G'Day all,

@Koen:  I have read about those glowing rocks before. I think they were discovered in central Europe.
I agree that some form of Beta emission could be responsible for their characteristics. Yes, Cesium may be hard to get but Americum is plentiful (smoke detectors). I like your idea of using high temperature ceramics, thats definately an area I would like to explore.


As far as the "cookie" goes it is still holding at .4V but this voltage tends to fluctuate. This is because
the mix is very hydroscopic. Atmospheric moisture affects the output so that alone infers a galvanic reaction.

The next one I built (2 days ago) I moved my attention to the electrodes. Probably the most important part of the whole thing.

This is my theory:  Working on the assumption that the finely crushed silicates bring into play the Casimir effect and polarization during crystalization aligns the charges, there is still a randomness of charge throughout the mix.
These charges need to be rectified. I believe this done using specialy prepared electrodes.

To test this I prepared a stip of mild steel (the stuff they tie round packing cases) and copper plated it in copper sulphate.  The copper coated strip was then heated to cherry red with a blow lamp.
The idea being to create a coating of copper oxide. Copper oxide is a p-type semiconductor.

I also added to the mix a small amout of colloidal chromium . This was added as a tracer as any net charge would make the bright yellow Cr move one way or the other.

The mix was hardened in the usual way and a polarizing voltage of 12v was applied. +Ve to the copper coated strip. The chromium migrated to this post.

The cell started off with a terminal voltage of 1.2V but slowly decayed when  a 10kohm resistor was placed across it. This was not to be unexpected.  After about 30 minutes the voltage on the terminals reversed polarity. That was what I was hoping for.  The + post became negative. With no load across it I get 150 mV. With the 10k ohm it holds at 37 mV. Sure, like before , not a great deal of power but
It looks like using the electrode as a rectifier may be the way to go.

Well thats the state of play at the moment.

Koen have you ever heard of any metal becoming radioactive in the discharge of a Tesla coil ?

Happy hunting

Catch you later

Ian

Ian,

indeed Americium or similar substances used in smoke detectors may be used... Although many smoke detectors nowadays are "optical" and don't actually use any radioactive materials at all any more. And of course it will still only be an atomic battery of some type, so the output will drop dramatically as the atoms decay; for longer periods it would be best to use elements with a long halflife, and those are less easy to obtain again. But still, if one can get beta-emitting material cheaply, it might still be a good source of power... Quick grab from my memory banks, if I recall common beta emitters are strontium, mostly the Sr90 isotope, with a halflife of about 30 years (all other Sr isotopes range from a halflife of a couple of days to a few milliseconds and are thus not very usefull in a battery), cobalt 60 with a halflife of something like 5 years (but! this decays into nickel60 emitting 1 beta particle and 2 gamma photons, and the energy contained in the gamma photons is quite a bit more than that of the beta electron, so not extremely healthy to say the least), iodine 129 and 131 (both used in medicine) with halflives of 7 years and 8 days respectively, and tritium with a halflife of 12 years (but this is actually superheavy hydrogen and decays into helium3, which is of course a gas and will probably decrease functionality of any battery).
Of course other types of radiation emission can be used to generate electrical output as well, if we use the radiation to "knock loose" some of the electrons in the surrounding material, which would be quite similar to photovoltaic cells that use normal light to do the same. This however needs quite some shielding material to make sure the radiation doesn't damage living organisms around it, which would probably make such a battery too heavy for practical use, unless of course we build a miniature atomic battery, but then the output would be relatively small again.

