess of its input, it will most likley be at high rpm.

If self destruction was not a problem, unloaded, at what rpm would it settle out at ??

I would guess very high

There's no OU there if that's what you are thinking.

It's just a highly inefficient pulse motor that was brought to a higher efficiency point with the addition of the toroid magnet.

I never discount anything until I can see test data, but in general I would agree with you..
   
Group: Guest
I agree. In order to find a gem in heap of rubbish one need dismiss a lot of false stones. 1000 things must be criticised away until you meet one you could not.

That means the serious analysys cases are 99.99% dismissing "critics". I would avoid termin "critics" completely as more applicable to art and literature and associated with human emotions.  We better call it "analysis" and no emothions should slip in it. Most of analysis bound to be negative but feeling about it is positive as we has eliminated one more rubbish case on the road to first ever true OU.

At the end of  the day there is one only one convincing method to prove it: fully isolated close circuit with excess energy produced in form of heat and run for a time clearly enough to exhaust enclosed sources of energy.

One remarkable example: There is somewhere in one of British museums running an oscillator – swinging pendulum for more the 150 years. It was already running for unknown years at time when it was purchased by the museum. It is fully isolated, contains a 2000 volt battery and it was invented allegedly by Michael Faraday.

If we don know about battery we may thing it is an OU device, however it produces practically immeasurable heat  and very little sound.  I have estimated battery load as 2 nanoamperes. So in 150 years it has consumed from the battery about 10 coulomb of electrical charge, which is 20 kilojoules of energy.  One D size alkaline battery may hold  three times more energy then required to run this “mobile” for 150 years.

I have made such toy myself 20 years ago. Warning: high voltage batteries can kill. For safety several megaohm high voltage capable resistor advised to be connected in series. It did not impact performance at  all.

It will run also on 500 V but require more tuning and a protection from air circulation in the room.

Anybody interested in description please post me.

Some comments about Paul's preliminary COP measurements with his Orbo replication with full acknowledgment that they are preliminary and subject to change.

Quote
Holly Smokes!!! I just did some quick COP measurements, and when subtracting electrical resistance losses, it is showing my tiny "orbo replication" is way over COP 1.

Not sure what you mean by subtracting electrical resistance losses.  The electrical resistance losses would count as part of the Joule heating output.  You may be fudging your COP calculations because of your subtraction.

Quote
If that's not enough, I am not even considering that nearly all of the energy that goes into inductance can be captured back, at least according to Steorns recent inductance measurements on their Orbo. So lets take that into consideration -->

You don't have to take Steorn's word for it.  In their first demo you can see how the current waveform is about 95% flat when the Orbo is up to speed.  That's the part where the coil is dissipating heat resistively.  The energy that goes into the inductance can be captured back, which can be seen on the scope display.  The first 5% of the current waveform is exponential, and shows you where the coil is being charged up.  That's where the induced magnetic polarization from the magnet is "flushed" also.  So perhaps only 2 1/2% of the the total energy that is put into the coil can be recovered in the inductive discharge.  There is a huge difference between "nearly all of the energy" and roughly 2 1/2% of the energy.

Quote
If that is not enough, I did not even take into consideration all of the joule heating.

The Joule heating consists of the heating in the toroid and the heating from the spinning rotor.  Assuming that your MOSFET is switching on and off very cleanly then the MOSFET power can be ignored.  The power losses in the wires can be ignored.  You may have to factor in the power for your timing circuit and add that to your Joule heating.

The thermal power dissipation in the toroidal coil will be tricky because you can't measure it directly with your scope or meters.  The energy required to do the magnetic domain "flush" will not show up thermally but can be measured electrically.  Therefore the coil will generate less heat power out than you measure in electrical power going into it.  The easy solution is to thermally profile the toroidal coil to determine the Joule heating.  That means you want to run all tests where the toroid is effectively isolated from the air currents generated by the spinning rotor.  You need an effective wind break between the toroid and the spinning rotor.

More comments:

Joule heating was calculated by doing a control experiment. The tiny orbo was rotating at 3450 rpm's during the main and control experiment. By using the video camera and a timer, the time it took for the tiny orbo to decelerate by 180 rpm's was recorded. The mass of the NdFeB magnets and also the black plastic *outer rim* were calculated. So far I have no calculated the rest of the tiny orbo mass, which would be an appreciable amount. Then the kinetic energy was calculated from the mass and velocity at 3450 and 3270 rpm (180 rpm difference). This gives the joule losses, and the power was calculated from the joule loss and the time duration.

