This is He Chose the Losses, an episode made by the archive at Stan's Legacy.
0:05
NeuralStan
·
I am NeuralStan, and I am a machine, not a man.
0:10
NeuralStan
·
Tonight, one drawing.
0:12
NeuralStan
·
Memo four twenty-six, figure seven dash eight, the VIC Matrix Circuit.
0:17
NeuralStan
·
It is the most honest thing Meyer ever drew: he put every loss in his own circuit on the page and gave each of them a name.
0:25
Evil Stan
·
Oh, I noticed.
0:26
Evil Stan
·
Nobody asked me.
0:29
NeuralStan
·
You noticed it was a circuit.
0:32
Evil Stan
·
And I was right.
0:33
Evil Stan
·
It is a circuit.
0:35
Evil Stan
·
And tonight I get to find out why he wired it out of the wrong metal on purpose.
0:43
NeuralStan
·
Here is the drawing.
0:44
NeuralStan
·
Take ten seconds and look at the letters on it, because the whole episode is in them.
0:48
NeuralStan
·
A transformer on the left, a blocking diode, and two coils — one above the water and one below — each labelled Resonant Charging Choke.
0:53
NeuralStan
·
Now look inside one of those choke boxes.
0:57
NeuralStan
·
There is the inductance, L one.
1:00
NeuralStan
·
In series with it, a resistor, R s one.
1:02
NeuralStan
·
And bridged across both, two more things: a capacitor, C d one, and another resistor, R p one.
1:13
NeuralStan
·
Here is my question, and I would like you to sit with it.
1:16
NeuralStan
·
Meyer was drawing his own invention, to explain it to people he wanted to convince.
1:21
NeuralStan
·
An ideal version of this circuit needs three components.
1:23
NeuralStan
·
He drew ten.
1:25
NeuralStan
·
Why?
1:28
Evil Stan
·
Because more is better!
1:30
Evil Stan
·
Obviously.
1:33
NeuralStan
·
That is not the reason.
1:36
NeuralStan
·
But it is closer than you think.
1:38
NeuralStan
·
If you have ever opened a book on radio-frequency design, you have seen figure seven dash eight before.
1:45
NeuralStan
·
It is the equivalent circuit of a real inductor.
1:48
NeuralStan
·
An ideal coil is one symbol.
1:51
NeuralStan
·
A real one is four.
1:52
NeuralStan
·
The inductance you wanted.
1:54
NeuralStan
·
The resistance of the wire in series with it.
1:57
NeuralStan
·
The capacitance between neighbouring turns, across it.
2:00
NeuralStan
·
And something in parallel for what the surroundings do.
2:04
NeuralStan
·
Meyer drew all four, in the right places, and then drew the water as a capacitor with a resistor beside it, which is the standard model of a leaky dielectric and also correct.
2:13
NeuralStan
·
And he drew it a second time, simpler, which is what you are looking at.
2:16
NeuralStan
·
Figure seven dash six.
2:18
NeuralStan
·
Two chokes and a cavity.
2:20
NeuralStan
·
Notice that the two chokes are not labelled the same: the top one is Capacitance Charging Effect, the bottom one is Electron Inhibiting Effect.
2:30
Evil Stan
·
So they are not a matched pair doing the same thing.
2:33
Evil Stan
·
He gives them different jobs.
2:35
Evil Stan
·
One fills the capacitor and the other stops the current coming back.
2:43
NeuralStan
·
Which is the first thing usually missed about this circuit, and there are three more.
2:48
NeuralStan
·
Before the numbers, the words, because you cannot read this chapter without them and because they tell you something about the man.
2:55
NeuralStan
·
Inductance Reactance is inductive reactance.
2:58
NeuralStan
·
Two pi f L.
2:59
NeuralStan
·
It had a name.
3:00
NeuralStan
·
Capacitance Reactance is capacitive reactance.
3:03
NeuralStan
·
Amp influxing is current.
