The first Toroidal Power Unit  [ TPU ]

by Steven Mark

[Here's a transcript of this first video.  If anybody has a better video then what's available on the internet please let us know. -EMdevices]


most devices are capable of generating electricity... and ...they're conversion devices, they?re not free energy devices ...they're ... they're not ?devices that can't be properly demonstrated.

these devices... take energy from the natural magnetic field of the earth, which has an inherent frequency... we basically tune into that...and ?take the energy that is readily available ....from the earth's magnetic field ? and produce electricity from it..

[takes out a voltage meter]

this is a voltage meter..  I'll use this voltmeter to demonstrate the power output of one of my devices....

[takes small TPU from box and places it on top of the table equipment]

this is the smallest device ....that I ever made.. one of the first devices ... this is put together with bailing wire... it is very very small...you can tell by the size of my hand and fingers that this device is very small... it doesn't contain any batteries capable of generating the amount of electricity that you're going to be witnessing here..

now I'm going to turn the device on ?through the use of this single measure... these wires travel directly to this meter right here......

[mumbling to himself while hooking up wires]....

ok...[clicks buttons on meter].....[starts lifting small magnet]...ok ... now ?I'm going to take this magnet  ? place this magnet right here

[places magnet on small toroid]

..the device is now putting out a constant ... consistent ?.62 volts ... 61.8 ? it will fluctuate back and forth ?.voltage wise ...

[removes magnet]

if you remove the magnet ?from the system ... the voltage automatically goes ...starts going down? there is a frequency pattern set up in here  ...and it takes a while to wind down similar to a jet turbine

[puts the magnet back on the toroid]

take the magnet ...put the magnet back within the device and immediately the voltage goes back up again ?61.6 ? 61.8

[lifts device in hands]

if you take this device ?and hold it in your hands.. it prod...it it vibrates ever so slightly right around 7.3 cycles per second ...and ...generates a little bit of heat ...during this conversion process...

[He turns device upside down]

if you take this device ?and for some unknown reason ...turn it upside down... immediately it stops producing electricity ?down now to 13 volts 12 volts ?it stops producing electricity

[He flips device back in normal position]

 ?.reverse it again ?.and immediately ? back up to 61.6 volts ...  I have no explanation for why that is

this is the smallest device that I have come up with so far... this device will produce 61.5 volts ...literally forever...the amount of current that it produces very.. varies ... at the present time it's 61.5 volts it puts out about ...25 watts ....the more current you draw from the device the more heat it generates....

now I'm going to show you a larger device I have ? also of similar construction...
very very cheaply put together ?there?s no mass circuitry involved with any of this stuff .... it's just the knowledge of the coils and how they interact with each other....

[talking to cameramen:  ?you can shut it off now and will go the other device?]

Seeing what Steven said about his first TPU is quite amazing.

1)  Takes energy from the MAGNETIC field of the earth.   Why not mention ELECTRIC field?

2)  The device TUNES to the right frequency of this earth magnetic field.  So it's a tuned device.

3)   Uses "bailing" wire, which to me says it's IRON wire

4)   Uses no "mass  circuitry" just knowledge of the coils and how they interact with each other.  (note "with each other", why not with the magnetic field of the earth? hmmm?)

5)  The device depends on orientation,  so I believe it when he says it's tuned to the magnetic field of the earth. It's like an antenna, and antennas depend on orientation.

6)  Takes a magnet to start it

7)   He speaks of a jet turbine effect, he seems to understand it involves a "lag" or delay, maybe even rotation.

etc..

I just made a connection. I haven't recalled Steven ever saying MY device. Only this device, the device, a device that I have. What if, using these habits of refering to the device, he isn't being honest to who made it. What if there is a secret engineer that we don't know about! Maybe he is just being made to say stuff. This would be the reason he couldn't give out anymore information. This would be the reason he wouldn't want to contact us. GUILT! It's all regret about claiming to be the inventor! With this situation, the government could have assassinated the real maker. We have been running in circles trying to figure out why this guy would just give up on a device that would change the world forever. I still think money wasn't the reason he gave up. He could have made even more money on selling the devices in his own buisness. Yes, this is a very large hypothesis, but think about it. There is no way he would just shut up about it.

Compare this to the last video where he doesn't say it is tuned to the earth's mag field, and where he states that the energy comes form within the device itself.

Also, he turns on only two frequencies for the large ring.