As for the electrodes, yes, it seems to me that you may want to rectify the output. Now it doesn't really sound like your "cookie" is producing a clear wave output, but the output does seem to fluctuate somewhat...
Taking into account that tourmaline contains quite some SiO2 itself, and that SiO2 and other silicates are known to have oscillation frequencies directly related to their crystal structure and composition, one might reason that every piece of quartz inside the "cookie" is a tiny oscillating unit, and the "cookie" thus contains multiple tiny oscillators.
Since oscillators just "shuttle" charges "back and forth" and don't care about the direction in which they do so, the "push and pull" on these charges by the oscillator should average out to about zero. The pyroelectric qualities of the tourmaline scraps account for the clear temperature dependant output, but the direction in which the charges are finally "pushed" depends mostly on the relative p-n effect of regions inside the "cookie", I think.
So you could attach simple electrodes to the top and bottom of your "cookie", and attach a rectifying diode bridge to the electrodes, so that a capacitor connected to the diode bridge receives only positive charge on one plate and only negative on the other, then measure the voltage gain in the capacitor... (You know how such a rectifying diode bridge is made, right? To each elecrode, you attach two wires via diodes, one diode allowing the charge to flow toward the electrode, one diode allowing the charge to flow away from the electrode; then you connect both "outgoing" diodes to one terminal of the capacitor, and you connect both "ingoing" diodes to the other terminal. Voila, rectification of waves/fluctuations.)
But you can of course also turn the electrodes themselves into relatively positive and negative layers, indeed by using copper oxide as a p-layer, and so forth. I am not certain if this will rectify all of the fluctuations, but at least if will create a forward bias as long as the output voltage has the right polarisation.
Another possibility is to make the "cookie" in such a way that the relative p- and n- layers are contained within the "cookie" itself.
Obviously, these possibilities range top-down from easiest to hardest to actually implement.
Theoretically the application of hV during the cooling and solidifying stages should generate a p-n bias inside the material already, and up to a point one would expect some relative p-n shifting within the material, causing a slight internal pn rectification already...

A possible problem in ceramics is that, in certain ceramic materials, ions are still free (to a degree) to move through the material, and will do so in reaction to electrostatic and electrochemically induced forces. This may cause a ceramic to seemingly produce output during a certain period, then lose all output after that, because all movable ions have moved and the material is now electrically stable. In certain ceramics heat-driven cycles can occur, which move certain ions up and down a path, which can generate a direct electrical output. This is clearly an ongoing heat-driven electrochemical process, and if I recall correctly such processes are no more than 40% efficient... In other words, it does not look like the direction to persue.
The trick I think is to make a material that allows for a certain degree of free movement of charges, but that does limit this movement to a certain zone, effectively "pinning" the charges to that region, while retaining its crystalline structure. Relative p- and n- "layers" or "zones" should be present in this crystalline matrix, either causing a gradual shift from n- to p-layer over the entire "cookie", or alternating n- and p-layers throughout the entire "cookie", or mixed evenly though the entire "cookie" but with a clear polarisation applied (so all n- layers are oriented toward the positive electrode and all p- layers toward the negative electrode, even though there are no clear "layers" as such).
Additionaly, a path should be provided for electrons to follow, which leads them to and from the p- and n- zones...
What you see happening in the "cookie" you made, where the voltage seems to drop and flip polarity, then build up to a low value again, is to be expected of a material in which the relative p- and n- particles are shifted internally due to the applied electrostatic potential. First, the charges will follow the applied electric field, then when the field is
removed, residual effects of this electrostatic induction and distribution of charges can produce the relatively high output seen. If the material structure is stable enough, the p- and n- particles will remain in their shifted positions (to a degree again), and only when all residual charge has been removed from the material will you be able to see the effect of this p-n distribution as a form of pn-effect.

