Where the OVERUNITY using INDUCTION COILS comes from (eg Joule Thief)

Thanks Carroll. Probably I'm only 34. Lol

They are older than me also.  And I am slightly more than double your age.  They are an interesting device though.  And were still being used up until the switching power supplies came into common usage.  The interesting thing about them is the output voltage stayed the same over a wide range of loads and a wide range of input voltages.  A lot of the ones I saw used in industry had an output voltage of 120 volts.  But the input could be anywhere from 90 volts to 135 volts or so and the output stayed the same as long as you didn't overload the output.

About that Carroll, I've read that they work by saturating the core near the secondary, thanks to the capacitor loaded winding. In a normal transformer, when we talk about saturation it's due to the primary, correct?

Sorry for the absence. I needed some time for local projects. Got a lot done so I feel better.




So for the arguments that a JT isn't a bifilar coil. Mheh.. Look at the the opposing winds. Just because it is connected differently doesn't mean that it won't have the same interposing wind rules that apply. An EMF moving in such a coil of one half of the winding will indeed reduce the cemf, in fact it should even increase in voltage because of the opposite polarity being shunted in between the primary winding. The core is to purge the magnetic field from the process which enhances the magnification. At least until saturation of the core then a leak happens.


I'm working on a very special coil setup that uses iron gardening wire with a bifilar primary and over wrapped solenoid secondaries. Two halves of the toroid iron wire circle will be used. A single channel, so two bifilar coils in series for the emitter coils wrapped on the iron wire toroid. This should allow disruptive discharges from a cap to an antenna as a virtual ground. The larger the antenna the more it can handle voltage before it breaks down the air around it and suck in free plasma from all around the antenna. The plasma should move to the antenna because the voltage acts like a vacuum to it. This should allow me to magnify the bifilar emf blasts as it (plasma) back feeds to the bifilar emitters. The secondaries should translate the emf blasts into AC which can be diode rectified into DC for storage and reuse.


Once the primary tank is filled it should run very happy till it wears out.


The secondaries I believe need to be of heavy solid copper wire and the secondaries will get very hot because of the emf blasts they are receiving. Later on cooling should be applied to the secondaries to keep them in operating condition. If large enough copper water pipe can be used and water pumped through the pipes to cool them.


My initial tests will be done as I build a grow light Led system. That will be my first test and will most likely have a battery involved to get the process started and keep the battery charged as it runs. Unfortunately you need a kick off run initially to get the process started. After the first run it should back flow into the battery and charge it up. I might need some circuitry to handle the charge back and cut off the power to the battery when it is charged enough. I should be able to use a current sensing resistor and sub circuit to handle that.


The small unit is already built and I should be starting my trials on the device. Digital meter and scope waiting to have some fun. As long as I start out slowly I should be alright. Give it slight power in the beginning and try to ramp up the power storage as I develop some graphene batteries I watched being built. This will make an excellent battery charger for those kinds of batteries since they are most capacitor like.


Also I am gonna be trying a few other things out with this setup including an interior rotor with self terminated coils and the effects of that related to Tesla's other machine I am going to be making.


I used some networking wire that is solid core but seems to be made of tin but coated with copper as the bifilar emitters. The one problem there is that it is fairly light gauge. I'll show pictures later.


If you look at a JT circuit there is indeed an interposing winding. That is just about the length of similarities to the bifilar wind or simply method. This interposing winding style separates the primary coil from itself and that kinda gets rid of most of the cemf. In fact I am thinking that this system could get gains via that fact, seeing that the negative is interposed to the positive wiring of the primary coil. Kind of like a speed boost only. So the current stays the same but the intensity or voltage level rise from the speed boost through the coil. With self inductance being somewhat removed from a coil where is this coil gaining the voltage then? The only other value you can change is the voltage really and that should equate to speed of the charges moving through the coil.


Tesla's other device uses the same premise. It's a motor generator with gen exciter built in. A magneto. All of that is turned via the motor or prime mover. The generator section has the same setup I am about to start testing with the Led driver. The emitter coils are bifilar going to an antenna. It is being fed impulses from a capacitor disruptive discharge circuit. That circuit is fed via the magneto exciter. The emitters are discharged into a heavy copper coil in the rotor which should generate huge currents in those coils. This will be split between the prime mover and load circuits and the rest if any is used to charge a battery or bank of batteries.


This device was patented by Tesla and only shown in vague details. The other patents Tesla released were used in that device. This is why we never really found any thing special about the older device. Every aspect was looked into by Tesla and I will be showing each patent and where it applies in the new device. This includes a magnetic Prime mover controller (motor controller), disruptive discharge circuits and many many other devices used to enhance the devices output. He was very smart about what he did. He put it all out there in the public's eye and no one really caught on until now.


For the meantime I will be experimenting withe this new disruptive discharge transformer setup. This is the heart of the generator portion of the device I mentioned above. Every aspect of the devices patent has been shown in greater detail in a bunch of individual patents with the devices patent being a way to put them all together.


Not all patents by Tesla were used. only a select group of them. I will try to post them all for everyone to see.

A JT coil need not be "interposed". It is effectively one continuous winding in the same direction, with a "tap" at some place along the winding. This can be a center tap or it can be closer to one end or the other. The winding can be on a toroidal core, a solenoidal core, or no core at all. Even a "tesla bifilar pancake" winding can be used, with the center tap being the series connection between the inner end of one winding and the outer end of the other winding. Solenoidal or toroidal JT coils can be overwrapped, interposed, or can be in two separate sections on a rod or toroid core.

Note where the "dots" are on the JT diagram. This dot indicates the "start" of a winding. The JT schematic typically draws the coil as a transformer, but if you consider the dots, you will see that it is actually one continuous winding all in the same direction, effectively "center tapped" or tapped closer to one end, to give a turns ratio other than 1:1 between the two sections.

Everyone who has built JTs knows that if it does not oscillate at first, you simply reverse the connections of one of the "windings", (actually one of the sections). This results in the total coil being connected just as I said: as one continuous winding in the same direction with a tap somewhere along the length. Once this fact is realized, JT builders will never again have to "guess" how the windings are to be connected for proper operation the first time, every time.
