Replication Thread

The most recent E-Cat test has given us another piece of evidence about the operation of the E-Cat with new clues about what makes the reactor work and what might be behind the reactions taking place. Replication by outside entities could help with the patent application for the E-Cat, since one requirement for patent approval is that someone of normal skill in the art could build a device.

As far as bringing more attention to this technology, I don’t think that there will be anything that will help with that regard more than successful outside replication.

With this in mind, I have created this permanent thread here on E-Cat World where comments on the subject can be kept in one place and which will not be buried over time where discussions about replication can take place.

    Proposal for an experiment – only suitable for those who are able to handle hydrogen at high pressures and temperatures.

    Ingredients: nickel powder, zinc powder, thinned hydrochloric acid.

    Mix the powders and put them into the reactor. The oxygen can be removed by pouring in an inert gas. Add some of the hydrochloric acid and close the vessel quickly.

    The zinc and the hydrochloric acid will react and produce hydrogen:

    Zn + 2HCl > ZnCl2 + H2

    The hydrogen is released in its atomic form and usually recombines shortly thereafter, so that there might be a chance that it migrates into the nickel lattice before that happens. Nickel is not affected by HCl, so it should remain in its original state. Since the reaction is exothermic (156.5 kJ per mol Zn at constant volume) and the gas cannot escape, the reactor will heat up. The reaction rate, and therefore the time that is needed to build the pressure up, can be adjusted by modifying the concentration of the HCl.

    One advantage of this experiment would be that it does not require external heating. Basic calorimetry could be done by comparing the reached temperatures with values from a calibration run, perhaps with a small electric heater inside the reactor. A comparative run without the nickel powder could as well be instructive.

    An alumina vessel should resist the hydrochloric acid, although I am not sure if the same goes for high temperatures. A pressure relief valve and a blast shield are obligatory, and of course one should not forget that escaping hydrogen could catch fire.

    1 g zinc can produce 343 ml H2 at room temperature, so the pressure could become very high. The theoretical maximum should be calculated before starting. I do not know if a high pressure would quench the reaction, though. It is also impossible to predict how much hydrogen will be absorbed by the nickel or by the reactor walls.

    Again: This experiment may be dangerous and is absolutely not suitable for amateurs.

    • Andreas Moraitis

      Slight correction: Nickel reacts with hydrochloric acid, but very slowly, especially if the acid is thinned. In the given case, the zinc should protect the nickel due to its lower electronegativity.

      Design of replicas and changes of reactor A. Parkhomov
      (Inspired by the E-cat) in the laboratory Open Power

      The experimental campaign ITAbetatron, There is also the replication of processes that
      believed to take place in the E-cat, and the study of variants which aim to innalzarne performance such as controllability,
      efficiency etc., by the adoption of specific criteria that inform such experimentation.
      Based on the recent experiments of the Russian scientist Alexander Parkhomov, relationships
      independent on the E-cat, and the campaign began to MFMP, puts the emphasis on the serious problems safety, both in the preparation of reagents that in the execution of the tests.
      In this respect, it is considered to provide the details of the equipment that have been chosen to carry out the campaign, just launched, the results of which will be presented and discussed at the conference ICCF19 of April 2015.
      The experimental set-up is divided into 4 sections, modularly composable:
      1) gas supply, with refillable cylinders of hydrogen adsorbed on metal powders, and cylinders
      Argon, with adjustment of the individual pressures and the possibility of mixing;
      2) room glove-box manipulation in an inert atmosphere, for the loading of reactive species in
      capsules steel interchangeable;
      3) the reaction chamber for housing the reactors, by containing them in an inert atmosphere in a container
      pressurized and very resistant mechanically;
      4) the discharge section, with safety valve, expansion tank and filtered collection of dust in the case
      burst, killing chemical hydrogen.
      Composing subsystems 1), 2) and 4), you get the gaming system of preparation of reagents in security,composing subsystems 1), 3) and 4) is obtained in the reaction system security.
      The reactor consists of a ceramic tube which houses an externally wrapped around resistance Nichrome,presenting internally access to a tube removable and interchangeable housing-samples of stainless steel sealed at the ends by threaded screws sealed with firm-threads in the adhesive, ceramic high temperatures, for containment of reagents.
      This tube is wrapped in tape, ceramic fiber for high temperature, and has a tube ceramic
      Direct contact with the inner ceramic tube, for housing thermocouples.
      The whole is inserted in a copper coil for the cooling water or air, further insulated and
      contained in a stainless steel tube exterior. The device, which forms the group
      reactor-heater-cooler, Is contained in the chamber 3),powered by the subsystem 1) and connected to the subsystem 4).A variac guide sending current, once rectified by a bridge, to the heater, and a power meter records the input power after filtering with a low-pass filter and an isolation transformer.
      The measurements of the thermocouples are recorded by the computer interface.

