This SiC heating element seems to match perfectly the data from the report.

I’m not sure about the absolute values per wire, but the relationships are apparently correct. The resistance drops about 1/3.5 from 450 to 1200 deg C and remains then constant until 1400 deg C.

UPDATE: I heard from Andrea S. who has admitted this document was not genuine — see this message below:

Dear Frank,

As you probably suspected, there is no Sic Industries LLC, it is a little practical joke on some  Cobraf bloggers who were prompting me to assess feasibility of the three-fold resistance drop.
I  didn’t mean to make fun of you at E-Cat World, let alone the MFMP who is doing a fantastic job in the quest for truth: their investigation is key to understand whether the optical thermography  can be trusted.
I am not qualified to argue on that part. I have posted a critical review of the power input data of the TPR2 where I didn’t rule out the possibility of a nonlinear resistance as (tardively) claimed by Rossi, rather I showed that if one does assume this nonlinearity, then the infamous Figure 5 doesn’t match the expected pulsewidth.

Nevertheless I did give a look to the possibility that the dogbone may embed a SiC resistor. It is highly unlikely, but one willing to attempt a replication may use this datasheet as a requirements specification for a (real) resistor manufacturer.
Please forgive this little trick of mine.
Best regards,

    I this product and alloy???? coud you put 3 of them in phisical parallel and connect then in 3phase?

    • SG

      Based on the drawing, it appears that it is a single SiC heating element with built-in terminals for 3-phase power. So I don’t see why you would want to connect 3 of them in parallel. Am I missing something?

      • Dr. Mike

        SG,
        You are missing something. If you look at the diagram carefully, you can see the light gray wires above and below the black wire at the end of the coils. These represent the other two windings. Also, follow the black wire from one end. You can see its pitch as being every third coil. You can not connect all three phases of a 3-phases supply to the same node (i.e. an end of a single resistor). Each supply phase needs to be connected to a separate coil.
        Dr. Mike

        • SG

          That is why I was questioning ivanc’s suggestion of hooking three of these up in parallel. I think ivanc was missing something, not me. In any case, on closer inspection of this document, it looks pretty fishy. No corresponding website, etc.

          • Dr. Mike

            SG,
            Ivanc is saying the coils are physically parallel to each other but they are connected in a delta electrical configuration (each resistor is connected across one phase of the supply). The data sheet appears to me to be a product that someone special ordered (Rossi perhaps) and the company decided to offer it as a product or as just as an example of what they can build.
            Dr. Mike

      • Anon2012_2014

        I think it has three heating elements that are spiral wound, i.e. one starts at 120 degrees, one starts at 240, and one at 360. They never need to intersect each other from one end of the element to the other this way. See the Rossi paper schematic resistors (elements).

      • ivanc

        Yes, the ecat should have 3 of them physically in parallel and electrically in delta

            I said physically in parallel, not electrically, they should be electrically in delta.
            if they wound crossing wires they will be an issue.

          • Bob Greenyer

            It is in Parallel, I asked for exactly this kind of structure from SilCarb india.

            Currently they are considering a wye (star) configuration that I sent them a drawing for as this would be easier, particularly from a structural point of view.

    The dimensions roughly fit the interior dimensions of the Lugano ECAT.

    And while we are at it, could not the shadows on the picture of the operating ECAT be the gaps between the SiC coil windings?

    Finally, I am trying to look at some relationship between the intensity of the glow — it is brightest where the alumina shell appears thinnest in casting. I would have expected it to be brighter on the bottom of the cylinder where the 1 gram (about half teaspoon full) of fuel should be resting.

    • Dr. Mike

      Anon2012_2014,
      You might be right that the shadows in Figures 12a and 12b are shadows between the SiC coil windings. I also would have expected the bottom of the alumina cylinder to be much hotter than the top.
      Dr. Mike

      • Bob Greenyer

        We have already shown evidence of hotspots on the top on a levels adjusted photos from the report.

        • Dr. Mike

          Unfortunate to see that the cited spec sheet now how a disclaimer saying that everything was made up to fit the Lugano report. So we still need an explanation from the authors.
          Dr. Mike

    • Bob Greenyer

      Light will refract and concentrate in the gaps between the coils, I may try to simulate this in a 3D rendering package using full spectral rendering techniques. To see an example of this “light concentration” effect look at the photo of the 2nd dog bone cast in the furnace at 1200ºC where it contacts the ground.