As for the Casimir effect, I must say Hutchisons mention of the effect surprised me, since I can't immediately determine how this effect could be used in any way to generate electrical ouput... Do you mention it merely because Hutchison does a number of times, or do you have a theory behind it?
The only thing I can think of where the Casimir effect might be usefull, is if we attach the two Casimir plates directly to two very sensitive pieces of piezoelectric material.
The two plates, attracted to eachother by zpe push, will "pull" on the piezo and this will generate a charge on the piezo surface. Of course, since Casimir effect only occurs at tiny seperation distances, the "pull" will be extremely small. Theoretically this Casimir force "pull" becomes exponentially stronger as the distance between the plates decreases. Obviously, the piezo material will have to be able to "stretch" far enough to allow this "pull" to be felt, but not too far as we want the plates to remain seperated from eachother. This is already quite difficult, and we must also remember that the plates need to be extremely flat (on the micro- and nanoscales) and parallel to eachother; needless to say this becomes more and more difficult the smaller we make such plates. Ok, so let's assume we managed to do all this, and the plates are attracted, and the piezo's "stretched" to the maximum. Now of course we want to harness the energy produced, so let's assume we have this setup connected to a simple diode bridge and a capacitor; the charges will flow from piezo surface to electrode (on the piezo) to diode (assuming we have tiny ultrasensitive diodes), to capacitor. Great. Now we have a situation with the Casimir plates closest together as our system will allow, and the maximum charges we can get from that Casimir force extracted through piezo's.
But now, the Casimir plates will stay where they are, because the Casimir force only "pushes" the plates together, and does not provide any mechanism for them to move apart again. To move them apart, we need to "pull" them apart by applying force again. We could apply that force by charging the piezo's oppositely, which will make the piezo's contract, and pull the plates apart. But that process is enthropic again, so the amount of energy we need to input into the piezo's to seperate the plates will be greater than the energy gained from the Casimir effect pulling the plates together...
I fail to see how energy could be extracted on the basis of that effect... That said, it may be worth studying the effect of frequency differences in respect to frequency shielding, which in a way is what happens in the Casimir effect. After all, if the abundance of energy at a certain frequency has a clearly observable effect, then the absence of energy at a specific frequency (or frequency range) may very well have similarly clear observable effects... Especially in the circumstance that said absent frequencies are normally present at relatively high intensities...
And of course perhaps there is more to the Casimir effect than meets the eye... Perhaps on the tiny scales of silicate platelets, the minute differences in chemical composition of these platelets may cause them to "feel" slightly different "pulls", or even cause the electrons inside them (or on their surfaces) to move about according to a certain frequency which is "seen" by both Casimir platelets, but not by the surrounding material, thereby generating an unknown "Casimir oscillation"... That might increase the overall oscillatory action of the material and might support electron flow mechanisms.
It is also possible that the tiny platelets act as tiny capacitor plates, the quartz as tiny oscillators, and the other elements as p- and n- material layers, thereby turning the entire "cookie" into a big heap of fairly randomly organised and minuscule LC+rectifyer circuits. Aligning those accoring to the right 'polarity' would allow for (part of) the resulting charges/currents to be directed to either "pole" of the "cookie". This sounds cool, but also seems to be the least likely interpretation. ;)
So you see, there are some possible views on how these "Casimir" 'platelets' may or may not be connected to energy generation in such a 'cell'. 
I'd like to hear your thoughts on this.

Ian, I have not heard of material becoming radioactive in a Tesla coil as such...
I have heard of unstable isotopes reacting to hV discharges by showing stimulated decay, and also of them fusing during such a discharge.
I suppose it may be possible to take a slightly unstable, metastable, or perhaps even truly stable particle and hit it with hV so hard that it gets knocked senseless and becomes unstable and emit radiation...
Why? Are you thinking of blasting some material with your TC in order to make them emit beta-particles?
If you want to do some hV experiments that may yield higher output, I can suggest a few... But they're totally unrelated to this thread though.

Kind regards,
Koen

Hi Koen and all,

I'll keep this brief cos I'm off to bed.

Yesterday I made another rock pie, (jeanna calls it a tart ). It's been with me all day at work with a meter connected across it. There it sat @ 0.431V. I put a 10k ohm load across it and it dropped to 33mV very quickly. It stayed that way for 1hr 10 min. When the load was removed, within seconds the voltage was up 0.420V. I repeated this a second time with the same result.

As with all batteries, if the terminal voltage drops sharply with a load then it indicates a high internal resistance. Measuring from + to -  read 6.2 Mohm  and from - to +  2.2 Mohm. So it would appear that a least I've achieved some semi conductor effect. I believe this is due to the conditioned electrode.

Still, small steps, as they say. Next stop, larger surface area and thinner substrate.

BTW this mix did not contain any tourmaline, just desert sand from Kalgoorlie Western Australia.
The sand is loaded with silicates and oxides. I also used 6000V to polarize it, and just to make sure, the pie was baked for 3 hours @ 300C to get rid of any water.

Koen thanks for your in depth explaination in your last post, most informative.