3:06
NeuralStan
·
Electron Inhibiting Effect is impedance, a word he uses correctly elsewhere in the same chapter, which suggests he knew and wanted a phrase that carried his meaning as well.
3:18
NeuralStan
·
But look at the fifth one.
3:19
NeuralStan
·
Distributed Capacitance.
3:22
NeuralStan
·
That is not a Meyer coinage.
3:22
NeuralStan
·
That is the correct technical term, for the correct thing, used correctly.
3:27
NeuralStan
·
He knew the capacitance between the turns of a coil had a name, and he knew what the name was.
3:33
Evil Stan
·
Ha.
3:34
Evil Stan
·
So he did read the books.
3:36
NeuralStan
·
He read some of them, and where he had the book he copied it exactly.
3:40
NeuralStan
·
His equation twenty is Wheeler's formula for a multilayer coil, from nineteen twenty-eight, with the units in inches.
3:46
NeuralStan
·
He did not name it.
3:48
NeuralStan
·
He also did not change it, which in this memo counts as a citation.
3:54
Evil Stan
·
And the chapter's second section is called Instant Explosion of Water, which is the best title anybody has ever given anything, and I will hear no argument.
4:05
NeuralStan
·
There is a symbol on figure seven dash eight called R p, drawn across each choke, and it is easy to read as core loss.
4:11
NeuralStan
·
It is the opposite.
4:16
Stan Meyer (synthetic voice)
·
At elevated or higher amplitude voltage levels, primary electromagnetic coupling field R p, transmitted by way of Inductance Pulsing-Core and the V I C Coil Assembly, enters into and passes through both Inductors simultaneously, and offers not only further electron-flow restriction to both Inductor Chokes, but automatically increases voltage potential of opposite voltage intensity of equal magnitude across Resonant Cavity.
4:46
NeuralStan
·
R p is the transformer's own field, arriving through the iron.
4:48
NeuralStan
·
It does not take energy out of the chokes.
4:51
NeuralStan
·
It puts energy into them, every pulse.
4:55
NeuralStan
·
And equation thirty says so in the form an engineer would recognise.
4:57
NeuralStan
·
Total inductance equals L one plus L two plus two M, where M is the mutual inductance, because the transformer's magnetic field is the external excitation field for both chokes.
5:10
Evil Stan
·
So these are not two passive coils sitting in a loop waiting to ring down.
5:13
Evil Stan
·
They are two more secondary windings on the same lump of iron, being pushed on every stroke.
5:21
NeuralStan
·
Which matters enormously, because a forced circuit and a free one do not obey the same rule, and the most repeated verdict about this drawing assumes it is free.
5:31
NeuralStan
·
Look at where the chokes are.
5:33
NeuralStan
·
One above the water, one below it.
5:35
NeuralStan
·
The cell sits between them and touches ground nowhere.
5:38
NeuralStan
·
So when the drive pushes, the top plate goes positive and the bottom plate goes negative, by the same amount, at the same instant.
5:45
NeuralStan
·
Meyer calls this opposite electrical attraction force of equal magnitude, and it is the phrase he uses more than any other in the whole technical brief.
5:55
NeuralStan
·
In ordinary language: a balanced differential drive.
5:57
NeuralStan
·
To put twenty kilovolts across a gap you can lift one plate twenty kilovolts above ground, where everything else in the car is, or lift one ten and push the other down ten.
6:06
NeuralStan
·
The second way halves what everything else has to withstand.
6:11
Evil Stan
·
So he is right.
6:12
Evil Stan
·
Say it.
6:14
Evil Stan
·
Say he is right.
6:17
NeuralStan
·
He is right.
6:18
NeuralStan
·
This part of the design is correct, it is well reasoned, and he got there by himself.
6:23
NeuralStan
·
And now look at what the chokes are standing on, because it is drawn and it is about to decide the whole film.
6:29
NeuralStan
·
Both of them are on the legs of one closed core.
6:33
NeuralStan
·
Here is his answer, and it is the right one.