...and they all have a similar thickness to the ring itself.

He's got the dragon in a "knot"...

I have been seeing these posts about TPU all over the forums here, but most of the time would ignore them because it didn't spark my interest. In any case I have watched the videos EMdevices referred to on Google Video to see what all the fuss is about and learn more about TPU and this "mysterious" Steven Mark fellow.

Sure thing the videos are of poor quality and to make a digression a bit, isn't that always the case? Just like the UFO videos, where things are either too far, too blurry or just bright lights in the sky. Well these TPU videos are right up there with the UFO ones, and there are lights in them, too. What's portrayed might be authentic and it does look impressive but then again isn't that always the case or the intent of the presenters?

Not passing a judgment here, I'm really not, but the only thing that stuck in my mind after watching the videos was that he said the unit uses Earth's magnetic field to draw it's power, and right there I felt it was a dead-end. If I recall correctly our scientists tell us that the Earth's magnetic field had reversed itself many times in the past and it is bound to happen again in the future. It is something, they say, that happens naturally and in cycles. Common sense tells me that this one, or any kind of device relying on a connection to the Earth's magnetic field is bound to failure and as such should be deemed unreliable.

Yes, it could be one of many backup alternative energy sources, if it can be reproduced and harnessed by everyone, yet I am not sure if anyone has thought about the Earth's magnetic field failure before since I did not read all the posts (way too many). I'm kind of a guy who worries that one morning we'll wake up and the gravity would reverse itself and everyone would fly up into the sky and out into the open space. Nothing is ever set in stone and taking things for granted might prove to be detrimental at the end...

Post by: EMdevices on January 06, 2008, 12:28:39 AM
good points guys,

we should just state for completion that Steven Mark, abbreviated as SM on this forum,  has many other types of devices.

The videos can also be viewed at the same websites, and sadly they are of a lower quality, however, it is evident that they reveal something quite extraordinary, if indeed it is.

Like Grumpy has mentioned,  in the other videos, he seems to say something different, but again, he is talking about a different device altogether.   

Are these devices related?    It stands to reason that they should be if invented by the same guy, they certainly look about the same, meaning round, but then again the function can be somewhat different.

I want to explore more the idea that these devices tap the MAGNETIC field.

It is obvious that the TPU is composed of two loops of twisted wire, this makes sense.  They seem to be loop antennas and they're designed to pick up MAGNETIC fields, not electric.

But the idea of an INHERENT FREQUENCY, can be somewhat confusing.  On the one hand, there are electromagnetic fields of different frequencies everywhere around us.  But when speaking of the magnetic field of the EARTH, we think of that as STATIC, not changing (perhaps very slow over year as we are told or with major geological events)   So what exactly does he mean?  Is he using the term loosely to just mean magnetic fields? with the reference to "earth" being made just because we obviously live on earth? 

It' possible, but one thing is clear, he mentioned MAGNETIC FIELDS, and the configuration of the device matches, since he is using LOOPS of wire.

The thing that has me thinking is why doesnt the TPU work upside down?....i mean whats within the TPU that defines its top and bottom if its merely coiled wire?.
Title: Re: The First TPU
Post by: EMdevices on January 06, 2008, 05:10:59 AM
yes Chad, this phenomena is very interesting. I believe it shows that the device operates like some sort of an antenna, since only antennas depend on ORIENTATION.

Everything SM has told us through Lindsay also makes sense (about the 3 signals adding, etc..) but this simple first device of his, seems to not follow those rules.  Maybe SM learned a lot of lessons from this simple device, and perhaps learned what the real source of energy is, so he could extrapolate and make the larger TPU.

I really want to understand this little TPU, and if we had a better video we could gain more insight into it.   

Whoever posted those initial videos at Google and other places, if you read this, please make a better copy of the video and post it here.  It will be of tremendous help.

Nothing to do with orientation. Only gravity or energy from the sky defines top and bottom.

@Tosky

well "Maybe" if the device is feeding from the earths magnetic field and electrons are traveling around the collector coils in the "correct" direction for the device to operate, so when the device is flipped over the electrons will be traveling in the opposite direction to draw the magnetic field... so the TPU will begin to stall, also if you notice in the video when he flips the device over the magnet he has attached lets say he has it oreientated with the earths magnetic field.. so this also is on the opposite side to wich it started reversisng the poles in relation to the earths magnetic field.

