Single circuits generate nuclear reactions

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.

Good Morning Uncle Fester,

Thanks for the information. Your numbers and mine are VERY close.

I find that I have a real problem here with my carbon rod out of a D Cell battery.  Using a Fluke 77 III Multimeter, that can resolve .1 ohm resistance,  the measured resistance of the rod is less than  0.1 Ohm, or beyond/lower than the capability of the meter to accurately measure it. 

With resistance that low, it is almost impossible to deliver the majority of the energy to the rod as the total resistance of the loop including wiring, connections, power supply impedance and contacts/or switch around the rod must be at least a magnitude of 10 times less or >.01 ohms TOTAL and this is most certainly the problem I have with starting a reaction.  As I said, almost impossible but not if tenacity is employed.  Clip leads, # 12 wire will NOT work here. 

It is also very clear that the pictorial in the original article would never work, too much resistance in the driving circuit.Not enough energy delivered to the carbon unless the carbon rod was a very high resistance piece of material!  If my assumptions are correct, a working unit will look most certainly different than depicted! Perhaps the orginal article and pictorial was just a theroitical visulation of what is required to initiate the reaction.  A real working unit will have to be built like a tank with very heavy low resistance buss bars, high pressure connections, VERY low on resistance of solid state switches, VERY low impedance Cap. bank!,  The possibility of MANY SS switches on a common buss, fired at same time seem a necessity.  More basic R&D needed here. 

The very fact that 110J is needed in the rod is interesting.  To inject 108 J into the 1.8 ohm rod requires a discharge of 60 amps into the rod to produce 108 volts across the carbon!  Tedious scope work showed this is difficult to obtain just mucking around!. Any voltage across the carbon of less than 108 volts would not work with this sample of rod and this is in a perfect world of zero losses in the buss bars and switches and infinitely low power supply internal resistance.  It is interesting that the Joules, resistance all line up here, theoritically correct but not a practical depection of total values circuit wise needed. It would appear that there is manipulation of numbers based on theory and not real world actual working conditions......Again, lots of R&D needed.

In some previous post, I remember a location given to obtain a specified rod.  I'll look it up and order the correct material.  In the mean time I'll try other carbon sources for messing around purposes.  Anyone have a 2 to 10 ohm rod???

Will be back when I have the correct rod and figure out how to build a device in my small lab that meets the conditions needed to work or if further discussion is needed. 

Again, none of the above is negative or implies that the device will not work.  Just my observations and thoughts on the fly as I see it on what will be required to make it work!

Wrong carbon, way way way too low resistance. Bigger wire would be nice too, I use #6 with solid copper eyelets on the ends, about 4mm thick. Should handle 100 amp pulses easily. I also use a special electrolytic. It's made by UBE (Rifa), ultra low impedance. If you discharge this capacitor (2200uF) with a screw driver it will rattle the whole shop unlike all the other electrolytics that only slowly discharge or make a small popping sound under the same conditions, this one is made for pulsed applications. It will dump the entire charge as fast as you want it to (within reason). Power supplies must be isolated, I fried a processor and other stuff until I isolated everything, and I still need MOV's for snubbing before I will fire this again.

Hi Uncle Fester,

Thanks for the heads up on the resistance of the rod.  I need to find some Photo Flash Caps in the 360V range and 2200 uf or where I can parallel them to get the output current/low impedance needed. Do you have the part # for that RIFA cap?  I also have to find the right kind of rod...Haven't found the post yet.....Anybody have that link?


I suspect your Cap. pretty well mucks up the blade on the screwdriver with a "hard" discharge!!!!!   Hope everyone watches their voltage drops across all connections/junctions ect. in this device.  @ 60-100 amps, they add up fast and power delivered to rod goes away!

Rifa caps:

PEH200VU433AQ is 400VDC @ 3300uF

http://www.evoxrifa.com/n_america/electrolytic_cap_cat.htm

Place I purchased them:

http://search.ebay.com/_W0QQfgtpZ1QQfrppZ25QQsassZlisaQ5fctrsurplusQQssPageNameZSTRKQ3aMEFSQ3aMESOI

These guys give good service and have plenty of 1200V @ 300A IGBT dual modules (bricks) and other goodies. You can Also find the Rifa caps on ebay through other sellers as well.

Carbon rods 1/4" (6mm):

Larger Carbon:

P.S. You can easily smoke a small screwdriver with these caps = ) Sounds like a shotgun blast going off if you are crazy enough to do it. Although that's why my handle is UncleFester = )

Hi Uncle Fester!

Are you a take off on Uncle Fester the "Mad" scientists of the "Adams Family" AKA Tad?

To get real now. I had given up on this technology a couple days ago as impractical and washed my hands in disgust until I understood the resistance problem (saw the light!) in a carbon rod from a D cell battery. As I absolutely refuse to accept failure if there is "One chance in hell". (I've been jousting with windmills for most of my life)....assuming the theory is correct, I will give it a "best shot" and see what happens.....Less than $100 invested to have basic correct materials on hand ( spent many times that on Bedini motors) and all the other parts are here from other experiments.

Pure carbon rods have been ordered. Ordered the 61-15 Carbon Rods, Grade 1 Spec-Pure, 1/8" x 12" (3 x 304mm)  I did get the 1/8" instead of the 1/4 for resistance reasons but can bundle if needed.  All I want to see is a burst of radiation which I understand can last as long as 20 sec. after a pulse.  Heck, I would take 0.1 second long as a "BIG" event.   A nice 4200uF @500 VDC RIFA cap (  PEH169ZY442GM ) with very low ESR found and purchased on Ebay using "buy it now"..Have power supply to do slow rep. rate single pulse test.  IGBT's/opto's or HD Rly contact already on hand.........All will take about a week to get here.

Any hints on how to terminate to carbon rods?

Thanks for the help!
