Graham Gunderson?s dragless generator patent, Lenz law violation !

[jake]

I opened one up and was disappointed that all they were was a ferrite core about 4 inches ID and only one coil about 18 guage wound around the core.  This explained why there were only two leads instead of 4.

Don't throw 'em away yet!

Current transformers require the primary to be looped through the hole in the core.  If yours is 800:5, you take your primary wire and loop it through the hole 5 times.  You can effectively get different ratios by changing the number of times you loop your primary through the coil.

Note that to put one turn on the primary, you must stick the wire through the hole two times.  If you put the wire through only once you don't have a complete "turn" on the primary.  You must have one loop through the device to have one turn.  So, to get 5 turns you have to go through the hole 6 times with the primary lead.

I have only ever seen this type of transformer used to sense motor current in large ac motors.  The motor lead is directly wound through the device to form the primary.

Hello Everyone,
This my first post here at Overunity.com, I have been developing a version of the Gunderson solid state generator for personal research purposes.  I'm very excited about this generator, and yes Tao, I feel that THIS IS IT! too.   

I have built a linear 'proof of principal' of the Gunderon generator. Consisting of a linear silicon steel laminate core containing 5 magnets and 2 input coils the output wire is a single pass of insulated braided copper wire. The magnets are 7mm x 3mm neo's I had. The core is a stack of 21 11mm laminates from a 12v 4amp charger transfromer and the input coils are wound from the primary windings of that same tranformer. I only ha to drill 3 holes in the laminates since they already had one at each end. I used cyanoacrylate glue and a vice to make the stack, solid.



The purple and green wires are for input.  Only the two copper coils nearest the center of the device are hooked up, I wound all 4 input coils then I realised that the 2 outer ones would heat up because they were just pushing against the end magnets which are unable to shift there flux  because they lack a "balancing magnet" because this is a linear  device not a ring .  Sure enough when I powered it up the outer coils got hot quite quickly while the inner two remained cool. So I disconnected them. The use of 5 magnets is nessesary to allow the device to have a functioning middle section with magnets that have their flux divided equally in two.





I have meassured 184mV RMS from the output of this device when excited with .6v AC 50Hz. Small output I know. However I could make consistant voltage spikes of 3 to 4v when I rapidly connected and desconnected the input power and occasionally higher spikes in the 14v range. Despite what may seem like a tiny output I am encoaraged.  I made these measurments on a quality digital ossciloscope at a freinds house using only a AC/AC transformer at 50Hz to excite the input coils.
Since then I have used a small audio amp to power the coils. Connected to the soundcard on my PC and a tone generator to generate a square wave at different frequencies. Unfortunatly my multimeter is not accurate enough to get a reading. But I have had a alot of fun testing the resonant frequencies of the device. I am able to feel the magnetic field occilations by holding a magnet near the device. Or sticking a laminate to the magnets to get a audiable feedback of the vibation. The qualitative sence of vibration strength of the magnet I was holding seemed to peak around 200hz, at least on the level I could feel. Then there were overtones at heaps of frequences up to over 64 0000Hz that seemed to peak the vibration and or sound output. All I can do without proper equipment is make qualitative observations and work on instinct

My linear proof of principal device has many inheirent flaws, Yet I am seeing an output.  I used magnets that are far too small based on the ratios I could determine from the patent diagrams and the silicon steel laminates that make up the core seem to block the field so much that the flux is barely noticeable when I place an iron nail in the holes that carry the output wire. Also the linear configuration means that only the middle 3 holes and magnets are functioning as they would in the toroidal device as the magnets at the ends  have no balance magnet and thus their flux dose not so easily shift.

The vibrating magnetic field that can be felt when one holds a magnet near the operating device is very large for such small input coils. In fact, if the input coils are excited without the magnets in place. The field that can be felt by holding a magnet near them is miniscule. Demonstrating to me that this configeration is very efficient for shifting a large perminant magnet flux with small input.

I think that a critial aspect of this design is in the way that the magnets are posistioned relative to each other. Each magnets flux is equally divided between 2 other magnets on the other side of the core, so that the 2 rings of magnets are effectivly balancing against each other and only a small nudge from the input field makes one flux path FAR MORE favorable so the flux is effectivly on a see saw that can be actuated with a small input.

Given this reasoning the Torroidal configeration is nessesary to allow all magnets to be balanced.

Hartiberlin; my inital feeling and answer to your earlier question is number 2  One big hole for output, diameter of 1/3 the height of the core. but with an output wire that makes many passes around the core untill the hole is filled. I am not skilled in transformer coil calculations. Perhaps someone can help. I want to make input coils of 4 to 8 Ohms so that they can be driven through an audio amp for inital testing untill the resonant circuit can be implemented. I figure that multiple passes or turns in the output coil will improve power out as more copper and or turns  is present to collect EMF. The permiabilty of the core seeems to be a major factor. I belive the patent talks about resin bonded iron cores because the core needs to be less dense then solid iron to allow the magnetic flux to extend into the output coil holes and not be effectivlly shielded.


I intend to build a actual torroidal device with 25mm neo cubes and an epoxy resin/iron powder core. With 8 ohm input coils to be excited with an audio amp with sound frequencies from a tone generator on my PC.

I have some questions, perhaps someone can help.

1    I want the input coils to be efficient at creating a magnetic field. I want them to be 8 Ohms and operate at power levels from a 50 watt RMS audio amp at full volume. What thickness and length of wire should I use.

2    Is it true that a coil with fewer turns will be able to operate at a faster frequency then a coil with more turns? / if so why?

3    Where can I get Iron powder in Australia. I have purchased Iron Oxide powder for coloring concrete, it is very magnetic, am I correct that ferrite cores are made from iron oxide?

4   Dose ferrite saturate at 20 000 gauss? / or dose saturation relate to mass of material ect.


Thanks very much in advance, I'm so glad I have found this forum. Good work Overyunity.com

Hi,

Please be aware that this device will not be Over Unity unless a key factor is present.  Since we are filing a Continuation in Part on the pending patent application, I cannot reveal it.

It will not be Over Unity with ferrites.

It requires a very special component.  That is all I can say about these issues until the patent process is further along.

A working device was constructed prior to filing the patent application.  It far exceeded unity.

More than two dozen prototypes are part of our present laboratory development program. 

The published photographs are of a different invention.

That is too cool.
Thanks for posting the pictures, great visual of the patent.

It's got to make you feel good that these guys are trying.  Has Hal Puthoff (ETI) started the testing yet on your device?
Hope all is well and godspeed.
