Towards Realizing the TPU
« on: September 04, 2008, 02:46:35 AM »
This ?thread? is about gaining an understanding of a given body of information and aims to develop from it a working conceptual design of the TPU in line with how Steven Mark originally conceived of and built his units.

Some may see the value in this approach, but many will scoff at the apparent absence of real bench work. To them I will only say; get over it or move along. Bench tests and verifications may be performed with this development as required (and possible) along the way.

Although the material indirectly supplied by SM is voluminous, very little of it is useable as a means to solving the TPU mystery. What can be used of it and other incidental sources will be, but the primary inspiration for this development is the material posted by Spherics at the overunity forum: http://www.overunity.com/index.php/topic,4297.0.html

The Spherics material can not be validated as authentic and true, but to date in my view it represents the most lucid description of how SM's TPU?s might work, and provides actual hardware descriptions which can be tested. Far from perfect and most likely incomplete, but it is the best starting point ever presented on the web. Sadly, Spherics focuses mainly on an improved model and exotic physics explanations without making much reference to how the original SM designs (in terms of hardware) fit into this picture.

This thread will mainly focus on reverse engineering the nuts and bolts of Spherics' material in an attempt to unravel the SM designs, but will inevitably cover aspects of the Spherics design as well. There will be occasion to scrutinize the theory Spherics put forth, with simplified or modified alternatives proposed.

Consider this a work in progress. New material and/or edits will be added as time and insights permit. It?s also not polished, nor error-free.


Thanks for the positive feedback guys!

I hope the minimum to come of this contribution will be to spark a few folks into thinking about this device in the context that it IS DOABLE. Optimistically, it will come close to establishing a sensible and practical framework for which to springboard off in the pursuit of cracking the TPU mystery. Ideally, the final revision of the document will contain all that is needed in terms of practical information to achieve a working build of any one of SM's TPU devices as well as the Spherics design as given.

Here is revision v1.2 (already posted): http://www.overunity.com/index.php?action=tpmod;dl=item110
All document revisions after v1.2 will be posted in this thread.

The harmonics SM was referring to was what Spherics referred to as the NMR of iron.  Pulse the three coils at the NMR of iron and the overhead coil at 3x the other coils (harmonic).

Are you sure of that?

What is the NMR of iron? At what B-field strength? (it varies with the B-field).

That part of the explanation didn't make a lot of sense.  I think EMDevices had a lot to say about it when it was first posted.  Maybe he just meant that frequency range, since it is a range based on the B-Field strength as .99 stated.

Quote
1. Introduction Nuclear magnetic resonance (NMR) is a method sensitive to the local properties of
magnetic materials. It has been applied to YIG containing various substituents or intrinsic substituting
defects on iron and yttrium cation sites [1–6]. NMR spectrum of 57Fe nuclei for an ideal YIG structure
contains a single d-line assigned to iron ions in tetrahedral crystallographic sites and two lines a1 and a2
having integral intensity ratio 1 : 3 which correspond to octahedral sites. Spectrum of a-sites splits into
two lines because of the magnetic nonequivalency of a-sites with respect to the [111] direction of magnetization.
Resonant frequencies are proportional to the local magnetic field at iron nuclei by gyromagnetic
ratio 1.377 MHz/T
.

From Becker:

http://books.google.com/books?id=lV387lG0u_kC&pg=PA29&lpg=PA29&dq=Larmor+frequencies+becker&source=web&ots=d6cEdzKWKu&sig=uc9vrLqKIHvROccPr-MG-5Jn3F8&hl=en&sa=X&oi=book_result&resnum=2&ct=result#PPA382,M1

NMRF of Fe: 3.2378 MHz @ 2.35 T

Which works out exactly to the above 1.377MHz/T.

10k G = 1T
Earth's magnetic field varies between 0.3G to 0.6G; Ave = 0.45G

0.45 G = 45uT

The NMRF of Fe in earth's field ~ 62 Hz ?

The question in my mind regarding iron's NMRF and the mention of it in the spherics posts has always been:

What does the NMR frequency of iron have to do with the pulsing frequency in spherics' design when he vehemently avoids the use of Fe, including the use of the iron delay coil?

(The iron delay was for a different design using different parameters.)

Maybe with this geometrical arrangement, NMR of iron works.

The delay coil's purpose was just to introduce a delay on the cheap. Any "slow" conductor should do the job.

Spherics spoke little of iron's effects and purpose (aside from providing a delay) in the device and I am not convinced that using its NMRF is integral to achieving a successful design, (geometric or otherwise) esp. since his tetrahedral device contains no iron. Fortunately, we have function generators/oscillators etc.

Spherics left us with some good material, but like all others, there are inconsistencies and gaps, unfortunately. I am not complaining though ;)

btw, I suspect Steven "liked" 35.705 kHz for his 15" TPU, because using 35.7806 kHz is the exact frequency that would cause runaway.
