42.7khz

[oicu812]

does anyone know how to produce a 42.7 khz vibration cheaply? its the natural frequency of water. if we could get a dry cell to vibrate at that frequency I would think production would increase dramaticly.

[H2OPWR]

Although I have not seen any difference in MMW production with higher frequency's I would love to know how to pulse the elctricity at that high of frequency. I smoke my fet's at anything above 20khz. I have ruined 10 fet's trying. It does not seem to matter the quality. The higher the frequency the hotter they get until you get the magic smoke.

[oicu812]

actually I was talking about a physical vibration not an electrical pulse.

How about generating an AC current at that frequency as the AC cycle time, but place a diode in the current delivery line to stop the current reversing on that part of the cycle?

Outlet AC cycle's at 60hz in the US, you just need to find some equipment to do a different cycle frequency. AC generator of some kind?

oicu,

A Function Generator is a piece of electronic test equipment that provides a variable frequency. You can buy them pretty cheaply.

thanks fisher. this costs less

stu.. I copied your amobia cell design. works great, thanks man

basicly what i'm thinking here is if I can get the water moleculs to vibrate at their natural frequency of 42.7 khz they will disassociate into h and o much easier. brute force is great but i'ld like to try to do it more efficiant . to over simplify it , its kinda like trying to light a log on fire with a match. but if you took that same log and sliced it into a million micro thin sheets with a tiny gap Between them that match would light that log in seconds.

[fisher]

Yea, sounds strange to me too. Where are you, if in Dallas, I can lend you a function gen for testing purposes.

How do you know the "natural frequency of water"? What does that even mean? If soldiers march a cross a bridge at its resonant frequency, they can start the bridge viberating at that frequency... but water???

A quartz crystal, will physically viberate at some frequency, frequency adjustable by the thickness of the crystal. Search for a 42.7KHz crystal and put it in water. But again, I would think that IF water would viberate, the frequency would depend on the receptacle, depth, temperature... IF