      It will also likely be related to the ability of structure to emit/loose its energy through radiation or convection

      • Anon2012_2014

        Bob,

        My thermodynamics is ancient, but I have just read recently about how objects look in a kiln oven — it is partially emissivity (emission radiation), partially reflection, partially refraction, and even partially transmission. So that the brightness of a spot on the image is not necessarily the heat of the object, but also the heat reflected, refracted, or transmitted from the same spot; i.e. it is a complex problem with a non-trivial solution.

  • SG

    In a friendly debate with Dr. Mike in the previous thread, I stated:

    “Is it possible that a single SiC spiral heating element is present
    within the reactor? Yes. Would having a single resistor connected to
    three phase power lines make sense? I don’t know, but maybe.”

    Interesting to see evidence of such a possibility before our very eyes.

    • Dr. Mike

      SG,
      This heating element would not only fit, it is probably the data sheet for the Hot-Cat heater. The Lugano authors can correct this portion of the report by just saying that a 3-phase SiC heater element was used. The data sheet says this is a 3 phase coil, not a single phase SiC coil. You can see the 3 phases in the diagram where the light gray wires above and below the black wire are the other two phases.
      There are still one or two other questions that I would like to see answered. This heating element’s maximum temperature spec is 1650 C. Why didn’t the authors at least run the dummy run up to somewhere in the 1250-1400C range? My other question will probably require a thermal engineer to answer. From specs on this heating element, it appears that the maximum power for this element is 1250W with a maximum temperature of 1650C. Would it be correct to assume that this 1650C max temperature is reached at about 1250W? If so, this heating coil should reach a temperature of 1400C at an applied power of 1150W +/-50W. The second part of the active run had an input power of 900-920W. Why did the reactor need a calculated ~2300W extra power produced from LENR reactions to reach 1400C when the same temperature could have been reached by just applying 200-300W of electrical power to the heating coils?
      Dr. Mike

      • Anon2012_2014

        Dr. Mike,

        I’ve been thinking about that. The maximum temperature is probably not the maximum that the unit would put out (if it was in a small insulated chamber), but instead probably the temperature where some portion of the element would fail (i.e. an internal short, or a structural failure). At 1250 watts the unit will run cooler if it is in air with a fan blowing on it, and much hotter if it is in a small insulated chamber with reflecting foil on both sides.

        • Dr. Mike

          Anon2012_2014,
          Do you have any estimate of what the temperature might be for the heater coils covered in alumina with no fan? I guess you also have to add the little fins on the alumina coating.
          Dr. Mike

          • Anon2012_2014

            Dr. Mike,

            This is an undergraduate’s homework (problem set) item in thermodynamics. I think the calculation would take about 20 minutes (including double checking) for someone who just completed the course. I am older and its been a long time — it will take me a few hours and I still might get it wrong. I have another set of problems for a buddy to work on first.

      • LCD

        1400 C is on the surface of the alumina. We assume the core is much much hotter, that is the fuel core.

        But this brings up an interesting point. Why is the internal cylinder 20mm in diameter. I mean it is just 1 gram of powder. I feel like that is mostly empty space, for what. What else is in there?

        • Dr. Mike

          LCD,
          The core can’t be too much hotter or all of the Ni powder would have melted.. We don’t know the internal diameter of the cylinder. I calculated the thickness of the alumina cylinder based on the total weight of the reactor and the density of alumina. For alumina that is on the low side of its range in density the thickness of the alumina would only be about 2mm or so. (I need to, re-do this calculation based on the 4cm end cylinders not being solid except for the end 1 cm in length on each end. Also if the coils really had been Inconel, about 30 gram of total weight would have had to have been subtracted reactor weight to calculate the net weight of the alunina.) There would be a whole lot of empty space! I would guess that the reason the Hot-Cat is designed this way is because it is designed around the 3-phase heater.
          Dr. Mike

        • Bob Greenyer

          There will be the Alumina reactor core inside.

          • LCD

            Well how big is the actual hole the powder goes into?

          • Bob Greenyer

            approximately 4mm as per the drawings on our proposal and based off the Lugano report.

          • LCD

            Okay that’s still pretty big compared to the powder charge

      • Bob Greenyer

        That is the maximum surface temperature. The volume and surface area of the Lugano reactor is FAR larger than this heater element (assuming it is genuine and not an elaborate piece of fun) and so would be able to radiate and convect more energy.

