TK device, TPU.. Only enter if you seek truth. Cause here it is...

OKOKOK..  It's going to be long, but I will show facts, pics and information on what these 2 device principle mode of operation is.  This is not theory, this is a well little/known subject.   Nuclear Magnetic Resonance and Proton Precession Magnetometer are basically the same rock but different color.  Things that are involved are RF signals that are used in different frequency's pulsed  into or thru an object.  That object or sample can be anything from water to Metal.  A strong Pre-Polarizing Magnetic Field.  The earths Natural Magnetic Field.  3 Coils are used in the NMR and the middle coil has 3 parts to it.   If you have worked on or seen the videos and know a lot about them then watching these videos should tune you in to what is going on in the TK and TPU devices..  There are 10 of them, but the first 8 are the ones pertaining to this subject..  The rest follow this one on the right side column..

This Video is of the Steve Mark TPU.  This video hasn't been seen much.  They talk a little about how the TPU works, Using RF pulses and Ceramics, which are superconductors.  at 3min. 45 sec. Steve runs a magnet around the bottom of the TPU.

Here is a web page with all the info about this process.  Take your time and study this and If you don't think This is right just leave and don't post BS about this having nothing to do with TK or TPU.  This is facts only and the facts speak for themselves.

NMR and the process of Spinning Nucli for energy Release

Coil Arrangement

Center Coil...
   Transverse Oscillating Magnetic Field coil, that is used to disturb the Nuclear spins from their natural equilibrium state.  This coil can also be used to detect the signal in the NMR.  The signal produced is an Oscillating Voltage.  Thats where the Energy is.
Outer Coil....
  The Pre-Polarizing Field Coil is used to produce a large magnetic field.  Just before the pulsing process starts, this coil is turned on for about 5 seconds.  It's field was 350 times larger than that of the Earths magnetic field, which makes the signal 350 times larger than if you just used the natural Earth magnetic field.
Middle Coil...
   This is the coil with a varying magnetic field that vary  in 3 or formidable directions. It is also a multi-part coil.(3 coils in one I believe) This coil has 2 particular functions.  By applying a very small current thru these coils, we can provide smoothing of the Earth magnetic Imperfections.  Anything can change this field which would result in the process stopping or limit the decay of the Nucli.  If someone were to hold a ring by the coils, it could dampen the process.  So we can improve the Earths magnetic field to obtain a much stronger signal from the object in the center of the coils, used for transmutation.  Using Shims in this gradient coil can make or break the operation.  In the video I watched, he used 3 voltage inputs into this coil and they range from just 2 or 3 volt up to 7 or 8 volts.  Depending on what the sample is..  The second function of this coil is that it can adjust the field anywhere you are on the surface of the earth.  Tunning has to be done, even moving the coils down the street can break the tunned coils and you won''t get shit out of it.  The scientist used a computer program to automatically tune this coil.

   The secret to getting a good strong signal and a longer rate of decay is called the spin echos.  The initial 90 degree pulse happening at the start of the process right after the 5 second pre-polarizing field sets em up to spin out of their newly aligned vectors. Using the transverse Oscillating field to create a 180 degree pulse right after the initial 90 degree pulse and you do this by running the pulse twice as long.  So the 90 degree pulse is say 1 millisecond long and the 180 degree pulse would be 2 milliseconds long.  The spin echo produced by the 180 degree pulse is a very good tool in the process of getting the metal to decay .  So trial and error would be easy enough to find the right pulse sequence for the metal used in the device..
  Field Homogeneity is very important for getting the best rate of decay.  The narrower the spectrum spike frequency, the stronger and longer the rate of decay.  Shimming is the easiest way of going about with tuning your middle coil.  The spin of the nucli is called Gyromagnetic..  When Steve Mark said you can feel the TPU pushing back on your hand, like a gyroscope does, that is because he has all the Nucli spinning all together in the same direction.  Thats where the little Magnetic motor action comes from..

Here are a set of Pictures with the Coil parts taken out of the device..
The first pic is the TerraNova coils pulled out a little of the device.
The second picture is a close up of their Varying Magnetic Field Coil, the middle coil.
The third picture is him showwing that by just putting the wrench next to the device can stop the decay from producing a strong signal.  Fourth picture is the center coil, which is the Transverse coil which is a solenoidal type coil.

Now this picture shows him holding a wrench next to the NMR and it stops the decay reaction by disturbing the magnetic field..  This is  seen and heard in both the TPU video and the TK2004 video.  This again is the TPU video and steve asks if the guy is wearing a ring.  Now if he introduced his metal ring into the fields why its running, it can stop or slow the operation down and he would have to restart the tpu again. Fast forward to 4min. and turn up the volume.

Now the Green Box video, The 2 main guys that handle the box and turn it off have no watch on or rings.  Now thats not much for proof  but when you start the NMR reaction you have to Pre-Polarize the Magnetic field so that the Vectors of the Nucli  get into their proper alignment for the Nuclear Spin to work.  In the TK2004 video he plugs in the inverter for about 10 seconds before he flips the switch. Then he unplugs it.  Now that would be the steps in order to start the device.  Its at 17min and 30sec and also at 20min 45 sec..

I WILL POST MORE INFO SOON

I know everyone has seen the Mcfreey Papers, but here is a very good detailed informative document on this very subject.  It has diagrams and the 2nd copy of Mcfreey's papers is a bit different and I am not sure if he updated it or someone else did, but here it is.

Be safe, some metals put off bad effects and radiation so choose a good metal to pulse..