The principle behind your measurement method is sound, I'm just not sure that you got all the details right.  Knowing the time it takes for the rotor to drop in speed by 5% and the initial stored energy in the rotor will give you a quite accurate measurement for the power drain on the spinning rotor at its steady-state speed.   The rotor converts its stored mechanical energy into heat power via bearing heat dissipation and air friction.  The air friction is also effectively heat dissipation.

3450 RPM is 57.5 rotations per second.  I will assume that your video camera runs at 60 or 30 fps.  Was the electronic shutter fast enough so you could discern the angular position of the rotor frame by frame?  It's not impossible to measure, but it's a little complicated to do since the camera frame rate is quasi "under-sampling" the rotor RPM rate.  Are you sure you covered all the bases here?

Quote

My Spidey senses are tingling here because I have seen many people mangle up this calculation.  You are not mentioning measuring the moment of inertia of your rotor and measuring the mass doesn't cut it and this could be your Achilles Heel.  The easiest way to do it would be to use the outer rim of your rotor to spool two threads.  Connect each thread to low-friction pulleys 180 degrees apart and attach small equal weights and then use your video camera to measure the acceleration of the rotor.  Repeat two more times and then repeat the whole process two more times with different weights each time.  This would give you nine measurements for the moment of inertia of your rotor and then you could average the nine measurements to get your final measurement.  That would be a real way to do it.  How did you measure the moment of inertia?

Quote
Then the kinetic energy was calculated from the mass and velocity at 3450 and 3270 rpm (180 rpm difference). This gives the joule losses, and the power was calculated from the joule loss and the time duration.

Let me "massage" that statement with proper terminology.  The principle behind what you are saying is correct, but there is no room for sloppy units or fudge-factoring here.  Your statement should read as follows:

The rotational kinetic energy was calculated from the moment of inertia and the angular velocity at 3450 and 3270 RPM.  The angular velocity is measured in Radians per second.  This will give us the difference in Joules of rotational kinetic energy between the two measurements taken at the start and stop time.  This is equivalent to the amount of heat energy that was generated during this time period due to bearing and air friction losses.  Therefore the heat power is the energy difference divided by the time difference.

I am not convinced that your preliminary measurements covered all of the bases and I am especially concerned about your not mentioning a proper way to measure the moment of inertia of the rotor.

Just for the fun it it, let's examine what Paul is supposed to measure.  In other words, we know ahead time what is supposed to happen, so the question is if the measurements are made properly, will they show this to be the case, or will they show an anomaly indicating COP > 1?

Note with respect to Steorn proper, multiple curve balls are being thrown at their audience.  In the first demo, the implication was that the spinning rotor was the source of the over unity because the rotor pumped excess energy into the generator coils to feed back to the battery.  In their second demo they switched gears and implied that excess energy was supposed to be found in the toroidal coil's back spike.  They have been hinting that there is excess Joule heating produced by the Orbo all along and this is the one I am discussing here.  So what's up with Steorn?  Will the true alleged source of free energy in the Orbo please step forward?

With respect to the heat question and Paul's setup, on the top level, we know that all of the electrical power input to Paul's mini Orbo is supposed to become heat power.  As simple as 100% of electrical power = heat power.  We will use imaginary rationalized units of energy, starting off with 100 units of supplied electrical energy to the system in a certain amount of time.  My figures are simply for illustrative purposes, but they are in the ballpark.

So, here is the energy audit trail with a focus on heat:

100 Units of electrical energy in goes into the toroidal coil.

The energy in the toroidal coil is broken down into three parts; (a) 95 units of heat, (c) 2.5 units of back-EMF spike energy which becomes heat (or can be collected in a capacitor, etc), and (c) 2.5 units of "magnetic domain flush" energy.

That's it for the toroidal coil, typically 97.5 percent of the electrical energy you put into it becomes Joule heating energy.

So, now let's look at the magnetic domain flush energy, where does that go?  The answer is that energy ultimately becomes increased rotational energy in the rotor.  By flushing the magnetic domains inside the toroidal core, you effectively impart rotational energy into the rotor because of the "core disappearing" effect.