    Item is substantially similar to the item in this 1973 patent: http://www.google.com/patents/US3859501 (since expired)

    Patent is licensed originally to this Squared R Element Company Inc.

    They are still in business although I see no spiral three phase items in their catalog, I see plenty of three phase and plenty of spiral items (including a double wound so you could power it from one side only). I am sure that this is an easy custom job.

    I can’t find the Sic Industries LLC in Charlotte, in the NC or DE secretary of state registry. There is a SIC Industries in AZ, but I believe it is unrelated — they fabricate larger parts out of steel. It looks like a welding shop to me.

    The pdf was created in January by SiC Industries LLC. I’d like to know where the contributor got it from. Charlotte is interesting because that state is where IH is from.

    • Bob Greenyer

      This is the kind of element I am getting a quote from SiCarb India, It would be connected in star with no neutral. The advantage is there would be twice the resistance because of the connection type.

      I have been speculating that contacts at one end may be fake as most of the photos of hot wires are from the other end.

        Bob,

        A few comments that you may or may not find useful:

        First, Rossi shows a delta, not a Wye (“Y”). My first thought was that the only reason he went for a three phase setup is that European wall power for high power machines is three phase. Now he sends it through a triac power regulator; i.e. this is the simplest way for him to draw 1200 to 1600 watts from the wall in Italy or Sweden.

        Second, this is the company that is the successor to the 3 phase SiC patent I showed you above: http://www.isquaredrelement.com. It’s founder was the inventor. They are based in New York. I doubt they are any cheaper than your Indian supplier, but they have made these before. I don’t see any spiral three phase units with electrodes at both end in their Starbar catalog, but I am assuming that they manufactured them before around the time of the patent as they probably needed a spiral three phase unit at the time for a European (power) based application; and hence the patent.

        Third, is that, although we cannot know for sure, I see no reason that you need a three phase heater at your U.S. labs. In iSquared’s catalog, the double spiral is clearly made so that the electricity only needs to be supplied (single phase or DC) on one end. Otherwise, single spiral (single phase power) may do the trick for you. This is cheaper than having a custom element made. Also, you may be able to shrink the length of the reactor to get the same power per linear cm without having to drive 1200 watts in.

        Good luck Bob,

        Anon2012/14

        • Bob Greenyer

          Thanks.

          We are actually looking at single phase windings that will be much cheaper and able to go to 1250ºC enough for someone to screen materials. We have been quoted as little as $22 here in Czech

          Standard single phase SiC element would suffice also and be able to run at the higher temperatures.

          But to give people the whole picture we need to see what options there are and whilst it may take time and intellect, there is very little cash spent in establishing the state of the art.

        Rossi has stated that the heating/reactor also contains Inconel, or is based on Inconel. I searched for “silicon carbide inconel” and found this paper which concludes sticking both together doesn’t work out very well.

          Gerrit,
          The Lugano reactor does contain Inconel.

    This document is very suspicious. It looks like a website, yet it escapes the claws of search engines. @Frank why don’t you give that phone number a call, and drop an email to that inbox, see if you get anywhere. ALso, does anyone have the link to the cobraf forum thread that exposed this document?

    • SG

      On closer inspection, I’d have to agree. Looks like some more sleuthing is needed.

    • Frank Acland

      This is the cobraf thread, Patrick http://www.cobraf.com/forum/topic.php?reply_id=0&topic_id=5747&ps=20&pg=9&sh=0

      This document is uploaded to the forum by Andrea.s on November 25, 2014 02:04

      I don’t see a phone number on the document, and the email address is a gmail address that anyone could have created. I think this should be treated with caution at this point.

      • Frank Acland

        I sent an email and got this response:

        “Thank you for your interest in SiC Industries LLC.

          Hi Frank. There is a number, although barely visible. It’s on the top right corner. It reads: 704 264 0133

      • Andreas Moraitis

        The phone number is
        (704) 264-0133 (next to the gmail address).

        • Frank Acland

          Ok, thanks. I called the number which is in the Charlotte, North Carolina area code. I got two rings then got disconnected. No voicemail. It is 11:15 p.m.

          • Josh G

            Charlotte, NC — near Raleigh, where Industrial Heat is located. Makes sense…

  • Andreas Moraitis

    If I had known that Frank would quote this comment, I would have paid more attention to the wording. Actually, I meant that the resistance drops to 1/3.5 of its initial value, or by the factor 3.5.