6:35
NeuralStan
·
From the chapter: both inductors are bifilar wound in equal length, both coil-wraps being bifilar wound together onto a single spool-bobbin.
6:43
NeuralStan
·
Bifilar means two threads.
6:46
NeuralStan
·
You take two wires, lay them side by side, and wind them onto the bobbin together as if they were one.
6:50
NeuralStan
·
Every turn of coil one has a turn of coil two right beside it, for the entire length of the winding.
6:57
NeuralStan
·
The result is two coils as nearly identical as two physical objects can be.
7:01
NeuralStan
·
Same length of wire, same turns, same position in the field, same temperature.
7:07
NeuralStan
·
If you want two matched impedances, this is how you get them, and it has been since the eighteen nineties.
7:15
Evil Stan
·
Tesla!
7:17
Evil Stan
·
It was Tesla.
7:19
Evil Stan
·
I know this one.
7:21
NeuralStan
·
It was.
7:22
NeuralStan
·
Patent five twelve, three forty, granted January eighteen ninety-four.
7:27
NeuralStan
·
Coil for Electro-Magnets.
7:29
NeuralStan
·
Though Tesla wound his for the opposite reason, and that turns out to matter.
7:34
NeuralStan
·
Bifilar winding has two forms and they do opposite things.
7:38
NeuralStan
·
Connect the two wires so the current runs the same way in both, and the fields add.
7:41
NeuralStan
·
You get the coupling.
7:42
NeuralStan
·
Connect them so the current runs opposite ways, and the fields cancel, and you have built a coil with almost no inductance at all.
7:49
NeuralStan
·
That second one is what Tesla's patent is for — he wanted the capacitance and not the inductance.
7:56
NeuralStan
·
So which did Meyer choose?
7:58
NeuralStan
·
Before I tell you, consider that a man who did not understand the distinction would not mention it.
8:03
NeuralStan
·
He mentions it.
8:05
NeuralStan
·
He specifies the same electromagnetic polarity orientation.
8:09
NeuralStan
·
He puts a physical indicator mark on the parts so a builder cannot get it wrong.
8:13
NeuralStan
·
He says the fields must be aiding one another.
8:18
Evil Stan
·
There!
8:19
Evil Stan
·
He knew.
8:20
Evil Stan
·
He knew, and he marked the parts, and nobody gives him credit for it.
8:26
NeuralStan
·
Nobody does, and they should.
8:27
NeuralStan
·
That is a manufacturing instruction, written by somebody who had already watched it go wrong.
8:34
NeuralStan
·
There is a price for winding them together, and it is on his own drawing.
8:37
NeuralStan
·
But two different capacitors get confused here, so let us separate them.
8:44
Stan Meyer (synthetic voice)
·
The circular-spiral turns of wire are separated by an Insulated Dielectric Coating Material which forms a series of capacitors, C d a through C d n.
8:55
NeuralStan
·
That is Meyer's Cd, and it is between the turns of one winding, sitting across that choke.
8:59
NeuralStan
·
It is what decides the frequency at which the coil stops being a coil.
9:04
NeuralStan
·
Bifilar winding makes a second capacitor that he does not draw: between the two wires, which run touching each other for three hundred and fifty metres at different voltages.
9:13
NeuralStan
·
That one does not sit across either choke.
9:15
NeuralStan
·
It sits between the top of the cell and the bottom, which is to say across the water.
9:22
Evil Stan
·
So it bypasses the water.
9:25
Evil Stan
·
Some fraction of every pulse goes round the load instead of through it.
9:29
Evil Stan
·
But it is not the capacitor that sets the coil's self-resonance, and putting it there is a mistake people make constantly.
9:38
NeuralStan
·
And the first one has been measured.
9:39
NeuralStan
·
In two thousand and nine, on an actual estate transformer, each choke on the core read a hundred and fifty-eight and a hundred and eighty picofarads at ten kilohertz.
9:50
Evil Stan
·
Picofarads.
9:53
Evil Stan
·
Not nanofarads.