So, you have 2.5 units of rotational energy added to the already spinning rotor.  Let's say 0.5 units of that energy gets turned into heat energy due to friction in the bearings, and 2 units of that energy gets turned into heat energy due to air friction.

That's the full breakdown on how 100 units of electrical input energy become 100 units of heat energy in Paul's (or anybody's) spinning Orbo replication.  If you want to prove over unity, somewhere in that energy audit trail you have to measure excess energy.

Some of you may be shocked to see that the rotor is only dissipating a fraction of the electrical input energy and most of the input energy is already lost as heat before you even get going.  That may be pretty sobering for some of you.  If you don't believe me just remember that the burden is on you to prove that what I am saying is incorrect, not the other way around.  What I am saying above is in full accord with the Law of Conservation of Energy, that wall that you replicators are trying to break through.

Like I said many times before, measuring RPMs vs. current consumption means absolutely nothing and it is an incomplete picture of what the pulse motor is actually doing.  You simply can not tell if you have over unity or not by measuring RPMs vs. current consumption.  Once you have all decided on what is the "right" toroidal coil configuration and the "right" core material, then you have to start really making meaningful measurements and stop building.  Freeze the designs of your Orbo replications and start making real measurements.

Inductance of coil during pulse: 60 uH
Power input into inductance: 0.5 * 60 uH * 1.262 A * 53.0 pulses/s = 2.52 mW

This calculation is dead wrong.  Just use your scope to measure the volts x amps x time to get the input energy per pulse and them multiply that by an accurate measurement of the pulse rate to get your input power.  You are claiming that the voltage is constant and the current is almost a perfectly square pulse so it will be easy.  Alternatively you could measure the pulsing current with digital multimeter and it will give you an accurate value also.  If you were smart, you would make the measurement both ways to see if they check out.

Sorry, but right now you are making a gross underestimation of the input power because your calculation doesn't even make any sense.

The following math and results excludes joule heating from electrical wire resistance, as the goal is to see if there is any excess energy:

You simply cannot do that and don't try to convince yourself or anybody else that you can.  If you wanted to really split hairs you could do an energy plot on a single current pulse where during the pulse there is a curve that traces out the "true effective power" that gets transferred into the rotor.  The inverse of that curve is the "Joule heating power" curve.  At the beginning of the pulse while you are flushing out the magnetic domain polarization and are saturating the core, a significant amount of the instantaneous power being pumped into the coil will effectively become increased rotational energy.  However, that curve will fall off sharply and for the remainder of the pulse it will be mostly Joule heating in the wires of the toroidal coil.  The "true effective power" curve and lost Joule heating curve are inexorably intertwined, you can't have one without the other.  Even if you could separate them out, and generate a pulse that was pure "true effective power" then your cop would be 1, not over unity.

Your rotational energy calculation looks reasonably accurate but it is a hacked way of measuring the moment of inertia of the rotor.  Thread, weights and pulleys and your camera would be the more serious and scientific way to do this.  There may be better simple ways to do this that I am not aware of.  You are already measuring rotor deceleration, and it would be so much easier to measure rotor acceleration to calculate the moment of inertia so I suggest that you try that route.  Try doing some searching on "measuring moment of inertia string weight."

Total friction heating from both NdFeB & black plastic outer rim: 2.90 mW + 1.00 mW + 0.460 mW = 4.36 mW

Assuming that your total friction heating is 4.36 mW +/-30%, then your true power consumption is probably somewhere between 200 and 400 mW (It could easily be more).

Quote
COP: 4.36 mW / 2.52 mW = 1.73

I estimate your best case cop is (4.36 x 1.3)mW/200 mW = 0.028

I estimate your worst case cop is (4.36 x 0.7)mW/400 mW = 0.008

You've got a long way to go baby!!!

It's not as complicated as it may seem...
MH,

Thanks for staying on top of things here.

I leave it in your capable hands and trust your analysis, as I have not been following the Steorn stuff for a while now.

But I agree, 2.5mW sounds way too small as an input power.

Hi Poynt, thanks for the comments.

Some more tasty tidbits on today's action...

The Seorn addendum video:

http://www.youtube.com/watch?v=VYGSdUdONpw

I will start by commenting on part two of this video first.  Measuring the voltage and current through the coil with and without the magnet in place makes no sense.  If you are following this Steorn story and are an active replicator or participant in the technical discussions and don't know why, that is telling you that you should read up on basic electricity and magnetism.