    Interestingly, 3.5 is almost exactly the average COP. This would certainly be stuff for new discussions, if the active run had been carried out with a constant input. But fortunately, there have been two phases (day 1-10 and 11-32) with different input settings. The average COPs for them come to 3.18 and 3.66.

    I’ve been wondering about containing multiple cells/reactors in a compact way such that their magnetic or heat resonance is generally similar to a car’s engine (ie pistons firing in order to maximize power) with the energy from one lending itself to another on its downstroke and stoking the upstroke of another cell.

  • Andre Blum

    Can someone explain the significance of this discovery? Is this good or bad news? What data from the report does it match? The data of the dry run? Was it andrea.s who posted the paper about the reversed clamps?

    • Freethinker

      News and news… It is a fact that pathoskeps who recently have frequented this site claim to be impossible. It means the joule heat “argument” has an explanation and can be ignored.

      It means that the input power measurements can be trusted, which it could be before too, but not for those who look at such things which not is and is not known, to draw their ill founded conclusions and loudly voice these opinions as evidence of wrong doing.

      So yes. It’s good.

      • kdk

        Not to mention the stupid amounts of transmutation replications. Yeah, this has already gone on for decades long enough. Nice words are way beyond patience compared to the lives sacrificed. Keep it up and their idiot genomes might be one of the few thousand left on Earth, good luck and have fun.

    • Andreas Moraitis

      As Freethinker says, it’s good news. The diagram in the document shows the relation between temperature and resistivity of the wire, which is in accordance with the values that have been inferred from the data in the report – regarding both the dummy run and the active run. And yes, this has apparently been posted by Andrea S.

      By the way, the “inverted clamp hypothesis” can already be excluded by the fact that under full load the difference between the readings of the two PCE-830’s (before and behind the control box) was identical with the nominal power consumption of the box (see p. 5 of the report). This idea has been brought up by US_Citizen71. However, the new document makes it possible to explain the observed resistance drop in an easy way, without introducing exotic assumptions.

    • LuFong

      This is very good news and strengthens the report in my view. It explains some inconsistencies with the data and the statement that the resistors were braided Inconel cables.

      It also means the the MFMP []=Project Dog Bone=[] may be in a much better position to check other aspects of the report. I wonder how much these heater elements might cost?

      • Gerrit

        If the spec explains the “inconsistencies” then they weren’t inconsistencies to begin with. It was just that you couldn’t explain at that point how the data came about and therefore you concluded the professors made measuring mistakes.

      • Bob Greenyer

        Whist we reserve judgement on the provenance and authenticity of this document, other suppliers will provide SiC based elements for $150 a piece, which is well under an order of magnitude cheaper than some of the other options we had been looking at that would reach this temperature reliably for long periods of time in air.

      • Bob Greenyer

        as suspected

    • Gerard McEk

      It could well be that IH is using this element for the Hot cat (at least the Lugano version). As others say MFMP should seriously consider to use this for their tests.Good find Anderas, I am sure it makes the Lugano tests more acceptable, even for those who were puzzeled about the resistance properties!

  • Gerrit

    Rossi has stated that the heating/reactor also contains Inconel, or is based on Inconel. I searched for “silicon carbide inconel” and found this paper which concludes sticking both together doesn’t work out very well.
    “Brazing of reaction-bonded silicon carbide and Inconel 600 with an iron-based alloy”
    link.springer.com/article/10.1007%2FBF01129945

    • Dr. Mike

      Gerrit,
      The Lugano reactor does contain Inconel. From the report on page 3: “Three braided high temperature Inconel cables exit from each of the two caps: these are the resistors wound in parallel non over-lapping coils inside the reactor.” However, the report should have said: ‘Three braided high temperature Inconel cables exit from each of the two
      caps: these cables are connected to three resistors wound in parallel non over-lapping coils
      inside the reactor. The resistor material is proprietary.’ I don’t believe Rossi realized that by not telling the professors that the Inconel wires did not form the resistors that the final report would have an unexplained inconsistency in the electrical data.
      Dr. Mike

      • ivanc

        The most probably scenario is that Rossi told the professors the resistor were made of inconel, Rossi itself after says the element are a special alloy doped with inconel.
        note the word alloy, so is made of metal.