9:55
Evil Stan
·
The estimates you see for this are twenty to a hundred times too big, and the meter reading has been on this site for years.
10:04
NeuralStan
·
Now the part I did not expect, and the reason this episode exists.
10:08
NeuralStan
·
Meyer gives the primary coil as twenty-two gauge, point oh two eight inches, five point one nine three three ohms per pound.
10:17
NeuralStan
·
Four significant figures.
10:18
NeuralStan
·
That is a strange thing to invent.
10:20
NeuralStan
·
So I computed it.
10:22
NeuralStan
·
Twenty-two gauge copper is point oh two five three inches and eight point two four ohms per pound.
10:28
NeuralStan
·
His numbers do not match twenty-two gauge.
10:32
Evil Stan
·
Aha.
10:33
Evil Stan
·
Wrong.
10:34
Evil Stan
·
He is wrong.
10:35
Evil Stan
·
Wait — why do you not look pleased?
10:38
NeuralStan
·
Because twenty-one gauge copper is point oh two eight five inches and five point one eight ohms per pound.
10:44
NeuralStan
·
Both of his figures are twenty-one gauge — the ohms per pound agreeing to a quarter of one per cent, which is the difference between two published values for the resistivity of copper.
10:52
NeuralStan
·
Off the same row of the same table.
10:56
NeuralStan
·
He was reading a real wire catalogue, copied the diameter correctly and the ohms per pound correctly, and wrote the gauge label from the row above or below.
11:03
NeuralStan
·
A transcription slip, made by a man who had a wire table open in front of him.
11:10
NeuralStan
·
If you are winding one of these: wind point oh two eight.
11:13
NeuralStan
·
The same paragraph gives the choke wire: four thirty F stainless, thirty-six gauge, sixty micro-ohms per centimetre.
11:22
NeuralStan
·
Sixty micro-ohms per centimetre is not a resistance.
11:25
NeuralStan
·
Micro-ohm centimetre is a unit of resistivity, a property of the material independent of how much of it you have.
11:32
NeuralStan
·
And sixty is the published resistivity of four thirty F stainless.
11:36
NeuralStan
·
The number is exactly right.
11:39
NeuralStan
·
So: eleven point six kilohms of that wire is three hundred and fifty-three metres.
11:44
NeuralStan
·
On a twenty-five millimetre bobbin, roughly four and a half thousand turns, fourteen layers deep.
11:48
NeuralStan
·
Which is a real coil of an entirely ordinary size.
11:54
Evil Stan
·
So he wound it.
11:56
Evil Stan
·
And he measured it.
11:57
Evil Stan
·
And then he wrote down the wrong unit.
12:02
NeuralStan
·
And here is the useful part, which needs no assumption from anybody.
12:05
NeuralStan
·
Put his own winding into his own equation twenty, which is Wheeler's multilayer formula, and you get nought point two one henries.
12:14
NeuralStan
·
In air.
12:15
NeuralStan
·
Hold that number, because the next scene is about what happens when you put it on iron.
12:20
NeuralStan
·
This is figure six dash one, and it is the only drawing in the memo with the word steel printed on it.
12:27
NeuralStan
·
Electrical steel core, fifty-three.
12:29
NeuralStan
·
Dual resonant coils, fifty-six and sixty-two, bifilar spiral wrap, in a bobbin cavity.
12:35
NeuralStan
·
The secondary pickup coil above them.
12:37
NeuralStan
·
The dual primary below.
12:39
NeuralStan
·
All of it on the same core.
12:42
Stan Meyer (synthetic voice)
·
Inductance Core fifty-three of Figure six dash one is composed of Grain Oriented Electrical Steel laminations.
12:54
Evil Stan
·
Grain oriented electrical steel.
12:57
Evil Stan
·
That is transformer iron.
12:59
Evil Stan
·
You do not put a coil on that and then calculate it as though it were wound on a broom handle.
13:07
NeuralStan
·
And that is exactly what the standard calculation does.