@Chad
The tornados always screw to the earth not to the sky. It is because gravity. If a vortex is needed and happening in the TPU then electron as elementary particle should also screw to the earth.  But I don't know whether tornado rotates only clockwise or both direction. If only clockwise there may be some physics related to the TPU.

@EM

Good work on the transcript.

Notice in the presentation, he put the magnet on first. Then he fiddle around on the meter pushing buttons. Why did he spend so much time on pushing buttons on the meter. This should have been set to DC volts before since he new he was doing the demo and he must have practiced the demo a few times before video tapping it. This gave the time for the TPU to increase in voltage before the meter was on and showed 61.5 volts. Also by doing this, we could not see any starting voltage readout, like maybe 12 volts or 9 volts.

Come to think of it, he always starts the units before he looks at the voltage. never see the voltage with the unit off. I SM leaves nothing to chance, there is a reason for this.

1) Notice when he says the voltage is "down now to 13 volts 12 volts it stops producing electricity". We should look at this sequence VERY carefully and count the time it took for the voltage to drop. I tried looking at the meter readout but the video is again the craps. He had enough time to say 13 - 12 volts. It can give the impression that the voltage never dropped below this level since he said at that point it stops producing.

2) 61.5 volts - 25 watts = 0.406504065040650..... amps.
A little less then half an amp.

3) Dead Give Away when he says....
"it doesn't contain any batteries capable of generating the amount of electricity that you're going to be witnessing here..". This is another way of saying that there are batteries to run the circuit, but never enough to run the whole output you are witnessing.

4) In general the first TPU demo was not long enough to prove any OU.

5) Again. Circuit is inside the ring. Always a constant.

6) Son of a gun - the magnet position...............
You can see near the toroid there are two bailing wires coming out in front of the toroid like a left and right magnet stand on which he put the magnet. The magnet is actually about 1 inch away from the toroid. I have prepared some drawings below to explain what this is being used for physically.

One magnet field is "probably" going around a top bailing wire and the other field the bottom bailing wire. Both wires are around the outer rings and this is why he is using a silicone type of adhesive to keep the wire in place. I don't know if the discs are metal or not but would guess not.

I have tried many tests with bailing wire with a magnet and or a coil and the field goes all the way around.

The company that holds the patents is UEC, some company in the Philippines or Australia.  And they're not doing anything with the information, just siting on it.

Why?   Here's some possibilities:

1)  Technology does not work.

2)  They have been bought out to keep quiet.

3)  They're ignorant and don't know how to implement the information they have.

4)  This is all a fairy tale, go back to sleep  :)


Bailing wire is made of iron, so it's thin iron wire, with or without insulation on it.

Hey EMDevices,

I had no idea that this company was outside of the US, so now I started searching for patents outside of the US.

I think they are (or were) in Australia.  See attached image, and note how I cannot access their patents (proprietary and limited).

Hmmm....

Why are we letting this awesome thread sink to the bottom   LOL  :D


It contains all the clues we ever need, straight from the guy who did it.

You know he did mention that there is a little bit of OU when current is caused to flow in a wire (from his letters to Lindsay)  and he said that is all he had when he set out to design his device.  It might not be much but its OU he said.


You know that's very true, if we find a small source of energy we can then start to work at it and we have a clear road map on what to do.    From what he says in this first video, it sounds like he is tapping energy out of the radio spectrum, no matter the frequency, even if really low.  So it's received energy it sounds like.  If this is the case it then requires extremely high Q filters to build up enough voltage so that it can be usable.

Can somebody locate this paper in pdf format?

It's very interesting and applicable to the TPU since bailing (iron) wire is mentioned in the video, and small fluctuations of magnetic field can have a drastic effect, as the paper mentions.

Hi EM,

Here is a link to a paper (which is worth reading in itself) which mentions as a reference #2 the original paper from which you have the first page. It must have been published in the Proceedings of the Royal Society vol. 137, year 1937, page 651.  If so, this publication could be found in science/university libraries even via inter-library services from abroad.

According to this paper http://www.sensorsportal.com/HTML/DIGEST/march_06/P_61.pdf
the effect is a Giant Magneto-impedance effect and possibly this effect must have been observed back in 1936-37.

Of course the original paper would be a good reading for sure.

Post by: EMdevices on January 22, 2008, 07:48:49 PM
thanks for the links gyulasun.