Kind regards  Ian

Ian and Jeanna,

I have come to posess a copy of a German research paper by a dr. D.Staschewski titled "Eigenpotenziale als Wirkung latenter Raumenergie",
which contains some very interesting information. Roughly translated the title means "Self-potentials as function of latent Space energy" although "Raumenergie"
is perhaps better translated as "Cosmic energy".
Assuming you guys don't read German very well, I will see if I can translate the relevant sections.
In any case, dr. Staschewski includes a summary of T.T.Browns petrovoltaic effect research, as well as his own research and tests of several materials.
He did measurements using photo-resistors placed inside Orgone accumulators,tested several types of photo-resistor, did measurements on self-potentials in gypsum, in agate stones, and in proton-emission membranes, using various materials as electrodes and measured at different temperatures, considered and compared possible effects of outside interference or influence such as climatological circumstances, compared series and parallel linking of the tested materials, etc.
I must read the entire paper extensively again, and then I will attempt a more detailed review.

Thanks Koen for sharing that information. I would be very interested in the types of results Dr Staschewski got with gypsum and what measuring equipement he used. I appreciate your time in translating it for us.

At this time, the "pie" is still going strong.  Repeated shortings has not decreased it's ability to return to it's 0.4 V output after a period of time. It does display daily fluctuations of +/-  0.02 V. I have now all but ruled out any galvanic effects. I am currently preparing some more electrodes for my next batch of "pies". Since my last post I have made 5 others with different mixes and electrode configurations but none of the results look very encouraging. I even made one out of doped terracotta modeling clay and pressed it into a beer bottle cap using a 5 cent peice as an electrode. Suprisingly after 4 days it is still puting out 0.38V . I was going to make another dozen more but after drinking all that beer just to get the tops,I was too drunk to proceed. ;D

I've also been analysing some of these reactions under my microscope. One can clearly see the effect of sodium carbonate solution on quartz grains. A crystaline coating of sodium silicate developes around each grain and eventually binds all the grains together. Trying the same experiment with a voltage applied across the solution did not show any form of crystal alignment. Also after a while atmospheric CO2 turned the excess sodium carbonate to white bi-carbonate and I could not see through it.
I'll try a get some photos of the crystals forming.

Heres an odd thing.  I mixed some borax with some sodium silicate solution to see if the borax would dissolve. It did and it remained a clear viscous fluid. I let it stand overnight and checked it in the morning. The idea of this was to somehow get some boron into the mix as a charge carrier.
The liquid was still clear and runny until I gave it a good shake and then it instantly turned into a stiff opaque gel. It was exothermic as well.  Koen or jeanna, any ideas?

Thats about it for now. I have a couple of days off so I'll be making some more mixes and repeating the borax experiment.

I'll let you all know what happens.

All the best

Ian

@Ian
Excellent, I would love to see a/some pics.
I have a microscope. I would like to know more about that.
You say crystals formed. was it a crystal then? I am thinking how powdery mine was when dry.
Did it ever become powdery?
Interesting. This is pretty much how Davidovits seems to describe how his rocks were formed. I wasn't seeing this. I assume you have the formula?
I am not a chemist. I remember in chemistry lab we made a supersaturated solution of something which stayed in liquid form until we struck the side of the container sharply. I suppose this is the reason you shook it?

@Ian,
I have been thinking about this siezing up of the solution. I will need to go back to the library. I read a book on chemistry for artists. In it there was some information about the crystalline structure of Silicon. There were 3 drawings.2 of tetrahedral-type structure and a third that was not tetrahedral but the elements were held together in tight strings but in non repeating form. But it was solid. I will be more specific, but it may take a few more days to get the book out from the library again.

G'day all.

@jeanna:  Thanks for researching that extra bit of info, every bit counts. It would appear I've saved humanity again. That white stiff gel I made turns out to be a form of SOAP!  ;D ;D ;D :'(
It's the best silver cleaner. lol.

The batch of mix I made yesterday was very dissapointing, in fact of all the mixes I have made, this one returned the lowest voltage, 120mV. However I have everything well documented so I'll know what not to do next time.