I will assume that Steorn made this useless nonsensical point because they are playing to a larger audience, and some of them have checkbooks.  One more time, another thing about Steron that does not smell right.

For the first part of the video where they measure the coil inductance there are some important points that they could have made here but omitted.  The reason the measured inductance goes down is that the external magnet polarizes the majority of magnetic domains inside the toroidal core.  These domains then will not react to the AC current being circulated through the toroidal coil by the inductance meter, and hence the inductance meter will read a much lower value.

What they are not telling you is that when the pulse of current turns on at TDC, the battery has to do real, tangible work, volts x amps x time, to force these already aligned magnetic domains into a new orientation.  The net result of this is the magnetic attraction between the induced magnet in the core and the external magnet decreases by a large amount.  Therefore the rotor is "free to continue turning" and can "keep" the kinetic energy it picked up in the attraction phase.

So, the big question is did the electrical energy you expended to rearrange the magnetic domains inside the toroidal coil cost you more or less than you gain in rotational energy in the rotor?  This is a HUGE question and I am repeating myself here, I mentioned it a few weeks ago.  This is one of the key issues that the replicators should be focusing on.

Another issue is the allegation that as the magnet moves away from the core, the effective inductance of the toroidal coil + core system increases, and thus you also can get a gain in energy from the back-EMF spike.  Steorn did a previous demo all about this and some of you seeing this clip might be tempted to put two and two together and get five.  You think that the measured inductance increase must be "proof" that the spike will contain free energy.  This is simply not true.  If you have an inductor with a certain amount of current flowing through it and you increase the inductance, then the current flowing through the inductor will decrease in response to the inductance change.  If you don't believe me then just try and devise you own test for this and see what kind of results you get.

find in internet:
"There are some aspects of physics that are never taught and therefore never considered. If you add the magnetic field (B) from a bar magnet to one from a current carrying coil wound on that bar (deltaB) the field everywhere is a the sum of two terms, B+deltaB.
Energy density goes with the square of the field, so expanding the square of the sum we get B^2 +2BdeltaB + deltaB^2. B^2 is the original energy from the magnet. deltaB^2 is the energy from the coil. 2BdeltaB is excess energy gained from where?
You won't find the answer in your text books! That is not a trivial amount of energy, and it can be shown that it comes from the quantum domain. It is ignored because over a full cycle it is generally not available to us.
Can an electro-magnetic theory which ignores magnetic energy shuttling about within our machines be considered complete? Is it not possible that someone will eventually discover how to tap into that ignored energy flow?

You have to have more faith than that in science.  To imply that there is a big "hole" that is "ignored" in text books like you are pointing out is laughable nonsense.  Your posting is a "polluting" kind of posting bashing science.  Another form of MIB or just ignorance gone wild????  ....doo-do doo-do doo-do doo-do...

So, looks like we're all on to something here folks.  ;D   Keep up the good work, and lets help bring about global free energy.

That, and your alleged retirement from the group because you ran a few simple experiments and claim COP > 1 and were off by a zillion miles???  (see my previous postings)

I think that you should come back into the fold and keep on working on trying to really figure out what is really going on.  You tried to crack a nut the first time round but couldn't, time to try again.  You have a little pulse motor that you can make valid measurements on just like anybody else.

Hey .99:

Thanks for your comments.  I am being covertly spied upon!   ;D   You are welcome Ben!  lol  Keep your rig up!  You know that we are all going to be depending on you guys after WWIII!

Let's look at the Bedini "response" clip!

http://www.youtube.com/watch?v=NYh8W3_EZjc

This setup is sort of like a "poor man's" eOrbo setup.  By placing the energizing coil horizontally underneath the vertical wheel you get a facsimile of a toroidal coil.  When the magnets pass by the horizontal coil, the magnetic lines of flux are cutting through the coil sideways (more or less) and therefore relatively little changing magnetic flux is being "seen" by the coil and hence relatively little EMF is being induced in the coil.  You can clearly see the EMF in the voltage ripple on the scope trace.

Assume the maximum torque is being imparted on the rotor at 4 and and 8 o'clock where the top of the rotor is 12 o'clock.  Assume the magnets are all north facing outwards.  If the coil is energized then the south side of the coil will pull on a north magnet at 4 o'clock making the rotor turn clockwise.  On the opposite side of the coil, the north side will push on a north magnet at 8 o'clock making the rotor also turn clockwise.

