Single circuits generate nuclear reactions

[UncleFester]

Hi Uncle Fester,

Several folk have been watching this thread and there is serious testing going on off this list.  No sense talking about it unless absolutely positive results.  I personally would not mind a hand drawn schematic from you, saves time and effort and gets the point across very fast.  My friends and I have all the equipment to build/test this device. 

From what I see so far, the engineering mountains to overcome are pulse current into and then current out of the device.  I so far have EMR pulse problems that really mucks with solid state instruments.  Shorts in the Toroid due to flash over when rod fires, HV supply Caps. that break down in a rapid fire pulse mode. High voltage/current IGBT's that roll over and die on command.   It's not as easy as it would first appear to be. 

Can you use a high current bidirectional sine wave through the rod/reactor or do you find that there is a need for a rapid rise time mono polarity pulse in the rod for maximum output?

You're right, it's not as easy as it appears to be. Isolate your switching electronics. I use separate power supplies for both the logic and the gate firing circuits (TC4422CAT) and another HV supply for charging main capacitor. Everything is opto-isolated from the switching logic as well. Large transistors are needed for the discharge and everything is earth-grounded. I believe we still need a fast single polarity pulse from the capacitor bank. I doubt a sine wave will work.

@UncleFester,
we are still waiting for a video from your new camera...
Did you already get your new camera ?
Many thanks.

Yes, but there has not been much to film yet = ) I am still trying to get a full charge across the carbon. Once I get that done I will make some video. I am not sure where to upload it to, but I will try and play with it a little. Been very busy working on this circuit.

Hi Uncle Fester,

Thank you for your assessment of my question and your straight forward answer.  It never did make sense that a sine wave could drive this device into excess output.  As you suggested, a chopped sine wave might work but it would take a heck of a circuit to drive essentially a 0 ohm load.

I suspect the most misunderstood aspect of the whole device is the current density within the carbon element that is required to initiate a reaction.  The 110J is a nice number to point at but unless we know the amount of carbon in the loop, the minimum rise time requirement of the pulse, the duration of the pulse and on and and on,  It is a huge question mark as to how to procede.  By that, I mean, is that 110J pulse based on a cube of 1 sq. centimeter of carbon or would it be 110J /gram of carbon?  It is very ambiguous to use that particular number without supporting information.  Is it a 300V 1 ms pulse or a 300V 10 ms pulse, all dependent on size of cap, etc. Then too what is the repetition rate required to maintain a energy flow?    IF a large rod is used, the amount of energy require to see this low level reaction would be immense as the energy flowing through the lattice of carbon would be spread out over a large area.

If you do the math on a carbon rod, the voltage drop across it with varying voltages from a cap. bank, and the required 110J or 110 watts of peak pulse dissipation, it becomes very quickly obvious that unless you have a power supply the size of a old VW, your rod must by design be very small with some measurable resistance..Then heat becomes a beast here, In fact, I wonder if it not part of the equation?.........

So far after starting off with a lot of excitement, I have simplified my circuit until I am now working with the most simple of devices.  Using a cap of 20uf and 0 to 4000VDC, in the 0-160J range, dumped via a single pulse from a heavy duty relay contact into a D cell carbon rod has resulted in NO detectable radiation above background pulses on my 1960's style radiation counter.

I am down to next trying to dump this into a very small carbon rod (#2 lead pencil) and essentially "glow" it or possibly vaporize it and/or initiate a continuous spark between two small rods, similar to a carbon arc lamp but with magnetic bias and hopefully see the background radiation rise after a pulse.  Without seeing the radiation rise, all the rest of the circuitry is an exercise in futility.  If I can get the radiation, the rest is duck soup for me.

As per Juan:

Carbon rod is 6mm and 60mm long. It is 1.8Ohms total. 110Joules works out of the following formula he gave. You can and should calculate it yourself as well. With every step up in voltage, the capacitance requirement drops by a factor of four. 110 Joules is discharged across the rod EVERY PULSE.

Case   Capacity (micro farad)         Voltage ( Volts )
1        1521200                                12
2         380300                                 24
3          87620                                  50
4          21920                                 100
5           9740                                  150
6           2280                                  311
7           760                                   540

For the case 5 is like connect a condensers bank to an electrical net of 110 VAC, the case 6 is for a net of 220 VAC, and the case 7 for the voltage between the lines or phases in a triphase system of 220 VAC for phase and 380 VAC between the lines.

So if you want to use smaller transistors to switch the bank, then use higher voltages. If you want 60Hz AC power then discharge 60 times per second across the rod. The transformer will act as though it is connected to standard mains and the power out is a clean sine wave.