09/10/89 - This is an excerpt from a document graciously provided by Dan A. Davidson from his book "A Breakthrough to New Free Energy Sources". The entire document is listed at KeelyNet as DANART1.TXT should you wish to study it. Dan can be contacted at Dan Davidson. The file has been excerpted because of a recent post indicating a cheaper way to carry out the experiment. That post is at the end of this file. Note: This file is being posted PURELY for information. Any attempt at duplication could be HIGHLY DANGEROUS. If you choose to experiment with water dissociation as described in this file, you take full responsibility for any damages or personal injury which might result from your actions.
Verification of Frequency to produce
Etheric Force from Water - 12/20/97
A recent (1965) possible verification of the frequency Keely used to dissociate water into etheric force was related to me by a scientist when we were discussing certain aspects of free energy. He wishes to remain anonymous for obvious reasons, but his name is on file. I have no other verification of this experiment, however I believe it merits telling. The scientist, I shall call him Dr. X, was doing experiments with ultrasonic sound in a column of water. The object of the experiments was to devise a means of separating various densities of materials by injecting them into a column of water which was subjected to an ultrasonic standing wave vibration. The experimental setup is sketched in Figure 3-3 (for BBS considerations a description follows). A Barium Titanate ultrasonic transducer was fixed to the bottom of a quartz tube which was closed at the bottom and open at the top. Pure water was poured into the tube and the water column was "tuned" so that a standing wave was produced at 40,000 CPS (cycles per second). The transducer was powered by a 700 Watt power amplifier which was driven by an ultrasonic frequency generator. Because of the large amount of power put into the column of water a certain amount of evaporation took place at a constant rate when the transducer was energized. Therefore, to maintain a standing wave in the water column a feedback device caused the frequency to be raised as the water evaporated and the temperature changed. As a test, Dr. X decided to run through the experiment with only water in the tube to insure that a standing wave was maintained as the water evaporated and the frequency rose higher and higher. When the experiment was started everything worked beautifully. Dr. X took periodic readings of his instrumentation and was assured that the standing wave was being maintained. Suddenly, with no warning whatever the water disappeared from the open quartz tube. He looked up thinking to see the water splashed on the ceiling when to his amazement a clean hole went right through the ceiling. The hole was the same size as the inside of the quartz tube. Further investigation showed the hole continued on through the roof also! Dr. X checked his notebook and found the last frequency entry to be 41,300 CPS. It was shortly after this that the water disappeared. Because of the time interval between the last reading and the disappearing water, the frequency sent to the transducer was higher than the last reading and Dr. X said it could well have been very close to 42,800 CPS, the Keely dissociation frequency. (11) This obviously dangerous event caused Dr. X to dismantle the equipment and try some other approach to his problem. This experiment points the way to the use of our modern technology in conjunction with Keely's laws of dissociation to change matter into energy without the use of radioactive materials or extremely expensive atomic accelerators.
The following was from a post received on 12/20/97. The names have been removed for privacy. "A friend of mine, suggested modifying an ultrasonic humidifier (replacing the frequency tuning resistor with a variable resistor) such that it could be adjusted to operate at the 42k frequency requisite for the separation of H2O into it's constituent parts (I haven't tried it). The power level of the humidifier may be inadaquate for the job, however."
An interesting idea since piezo transducers (any transducer) can be tuned to any frequency, but has the greatest energy transfer at its resonant frequency. So you could very well use an off the shelf piezo rated at 32khz (its natural resonant frequency) and simply power it at 42.8khz. It would require the establishment and maintenance of a standing wave to properly disrupt the molecular bonds. Since the container used by Dr. X was open ended, what happens if you carry out this experiment in a sealed container, say in a piston chamber? Maybe a single cylinder lawnmower or motorcycle engine? Or would it be more efficient to contain the explosive energy in a pressure tank which would then run the engine, much like the BOESE liquid nitrogen engine or the Airmotor powered automobile. In Keely's experiments with water dissocation in the late 1800's, on many occasions he had explosions that burst iron tubes and in one case blew out the side of his lab. He wound up in the hospital with broken ribs and major bruises. The iron pipes had a needle size hole through 1" and 2" thick iron, which were burst like balloons. Measurements of the force produced from water dissociation based on his experiments quoted "3 drops of water, instantaneously dissociated (in a spherical chamber) to produce 29,000 pounds per square inch".
Recently we learned that the Water Disrupting Spark Plug promoted around 1994 by Stan Meyers was in fact suggested to him by Dale Pond at a conference in Switzerland back in 1989. The idea was you should be able to use Keely's 42.8khz emitted from a spark plug to instantly dissociate the water molecule to hydrogen and oxygen which would then be exploded to drive the piston. Meyer took this idea, claimed it as his own and never credited Dale with the idea. He cannot patent it because it was disclosed in a public place in the presence of witnesses. Needless to say, like all of Meyer's other claims, nothing has come of it. This is a further indication of how certain people try to capitalize on others' ideas and are not to be trusted...hide your wallets. Check out Dale's SVPVril Website. If you choose to carry out experiments in this area, please share your findings, whether failures or successes with us here at KeelyNet. Thanks!

BoyntonStu

there are alot of things that I don't understand that can be measured. I'm not the most educated man in the world, but I do know that if I don't understand something, I'll at least be able to find the answer by asking people that know, or researching it enough for myself to make an educated decision.

I feel that it's unfair for you to make a statement such as this as it assumes that if people don't understand something that it must not be fact based. How does this relate to learning?? if our children don't understand somehting, do we assume then that they CAN'T understand it?? If i had waited a day or two to research etheric force, then read for another day or two to see (for myself) if it's possible to dissociate water molecules and produce etheric force, THEN post the link, would you have reacted differently??

I think not. My belief is that by stumbling across these pages that refer to Stanley Meyer's work (while looking for something entirely different) and posting the link here for all to see, that doesn't in any way warrant the insult you have presented here.

I had assumed that those that DO understand the 'words' could pore over the material that I provided and make a sensible determination. if you choose to call it BS that's fine and good, but now it's my turn to ask for your proof. You like to ask for proof when people post ideas, or claims. I agree that this keeps things fact based. We don't need a bunch of false claims. I applaud you and others for this. HOWEVER when you play the BS card, you don't support your decision here with anything other than sarcasm. so could you please explain to those of us that AREN'T well educated of many means WHY water CAN'T be 'dissociated into etheric force' or is it just a belief of yours???

