To anybody remotely interested,
I am a master of physics graduating 2000 A.D at the University of Kent at Canterbury. While I was doing an experiment in my granpas garage, to see if I could use the piezo electric effect to seperate the charge carriers in a semiconductor, I stumbled across something interesting. The idea I had failed to show any meaningful results (possibly due to poor equipment). However I left one of the piezo electric quartz blocks in my grandpas vice under pressure. My volt meter was registering 10 mV +/- 3, across the x cut faces. This voltage across the surfaces of the crystal will not deplete. I had already done this experiment at Graham Deblins precission engineers, Margate Kent England. I offered them this idea for free. Unfortunately Graham Deblins precission engineers has gone bankrupt and no longer exists. The experiment consists of short circuiting the x cut faces, so the voltage across the crystal becomes 0 volts. Then without changing the pressure the crystal is under, removing the short circuit. to my suprise the voltage across the x cut faces returned to 10mV +/- 3. As a matter of fact I can safely say that unless my voltmeter is giving me seriously eronious readings that you can short circuit the x cut faces an infinite number of times with the voltage returning on removal of the short circuit. If my voltmeter is not lying to me, and the experiment can be scaled up ( which it probably can't seeing as perpetual motion machines can't work via the laws of physics), this could provide a new means of generating vast quantitees of electricity. Forgive me if this is old news, or horribly flawed, I just can't find any information about it anywhere.
Yours faithfully

i am interested in your article could you develop something that will work to produce electricity from the mechanics of a car moving.

I have developed covert car trackers which fit underneath a car but i am looking at a way to produce electricty to keep the units alive
any suggestion will help

I have a B.S. in Physics, and I know that the DC resistance of quartz is extremely high, thus, short circuiting the crystal faces will drive the voltage to zero while inside the crystal the electric field will still be at a level determined by the piezoelectric effect of the applied pressure. The only way to extract any useful amount of energy from a quartz crystal is as an AC waveform, preferably at the series resonance frequency of the crystal so that the crystal impedance will be low and an appreciable current will flow. This would require application of pressure waves at the resonant frequency of your quartz or other piezoelectric transducer, which would probably be in the ultrasonic range. Useful power cannot be derived by short circuiting what is in effect a static charge on a small capacitor.

This is very interesting. Actually the best way to create pressure IMO would be using weight rather than a vice. would it therefore be possible to get piezo electricity from the base of large granite blocks like the ones used in Stonehenge? If so would it not be possible to create a lighting system possibly using a type of florescent bulb which could glow constantly. Also since this system effectively transduces energy from the surrounding environment. Would there be an advantage in making structures of a specific size to act rather like a dipole antenna is constructed to a specific electrical length in order to receive or transmit specific radio frequencies? Well just some thoughts :)

A) Was the vice insulated from the crystal?
and B) what is the input resistance of the voltmeter used to measure the voltage?
If the answer to A is 'no' then you could have had had a useful current flowing thru the vice (assuming it is a metal vice, but see the proviso re. corrosion below) and the beginnings of something useful... if the answer to A is 'yes', then the input resistance of the voltmeter is important... many digital voltmeters have an input resistance in the order of Giga-Ohms, and so, as Bill from Germany implies, the quartz crystal's capacitance - a few picofarads - will take forever to discharge thru'' your voltmeter, especially as the dc resistance of quartz is very high, too. On the other hand, if you were measuring the V with an old moving coil meter, then you have something. But do check that your vice, stored in a damp garage possibly, isn't creating a small voltage through corrosion processes (electrochemistry) which is leaking into your experiment through using, i.e. paper or card as the buffer between your crystal and the faces of the vice. Surprising how easy it is to accidentally create a battery, as old Landrover owners will know as they watch their pride and joy spring leaks in the doors... Hope this helps. from Petchy, Cornwall.

To Artberry - I just remembered - this is called the triboelectric effect. Also.. bash bits of quartz together in the dark and you get light directly - it's called triboluminescence. I have tried it with the white 'spar' rocks we get here ion Cornwall and it works. On a safety point - do wear googles when you try it as bits fly off the quartz into your eyes, which kind of spoils the point of the experiment. Don't think bashing rocks a very efficient way of producing light, however if you highly compressed the quartz at its acoustic resonant frequency that would be interesting...

To Tintinrob: Yes I've seen the effect you can get from bashing or rubbing bits of quartz together. I heard about that on Coast to Coast and tried it with some small quartz pebbles I happened to have in a small table top ornamental fountain. It works quite well and works even better under water which is amazing.

I've tried putting these pebbles in a g-clamp and applying pressure, then attaching wires from either side to a small electric motor. I didn't get any sort of motion unfortunately. But I would imagine there's probably some voltage being given off but probably not enough to run a motor. But neither do I have any means of measuring it.

But the Piezo electric effect does seem interesting. Obviously if you're dealing with mountains of granite (which of course is mostly quartz) and seismic pressures in order of billions of tones there must be a considerable amount of piezo-electric energy in the earth itself which is basically a product of gravity creating pressure and friction.

Of course there's also that recent conference given by a former NASA employee and Richard Hoagland reporting NASA have found and covered up huge glass like structures on the moon. I wonder therefore if these structures are some form of piezo electrical generator. Well there's less gravity on the Moon so it probably wouldn't work quite so well as on Earth, but obviously they could be made much larger.

OTOH though I suppose one could also use the optical qualities of glass to collect and transmit the heat and light of the sun. So there could be some logical reason why a civilisation would construct enormous glass structures on the Moon.

So the fact that such structures appear to exist, and have been reported by reasonably credible people is amazing, because it is exactly what one would expect to find in terms of archaeological remains of lunar colonisation or even evidence of current ET habitation of the Moon.