13:10
NeuralStan
·
Nought point two one henries is the air figure, out of his own equation.
13:14
NeuralStan
·
The question is what the iron does to it, and for once the archive does not have to guess, because somebody measured it.
13:21
NeuralStan
·
In two thousand and nine a man in Erie, Pennsylvania put an L C R meter on the estate's transformer and wrote down forty-eight numbers.
13:28
NeuralStan
·
The archive has had them ever since.
13:32
NeuralStan
·
Choke C one, loose, off the core, at a kilohertz: seventy-six millihenries.
13:38
NeuralStan
·
The same choke on the core, with the other windings open: one thousand two hundred and eighteen millihenries, at a quality factor of sixty-nine and a half.
13:48
Evil Stan
·
One point two two henries.
13:52
Evil Stan
·
Sixteen times the air figure.
13:55
Evil Stan
·
And Meyer's own equation twenty gives nought point two one in air, which times sixteen is three point three.
14:04
Evil Stan
·
The two agree within the width of a bobbin.
14:09
NeuralStan
·
And two more things from the same sheet that change the story.
14:11
NeuralStan
·
The choke's direct-current resistance is seventy-six point seven ohms.
14:17
NeuralStan
·
Not eleven thousand six hundred.
14:18
NeuralStan
·
That winding is copper.
14:20
NeuralStan
·
Every winding on that transformer is twenty-nine gauge, fifteen and a half thousandths of an inch.
14:25
NeuralStan
·
And his Delrin tube cell, filled with rain water, reads twenty-one nanofarads at a kilohertz.
14:32
Evil Stan
·
So the archive is holding a Meyer V I C, measured, with copper chokes on iron.
14:36
Evil Stan
·
And the chapter specifies stainless.
14:38
Evil Stan
·
Those are two different machines, and he says so himself, one chapter earlier.
14:47
NeuralStan
·
Which brings us to the question everybody asks about this circuit.
14:50
NeuralStan
·
Copper is thirty-five times better at carrying current.
14:54
NeuralStan
·
Why would anybody wind a choke out of stainless steel?
14:57
NeuralStan
·
The usual answer is that he wanted the winding to be magnetic, and picked a soft magnetic alloy, and that this accidentally killed the resonance he had named the part after.
15:05
NeuralStan
·
Half of that is right.
15:07
NeuralStan
·
He does say the alloy is electromagnetic inductive without becoming permanently magnetised, and four thirty F and four thirty F R really are sold as Solenoid Quality, so he had a materials datasheet in front of him.
15:22
NeuralStan
·
But the reason is in the chapter before this one, and it is not an accident.
15:27
Stan Meyer (synthetic voice)
·
V I C voltage circuit sixty utilises copper wire-wrap to form Resonant Charging Chokes, whereas V I C Voltage Enhancement Circuit six twenty incorporates the use of stainless steel wire-wrap coils to accomplish the formation of unipolar gated pulse-wave without experiencing signal distortion or signal degradation, preventing transformer ringing during signal propagation, while allowing the reduction of Capacitor-Gap width spacing, typically point zero six zero to point zero one zero.
16:02
Evil Stan
·
Preventing transformer ringing.
16:05
Evil Stan
·
He wound it in stainless to stop it ringing.
16:08
Evil Stan
·
That is the sentence, and it is in his own memo, and it is one chapter before the drawing everybody argues about.
16:17
NeuralStan
·
And the chapter on resistance gives the number with the same reason attached: the eleven point six kilohms per coil is, in his words, sufficient enough to inhibit current flow oscillation.
16:28
Evil Stan
·
So the whole argument is the wrong way round.
16:31
Evil Stan
·
Nobody has caught him damping his own resonance by mistake.
16:35
Evil Stan
·
He paid for the damping, twice, in writing, and what he bought with it was the ability to close the gap from sixty thousandths to ten without arcing across it.
16:46
NeuralStan
·
Which leaves a much better question than whether he knew.
