input:  ed gray not working    (without any " " )

Why on earth would I do that?

so you show devices that NOT working
as devices that WORKING  (?)

I do not wish to be obtuse here, but ... what?

You must shown first. before you will
buy the "papers" at 70$ that are "mysteriosly"

Are you trying to sell something?

[pese]

No , i have nothing to offer in this area.
An frind have buy the original schematics at 75$,
aft i sayd him , not to do.
I have seen the papers. Its scrap , no value
Sorry, i have also not an idea for working devices

Pese.

From that last post I can see your english is not so good.  I now see why I didn't understand your previous post to me.

The EVGray circuit

In theory, the EVGray circuit is quite simple (I will point out the practical difficulties in a moment.)  Jerry Volland has posted a number of circuits.  You will note he is using a defibrillator inductor and mentions a "current limiting action" caused by this inductor.

An inductor is simply a coil.  It can have an open air core or an iron core, but either way it is nothing more than a coil of conductor wire.  Also called an toroidal coil inductor, it is used in classical EM circuits to filter out certain frequencies.  But for the EVGray circuit, its purpose is more fundamental and intimate than generally understood.  That purpose was to filter (or "choke") out current.

When E.V. Gray built his circuit, he patented it calling it a circuit to run an inductive load.  E.V. Gray was either purposivly obtuse or didn't understand the theory behind what he had built and how it worked.  Perhaps it was a little of both.  In any event, the EVGray circuit was used to run Gray's inductive motor ("EVGray motor") which reportedly generated 80 horsepower.  One does not need to be a P.Eng to look at that motor and realize it was unnecessarily over-designed.  But one thing that it did do was filter out current.  According to the patent, it was this current, this "back emf" that was diverted and sent to the charging battery during the operation of the motor.  Whether one believes this or not is irrelevant.  The many, many coils in the circuit \ motor filtered out current.

The "secret" which isn't a secret. 

One must pulse high voltage across a spark gap filtering out the current.  On each pulse, the high voltage "arc" will cause a discharge of radiant energy perpendicular to the direction of electrical flow.  The radiant energy is picked up by a copper grid which by virtue of the nature of copper, converts it to standard EM electricity which can then be used for powering a load.

That's it.

Today there are many people who understand the theory.  Jerry is one of them, though he hasn't to my knowledge built a full EVGray circuit.  He is testing the creation of the non-classical event he described above as a "slow, fizzeling squirt".  He has elsewhere described it in such a manner to make me believe he has generated radiant energy - albeit for a short period of time.

Tom Beardon is another one.  Peter Lindemann is another one.  John Bedini is another one.  Tesla was certainly one.  There are many, many others some living, some dead.

A prime source for learning how to create that non-classical "radiant energy" is John Bedini and his SSG circuit.  John has successfully shown the existance of "radiant energy spike" on a scope (his "h" wave.)  His circuit is based on generating Electric Potential while filtering out the current.  Like EVGray, it is done on a pulsed basis.  His measurement of the effect of the radiant energy (other than the strong spike shown on his scope) is by the cycling of charging and discharging of lead acid batteries.  He has a yahoo group for this purpose.

So again, the key in the EVGray circuit is to generate a high voltage potential while filtering or choking out the current which potential is then arced across a gap.

So what's are engineering challenges?  There are a number of then, some of which EVGray never completely solved.  What follows are just a few to give you a taste of the nature of the challenges facing the researcher and the bench technician.

1.  The pulses must be of a high frequency, high voltage and low amperage.

1a) High Frequency

Regarding the frequency, Tesla mentions many millions per second.  We are in the gigahertz range here.  Obtaining this level of frequency at a high voltage has a whole set of engineering issues that must be overcome, not the least of which is the natural tendancy of the inductor coils used to filter out amperage to be relatively "slow."  Mechanical oscillators or voltage choppers won't do the job.  Solidstate is probably the way to go, though there are some vacuum tubes that will achieve it.  One cannot start with a relatively low level of frequency and then "scale up."  Unless a certain frequency is used,  the radiant energy event doesn't occur.  I have a paper on a Sanyo 2SK3748 MOSFET transister array that switched 3k volts at frequencies and pulse widths in the ns range.

1b) High Voltage

While generating high voltage is merely a matter of transforming an existing voltage, high voltage carries with it its own set of challenges and issues.  The first is to protect oneself from a potential lethal shock.  I use a high voltage mat, high voltage gloves and high voltage rubber boots.  Moreover I use a welder's mask when generating the arc to protect my eyes.  The second is to protect one's equipment.  Scopes don't come cheap.  I have a number of varying high voltage probes I use.  The third is to protect one's shop.  The importance of fuses and breakers cannot be overemphased.  Purchasing a fire extinguisher is an absolute necessity.