Mine is not so much a response but an observation. I often notice that when lighters using piezo crystals are pressed and released that you get two sparks which is just you noticed with your crystal in the garage

Sometimes I think I'm the only (fully accredited?)mad scientist out there. I am really excited to find people talking about generating electricity this way. I have patented a device operating on similar principles to the discussion here. It would be great to have some folks such as in this discussion be party to and beneficiaries of its development. If you want to talk, please E Mail me at [email protected] My name is Peter.

Free energy with no moving parts. The device needs to be tuned to the note of "a". To do this use the 5/3 ratio for it's size such as 15"x9"x9" or 5'x3'x3' or any other 5/3 ratio size. The device needs to be zapped with a neon sign transformer to magnetize it. Do not put it on the ground and keep it shorted out when not in use. The device works on the principle of piezoelectricity and compression. When silicon dioxide is compressed the oxygen atoms will become deficient in electrons and thus all free electrons will fall into it. You may have to soak the stones in water before assembly so they absorb oxygen. Beware of lightning bolts. Do not touch the device, it is a capacitor and can discharge and kill you. USE EXTREME CAUTION YOU ARE MESSING WITH HIGH VOLTAGE> you are building it at your own risk and I will assume no responsibility for your injury or death. BE CAREFUL!
You are building a musical instrument and it has to be in tune so it vibrates to the musical note of "a". There are no moving parts so it will never break down.
You can build it with most metals, however gold is preferred if you want it to last because gold will never corrode from oxygen. The stones you use must have a high quartz content or it will not work. If you make it powerful enough you will stop time around you, however.. your mind will not remember or comprehend any time travel experience that you encounter because no time will have passed so there is nothing to remember.

I found this that use quartz granit produse large
amount of elecric voltage

Tasos, this is an interesting concept. Could you elaborate more? Did I understand that the granite is compressed by metal and that prior to operation one must magnetize the entire device? So what part does the magnetization play? does it separate the charges or are they symmetrically distributed? Why tuned to the "a" note? Essentially, the device obtains a net positive charge but once enough electrons are absorbed wont the device reach an equilibrium? How does this have any effect on time?

The two blocks inside have holes drilled through them and the positive electrode touches the inside of the hole as well as the bottom inside metal of the box. The 2 inside blocks have only one hole drilled through each. The transducer has 2 holes drilled in it but the negative electrode does not enter the box..it connects to the outside top metal of the box.
The box itself is tuned to 5/3 ratio... the stones are not tuned, but have to fit snug inside the box because you are compressing the stones inside using the Bielfeld Brown effect. The device needs to be zapped with a neon sign transformer (high voltage) to magnetize it.
A smaller device will need an antenna connected to the outside to pick up the free negative electrons all around us... a larger device will not need an antenna.
Red granite is used because of it's high quartz content and elasticity. Red rose granite was used in the original design 5000 years ago also known as the Ark of the covenant. The device really works.. when built properly in tune all it takes is the "a" note of a musical instrument to start it...and you will need to short it out to stop it. You CAN EVEN Start it with your own voice if you are capable of signing the note of "A". It has to be in tune so it vibrates or it will not work..you only need to tune the box... this is a tuned capacitor and it needs to vibrate to work. It beats just like a heart but much faster than you can see or hear.

That is all i have
and a blur picture of the device

I have just one question concerning the crystal, do you know if the crystal was generating any current?

gentleman...maybe it isn't publicly acceptable to discuss such things, as it likely draws criticism from skeptics, however, everything you're mentioning about needing, and i quote:

"This would require application of pressure waves at the resonant frequency of your quartz or other piezoelectric transducer, which would probably be in the ultrasonic range. Useful power cannot be derived by short circuiting what is in effect a static charge on a small capacitor. "

Would a hydraulic ram pulse generator work for this application? Say, if you made a large building out of stone with quartz structure in it, and made a kind of mortar/paste that was also comprised of crystalline material, to paste between the stones...say...

a giant pyramid? With a massive resonance chamber inside?

I know this is years old and likely none of you will respond to this, but I figured mentioning the giza pyramids would help. Also noteworthy is that pyramid sites all over the world were constructed out of stone that has crystalline structures in it, and are also built so that the rise and fall of the sun places the maximum amount of light at the very top of the pyramids.

They were doing something big and it would seem that your research and experiments are providing clues to what has already been done once, thousands of years ago.

also noteworthy: gold/silver alloy (80/20) parabolic mirrors used to cut quartz granite. The metal reflects sunlight, and where the reflection focal point is, it is reflecting with ultrasonic frequencies. At that focal point, place a precious stone and focus the light out of the precious stone, i have no idea what will happen, but id imagine something fascinating. Say, a ruby. I digress, but it's all related.

Mr D.R.Gillan (Mphys), i am currently doing a research project involving piezoelectric materials and their applications. I currently am experimenting with a certain generator ( PIEZOELECTRIC TRANSDUCER 200 KHz 43x10mm DISC) and can only attain voltage through applying pressure. once. I am now wondering how it is that your quartz crystals can can constantly produce current.

About how much pressure is usually applied to produce a voltage? I am interested in using this as a power production method underwater, as pressures about 30 bars. Is this too much? Too little?

To Will Wright...I like your ideas about the pyramids on the Giza plateau being used as piezioelectric generator...I seem to remember reading that huge sheets of mica were removed from south american pyramids by local people..located in between the top levels of structures. Isn't mica a non-conductive material? I may have read this in Grahm Hancocks writings, I'm not sure at the moment. If these structures were just buildings what would the point of putting insulation between building blocks?