      The difficulty to operate at the high temperatures involved has made ​​a test for resistance testing
      Thermal apparatus, as well as the dangerousness of the reagents has required the adoption of
      manipulation in an inert atmosphere, with recovery of any dust in totally enclosed system.

    This instructional video shows:

    – the accuracy of temperature measurement of the Williamson Pyrometer, regardless of the apparent emissivity ( or signal strength ). This can be seen by the pyrometer giving basically the same temperature measurement as the kilns K-Type thermocouple regardless of when looking through the portal or with the door open.

    – coils in the kiln appearing darker when they are not actively being driven to the same or higher temperature as the alumina based insulation in the kiln. This can be seen when the kiln door is open and the power has been switch off to the heater coils.

    In the test we can see what happens to the “signal strength” when the same alumina the dog bones were cast from is measured when at temperature in a kiln that is fully at the same temperature, and when it is exposed to cooler air. In both situations the Williamson performs well.

    You can see some relevant screen grabs here:

    The Chan method. This is an old post on the Build E-Cat site, but can be useful. (He claimed a successful replication of E-Cat).

  • Hi all

    At one time, back in the last century, I worked on some experimental electron beam vacuum welders. There has been some mention of a surfeit of electrons being part of LENR (the Rossi Effect). I am given to wonder if a pre-fuelled powder under an electron beam might be an interesting experiment. The vacuum required would be a problem, perhaps powder sealing. The other problems, might be geometry and finally and most worryingly I always have in my head the formulae E= MC^2. I think those trying out such ideas would do well to try them out in a desert or remote island somewhere.

    Kind Regards walker

    • Andreas Moraitis

      Interesting idea, Ian. Maybe one could even use a hydride mixture instead of a preloaded sample. Pressure and obtainable loading ratio could turn out to be problematic, but anyway this might be worth a try.

    []=Project Dog Bone=[]

    In this short instructional UHD clip, we show how to make a heater coil suitable for a dog bone or *GlowStick*. In this case we used a helically grooved metal rod held in the spindle with a drilled end to seat the lathes centre from the tailstock spindle. The video shows winding of Kanthal A1 wire which is a little springy and needs tension applied. At the end of the video you can see the finished winding next to a “fat coil” dog bone.

    For the *GlowStick* winding, a smaller end drilled rod was used with no groove. For these we used some Inconel 600/601 which is easier to wind.

    For those that do not have access to a lathe, it is possible to make small windings like this:

  • Sanjeev

    Yes, its challenging. But all the best !
    Perhaps watching the heat after death is a good way. The active tube will have a different cool down curve than the control one. (Assuming your microwave furnace has a built in thermometer).

  • Sanjeev

    Lenr-Forum user “wishfulThinking” is planning to use microwaves for his replication. A new replicator on the scene.

  • Sanjeev

    bschill – plans for a replication.

    It looks like a new design rather than an exact replication.

  • Sanjeev
  • Obvious

    I was just thinking about the various difficulties in assessing/verifying the heat in replications generally. Perhaps a series of metals (or compounds), arranged by melting point might help in temperature calibrations. Maybe a dog bone could be constructed with a flat side (top) to hold small alumina cups with 1-5 gram “buttons” of various calibration metals. One could pick a short series with melting steps at known values.

    Or use these to confirm extra heat after verifying that a range of these metals cannot be melted at a certain input heat level in dummy tests, them demonstrate them melting in an active run.