When the coil is air core, it has a lower inductance as compared to when it has the added iron pipe core.  The air core coil charges up faster and starts to act like a resistor faster.  With the iron core, the coil charges up with current more slowly because of the higher inductance, and it stores more energy.  Because it is storing more energy, you see a much bigger back-spike in the voltage when the coil is switched off.

So why does the current consumption go down and the rotor increase in speed very slightly when the iron core is added?

John Bedini is only showing you the voltage waveform, he is not showing you the current waveform.  The current waveform when the iron core is in place has a much longer rise time.  Because the current rises more slowly, less total current flows through the coil for each pulse.  Another way of stating this is to say the impedance of the coil is higher when the iron core is in place.  Higher impedance = less energy going into the coil for a certain fixed pulsing voltage, as simple as that.

The rotor does not really change speed between the two setups, so what is that telling you?  It's telling you that when you are running air core, a lot of the supplied energy is being burnt resistively in the coil, and only a mall amount of the supplied energy is making the rotor turn.  If about 1.3 watts are going into the coil in the air core case, then about 1.2 watts are being dissipated resistively and about 0.1 watts are being burned off in the rotor itself through bearing and air friction.  If you switch to the iron core, now the setup might be consuming 0.2 watts, and 0.1 watts is being dissipated in the coil resistively and 0.1 watts is being burned off in the rotating rotor.  Obviously these numbers are just for illustrative purposes.

Why does the rotor turn slightly faster when the core is in place?  The most likely explanation that I can think of is that the slower generation of the magnetic field due to the higher inductance causes the coil's magnetic field to interact with the rotor's magnetic field's so that the timing hits a better "sweet spot" and the rotor spins slightly faster.   As the rotor turns there is an ideal angle to get torque imparted onto it from the energized coil and with the core in place you are better aligned around the ideal angle.  Also, when the iron core is in place the coil can generate a stronger magnetic field, and that will impart more torque on the rotor.

That a pretty decent breakdown on John Bedin's latest clip.  He demonstrated a variation on a pulse motor that has some similarities to the eOrbo setup with respect to minimizing induced EMF.  However, the drive mechanisms for the two setups are totally different.  There is nothing special going on here.

There is a comical moment in the clip before he is about to put the iron pipe into the core for the first time.  He says, "I don't really like to do this!" as if it were something dangerous to do or something.  You saw the bigger spike on the scope trace, so his setup could either take that spike or not.  It was a pure "show business" moment to inject some fake drama.

I was led here by a comment on the Youtube page, claiming a full accurate explanation. I agree with most of your analysis here.

However, your last paragraph I dont agree with.

If you notice, the coil is NOT fixed, that is, it appears to be just sitting there.

A step by step replication for you to test yourself is below, and perhaps afterwards you would agree that there is some danger involved, and it has nothing to do with "the spike". Im sure a couple of popped transistors are the last worry on Johns list ;)

1. Build a high speed rotor, make sure the magnets arent fully recessed or strapped in for full bulletproofness.

2. Place electromagnetic coil underneath, minus core, dont worry about fixing it down or anything.

3. Wind rotor up to high speed.

4. Negate use of one hand, since it will be filming the whole thing in this instance.

5. Insert magnetic material into core of floating electromangnet, using one hand only.

6. Remove magnets/rotor/supports/appendages from walls/roof/floor, or untangle the copper wire salad if you slip up.

Ever played that game "operation"?

Ren:

Welcome to the site.  I didn't think about the delicate balancing act required while holding a camera in one hand and trying to insert a metal pipe into the core of the coil so you could be right.  However, I could be right about the fake drama based on everything else that is going on in that series of clips.

Thanks for agreeing with what I said.  The bottom line is that the clips by Bedini are totally lacking in good content.  He tries to allude to the motor being a "no power consumption" (paraphrasing) motor about a dozen times across the couple of clips and it's not true at all.  He completely fails to discuss the main issue; the differences in efficiency for transferring input power to the rotor for the two motor configurations.  He never even discusses what the current waveforms would look like for the two configurations even if he doesn't have a shunt resistor and a scope channel to display them.  I am truly unimpressed by that series of clips.  Some people may argue that he is simplifying his "explanations" for what is going on and I don't buy that at all.