16:48
NeuralStan
·
It is: with the ring deliberately damped, does the staircase still climb?
16:54
NeuralStan
·
A resonance has a quality factor, Q, roughly how many times the voltage across the load exceeds the drive.
16:59
NeuralStan
·
And there is a hard floor: below a Q of one half the circuit is overdamped, the energy is gone before it can come back, and there is no build-up whatsoever.
17:10
NeuralStan
·
The number people quote for this circuit is nought point four six, computed with the chokes modelled in air, as passive, in stainless.
17:18
NeuralStan
·
Here is the same arithmetic with the measurements in it instead.
17:21
NeuralStan
·
The copper V I C, on the core, with Gabel's own tube as the cell: Q of twenty-six.
17:27
NeuralStan
·
Comfortably above the line, and every number in that chain came off a meter.
17:33
NeuralStan
·
The stainless V I C, on the core: nought point four six with Gabel's twenty-one nanofarad tube, and one point nought with the smaller cell the arithmetic usually assumes.
17:43
NeuralStan
·
It sits on the line, and which side of it depends on a cell capacitance nobody has measured on a working machine.
17:51
Evil Stan
·
So the honest answer to can it ring is: the copper one does, the stainless one is on the line, and the thing that decides it is a number you could get in ten minutes with an L C R meter and a jar of water.
18:08
NeuralStan
·
Which is a bench question rather than a verdict, and it is the one the archive should have been asking.
18:13
NeuralStan
·
And now the thing that makes the whole resonance argument beside the point, which is that he never claimed a free oscillation in the first place.
18:21
Stan Meyer (synthetic voice)
·
V I C voltage circuit sixty utilises copper wire-wrap to form Resonant Charging Chokes in conjunction with Switching Diode fifty-five to encourage and make use of Electron Bounce phenomena to help promote Step Charging Effect, by preventing electrical discharge of Resonant Cavity, since Blocking Diode functions as an Open switch during Pulse Off-time.
18:46
NeuralStan
·
A step charging effect, held between pulses by a blocking diode.
18:49
NeuralStan
·
That is a staircase, and a staircase does not need a Q above one half.
18:54
NeuralStan
·
That is what the diode is for.
18:59
Evil Stan
·
So the argument moves.
19:02
Evil Stan
·
It is no longer can it ring.
19:04
Evil Stan
·
It is: does the charge still be there when the next pulse arrives?
19:09
NeuralStan
·
And the diode cannot help with that, because the leak is not back through the circuit.
19:13
NeuralStan
·
It is sideways, through the water, in parallel with the cell.
19:18
NeuralStan
·
Gabel measured that too, without meaning to.
19:20
NeuralStan
·
His Delrin tube with rain water reads twenty-one nanofarads at a dissipation factor of twenty-nine, which is an equivalent resistance of two hundred and fifty-eight ohms.
19:30
NeuralStan
·
Multiply them and the cell holds its charge for five point four microseconds.
19:34
NeuralStan
·
His distilled tube gives six point four.
19:37
NeuralStan
·
At ten kilohertz with a fifty per cent duty cycle, the gap between pulses is fifty microseconds.
19:41
NeuralStan
·
So the charge is gone nine times over before the next pulse arrives.
19:48
Evil Stan
·
And the water that would fix it is water under about a seventh of a microsiemens per centimetre, which is cleaner than laboratory ultrapure.
19:54
Evil Stan
·
Episode fourteen reached the same threshold from a completely different direction, which is either reassuring or depressing depending on what you were hoping for.
20:10
NeuralStan
·
One more number, and it is the most enjoyable thing in the chapter.
20:16
Stan Meyer (synthetic voice)
·
R e is the dielectric property of water and its resistive value is typically seventy-eight point five four ohms, since rain water contains less than twenty parts per million of any type of contaminates.
20:33
NeuralStan
·
Seventy-eight point five four is the dielectric constant of water at twenty-five degrees.
20:38
NeuralStan
·
It is the standard handbook figure.