    • Anon2012_2014

      Most of the SiC have aluminum “tinned” connectors on the cold side. I am assuming that some kind of nickel-steel spring crimp can be made from Iconel that makes sure electrical contact with the SiC/aluminum and does not oxidize.

      Rossi then just brings the Iconel out of the ends of the reactor to the power supply within the “tubes”.

      Whether the heater coils are Iconel or SiC, no one knows. SiC does seem to have good properties for a heater. I do question however whether the nickel metal in Iconel could participate in the reaction. I also question the H2 or D2 gas pressure within the Rossi Lugano reactor. Finally, if all the power is being made from 1 gram (half a teaspoon full) of power on the bottom of the reactor, why does not that hot spot cause either the alumina or the heater coils to fail in the Rossi reactor?

      I am very much looking forward to Bob/MFMP getting some live data and exploring these areas. As usual I am annoyed by Rossi for hiding 90% of the experiment in a secret pipe that is never disassembled. This is why open science beats closed science.

  • Charles

    Maybe someone can talk Silicon Carbide into publishing a schematic so we can stop speculating about WYE, DELTA w/GROUND SINGLE PHASE or blah blah blah.

    • Bob Greenyer

      This unit (if genuine) would be suitable for Delta as detailed in the report. It is the kind of design I first requested a quote for from SiCarb India, but they said it was not practical to make. I have suggested a unit that would be suitable for WYE connection, this would be more robust, easier to make and to connect to for wide scale distribution.

    • Obvious

      I see what the professors did.
      Now I’m just just trying to rationalize why they did it.

      Check this out (using Run1):
      Extrapolated I for Run1 = 46.669 A ; therefore Ip = 46.669/sqrt(3) = 26.994 A
      Jhc1 = 3*((Ip^2)*(0.004375)) = 9.528804 W
      Jhc2 = 6*((Ip/2)^2)*(0.002811) = 3.061196 W
      Jhtotal = Jhc1 + Jhc2 =12.59 W
      Then Jhtotal * 3 = 37.77 W

      Using this same method, Jhdummy = 6.73 W
      But the line current is of course what they used (or seemed to describe) in the report for the dummy.
      The line current calculation for the dummy does give the same answer, if not multiplied by three.
      Now you have to decide what is the right one for the report…..

      Cheers!, Enjoy your weekend.
      Edit: It looks like the Jhtotal for the dummy must be multiplied by 3 to fix this up…

      • ivanc

        So why you pushed the Idea of SiC if is not really possible, this kind of speculation is the fog to reach the truth and the hope of the pathobelievers.

        • Bob Greenyer

          The reasons are clear and have been discussed widely before on other threads. SiCarb India did not say impossible. Principally, it is possible to make in pretty much any shape you like and can have incredible range of properties depending on what additives it includes. Is it commercially viable – can a company be bothered? What I have learn’t over the past several weeks is that if you ask for an element from a furnace element manufacturer – they will listen to what you want and then they will try and sell you something they already make a lot of that they think will do the job.

          It was a thinking exercise and because of the wide discussion surrounding the impossibility of NTC – it was necessary to share the thinking, this is LOS not all answers are known in an instant.

          The fact that it was discussed and this clear spoof was made (I don’t know if you noticed my repeated caveats in my postings on this thread before the ‘outing’) led to the discovery of the very real patent for a 3 phase SiC winding. This was a very good outcome.

  • Bob Greenyer

    It is in Parallel, I asked for exactly this kind of structure from SilCarb india.

    Currently they are considering a wye (star) configuration that I sent them a drawing for as this would be easier, particularly from a structural point of view.

  • Finally the file have been edited by Andrea.s and it is a fake.

    • Andreas Moraitis

      It comes now with the following description:

      “This spec was put in the form of a product datasheet, but there is no Charlotte-based SiC Industries LLC, this was a practical joke for the Cobraf Forum members, some of whom had challenged me to assess feasibility of a SiC resistor compatible with the Lugano report. It may serve as a tentative requirement spec for a (real) SiC resistor manufacturer, though likely not feasible due to the high doping required (assuming 0.01 ohm cm, the lowest advertised on advanced material websites, one gets roughly a 0.6mm thickness to achieve 0.4 ohm). However the temperature dependence was made up to match the Lugano report data: no real data behind.”

      • Anon2012_2014

        I suspected as much (that it might be a fake) when I couldn’t find anything about the company on the internet. The temperature dependence was too close to the Lugano report. Looked weird.