Here are a couple of photos of silicon carbide in sodium carbonate solution. Sorry about the focus.
As you can see there is a crystal bridge between the darker SiC grains. I'm not sure how much of the bridge is made up of sodium silicate. But keep these in mind for when I post the quartz grain photos.
I'll be setting that up today.

see you soon

Ian

g'day all,

jeanna, well spotted again. the colours around the crystals are visible , thats because I forgot to swing the polarizing filter out of the way  ::).

I made a small movie of the quartz/ NaSiO3 growth. It was very dynamic, unfortunately it's 200mb.
The "pie" is still sitting at 0.43V.
I'm working on a new formula for a mix but my hunch is towards electrode conditioning as the main factor. Nitridation. ( I think)

I'm going to the south coast tomorrow (Saturday) to collect a few kilos of pure quartz sand.
Might catch a few rays while I'm at it. ;D

All the best  Ian

Ian,
I have been thinking about your soap. I think it is getting close to what I have been looking for in the building material. You saw the growth followed by solidification.
Thing is soap is a salt made from the base, water and oil. So, there is no oil here but oil is a polymer. And the polymer formed by the Si is a likely substitute. So, your soap is a geopolymer. (Maybe you already got it and this is what you meant by soap the other day. and I am a little slow  :D .) Did you record the 'recipe' of your soap? I hope so.

@jeanna: lol :)

I think you may have a point here. Indeed, silicium polymers are the basic ingredient for the Davidovits geoplymer binders,
and indeed soap is generally a base+water+oil mix, somewhat similar to the composition of a salt. Since oils are polymers as well,
it is conceivable that you'd get a similar substance when we replace them with silicium polymers... On the other hand,
the chemical structure of "normal" (oil) polymers is quite different from the silicium polymers, both in structure and in chemical makeup...
Yet both soap base and most silicates are alkaline, so there we have a similarity again.

What I find particularly interesting is the sudden solidification and opacity of the substance after Ian shook it.
Your remark on loosely bound non-matrix silicon materials sounds likely... I believe I know what you're talking about, I think
I recall the same picture from some book on silicon chemistry. Must dig that book up again sometime.
However, I am not sure if this is of much direct value to our quest for a crystal energy cell...

@ian: Thanks for those pics! Can we download your 200mb quartz/Na2SiO3 growth movie somewhere?
Interesting remark about nitridation... Are you talking about "only" treating the electrodes this way,
or are you considering doing this to your new mix? (I ask because I have at some point considered
using nitrogen compounds in a mix to attempt to get rid of some excess oxygen and some other elements.
Since nitrogen is fairly inert to most chemicals, and has a very low boiling temp, I had hoped for the NO2
and NO gases to evaporate very quickly. The mix I had at that time did not respond as I had hoped, so
I dropped this approach.)

I just finished "cooking up" a nice new batch of silicate mixture, a fairly basic silicate solution which I had react
with several other elements, mostly sodium and a few very common metals, untill it turned into a paste. I've been
using small pieces of piping for containers, and have filled a few with this paste. Now I'm going to leave them to
solidify and dry for a while (anywhere between 1 to 4 weeks to ensure it's completely dry). Will test them all, and
if any test positve I'll post a pic. Unless you want to see one anyway, then I could post one for your enjoyment. ;)
Am also "cooking up" several variations of a substance with a similar base mix, but with different amounts of quartz
sand and/or metals in them. I took one fairly basic mix of mostly sodium silicate with quartz and "baked" it on relatively low heat
untill it was completely dry and hard. (lol yes, this was an attempt to imitate Hutchisons "shake 'n bake"/"dirt cheap"
video demonstration, without adding rock gravel.) I did this mostly to kill time while waiting for the other mixes to "cook",
but also because I just wanted to see how the quartz would bond with that specific silicate mix. The resultant "cookie"
looks very much like a sand cookie. At first it was quite solid but I guess there was still some water in it, because after a
day or two the thing became quite crumbly and broke in two. It is now very similar to sandstone, except that the structure is different,
and it is harder than sandstone, although rubbing the surface does loosen some of the "sand". There is absolutely zero voltage on this.
I must point out that I did not put any voltage on the material while it was "baking", nor afterward. (I did not have any equipment for this
in my workshop at the time, had taken my box of electrical thingys and whatsems back home for the weekend and didn't bring it.)
May try such a low heat "cookie" baking attempt again soon, but I need to remember to bring at least a capacitor, a battery and a multimeter... :)
But like I said, my focus at the moment is on my batches of silicate mixtures, and not so much on the "cookies". The fact that I currently do not have access to a kiln to actually bake high temperature ceramics may have something to do with that ;)