Dr. Andrija Puharich's vibratory method of breakin
Taken from KeelyNet BBS (214) 324-3501 - Sponsored by Vangard Sciences - PO BOX 1031 - Mesquite, TX 75150

Vibrations that Split Molecules
Produce Energy

Seawater - or even dirty rainwater - could be transmuted into fuel through a new technique serendipitously discovered by a researcher in medical electronics.

Dr. Andrija Puharich has found a way to split water molecules by tuning in on the vibrations of their atoms and breaking the molecules into hydrogen, which could become fuel, and oxygen.

Alternating-current impulses augment naturally occurring vibrations in the H2O molecules. By boosting the vibrations out of control, Puharich makes the molecules fly apart into the component atoms.

He likens the water-splitting effect to the way soldiers marching in step across a bridge risk damaging the structure by making it vibrate at a critical, stress-producing rate.

Electrolysis by simple direct current would create hydrogen and oxygen with a net energy efficiency of only 54 percent, according to Puharich, a Virginia-based inventor. But he says his alternating-current system reaches better than 90 per cent efficiency.

A former physician, Puharich discovered the water-splitting technique a dozen years ago but has only recently presented his findings publicly.

Originally, he was investigating the DISRUPTIVE EFFECT of electrical resonances on blood clots and noticed a peculiar thing: in dilute blood, a SPECIFIC FREQUENCY made bubbles appear in the liquid.

Lab analysis showed that the bubbles were composed of oxygen and hydrogen.

A barrel-shaped cavity contains the water in Puharich's recently refined system. He introduces alternating current at A KEY FREQUENCY of 600 cycles per second.

The cavity resonates with the impulses in somewhat the same way the body of a violin resonates with the sound of one string, ADDING HIGHER AND LOWER HARMONICS TO THE PRINCIPAL TONE.

The additional harmonics, Puharich says, cause the proton in the hydrogen atom TO ROTATE, further forcing the hydrogen to split from the oxygen.

Puharich suggests that the splitting energy could be provided by solar or wind generators. The hydrogen could then be stored and used conveniently in fuel cells or hydrogen-powered cars.

------------------------------------------------------------------

Vangard notes...

This paper is quite astounding in that it correlates with Keelys' claim that water can be progressively dissociated at 620, 630 and 12,000 cycles per second. These are on the molecular, atomic and etheric levels respectively.

It is interesting that the etheric level of 12,000 / 20 = 600 (Puharich's frequency) found by original experimentation. This 600 cps frequency is therefore a harmonic of the 12,000 cps frequency which Puharich discovered.

Keely also claims that the disruption of water occurs at 42,800 cycles per second.

The direct quote from the book "Keely and His Discoveries" by Bloomfield Moore, published in 1893 ;

"The orders of intensification for accelerating dissociation would not be understood by any explanations that could be made, if unaccompanied by the demonstrations witnessed by the late Professor Leidy, Dr. Brinton, and others.

"When the ether flows from a tube, its negative centre represents molecular sub-division carrying interstitially (or between its molecules) the lowest order of liberated ozone.

"This is the first order of ozone and its wonderfully refreshing and vitalizing to those who breathe it.

"The second order, or atomic separation, releases a much higher grade of ozone; in fact, too pure for inhalation, is the one that has been (though attended withe much danger to the operator) utilized by Keely in his carbon register to produce the circuit of high vibration that breaks up the molecular magnetism which is recognized as cohesion.

"The acceleration of these orders is governed by the introductory impulse on a certain combination of vibratory chords, arranged for this purpose in the instrument, with which Keely dissociates the elements of water, and which he calls a Liberator.

"In molecular dissociation one fork of 620 is used, setting the chords on the first octave.

"In atomic separation two forks, one of 620 and one of 630 per second; setting the chords on the second octave.

"In the etheric three forks; one of 620, one of 630, and one of 12,000, setting the chords on the third octave.

As a matter of further clarification, Keely states that you cannot DIRECTLY dissociate a single level of aggregation due to the shell structure of matter.

In other words, if you wish to dissociate the Atomic level, you must first dissociate the molecular to be able to get to the atomic. That follows also if you wish to dissociate the etheric, you must disrupt the molecular AND the atomic, THEN the etheric.

Keely refers to this technique as progressive dissociation.