    I am very happy to report that we knew enough to see that this was obviously a fake from the outset and said as much when it was posted to our Facebook page yesterday.

    I didn’t even bother sending an email or phoning them yesterday – because when you understand the industry this was rubbish.

    What helped us was that we had already been told by SiCarb India that such a product was impractical to make.

    However, we must sincerely thank the authors however, because their, quite obvious joke, led to the discovery of a very real patent supporting a request that we had already made to SiCarb to make a 3 Phase element in a Y (star) configuration. This could be very practical for wide scale material screening.

    http://www.google.com/patents/

    Which was discovered by Anon 2012_2014.

    So A REALLY BIG thanks to him and the authors of what we called the “Spoof”.

    • by the way I found an interesting reference in that article

      http://furnaces.911bob.com/electric_resistance.htm

      there are some (Fe-Cr-Al) alloys that may work at 1400C but not with the 3x negative temperature coefficient

      maybe zirconia can be an alternative…

    • Ophelia Rump

      Bob, Have you tried shopping the specification out to manufacturers for pricing to see what their people say?

      • Bob Greenyer

        We had already asked for something like this from SiCarb, and they would rather we took a standard 3 phase element – element manufacturers are not to keen to get involved in research, Particularly the split at both ends made this kind of approach fragile.

        We had already requested they produce a quote for a Y – type, we have what we need to assess the Al2O3 thermal aspects of the report vs power in and tomorrow I should receive some “Fat” coils we can use to verify the visual questions in the report.

        After that, it would be good to have an affordable, robust (for shipping) and convenient element that can be used as a platform for wide-scale material screening, if we can get SiCarb india to produce the element, we will be in a strong position. Though one could argue only a single phase one is needed.

        Other materials that run at 1400+ºC for long periods of time in air are stupidly expensive!

        We past the patent for the 3 phase element (that matched our own request) onto SiCarb india for additional clarity.

    I am very happy to report that we knew enough to see that this was obviously a fake from the outset and said as much when it was posted to our Facebook page yesterday.

    I didn’t even bother sending an email or phoning them yesterday – because when you understand the industry this was rubbish.

    What helped us was that we had already been told by SiCarb India that such a product was impractical to make.

    However, we must sincerely thank the authors however, because their, quite obvious joke, led to the discovery of a very real patent supporting a request that we had already made to SiCarb to make a 3 Phase element in a Y (star) configuration. This could be very practical for wide scale material screening.

    http://www.google.com/patents/

    Which was discovered by Anon 2012_2014.

    So A REALLY BIG thanks to him and the authors of what we called the “Spoof”.

      Bob,

      “So A REALLY BIG thanks”

      No problem. You are doing the heavy lifting.

      Big thanks to you and the MFMP team.

        It is so important in LOS for the crowd to contribute, and you get the credit for this along with the obvious joke pdf creator Andrea S.

        When I made the request to SiCarb to produce a 3 phase helix coil – I was just thinking of something that could actually be practical for wide scale screening, to know that this had already been patented and with great list of advantages (including filling the gaps with a ceramic) was helpful, in fact I have passed the patent along to SiCarb to help with the quote they are preparing.

        A unit like this would make it easy to insert a reactor core at the opposite end to the contacts and TC, really neat.

          HI Bob ,
          of course a professional would not fall for it, I know you did not. Though a company without a website was implausible (and to buy a domain for a wee joke was too much), a resistor with that shape is not impossible, and yes I was imagining to partly fill the gaps with ceramic.. Probably the 0.4 ohm is not achievable as doped SiC, not sure about 1.2 ohm.
          I think Ryan’s spec is more difficult to implement 🙂

            Seriously though Andreas, you enabled the finding of a patent that is helping SiCarb india understand what we want for a *practical* high temperature element.

            We have always said, from the founding day of the MFMP, that for LENR, it does not matter who releases it first or how, it just matters that it happens.

    • by the way I found an interesting reference in that article

      http://furnaces.911bob.com/electric_resistance.htm

      there are some (Fe-Cr-Al) alloys that may work at 1400C but not with the 3x negative temperature coefficient

      maybe zirconia can be an alternative…

      it seems it is even more NTC than SiC

      Bob, Have you tried shopping the specification out to manufacturers for pricing to see what their people say?

      There is no better technical source than asking they folks who make the things for a living how much to make one to that specification. If they can’t make it, they will not try to sell you a box of them.