kind regards,
Koen

Jeanna,

yes, I am indeed planning to apply a reatively high voltage to some of the pipes while solidifying.
I'm working on a mix comparison to determine which exact mix I'll subject to the electric field.

Also, I have come up with this idea that simply applying a voltage while solidifying may not
have entirely the desired effect; if a (mostly) dielectric substance is subjected to such a field,
the molecules will not budge and the material will remain dielectric. However, many materials
are dielectric after cooling and solidifying, but are ferroelectric while molten. This means their
'dielectric' molecules will polarise according to an electric field. When this is done to a material
that is dielectric when solid (like quartz for example), a bias can be created in the material,
which can cause (quasi-)permanent 'polarisation' and a surface potential. Generally this is what happens in electrets.
But, if we look at materials that allow a flow of electrons through them, we quickly find
semiconductor p-n layers. The division of relatively positive and negative 'pollution' particles throughout
the semiconductor also creates a bias in the n->p direction, and electrons flowing through the material
will "want" to move from n to p and not in the opposite direction.
If we now look at the division of these positive and negative charges in the material, and we assume
it is possible to have a material that is both dielectric and has p-n qualities, then lets consider how
we could make this... Assuming we have this mystery material, the easiest way to create a seperation
of charges in the material, as well as a polarisation of the 'dielectric' molecules, is to apply an electric
field during solidifying and cooling. However both the polaritation direction and the p-n division will be
in the same direction: all positive charges, both those of the polarised molecules and of the p-pollution
particles, will be attracted to the negative electrode, and of course this is reversed for the negative charges.
If we draw the desired electric fields, we will see that this does not seem to provide a path for electrons to
follow from the one (positive) surface to the other (negative) surface through the material, since the
p-n direction is in opposition to the desired flow.
So perhaps it would be a good idea to make such a 'polarised' block, then cut it into slices, and rearrange
the slices in such a way that the dielectric polarisation is still all in one direction, but the p-n division
is in opposition to that...
That cannot be done by merely applying an electric field during the cooling/solidifying phase, but one
would need to cut the block into slices and rearrange them manually. Such a charge seperation
to my knowledge does not occur in rocks naturally.
And that is assuming that we can get the slices to connect perfectly, so that conduction etc actually happens.

comments or reactions are appreciated. :)

G'day all.

@Koen:  You,ve highlighted a problem I have been considering for a while. That is the polarization of the mix against the natural polarization of a p-n junction.  This probably why the polarity on my mixes reverse when the voltage is removed. I have and experiment going at the moment where the polarizing electric field (6000V) is insulated from the mix by mylar insulators. I will continue with this configuration for another week or so to make sure the mix is dry.

For the nitidation of the negative electrode I will heat treat the copper ( cherry red ) and then quench it in ammonia. The fumes will be fun. ;D
Not sure whether it will work but it is worth a try.

The silicon/borax "soap" has hardend over the last couple of days and now I cant get the stuff out of the pot. I can dig bits out and it has the same consistancy of hard parrfin wax. It looks like a very suitable candidate for an electret.

To make the stuff I dissolved 229gm of sodium meta silicate in 250ml of hot water, this makes a viscous solution of sodium silicate.
I let that stand over night to cool. It gets a little thicker.  I then used 60ml of that stock solution and added 1/4 teaspoon of borax.
Stirred until dissolved. That stood over night and was still a clear fluid.  I then gave it a good vigorous shake( just for the hell of it) and then it turned into a solid.

Like yourself I have made a number of sand cookies and they became brittle and crumbly.

After another 12 hour short circuit the "pie" bounced back to 0.480V.  :)

More later