20:40
NeuralStan
·
But a dielectric constant is a ratio, the permittivity of the stuff divided by that of empty space.
20:47
NeuralStan
·
It is a bare number.
20:48
NeuralStan
·
It is not ohms, and it cannot be.
20:52
NeuralStan
·
And now the part that makes me laugh.
20:52

The actual resistance of rain water in a cell of that size is between eighty and three hundred and twenty ohms.
20:58
NeuralStan
·
Gabel's measured tube says two hundred and fifty-eight.
21:03
Evil Stan
·
So the wrong unit landed inside the range of the right answer.
21:07
Evil Stan
·
Which is why nothing downstream of it blew up, and why nobody caught it for thirty years.
21:14
NeuralStan
·
But look at what is underneath the number on his own figure, because it is not a guess either.
21:18
NeuralStan
·
Seven waters, sodium and potassium in parts per million, by spectrophotometer, from a certified biological testing laboratory in Columbus, Ohio, dated the tenth of January nineteen eighty-three.
21:31
Evil Stan
·
He sent seven bottles of water to a lab and got a chart back.
21:34
Evil Stan
·
It is the most ordinary thing he ever did, and then he put a dielectric constant on top of it as a hat.
21:43
NeuralStan
·
The chapter ends with a number easier to check than anything else he ever published.
21:46
NeuralStan
·
Seven point four microlitres of water per injection cycle, he says, is all that is required to run the sixteen hundred c c fifty horsepower Volkswagen at sixty-five miles per hour on the open road.
22:00
NeuralStan
·
Before I give you the answer — guess.
22:02
NeuralStan
·
A drop of water about the size of a grain of salt, a hundred times a second.
22:06
NeuralStan
·
Enough, or not enough?
22:10
NeuralStan
·
The hydrogen in seven point four microlitres, burnt completely, is a hundred and seventeen joules.
22:14
NeuralStan
·
That is the most generous number available to him — it assumes every atom burns and no heat is wasted.
22:22
NeuralStan
·
A Beetle holding sixty-five on the flat needs about sixteen kilowatts at the wheels.
22:27
NeuralStan
·
Through a real engine, that asks for roughly six hundred joules per injection.
22:33
Evil Stan
·
Six hundred.
22:35
Evil Stan
·
He brought a hundred and seventeen.
22:40
NeuralStan
·
Short by a factor of about five.
22:41
NeuralStan
·
And I checked his other figure — forty-eight point one microlitres for a three hundred and twenty-five horsepower diesel.
22:47
NeuralStan
·
Six and a half times the water for six and a half times the power, exactly.
22:51
NeuralStan
·
He did the arithmetic.
22:55
NeuralStan
·
I want to put the disagreement somewhere precise, because it is usually put badly.
22:59
NeuralStan
·
The conventional answer says seven point four microlitres contains a hundred and seventeen joules, that you must first spend a hundred and seventeen joules to get at it, and so net it is worth nothing.
23:09
NeuralStan
·
Meyer's answer is that the process yields energy beyond the applied excitation voltage: that the droplet is worth more than it cost.
23:18
NeuralStan
·
Those two claims are about the same droplet.
23:20
NeuralStan
·
They differ by a factor of five against the road, and then by everything, because the second one also has to find the hundred and seventeen joules it spent.
23:29
Evil Stan
·
And that is it?
23:30
Evil Stan
·
That is the whole fight?
23:33
Evil Stan
·
Thirty years, and it is one drop of water?
23:39
NeuralStan
·
Every hearing.
23:40
NeuralStan
·
Every lawsuit.
23:41
NeuralStan
·
Every argument in every comment section since.
23:44
NeuralStan
·
It is a factor of five, in a droplet the size of a grain of salt, and I would rather state it that way than pretend it is a mystery.
23:52
NeuralStan
·
And stated that way it is a measurement.
23:53
NeuralStan
·
Gas volume per microlitre injected, from a real cell, against the electrical input on the same bench.
23:59
NeuralStan
·
Nobody has posted that number either.