      • Bob Greenyer

        We had already asked for something like this from SiCarb, and they would rather we took a standard 3 phase element – element manufacturers are not to keen to get involved in research, Particularly the split at both ends made this kind of approach fragile.

        We had already requested they produce a quote for a Y – type, we have what we need to assess the Al2O3 thermal aspects of the report vs power in and tomorrow I should receive some “Fat” coils we can use to verify the visual questions in the report.

        After that, it would be good to have an affordable, robust (for shipping) and convenient element that can be used as a platform for wide-scale material screening, if we can get SiCarb india to produce the element, we will be in a strong position. Though one could argue only a single phase one is needed.

        Other materials that run at 1400+ºC for long periods of time in air are stupidly expensive!

        We past the patent for the 3 phase element (that matched our own request) onto SiCarb india for additional clarity.

        My business partner is in India and can receive sample pieces if they will make them.

    The reasons are clear and have been discussed widely before on other threads. SiCarb India did not say impossible. Principally, it is possible to make in pretty much any shape you like and can have incredible range of properties depending on what additives it includes. Is it commercially viable – can a company be bothered? What I have learn’t over the past several weeks is that if you ask for an element from a furnace element manufacturer – they will listen to what you want and then they will try and sell you something they already make a lot of that they think will do the job.

    It was a thinking exercise and because of the wide discussion surrounding the impossibility of NTC – it was necessary to share the thinking, this is LOS not all answers are known in an instant.

    The fact that it was discussed and this clear spoof was made (I don’t know if you noticed my repeated caveats in my postings on this thread before the ‘outing’) led to the discovery of the very real patent for a 3 phase SiC winding. This was a very good outcome.

    A post on 22passi.blogspot.com provides a link to this document from Kanthal about Silicon Carbide heating elements. On page 12 there is technical data that shows interesting resistance data at various temperatures:

    http://heatingelements.hitempproducts.com/Asset/Silicon-Carbide-Electric-Heating-Elements.pdf

    • Andreas Moraitis

      The purple curve in the diagram on page 12 shows a ratio of resistances between 450 and 1200/1400C of about 1.75/1.45. Not enough to explain the behaviour of the E-Cat’s coils, but it points in the right direction.

      • Andreas Moraitis

        By the way (question to the EE’s here): Since the coils have a certain inductance, the waveform should influence their apparent resistance. Would that influence be sufficient to explain a significant drop in case that the waveform has been different during the active run?

  • Obvious

    I see what the professors did.
    Now I’m just just trying to rationalize why they did it.

    Check this out (using Run1):
    Extrapolated I for Run1 = 46.669 A ; therefore Ip = 46.669/sqrt(3) = 26.994 A
    Jhc1 = 3*((Ip^2)*(0.004375)) = 9.528804 W
    Jhc2 = 6*((Ip/2)^2)*(0.002811) = 3.061196 W
    Jhtotal = Jhc1 + Jhc2 =12.59 W
    Then Jhtotal * 3 = 37.77 W

    Using this same method, Jhdummy = 6.73 W
    But the line current is of course what they used (or seemed to describe) in the report for the dummy.
    The line current calculation for the dummy does give the same answer, if not multiplied by three.
    Now you have to decide what is the right one for the report…..

    Cheers! Enjoy your weekend.

    Edit: It looks like the Jhtotal for the dummy must be multiplied by 3 to fix this up…COP still >=3

    Edit2: If Jh is left at ~6.7 (report style Jh), then the active Jh is then 1/3, then the COP is still >3 except for run1 at 2.98 COP (0.02 COP difference between methods)

    • Anon2012_2014

      Mr. Obvious,

      Here is what I did to simplify.

      Each C1 copper line + 2 * C2 copper lines can basically be simulated as three resistors: the two C2’s in parallel and the one C1 in series with the other two leading to the reactor. That means that the resistance for each C1 + 2 C2 assemblies is

      R = 4.375e-3 + 0.5*2.811e-3 = 5.7625e-3 Ohms. Put this in a cell on your spreadsheet.

      The power Joule heating into each C1 + 2 C2 is 1/3rd of the total Joule heating.

      Therefore, the estimated current in each C1 + 2 C2 assembly is:

      I_estimated = sqrt(P_jouleHeat/(3*R)

      So 37.77 watts of Joule heating yields a per assembly current estimate of 46.74 amps, as the dummies test of 6.7 watts yields 19.69 estimated amps — within rounding error of the 19.7 amps reported by the Professors.