1c)  Low amperage.

Ensuring a negligible level of amperage (current) is necessary to ensure the appearance of the radiant energy event. The inductor coil is probably the way to go and it was certainly the way Gray acheived this.  Because of the high frequency of the pulses and the relative slowness of the inductor coils to charge and discharge, it is likely necessary to have more than one inductor coil and some sort of switching means to alternate between the coils.  As soon as one speaks of "switching" when high voltages are used, there are potential arcing problems in the switches if mechanical switches (relays) are used.  If solid state, the high voltage pulses generate heat which has its own filtering effect and eventual failure of the solid state switch is always a concern.

2.  Transformers can only transform a/c electricity.

The EVGray technology is based on running the whole system from 12 or 24 volt batteries.  Therefore the voltage must be "stepped up".  This requires transformers.  Since the battery produces dc, some sort of system must be used to "chop" the dc (turn it on, off, on, off etc.) so that the transformer can transform the electrical voltage upwards.  Once the voltage is at the desired level, the ac electricity must be rectified back to dc prior to producing the arc.  As should be readily apparent, the higher the voltage, the greater the effort to protect the bridge rectifier diodes.  This requires "balancing" the individual diodes with resisters and capacitors.  Each of these components have their own capacitances, inductances, heat generation and failure potential.

After obtaining his reported 3,000 volts, EVGray collected the electricity in capacitors prior to discharge across the gap.  He charged up two high capacitance capacitors (to voltages that were presumably much higher than 3,000 volts) and then only partially discharged each capacitor at each pulse into the circuit.  This obviously required a switching system between the transformer and capacitors (to switch from one capacitor to the other) and then beween each capacitors and the spark \ arc gap to switch between the discharged capacitor and the charged one.  As mentioned above, switching has its own set of problems in high voltage, high frequency applications.

3.  The arc must be distinct and sharp - a "cracking" arc according to Tesla.

An electric arc is relatively easy to generate.  Any welder can do it and does it by hand and "feel".  Of course the arc welder permits high current and it is the current that generates the arc.  In our case, we are trying to generate an arc with negligible current at a high voltage.  Otherwise we would be simply building an arc welder.  So an arc without current is the goal.  This can be done even though it is contrary to standard EM theory, but it requires a strong push of voltage that is stopped after the arc and before the amperage flow (using Dirac particles?)  Whatever the actual physics involved, it happens.  Look at Jerry's posts above.

So we generate a high voltage, negligible current arc which is stopped, started, stopped, started i.e. "pulsed" as distinct, sharp and cracking discharges.  This isn't so easy.  This is an effect which is a factor of the distance between the electrodes, the temperature of the air, the voltage (amplitude on the scope), and duration (pulse width on the scope) of the electricity.  In order to "tune" the circuit, each of these components must be tunable.  Remember to use an appropriate probe if you are going to measure the pulse on the scope.

3a) Starting the arc.

To generate the high frequency mentioned by Tesla requires timing controls which could be anything from an array of HV transistors (MOSFETs) to a 555 on the low voltage side of the circuit or combination thereof.  To achieve various pulse frequencies, Gray reportedly used mercury based thiristor tubes.  Presumably these were almost as difficult to obtain in the 1970s as they are today.  Because they are mercury based, they are actually illegal where I live.  Gray also tried transisters in "darlington arrays" but reportedly burned them out over and over again.  Today we have access to high voltage and robust transisters he didn't have access to, but they are expensive.

3b) Stopping the arc.

The high frequency pulsing electrical circuit not only requires a "starting" of the arc, but a "stopping" of the arc.  The arc must be completely dissipated prior to the next cycle.

To obtain the necessary "stoppage," Tesla reportedly used magnets and hot air.  It is not clear just how he did this.  The pictures of the arc gap and magnets show up in some of his patents.  This technology, or something similar, must be developed further.  Even though transisters can be used, and are typically very quick at their "stoppage", the rest of the circuit will not give up its voltage, amperage, or magnetism due to any circuit's natural inductance and capacitance.

4.  Residual Issues.

There are a number of residual issues the EVGray researcher must be aware of.  I can only mention a few.

4a) EM interference.

It should be noted the generation of a high voltage, high frequency arc will generate a lot of EM "noise" that will be picked up by anyone using sensitive electronic equipment close by.  So if you don't want to interfere with your neighbor's radio, T.V., ham radio, the local communications of a military base, police station or airport, you must build a "faraday cage".  I work in my garage in a large city.  This is obviously a major concern of mine.  My "faraday cage" is the body of two microwave ovens which will be situated over the spark gap.