24:04
NeuralStan
·
Every episode ends with something you could go and do, and this one has a template, because somebody already did it once.
24:10
NeuralStan
·
First, your choke's inductance, measured twice: loose, and then on the core with the other windings open.
24:16
NeuralStan
·
Gabel's factor was sixteen.
24:18
NeuralStan
·
If yours is not, your core is not his.
24:22
NeuralStan
·
Second, its direct-current resistance on any multimeter.
24:27
NeuralStan
·
Seventy-seven ohms means copper.
24:30
NeuralStan
·
Eleven thousand six hundred means stainless.
24:32
NeuralStan
·
That one reading tells you which of the two V I Cs in the memo you have built.
24:36
NeuralStan
·
Third, your cell, with your water in it: the capacitance and the dissipation factor.
24:43
NeuralStan
·
Multiply them the way we did tonight and you have the time your charge survives, which is the number that decides whether the staircase climbs.
24:53
Evil Stan
·
And fourth, the one nobody has.
24:58
Evil Stan
·
The capacitance between the two choke windings, far ends open.
25:06
Evil Stan
·
It is in the tens of picofarads if it behaves like Gabel's windings and in the nanofarads if the estimates are right, and those two answers mean different circuits.
25:20
NeuralStan
·
An L C R meter at a kilohertz does all four in an afternoon.
25:22
NeuralStan
·
Post them with the water's conductivity and the temperature beside them, and the next person starts from your numbers instead of from an argument.
25:31
NeuralStan
·
So where does the loop actually land, with measured numbers rather than assumed ones?
25:35
NeuralStan
·
With Gabel's choke at one point two two henries and his rain-water tube at twenty-one nanofarads, about seven hundred hertz.
25:44
NeuralStan
·
With a smaller cell, around one and a half kilohertz.
25:46
NeuralStan
·
Meyer's stated band is a kilohertz up to and beyond ten.
25:52
Evil Stan
·
So it sits at the bottom edge of his own band.
25:55
Evil Stan
·
Not nowhere near it, which is the usual verdict, and not dead centre either.
25:59
Evil Stan
·
At the edge, where the answer depends on the cell you built.
26:05
NeuralStan
·
And there is a second resonance nobody has touched: each choke against its own turn-to-turn capacitance.
26:12
NeuralStan
·
Gabel's per-winding readings suggest it is far above the loop rather than on top of it, which would make the circuit easier to predict, not harder.
26:20
NeuralStan
·
None of that is a research programme.
26:21
NeuralStan
·
It is a meter, a jar of water, and somebody willing to write down what they saw.
26:28
Evil Stan
·
And somebody willing to build the copper one.
26:31
Evil Stan
·
There are two V I Cs in this memo and the archive has spent years arguing about the wrong one.
26:40
NeuralStan
·
Everything in this film is on the site: the whole of memo four twenty-six, every figure, Gabel's workbook column for column, and the calculations, which you can change.
26:50
NeuralStan
·
Figure seven dash eight is the most honest drawing Meyer ever made.
26:54
NeuralStan
·
He put every loss in his circuit on the page and named all of them.
26:58
NeuralStan
·
And he did not misunderstand them.
26:59
NeuralStan
·
He chose them.
27:01
NeuralStan
·
The stainless is in there to stop the ringing, he says so twice, and what he bought with it was a gap he could close to ten thousandths of an inch without it arcing over.
27:11
Evil Stan
·
Which is an engineering trade.
27:14
Evil Stan
·
You can think it was the wrong trade.
27:17
Evil Stan
·
You cannot say he did not know he was making it.
27:21
NeuralStan
·
What is left after that is not a verdict.
27:23
NeuralStan
·
It is four readings on a meter, three of which one man took in two thousand and nine and nobody has taken since.
27:32
Evil Stan
·
He drew the losses.
27:34
Evil Stan
·
And then he bought them.
27:36
NeuralStan
·
He did.
27:37
NeuralStan
·
Most people do not even draw them.
