measurement of spark and arc

Dear Wicaksono,

Thanks for asking. I'm in the process of constructing test circuit #123. This evening I need to dig through the snow and ice at the barns and see if I have two more .05 uF 5000 WVDC capacitors to finish off a five stage pulse forming network. Right now I'm attempting to measure the dynamic resistance of a spark/arc under conditions similiar to what has been doisclosed from the Gray history. This parameter is important because it determines the design of the method used to provide the current pulses in the Gray technology.

Hello Mr. McKay, are you still using NST to make the spark and arc ? What is the schematic diagram look like ?

Experiment #123 Schematic and Power Supply

Hello Mr. McKay, are you still using NST to make the spark and arc ? What is the schematic diagram look like ?

Dear Wicaksono,

For a power supply I'm using a 250 Watt 500 - 5000 VDC tube regulated FLuke Model 503 rack mounted power supply. Its big and bulky, but the price was right.

The individual unit power supplies in the EMA4 engine were 30 to 50 watt choppers, so I have more than enough power to duplicate the operation of one of these power supplies. If I need more than this I'm not on the right track.

The schematic is that of the 1986 CEST with some modifications. The storage capacitor is replaced with a five stage type "E" Pulse forming Network composed of 0.05 uF capacitors and 4.4 uH inductors (using #14 AWG wire). The charicteristic resistance calculates out to 9.43 Ohms. The SPICE IV simulation shows a 4.6 uS pulse of 270 Amps delivered to the HV electrode.

The thyratron is being replaced with distributed diodes in the PFN. It is my speculation that the thyratron was being used as a HV high current diode in this application. I know that the Bedini Field Notes show a reversed solid state diode (from 1973). According to John he said he was not sure what the ture polarity was. His mentor Ron Cole kept changing the polarity in an attempt to figure out the system's operation. What John provided was the way they ended up on the last draft of the noites that John Copied.

I plan to look at single pulses. I'm using a 100A motor contactor to take the place of the commutator switch. The load resistor is the combination of a 500 Amp meter shunt (about .0001 Ohm) and a variable 50 Watt 15 Ohm resistor.

The CEST is 1-1/8" copper water pipe 8" long with a 1/4" HV electrode. This is much smaller that what John disclosed in his field notes, however this seems to be more along the lines of the CSET used in the EMA6 and in the patent documents. About all I can do here is see if any classical charge can be collected into a low loss capacitor using a lead-acid battery as a vitural ground (a Tesla technique)

I'm using a second 50 Amp contactor to charge the PFN prior to test firing. I'm placing a 20 H reactor (wasted spark ignition coil secondary) in series with the PFN so that the capacitors don't appear to be a short circuit to the power supply.

Data will be primarly collected from the 500 amp meter shunt resistor. The PIV of my diodes is limited to 3200 VDC, so I don't plan to go beyond 3000 volts for this series of tests. As it is the first diode has to pass 138 Amps of current while the others need only pass 58 Amps. If the response time of the diodes is quick enough I shouldn't get any reverse flow with this setup.

The purpose of this test is to establish just what the dynamic arc/spark resistance is with various 1/4" electrodes. I suspect that there was a viable reason why silver/silver was used.

The PFN will have to be reconfigured to match the effective aprk/arc resistance at the time of cut-off in order to provide the fastest fall time from maximum current. The simulation for this circuit shows it to be around 100 Amps/ uS. Who knows if this window of operation is what is needed to stimulate the dielectric? But at least it is a place to start.

Once I start taking data I shall draft the actual test circuit. You know how these things go. There is always last minute changes to the circuit when you have to use what is at hand.

Meyer & Delrin

Now Lamare says that the Stan Myer system used Delrin in an oscillator circuit that has some similarities to the Gray power supply circuit in that it also has a common mode reactor (the Floating Flux Field).

Hi Mark,

I posted this way back:



Virtually every reference with Meyer and Delrin is simply using
the Delrin as an encasement to isolate the tubes from the
other tube sets. Otherwise, they're all short circuited to each
other. Without something like this, the tube sets are very
"leaky" and is hard to get the voltage up but with this type of
insulating case, the voltage can climb much higher as the idea
is to turn this into a "water capacitor." So instead of Delrin,
I was going to coat the outer tube in Plastidip. But later,
I found some pvc tube that my outer tubes slipped in perfectly
but I wasn't able to finish those experiments. Even with the pvc,
the ends of the tubes are exposed and are still shorted to
each other through the water so the ends still should have
Super Corona Dope or Plastidip.

Anyway, that's not really related to the Cole-Gray concepts -
just saw the Meyer reference to Delrin and thought I'd bring up
the Corona Dope and Plastidip - because those actually would
serve the purpose of what Meyer was using the Delrin for.

I don't think Meyer was actually looking for any special properties
of the Delrin other than a good insulator for the outer tube.

Hi Mark,

Dear Aaron,

Interesting drawing, thanks for reposting it.

Wouldn't it be crual irony if the sucess of Mr. Myer's systems were the result of a process he wasn't even aware of. If his chamber actually did excite the Delrin to produce an anomalous energy how would he have known? Stranger things have happened in history. If he continued using the Delrin liner he would have continued to get good results.