4b) Electrodes.

EVGray reportedly used silver tipped electrodes.  This certainly would facilitate the arc across the gap.  It would also cut down on the inevitable wear on the electrodes.  To "silver tip" electrodes requires a finese and knowledge of metalurgy, not to mention a small smeltering capability.

4c) Carbon resister.

The low voltage "side" of the circuit meets the high voltage "side" of the circuit at the arc gap.  According to the patent, on the low voltage side there is a resister.  No specifications are given for this resister.  However, it is this resister is reportedly a "carbon" based resister.  The EVGray researcher would do well to note this.  There is in the scientific literature scores of articles on carbide and carbon negative resistance being observed when a charge is placed across the material.  This resister is within the "tube" used to pick up the radiant energy.  It likely has an effect on the production of the radiant energy event.

4d) One way electrical flow.

The circuit must not permit a reverse flow or the radiant energy event will not occur.  The resister mentioned above may help to prevent this, but the judicious use of diodes and full bridge rectifier will also help.  In addition to the four diodes in the full bridge rectifier, EVGray's patent 4,595,975 shows two more diodes.

4e) Choking the amperage

By the judicious use of toriodal inductor coils, the amperage must be choked off as much as it is possible for the radiant energy event to occur.  During the pulsing cycle, the coils will have to be discharged and the resulting amperage diverted away from the circuit either to earth ground or a resister system.  Whether or not this can be done as fast as the gigahertz frequency mentioned by Tesla is doubtful.  Thus multiple toriodal inductor coils and a switching system may have to be used.  I am planning to try two very large air-core toriodal inductor coils for this purpose as has been seen in pictures of EVGray's system.

Conclusion

The above are some of the issues I've met in my research and testing.  I hope this post is not too long or too tedious to be helpful. 

Sources

There are many sources for the EVGray technology.  Primarily, the researcher will examine his American patents 3,890,548 (June 17, 1975) 4,595,975 (June 17, 1986) and 4,661,747 (April 28, 1987).  He also has a British patent but as I recall, it was even less helpful than his American ones.

Mr. RB Hackenberger, Engineer of Evgray Enterprises Inc. wrote a short "Technical Discussion" regarding the technology that is, in my view, interesting but hides as much as it discloses.

There are a number of media articles each of which give clues to the technology.  See the "L.A. Free Press" (Dec 28,1973), "Newsreal" (circa 1973), "Probe" (circa 1976), "Progress Bulletin" (July 7, 1975) and "National Tattler" (July 1, 1973, March 16, 1975).

There is one particular book on the EVGray circuit, Dr. Lindemann's book "The Free Energy Secrets of
Cold Electricity" which provides a valuable comparison between EVGray's circuit and Tesla's comparable technology.

Other works include Mr. Beardon's works available at http://www.cheniere.org, John Bedini's works available at http://www.icehouse.net/john34/, anything published by Tesla - his patents, books, compilations, and articles.  There are documentaries about Tesla that are also helpful.  See also works by Dr. Konstantin Meyl, John J. O'Neill 1944, Thomas Commerford Martin 1894, Thomas Valone Ed. of Harnessing the wheelwork of nature 2002, John T. Ratzlaff , Electrical Experimenter Magazine 1919, and the Tesla notes published by the Nikola Tesla Museum.  Though it has been criticised by some, I also recommend the book "Secrets of Cold War Technology: Project HAARP and Beyond" by Gerry Vassilatos, 1996, especially chapter 1.

Everything mentioned above gives hints and clues as to the actual workings of the EVGray circuit and the nature of radiant energy.  It has taken me several years to accumulate and digest this material and collect the components required.  I would like to see many, many people working on this circuit.  Get off grid before there is no grid left.

Hi there fletchdaf,
                          IMHO, There is one observation that I would like to make regarding your interpretation of the high frequency pulses. Tesla's originating pulses were low frequency. He also, spent a lot of time and thought on arresting the current through the coils - hence, he discovered the magic timing cut off of .062microsecs for the originating pulse as the voltage leading the current due to the "skin effect". The high frequency was supplied by his capacitors. Otherwise, an excellent post.

Regards

Ed Gray, never have find and TRIODE-TUBE than can wort with the announced
(i belive it was around 200Volts and 100 Amps)

Idont know Triodes like this, only gassfilled Thyratrons than can only SWITCH (like an SCR)

i think: To use Vakuum-Tubes - is an wrong way.