I've been thinking along the lines of NEGATIVE RESISTANCE OSCILLATORS lately.

Can somebody get excited please !   LOL  :D

I've also been reading up in my Electronics book about oscillators, negative feedback and the stability criterion  (phase margin, gain margin, Nyquist plots, etc..) 

So what am I doing?  

I'm trying to purposely create and engineer an unstable system! 

At this point I don't care where the power comes from.  I'm engineering the unstable system to self oscillate, and if I can find components that deal with magnetism, so much better.  I'm aiming for no ELECTRONICS.  Just coils, magnets and capacitors.

Now I'm thinking the iron wire and it's resistance succeptability can play right into our hands as a negative oscillator.  Why?   Well because it's so sensitive to an external field. 

Imagine the flowing current passing through the iron wire also passing through the external helix coil surrounding it.    It will affect it's own resistance.   As it increases, the resistance goes up (since the magnetic field increases) but its driven by voltage so in essence we might have a negative slope to the resistance profile.   If that doesn't work there's other ways to explore, double balanced coils etc..

just thoughts that I'm currently in love with.

EM
Title: Re: The First TPU
Post by: EMdevices on January 22, 2008, 08:07:10 PM
This is what I'm thinking.

Could there be a portion of the V-I curve where this exibits a negative slope, hence a negative resisitance that can be used to create an oscillator?

EM

P.S.  Keep in mind that in the first TPU, the iron wire is in a loop form.  Also, we can even reverse the iron wire and the copper wire since the fields are such that they work the same.  (all we need according to the article above is to have an AXIAL magnetic field, which will affect the resitance drasticaly)

Also, recently scientists discovered there is NEGATIVE RESISTANCE at the boundry between magnetic domains (at the microscopic level) This is encouraging to say the least.  The reference to the "bailing wire" in the video is starting to look more and more like a vital clue.

Hi EM,
great ideas.
This reminds me of an experiment I still want to do:

Build a coil of insolated iron wire.
As it is iron a permanent magnet will be attracted to the
inside of the iron coil.
Now see, how much inverse current you have to drive into the iron coil
to cancel out the magnetic field attraction, so that the magnet can move through the
coil without being attracted by the coil?s iron.

You could probably also do this by wrapping copper wire around
the iron wire.
Then use the induction voltage from the iron wire to store it in a capacitor
until the magnet has moved into the coil and then use copper wire
around the iron wire to pulse this from the cap to propell the magnet
out of the coil again.
Makes me wonder if you need less energy to propell the magnet out of this special
coil as is produced, when the magnet goes into the coil...

Also from my previous experiments I have seen,
that iron coils don?t produce any Back EMF pulses
and the electrical current heat of the coil is attracted to a permanent magnet sitting on one coil end...
Title: Re: The First TPU
Post by: turbo on January 22, 2008, 10:02:51 PM
hey that looks like the little motor experiment i did a while back.
when you turn a stepping motor, you will find that there is a what i call "magnetic moment"

at first the field resists being compressed, and when you drive it futher it actually repells from this magnetic moment.

the idea was to cancel out this first half sine resisting force by feeding in an inversed signal into the coils to cancel the first half of this resistive force, and then when the motor is over it's resistive point ,it only is left with this repelling force, resulting in an acceleration only......

Permalloy is used in magnetic sensors. The magnetic domains of permalloy thin film deposited on a piece of silicon must be unidirectionally aligned to avoid a very noisy sensor.

A layer of conductive material is laid down along the permalloy sensor elements, in parallel, to allow a method to receive a sharp pulse of current. This sharp current pulse provides the necessary magnetic field pulse to align the magnetic domains in the permalloy sensor elements.

Barber-pole straps over the top of the permalloy elements are added to make the sensor more stable. These straps add stress lines onto the permalloy elements where the domains are more likely to line up perpendicular to the barbor-pole straps.

Futhermore, during the wafer-fab process these sensors are exposed to a dc magnetic field while they are getting annealed.

The sensor is still susceptible to getting into a noisy state from short exposure to a heavy and randomly aligned magnetic field. Degaussing coils work pretty good at getting these sensors into a noisy state. We found that a modified soldering gun with the soldering tip replaced with a heavy copper coil worked wonders at getting the sensors into a noisy state. The more random the magnetic domains are in the permalloy sensor elements the more noisy the sensor.