      So the only thing that is weird is assuming a constant resistance how does 49 amps in test 15 get only 863 watts from the heater (subtracting the joule heat), when the dummy test has 19.7 amps getting 479 watts from the heater.

      Put another way, if we treat the heater as some kind of giant RMS heater, its average resistance is apparently 0.41 Ohms in the dummy run vs. 0.12 Ohms in in the ECAT runs.

      Maybe this has something to do with the reactive load on the coil. I doubt it at 50 Hz, but who knows. Maybe this has something to do with the Triac’s wave form, but RMS is RMS.

      The professors would have made life easier by supplying both the voltage and the current at each leg. I believe that at least some of the PCE 830’s power measurement modes use RMS voltage and current (or maybe all of them). What is the big secret about RMS data?

      • Obvious

        One of my improved versions has 0.399 Ω for each resistor, once Joule heat is corrected properly, after extracting the current used for the original calculations.

        The effective delta resistance is 1.269 Ω “cold” and drops to 1.1777 Ω at peak temperature. This might be due to rounding the input Watts, so it may not actually drop, although it seems consistent. It could also be due to the copper cables heating up slightly.
        (I’m still looking at these R numbers since I have two versions, one with 1/3 active run Joule heat, and another with 3x dummy Joule heat, and I’m still fiddling mentally with what R is the real R, since the 0.4 Ohm may just be the Wye equivalent and not the actual R, which should be higher than the effective R, and is probably actually ~1.75 Ω.)

        One volt reading and we probably could have put this bed ages ago. Probably the professors would have caught their error also when writing the report, and it would have been a non-issue….

        I was able to extract from the Joule heat figures the combined resistance of one C1 and two C2 in parallel in one version. And three sets of these in my other version.
        I have for a set of C1+2C2parallel = 0.0057805 Ω

      • Obvious

        For obtaining the active run current I did the following:
        Divide each Joule heat value by the dummy Joule heat W. (=1 for the dummy)
        Get the square root of the value above. (This makes a factor for I, rather than I^2)
        Multiply the above new factor by the dummy current (19.7 A) for each run.
        This gives the current for each active run.
        This result agrees exactly with the one obtained by the alternate route used by others.
        For the parallel C2: (Rc2*Rc2)/(Rc2+Rc2)

  • Thomas Clarke

    Obvious – I don’t want to duplicate comments. I’ve commented on your material on the other thread and I believe currently we are in agreement that there is no way to explain the X3.3 except a measurement error or a resistance that mysteriously drops by 3.3 X between the dummy 500C and the active 1250C tests.

    • Obvious

      Measurement or more likely a data handling error, IMO.
      The negative resistor is a COP out.

      Edit:The weird part is that phase current for C1 as well as C2 is required to exactly fit the data supplied.

    • Anon2012_2014

      Agreed — no way to explain the heater element power with the paucity of data provided by the authors of a 50+ page report! I mean, come on Levi et al; do us all a favor and show us the voltage and current sampled at one time for the dummy and for one of your runs. This riddle is a waste of intelligent peoples’ time.

      • Obvious

        The riddle was a good one.
        There is only one good solution, and a whole bunch of mediocre ones. The mediocre ones all have some sort of semi-fatal flaw once all the calculations are run and the facts are examined and compared to the assumptions that form the various sub-par models.
        The good solution has another mystery buried in it. One that does beg for an explanation or clarification from the professors. Although it does not affect the results, the omission of an important fact regarding the test is unsettling to me.
        There are several good explanations possible for what was done, but I would like to hear the official response.
        The voltage is easily extractable from the available data, but obtaining the correct voltage for all runs requires knowing something else that was not reported.
        And the Joule heat still needs some fixing to be accurate for all runs. Even the resistance used isn’t quite right, although it is close. It would be handy to know if the wire was solid copper of not. I doubt it. That has a slight effect, but when we are talking about calculations using figures to the millionths of a ohm, it does affect accuracy somewhat.

        • Anon2012_2014

          Voltage: the PCE-830 has three obvious voltage probes plugged into it, presumably coming out of the power supply going to the PCE-830. So the 830 should have recorded the voltage along with the current at each logging interval (say once per second). No need to know or guess resistance — all that data should be there. The rest is unnecessary obscuration of the facts. This is annoying.

            The data provided is sufficient.
