Don't forget that Stubblefield and Tesla were friends at that time.  I am convinced after seeing Kapanadze's work that the spark gap was the make and break part of the device and Stubblefield knew it would adjust itself and really, if you want to look at it as I am at this point, the spark gap was used by Stubblefield the way we use transistors today.  I think he and Tesla used these even before the vacuum tubes of radio fame. 
So, I believe, and of course I could be wrong, that this was actually a precursor of sorts to the transistor circuit. His EER put out tremendous amounts of power and, as he said, without any deterioration of the metals used.  This told me that it is not a galvanic battery and not really a battery at all.

Take my electrode experiments...If I put the metals (carbon and magnesium) into a pot of water or other electrolyte, I would get volts and amperage but only for a while.  Being in the ground now for about 2 years and aligned properly, I can still see no real effect on any of the electrodes and they still light up stuff.

Now, how do you align an NS coil when you are only using one? I have no idea.  From the photos of his farm, it appeared to me that he used some of these devices in a grouping as they could be seen in a box all connected together.

Still a lot for us to try here for sure.  I just wish I knew more about how the Russian kapanadze was making his device work.  I'll bet we could get a real clue from that.

MW383,
Wow, what a great bunch of thoughts.
First, please give me the Cook reference.
I believe tesla referred to him in some of his lectures, and I would like th read or re read him.

I think your summary is an excellent one and worthy of some experiments.

I have been making experiments on an interesting circuit for many reasons, and I think the one reason that keeps me going is to learn - with my hands- how to take an existing pulse and use it as it is to make something useful.
It happens to be accumulating many inductors to achieve this. yeay!

Have you seen some of professor Lewin's lectures?
He is a brilliant teacher at MIT who has kindly allowed non MIT students to take part in his lectures.
It is one of the finest examples of open source I can site.
If you go to lectures from the spring 2002 8.02 physics lectures and perhaps start at lecture 16 you will be getting a lot of wonderful help.
Bill had recommended it, but not until recently was I able to watch the whole lecture.

I am not saying this to make you get busy, just it is incredibly helpful.
I believe this is the lecture which most closely deals with Faraday's laws and it explains so many of the elements we are dealing with that researchers of the late 1800's knew well. ... oh do check it out.

The only other piece I want to add is that in 1890-1910 the world had not yet grown accustomed to electricity and to say someone powered his house probably does not mean he had enough to run a dishwasher and hot water heater while he watched a dvd.
All those things were no part of a home until later.

But we do know how to conserve, don't we?

The power grid went off in my substation today. A teen ran into a main pole and it was out for 12 1/2 hours. They were quiet and calm hours, but if I were unable to detach from the life electric, it may have been hard.

I took advantage of this and made some scopeshots of the EER probes with and without the Stubblefield coils.
The basic probes although they were so dry they said 0.00vdc, gave me actually MORE ac volts than when the grid is up.
The stubblefield coils were very active as they always are - and I THINK not as high as usual.

Later, I rechecked and the stubblefield coils had a higher reading. One more like the usual.
The trouble with all these comparisons is that there is an overlap because of differences in time of day and other things.

I will try to put this info together and post it on the datalogging thread in the next day or 2.

Gotta catch up.

Now, I better make that food. It is 7:15 and grid or no grid, that food needs to be cooked!

thank you,

MW, Pirate, Jeanna and Protomom,
I read your last page of posts with great interest. MW, I really like your idea of the Stubblefield battery as an inductor.  Way, way back in the misty recesses of this thread, there was mention of the inductive properties of crystalline structure of rusted iron windings in the SEB, I think.  However, given the general crystalline structure of most metals (oxidized or not), might the idea of tapping into a coil's inductive properties in relation to the earth's magnetic field (and in play with energy from the sun) have merit?

Interesting work has been done to show that the crystalline structure within clear diodes has inductive properties. I wonder if Tesla's Radiant Energy Collector (US Pat 685 957) was based on his knowledge of the crystalline property of metal in his collector (laminated sheet of metal). Perhaps a laminated sheet and SEB coil may be tapping into similar inductive phenomea.  Just a thought...

I posted a similar comment re coil winding and the Stubblefield battery here:

Jeanna,

Well I have went back to experiementation. The one copper-iron coil that had the strange iron readings was verified to be defective. I switched to an analog meter and sure enough, it showed the problem. Strange deal that the digital meter didn't show things more clearly but live and learn....So with that out of the way I have been building simple coils and generally playing around.

Best magnetic results of a multi-layer coil are always when flow is unidirectional. So I will wind a layer, run an external lead back up to starting point and then wind the next layer. This always stronger than the ones where I simply wind the next coil in reverse / the opposite direction. These experiments based of Daniel Cook's patent. (real basic...but good for a beginner like me).

So in doing this, I went back to Stubblefield and realized that with open ended copper and iron coils (#10 wires), the only thing remaining to close the loop is the galvanic reaction itself through the water electrolyte. So you apply a resistive load across 5 and 6, this gets chemistry moving and we get our less than 1 volts and some milliamps. I am assuming that a weak magnetic field is being created here because of the electron flow through the coils. On my small battery, I get no detectable magnetic field. My battery way to small and only a single layer at the moment.

What kind of magnetic field are you observing with your full sized multi-layers batteries?

So the other thing I am looking at is optimizing my coil construction itself. I see many coil designs that have a deliberate space between magnetic core and the inner-most layer of windings. Everything I have done has had no space, other than paper insulator I am starting my first layer essentially right on the core shaft. I'll look into this further but it looks simply like the field need not have deep penetration into the core, surface contact with minor penetration seems to be a very popular configuration in the world.

Well I have to go for now. Will post later. I just wanted to announce that the strange iron results were no anomoly and strictly the result of a defective iron winding.

I'll dig out the Cook stuff and send when I get back to other computer. Your mention of conservation is important. I have a lot of people contacting me about alternative energy (mainly wind) and asking what system they need to power their house. When I tell them they need a unit in very high kW range that costs $30,000 they freak. This is where I lecture on conservation. If we meet alternative energy 1/2 way with some conservation, then the situation is more realistic. Some things are easy like switching to LED lighting. Other things like washing machines and furnace blower motors are a different story. Now if you mix alternative energy with conservation and also lifestyle changes, then you can still have some modern conveniences and also be sustainable. This is what I tell people anyway... Somehow I do not think they will be hand washing / air drying their laundry anytime in the future.

Thanks again!

I did not find this to be true.
I have mentioned that I made several nongalvanic coils and one was wound as you describe.
It flunked.
I was using an external battery and do not recall how I figured it flunked, but I never destroy my coils (intentionally), so I will try it again as a joule thief.

How are you doing this?
All I have ever tried was a compass and a bottle filled with babyoil and iron filings.
I never saw anything with the bottle. But if it is changing make and break by its design it would be too fast to make its field show in the oil.

It works a lot better on a joule thief when the turns are wrapped on the toroid directly. Later turns can be away but the more you can get to actually touch the toroid core, the better the response, for a joule thief secondary.

Does that mean it was shorted?
