Single circuits generate nuclear reactions

[Feynman]

Those were just a couple of the toroidal transformers we were looking at, I hadn't checked the sizing yet. Some of them may be the wrong shape or size, I just figured I'd post the links to get started on materials suppliers.  There are probably better toroids and better vendors.  I think in seriousness we may need to wind our own toroids because the output amperage can be quite high.  Unclefester was using that allelectronics toroid, but he ran into problems because the wire gauge could not handle the amperage. It may be best to simply get a toroid of an appropriate size and wind it yourself with wire of a sufficient gauge.   

There is alot of information that is missing that will need to be learned by experiments, such as how the output voltage is affected by the number of windings, how the Boron-12 pulse shape is affected by the input voltage, etc.  There are alot of variables to consider, and I think alot of this will only be sorted out by experiments.

Here DC means "average", not "direct current"

No, wrong. DC is a universal term now. Any guy dealing with Fourier transforms and spectrum power plots assumes w=0 to be DC, because Fourier is often used to analyze time series, e.g. in DSP.

@aleks
As I've said, I am tired of discussing this, as it is now at a level of semantics.  If you wish to continue, please pm me, so we do not clutter up the thread any more than we already have.

Let's keep discussion relevant to the topic, as this thread was started by Juan.  A good starting point would be to continue expanding the list of materials suppliers for people interested in replicating these circuits. I will suggest one path forward may be IGBTs, which are usually available on E-bay for a good discount.

IGBTs are basically high-amperage transistors which can be used to discharge large amounts of current simply by the presence of a drive signal at the Gate.  Some of these IGBTs support up to 1600V at 300A.  I do not think this amount of energy will be required to get a self-powering device, but it may be helpful to have some extra capacity.  IGBTs at this voltage/amperage are available for less than $4 apiece.

Another good call. I was looking at Reply # 22 of this thread that has a picture (supposedly) of Juan's device. His transformers do not look 'hand wound'. Look like 'off the shelf' items. They also look like they have about 1/4 inch diameter opening. The wiring size seems pretty small. A lot like the Alltronics ones. I am wondering if perhaps he is using smaller 'off the shelf' transformers and cascading them. Seems a reasonable solution instead of hand winding a large one.

The picture you are talking about is one I received of Juan's 60kW device.  I think you are referring to the collector toroids, if you mean the ten copper wound donut shaped objects.  If this is what you mean I think they only have a primary winding, no secondary.  (just one continuous piece of wire)

I thought they were custom hand-wound or machine-wound.  Looking back at the picture, it's also possible they are off-the-shelf.  I have not looked for them yet, but maybe we should start seeing if we can find an off-the-shelf part!  That would save alot of trouble.   I think you are right in saying the toroid windings to not appear very heavy, but it's hard to tell.   I can't even determine for sure whether they are enameled or insulated.   Also , it's possible the visible copper are just the "outer windings" of a thicker gauge inner collector. So all this is sort of up in the air I think, probably until we resolve some questions with experiments. I agree that it's doubtful all ten toroids were hand-wound, but it's possible they were custom fabricated using a winding machine.