Who knows? There is a good chance that Gray and company stumbled across the OU aspects of an excited dielectric while in the pursuit of an industrial pulse motor.

high voltage rack mounted power supply

Dear Wicaksono,

For a power supply I'm using a 250 Watt 500 - 5000 VDC tube regulated FLuke Model 503 rack mounted power supply. Its big and bulky, but the price was right.

Hey this is a great item Mr. McKay, is this power suppy has programmable input to regulate voltage output or current output ?

Dear Wicaksono,

The Fluke 503 is from the 50's so there is no programmable computer circuits associalted with it. The voltage is set from four (4) rotary switches and one potentiometer. Even so the output shown on the analog meter is 5% lower than what the switches show.

I got it at the WSU (Washington State University) mounthly auction outlet for about $20.00.

Internally it is composed of vaccum tube diodes and triodes (but still works). It has a front end voltage doubler that boosts the initial internal voltage to 10 KV. Then a triode regulates the current to maintian the output voltage setting.

I hope to transition from single pulse operation to continuous operation in a few weeks. Right now it taks 40 mS to charge the PFN. At that rate I can only generate 24 pulses per second (pps).

IF the EMA6 turned at 1700 rpm that would be 28 pps, so I'm in the ball park.

vacuum tube power supply !?

From 1950's ? Vacuum tube is definitely a diehard technology, still works well after 60 years. Instead of GPIB bus input, does it have any analog input to modulate the output ?. I hope they sell it complete with the manual, the electronic manuals from early years usually contains complete schematic diagram of the internal circuits.

No such luck. Auction sales are "As Is Where Is". I was fortunate to have all the tubes in it and that it functions. Manuals??? Are you kidding. Nothing at a recycling/surplus auction is complete. This stuff is one steap away from the scrap metal bin. In fact most of my compeatings bids are from metal recyclers and eBay resellers.

An analog input? That would make it a high voltage amplifier of some sort but the response time is much to slow to bother with.

When you are self funded, like most of us are, you have to take what you can get and do your best with it.

There are many things in this world that money will not buy, but modern calibrated test instruments are not among them.

Gray Motor For Sale (again)

Dear E.V. Gray Technology Researchers,

If you have lots of liquid $$$ and want a real collectors item to put in your living room check out this notice from the Sterling site:

Classifieds:Original EV Gray Motor Available for Right Lab - PESWiki

Apparently Al Francouer is willing to part with one of his Gray Motors, most likley the "Black" version, for an acceptable bid. The intent is to get money to fund his continuing reverse engineering research efforts.

The last two motors that John Riley sold are rumored to have gone for between $25,000and $42,000 each. That is certainly outside of my funding capacity. With that kind of money I could buy some pulse current transformers that wouldn't saturate at 50 Amps.

It will be interesting to see what kind of offers are tendered.

The Gray motor that Al is offering is the "Gold" Motor with the cart and some new replacement parts (capacitors). He doesn't plan to sell the "Black" or "White" Motors.

Charged Particles

Does anyone have any knowledge of Geiger counter readings taken around the known Gray equipment?

The story of the confiscation and destruction of the equipment seems a bit overboard for some spurious emissions. They would, however, be perfectly understandable in the 70's if some kind of radioactive material were detected.

Go back and look at Tesla's quotes about radium. Why would it be important to him that radium could be produced for $1 a pound?

Keep in mind that this was in the 30's before nuclear detonations, radioactive materials were not well understood, and probably not regulated by the government at all at that time.

What would a disruptive discharge inside a Gray tube filled with radon gas produce?

Today there are self powered light bulbs filled with tritium gas that light up a phosphor coating inside the tube with no electrical supply. They are similar to the emergency exit signs in building stairwells that require no power source.

If I remember correctly, back in the 50's and 60's the markings on a watch dial and hands were made with radium so they would glow in the dark.

Dear tx1138,

All the relatives and ex-employees that I had the opportunity to speak with never once mentoined radioactive substances or insturmentation to measure any sort of classical ionizing radiation.

There were two confiscation events. The first in 1973 was for alledged business fruad and had nothing to do with energy emmissions of any sort.

The second was in 1977. It is believed that this was done by the FCC for RF emissions. If you don't believe this sort of thing can't happen - then you have no viable field experiance in this area. The FCC in this country has the undisputed power of Natzi strom troopers. Operating a high power (say 20 KW) wide spectrum EMI source will (and did) get an immediate response.

There are a number of OU devices that are based upon radioactive substances. Most notably the Hubbard Device. No doubt there are several methods to harness the latent energy in unstable isotopes, but it doesn't appear (at the moment) that this approach was used by the Gray team.

Tube Burst Technology

Hello all,

I'd like to ask if anyone could explain how much energy is being produced from mixing the positive potential of the running battery with positive potential of a high voltage capacitive discharge in the primary of a pickup transformer by comparison with pulsing it with just the battery by itself.

Would a pair of miniature enclosed spark gaps work for the first gap to 12V and the second gap to (-)Ground?

When resonance is acheived by the primary burst rate in the transformer, how then will this change the output?