In 1988, we had Andrija Puharich in Dallas for about 4 days as a joint speaker for Vangard Sciences and MUFON Metroplex. We spent many hours with Andrija and discussed a wide variety of subjects.

At that time, I asked him about this experiment and he said the original research was done in the late 50's, early 60's by him in a dual attempt. One was to selectively remove gases from the blood and the other to dissolve clots.

Andrija had not heard of Keely or his work with dissociation or disruption of matter with acoustic frequencies. He was quite interested that the work had been done almost 100 years ago and wanted to know more about Keely.

Dr. Puharich has dropped out of sight over the last few years, so we have lost contact with him. He was at that time (1988) very concerned about the ecology and was working on some type of retreat for future hard times.

They were re-building an old hydro-electric power system fed by a small lake on the land they had in Virginia. Puharich at that time was living on land donated by R. J. Reynolds.

We heard recently that Reynolds was attempting to get the land back. Since we have not seen or heard from Andrija in about 2 years, we don't know what is going on with him.

We hope this information is of use in your researches.

I with Stu on this one... seems like BS.

I'm not really trying to debate whether water can be converted to electromagnetic force or not, basically what I was upset about is that Stu had insulted me (and others) without pointing out references. That was my point...

now onto the etheric force debate...

I don't see why water couldnt be dissociated this way.. seems as though there are several references to similarly conducted experiments...

In my opinion, anything that has vibrations induced 'into' or 'onto' it has a 'natural' resonant frequency... (remember, my opinion, I don't have facts to back it up, yet, but i'll look around)

If water has a natural resonant frequency, then why COULDN'T it produce etheric force?? water 'distorts' things when you look through it, it deflects bullets when they travel through it, sound waves travel very very far through it (as well as sonar, similar to submarine use, and dolphin communication)

Logic tells me that it COULD be possible... although to what extent and how powerful??

(again, these are just my opinions without reading all the material that's presented here)

[daddymikey1975]

Keely's Perpetual Motion Machine, was apparently a hoax..

pages 78, 79, and on for a few... seems as though he scammed his investors for 26 years... BUT that just means that keely's work was a hoax, it does not mean that "etheric force" doesn't exist.


Thomas Edison's Etheric Force
http://www.edison.me.uk/thomasedison'sethericforce.htm

and for a very informative read on what experiments Edison was doing when he stumbled across it:

page 251, 252, 253.


Seems as if Etheric Force (as found by edison) is akin to radio frequency 'waves'..

knowing this, I think we can deduce that water COULD be made to produce 'etheric force' by applying the same to it.

although what's unclear, is how it's gonig to apply to HHO... ??

[oicu812]

I figure there's no sence chasing Etheric Force. it seams way out of reach. its seams more realistic to me to use vibration or sound waves to try and come as close as posible to waters natural frequency. every element has a natural frequency,their moleculs are in motion unless there at absoulute zero on the kelven scale.if we can use the vibration of the right frequency to loosen the moleculure structure of h2o it certainly would increase the efficiantcy of electrolysis . function generators aren't that expensive and i'm even leaning towards using an ultasonic humidifier with a drycell . they're pretty cheap to come by, less than $50 bucks at target. function generators can even be software that runs on your home computer that use the audio output jacks to a transducer.I don't dream of over unity , hell i'ld be happy with 70% effeciancy.

[coffeeachiever]

Tesla did some experiments with resonance. He reported nearly collapsing his lab with a unit smaller than a breadbox. I'd bet my bottom dollar that Tesla's documents were not a hoax.
Everything has an energy, therefore must have a resonant frequency. I've believed this since I first started researching HHO. If I'm wrong then over time I will prove myself wrong. But in the quest for overunity I don't think we should leave any stone unturned.
I think H2OPWR has the right approach- test everything and take nothing for granted. His philosophy on this, and it's mine too, is how previously overlooked things became world changing discoveries.
I for one believe resonant frequencies may play a large roll in future technology and I plan to explore them.

[Q-Hack!]

I guess the biggest question on my mind is this: If you can, in fact, produce HHO using the above mentioned resonance freq. and it gets the reaction described in the article. Then what do you do with that amount of HHO? Storing HHO in small quantities is hazardous at best, let alone large quantities. That is one of the nice things about HHO on demand... You use what you generate right away.

