Freethinker’s New LENR Testbed (Video)

I think that people interested in LENR replication will find the following video from Freethinker quite interesting. Freethinker is, I believe Swedish, and has been getting quite serious about replicating dogbone-type devices.

This video shows his efforts to insulate his reactor, to help prevent burnout of his wires by reducing the amount of power needed to maintain high temperatures. If you look at the last part of the video you’ll see that his system of insulation using aluminum oxide bricks seems to work very well.

He has a very nice setup and I look forward to seeing how his experiments progress.

    Very nice video Freethinker! Thanks for sharing this. I have always wondered why others did not insulate. Maybe it is because if LENR starts than so much energy is being generated that the reactor will overheat. Was that a thought that also crossed your mind? I know that Parkhomov also used some kind of insulation.
    You have started testing. Any results yet?

    • Freethinker

      The insulation was suggested to me at lenr-forum by commenters there. I new of others doing it, but I though I travel the road without insulation. But reality bites, and choosing from complex transforming of power, multiple coils and insulation, I chose insulation. It was a wise choice I think. I use almost half the current otherwise used at my operational target, 850C outer shell temperature. I think that having a less aggressive control of current (rapid on/off) and lower current will make my 0.7mm wires live longer. The stress is so much lesser, even if the temperature is as high as without the insulation.

      I have done 1 run with active reactor. I have not written all up yet, but I found no event of distinct anomalous heat, but a few other oddities and interesting things. There are two docs:

        I am impressed with your work Freethinker. You seem to have most things in hand, perhaps with the exception of the heating coil. Do you ‘treat’ the Kanthal wire before usage in accordance with the Kanthal guidlines? For high temperatures thicker wires are adviced. High currents may also trigger LENR.
        For further test I would suggest you to add some iron powder (1/2 of nickel quantity) and if that does not work, soaking of the nickel in hydrogen atmosphere (first evacuate 1-2 mBar, then put it under H2 of at least 2 bar during a week).
        Good Luck, Gerard

          The only treatment I do is annealing the coil after being wired. I am using it – or rather abusing – a bit off the chart as compared to the handbook of Kanthal, but I think this will work still when using the insulated setup. I have a new test reactor build with a 1mm diam wire coil, to awaiting a time slot on the bed. That is my next step if after all the 0.7 fail me when doing active runs in the insulated test bed.

          Your suggestion of hydrogenation seem out of character from what is known from Parkhomov and Lugano. At any rate, what you suggest is achieved in a different way when you have a good pressure seal on your reactor tube, like I show in my docs linked in above. With a hefty partial pressure of some 50 bar of H2, maintaining that for hours, would hydrogenate. Of course, I have not done this a week, but one could imagine a test with doing the H2 release from the LAH, maintain the reactor at some 200C (or lower, the H2 is there) and then leave it for a week. You would have some 10 bars or so, a very high H2 partial pressure. Actuall, this last Monday, had not my reactor been too damaged (see ) I would actually be in a situation that you described. Pitty. That would have been interesting.

    Great work Freethinker! Looking forward to hearing more progress reports.

  • Freethinker

    🙂 that would be something.

      LENR needs a very tiny little little small amount of radioactive material to start the reaction, this is Rossi Secret. That’s why he is callng his new CAT with name Mcurie…

      • Freethinker

        What brings you to this conclusion?

      • Obvious

        “To add radioactive material to the charge would annichilate all the certifications on the spot and would make unsellable all our production. Not really a good idea, Sir!”

    I think alternating high currents would help with pulse type shapes, don’t smooth them out with timmer circuit to cut noise. Use simple power meter to record input of noisy circuit – they have high speed current & voltage measurements built in to give good power calculated input record. You may be able to tape the average power input of noisy circuit from point in meter display circuit.

    Noise may be just what you need, not knowing exactly what the resonance coupling to (ssm) LENR is? Again similar power source to Lugano. Would be nice to have frequency content but your sample rates on amp/volts are not fast enough, need for actual power meter like in the PCE 830! If you slow down your power input to sinusoidal to bet better measurement, you may be loosing your ability to initiate & control (ssm) LENR process.

    note current pulses in right half of PCE 389 graph below & frequency content to the right. Both Rossi & Parkhomov used noisy TRIAC source with alternating current profile. Think this may be secret to starting local LENR at the Ni interface with the conduction electrons as well as those left on surface by ionization of the H ions trapped in the metal lattice. This would provide the surface plasmon politron field necessary to generate ultra low momentum neutrons for the power generating isotope chain they feed.

      Thanks Mr Rovnak for the feedback.

      Yes. Rossi has been known to use noise triacs but also better control. Lugano was a commercial 3 phase control box, of slightly better stature than a simple triac, I think., I use a SSR, which in normal more of operation, shuts on and off, and the current, and if between 0 and 100% duty it block part of the phase. I’d say that it would well suffice for noisiness. You may be right that the sampling rate is insufficient for my voltage and current to get a very good measurement on the power, but it will have to suffice for the moment. I am not convinced that it is the noise in the current that triggers the effect, it is more what it does to the property it controls, ie,. the temperature. Right now I am not looking into buy more equipment, but rather see what I can achieve with what I have.

        Great setup I wish you luck!

        I have a suggestion you may want to try in the future if the current round of tests do not bear fruit. Rossi’s theory that has been prepublished appears to suggest that the reaction may be due to a fission/fusion reaction involving Li7 and H. Other researchers have suggested that this may be possible in a partial vacuum when Li and H ions are excited by an electrical arc. If electrical contacts were allowed to pass into the interior on either side of the reactor tube a high voltage could be passed between them to possibly cause similar conditions when the temperature is high enough to boil the Li. The high voltage could be supplied by repurposing the power components of a TASER or other off the shelf high voltage low power equipment like lighting ballasts.