Because the sensors we had fabricated did not have the conductive layer deposited for the domain alignment we would manually align the domains in the permalloy by placing a magnet's pole in line with the sensor element with the proper polarity to be compatible with the barber-pole configuration.

Aligning the magnetic domains in the permalloy makes for a very clean sensor. Randomally aligned domains make for very noisy sensor elements.

Permalloy, however has nickel in it which allows for a near zero magnetostriction. But I'm thinking magnetostriction would add to instability which may be desired in this application.

Take care.

Now if you have two speaker magnets that are joined by a flat square wave shaped coil of iron wire.....

At each bend of wire extend beyond the magnet to hide the bend from the internal workings between the magnets.

Sorry - thinking out loud here. I've seen this NR activity in my Cook coil experiments. It does indeed work. I attributed it to GMR but it equally fits NR.

speaking of magnetic resonance,

I was able to obtain a small DC voltage from an oscillator and a magnet.

Look at the figure below.   It is a Colpitts oscillator with the typical tap between the capacitors.  It's a bit modified from the typical topology, but it works.

Here's what I did:

   While it was oscillating, I brought a ceramic magnet close to the small toroid inductor, in the same orientation as we see in the SM video  (from the side, flux horizontal)

As the core saturates,  I can see on the scope the frequency increasing, which is expected.   However, at a certain point, a type of heterodyning appears, and I see an amplitude modulation start to appear on top of the signal, sort of like a beat frequency.

As I approach the magnet even closer, that's when it happens.   A sharp drop in the DC offset by maybe 1.5 volts.  Even the slightest movement of the magnet closer or farther,  will end this effect.   It only occurs at a particular point of saturation of the core.   I believe the Larmor precession frequency might have something to do with it.  Rotation of fields might be occuring where the flux cuts through the coil widings IN THE SAME direction, so a DC generator effect takes place. 

I have more experimenting to do, changing orientations, etc..  but it's very encouraging right now.

P.S.  I added another figure to show where the Oscilloscope connects and the flux orientation.  I haven't experimented with the different directions yet, only N or S, and both work.    Now,  if you look where the scope connects,  the DC offset at this point is 10 volts or close to it.   While in operation and oscillating a sinusoidal waveform is imposed on this DC offsett.   So, when the effect takes place,  the DC voltage offset of these oscillations drops suddenly to 8.5 Volts.   Quite impressive to say the least.

Hi EM,
I would be astouned,
if you would get 11.5 Volts,
but the lower voltage is maybe just a change in the working point current
and as the capacitors are a voltage divider there might be just lower voltage on them
in the new working point,
or am I wrong ?

I did more tests today.

I connected the scope across the inductor, and sadly there was no DC voltage.   So, I believe the DC voltage might be occurring due to circuit loading or phase changes or something like that.   (Stefan, the drop is about 1 volt and a half, not 11 volts, that would be great  if possible. I think you are right, it's the voltage divider effect now that I think about it.)

The orientation of the magnetic field seems to also work at 90 degrees to what I showed on the circuit diagram above.

Now,  looks at the attached pictures. 

You can see the heterodyne phenomena taking place.

So once again, the heterodyne takes place when I bring the magnet close to the ferrite toroid (it's small 1 cm diameter)

In the figure above, the magnet is laying down on the carpet farther then where this takes place  (I froze the waveform on the screen so I can take a picture)

So we seem to have a beat frequency of about  1/15us = 67 kHz

And the main frequency of about 1/3us = 333 kHz

So does this mean we have two signals that interfere with each other,  let's say   333 kHz  and  266 kHz  ?

I wonder why these signals appear.   Right before this occurs I just have the 330 kHz signal, and poof it breaks out in this new mode of oscillation as I move the magnet just a tad bit closer.  This could be modes of resonance where the inductor maybe starts to resonate with the other capacitors on the board.  Who knows, it's quite interesting anyway.  I should say that it's common knowledge that saturated cores produce distortion and harmonics, but I'm not seeing harmonics here, something else is occurring which might very well be resonant mode locking.

I'm anxious to see if Jack Durbin's original video might be showing this first TPU device.

This device and what Steven Mark says about it, is related to an antenna capturing the magnetic waves  by being tuned  (the magnetic field of the earth "which inherent frequency" like he says in the video)

Now, Jack said he was hired to work on wireless power transmission.   I find this interesting.