I suppose you could reduce the water amount. However, a sustainable rate enough to fully run your engine on HHO only, you are still only in the range of a few drops of water per second. I am not sure you could feasibly produce a standing wave in a few drops of water easily. Caveat to the above is that I know almost nothing about fluid dynamics.

[oicu812]

again, not to repeat myself i'm talking about using resonance frequency together with electrolysis to increase production.

[daddymikey1975]

again, not to repeat myself i'm talking about using resonance frequency together with electrolysis to increase production.

I believe this is where the rabbit hole starts as well.

It DOES seem as if Stanley Meyers was experimenting with similar ideals...

I started another thread about this, but no one replied.. i'm not sure how many looked at the material, but Meyers has some info on resonance and such... here's the link to the thread that has the link to the info that I found (it pertains to this as well, but i didn't want to hijack this thread when it was started)

link: http://hhoforums.com/showthread.php?t=2026

if you scroll down just a bit, you'll see his control circuit for dissociation of water molecules (which is basically resonating them, either for etheric force or just to increase production, I'm not quite certain as some of it is over my head, but it's something i found nonetheless lol)

Hope I don't get slammed by Stu for posting something that's over my head :eek:


I hope this helps

Im not sure how you'd apply it to a dry cell either, but Meyers was using a bath cell with the tubing, right? We could experiment with switch plate cover cells for now. I've got about thirty of them in my shop.

thanks mike, i'm gonna stop by radio shack and see if I can pick one up. I found function generator software that runs with windows. my thoughts are to attach the transducer to the outside of the drycell plates and let her rip. if you guys don't hear from me it means I blew myself up.

this might work.. attaching it to the outside of the cell plates... when you go to radio shack to get one, get one with the highest frequency reproduction available... I doubt you'll find one that'll produce up to 50kHz but if you can find one that'll do 30-40k that'll get you close...

http://www.radioshack.com/product/index.jsp?productId=2062402

only up to 3kHz (pooor..)

OR... how about a cheap a$$ tweeter...

http://www.radioshack.com/product/index.jsp?productId=2925219

this one is 'web only' but I bet you could find a pair at your local audio shop or out of a crappy pair of bookshelf speakers for dirt cheap. (I have a crappy pair of bookshelf speakers I would dismantle for you and ship the tweeters if you need me to)

I hope this helps.

One thing I think you are missing, is power. The article regarding the guy that blew a hole in his roof, mentioned that his generator was putting out 700 watts of power. A function generator may put out 1/100th of that, maybe. Now you need an amplifier. A sound amplifier does not amplify 42800 hertz. It stops at around 20000 hertz, the upper limit of human hearing. So you need an amplifer that amplifies ultrasonic frequencies.

Could you, crudely, put the input signal into a 70 odd amp rated MOSFET and use it as a crude amplifier? You would just need to adjust the load that the MOSFET is switching to the required current? Is there a MOSFET that won't tear up at those kind of frequencies?

[Painless]

This amplifier design states that it can produce 500W at 3.5 Mhz?

You will have to look at the specs of the MOSFET that you want to use... With MOSFETs the frequency is usually determined by an external capacitor. However the internal switch time to turn on and off does create a theoretical maximum frequency. Look for specs that say something like t-on and t-off. This is the time delay for turning the MOSFET on and off. (Sometimes it will be expressed as Rise Time and Fall Time.) If you add these two times together you will get the built in delay of the MOSFET. If you take the inverse of that you will get the theoretical maximum frequency.

example: http://www.necel.com/nesdis/image/D16259EJ2V0DS00.pdf

Turn-on time delay is 23ns
Turn-off time delay is 110ns

23ns + 110ns = 133ns

1 / 133ns = 0.0075 or 7.5 Ghz

Understand that this is only a theoretical maximum frequency... I highly doubt any semiconductor will run very long at its theoretical maximum for very long if at all. However, for the frequency range you are wanting it would be ok.

Also understand that you would be feeding a square wave to the speaker in question. Not really a big deal but it might be kind of hard on it over time.

The source I found about vibrating wat at its natural frequency is http://www.kodasplace.com/more/watermotors.html

I am curious about this because I know with regular electrolysis the power source tends to burn up and become useless, I don't know if this would have the same problem but according to this site the vibration creates a lot more hho then typical electrolysis.
