Daniel McFarland Cook Electromagnetic Battery
« on: January 15, 2013, 10:50:37 PM »
Has anyone successfully replicated this? I been working with a downsized version with each iron rod only being a foot with the primary wires being 28 AWG with both being the same amount of windings (I do not remember the amount for the primary but I definitely remembered thoroughly checking to make sure the windings were same for both of them) and 14 AWG solid wire with 141 windings on each rod and I definitely connected the primary wires to the secondary wires of the opposite rod and I created a helix test jumper to "close" one end while the other end having jumper leads to connect to the battery for start up along with a potentiometer being connected in a rheostat fashion within the series and I even put in a capacitor to "handicap" it but I still got no reading on my multimeter for voltage or amperes.

Also I am thinking of doing it again but this time with annealed iron wires as the core and I am wondering if I can fold the wires for condensation purposes, since his patent said the preferred should be 2; 3; or 6 feet in length, or if the wires have to be straight

I wouldn't discourage anyone from trying as things are often left out of patents but here is one person's results I found just Googling it:
Aug 16, 2001 -
 - Core material ordered, recieved, and cut to length.
 - Primary coil forms, have cardboard mailing tubes, 3 inch OD, 1/8 wall.
 - Secondary coil forms, have cardboard shipping tubes, 5-1/4 inch OD, 1/8 wall.
 - Primary 22 gage magnet wire, ordered, and recieved.
 - Secondary 12 gage rectangular .032 x .144 magnet wire, ordered, waiting for delivery.
 - Calculate device will weigh about 70 lbs.
 - Making plans for simple coil winder.

 Aug 20, 2001 -
 - Received 12 gage rectangular magnet wire, actual measurement .037 x .147 inch including insulation.
 - Learning how to wind rectangular wire.

 Aug 28, 2001 -
 - Been unable to work on project for the last 5 days due to social obligations.
 - Simple coil winder has been drawn up.
 - The winder is a ring that the tubing rotates in. A slot holds the wire on edge while being bent.
 - Have found material for coil winder. Friends are machining the winder parts.
 - Goal is to wind coils this holiday weekend September 1-3, 2001.

 Sept 2, 2001 -
 - Inner coils are wound. Pictures
 - Will make spacers for between coils and wind outer coils tommorrow.

 Sept 3, 2001 -
 - Outer coils are wound. Pictures
 - Need to glue things together and do wiring.

 Sept 8, 2001 -
 - Coils are epoxy glued and taped. More Pictures
 - Base boards are sawn like in a jigsaw puzzle. This allows coils to stand 1/2 inch apart.
 - Coils are wired to a terminal strip, ready for testing tomorrow.
 - Connected wires, waved magnet, nothing happened. Magnet was quite small, did not expect anything.
 - Will wind a starter coil tomorrow, see if I can jump start this thing.

 Sept 9, 2001 -
 - Ran AC current thru coils. More Pictures No power produced.
 - They creat a large magnetic field. A small rare earth magnet would vibrate when near coils.
 - Outputs 50 volts from an input of 115 volts 60 cycles AC.
 - Will do more testing, maybe with a pulse of 12 volt DC. (next weekend)


 Oct 2001 -
 - I can NOT make this device work. That does not mean that it never worked.
 - The device, AS I BUILT IT, does not work.
 - I can not say whether it might work if built to different dimensions or specifications.

 - I will continue to search for information related to devices that suggest overunity.

You are not going to make this device work by simply
Looking at the patent.
You need first to understand how patents were written back then
Compared to how we understand terminology today.
That being said, the Cook coil device works exactly like
Ed Leedskalnin's PMM
If you want to learn about the Cook coil
Build a PMM first.  Charge it, lock the keeper, break the contact
Make yourself familiar with the process of temporarily storing
Electromagnetic Energy


Now attach an LED across the coils of the PMM
And observe what happens when you break the contact


Once you do this, Cook's device should become clear to you
One other important thing to understand is this coil is an:
"Induction Coil" not a "transformer"
To us, they are the same. However 200 yrs ago this was not the case.
When this patent was written an "Induction Coil" was a circuit,
Today we use this name for a coil wound around an inductor.
These are two different meanings, as I will explain.


The induction coils of the past were a circuit that comprised of
An inductor with a coil wound around it (this is cooks device),
And also what was called an "interrupter".
Today this would be a switching mechanism
Either a transistor, connected to a 3rd coil wound on the iron bar
Or a hall-effect sensor, reed switch or the like, for the purpose of
switching the primary coil off when the iron is saturated.


The two coils then act as tank-capacitances for one another,
The primaries being driven by the other coils secondary impulse.
The flyback current through the secondary is derived from the
potential between E(0) and the saturation state of the iron core.


It's really quite simple, but for it to work, saturation must be very
intense (magnetically speaking) compared to the ambient field.
This is why the patent calls for 6ft rod, 1000 feet of wire, etc.

I guess the question is what kind of interruptor?  I'm starting to think along the crystal radio lines, with perhaps a variable cap or finding a small enough pF caps that will charge and discharge with the inductor's saturation.
I built mine with blackened iron/steel pipe from Home Depot and a steel core. Been sitting in a box for 4 or 5 years.
I'll have to have another look at it.
