    I was thinking that the pencil electrode will be pulled upwards with a much greater force if it's made of a ferromagnetic material as essentially it's working like the magnetic core of push/pull solenoids. So perhaps the only bottom…

    Today I tried winding a rather poor 75-turns air coil (improvised from an insulated 2 mm-thick copper wire), and with a ferromagnetic bracket I attempted to reproduce the basic process used in Alexander Parkhomov's "Woodpecker" (see references further…

    I would drop the "consensus" part or change it to something else. The same scientists would also likely have a consensus that Mizuno's device cannot work.

    I did not know about it, thanks. From a very quick read of the paper you uploaded it looks like the authors used standard frequencies (2.45 GHz and 13.56 MHz are common for respectively microwave and RF generators). However I seem to…

    Yep, it is certainly going to be a complex system to tune and characterize.

    The basic driver of this was trying to find a link between the anomalous effects reported in water cavitation systems in LENR (and LENR-like) experiments and the…

    I was almost considering getting one of those cheap PWM DC motor controllers that can be easily found on online stores (see image for an example), but then I realized that they would only allow to adjust the duty cycle.

    I was aware in general terms of the mode of operation of switching power supplies, but I assumed the signal would be stable enough to not show as a strongly measurable effect and it turns out that I was wrong.

    Results vary, but searching…

    My low-cost experimentation on this line of "research" might end up here. I have just repeated the same test with a 12V VRLA battery temporarily borrowed from an uninterruptible power supply and I couldn't reproduce any previously observed noise through…

    Given that the previously observed radio noise seemed to be present mostly at very high frequencies, I tried doing a quick test today by forming and undoing a small temporary 5-turns air coil to the cathode wire while the cell was operating at about 11…

    For what it's worth, compared to the previous electrolysis-spark discharge experiments this one easily overwhelms my AM/FM radio at a close distance at 12 amperes continuous. In previous experiments I could only very rarely get the…

    I have a Dremel, but can only test that next week. In any case, these were cheap no-brand utility knife refills. They were covered from the factory with some kind of oil presumably to prevent oxidation. An initial period of electrolysis…

    Contrarily to earlier testing with an acidic electrolyte, where I deliberately tried to cause spark discharges, the latest electrode arrangement does not use a coil, so I think in general sparks are not very likely to occur here. In some…

    After yesterday's experimental failure, I tried removing the neutral electrode, leaving only the two main ones installed. I then also added more mica sheets to cover most of the inner gap leaving about 2.5cm on the long side of the knife blades from the…

    What is the estimated temperature reached at the surface of the heating element at maximum power?
    (I'm only wondering if it could be working as a hot cathode)

    Unfortunately I don't have those, so I'll have to come up with something else or wait until I can make a list of stuff that I need and get everything at once (not something I'm looking forward to do).

    I don't plan directly using high…

    Here they supposedly measured a flame temperature between 124 and 144 °C, but it's a technical report from a company which sells oxyhydrogen (so-called "HHO") systems:

    I've already read it earlier, but many people on LENR-Forum might have not; thanks for that. It's related to the tests and background of the possible experiments described here, but probably most people won't appreciate the hypothetical link…

    I tried checking out what is the natural frequency of the electrode assembly as shown in the opening post (which is just a provisional arrangement, although it was assembled to be potentially used as it is) by striking with a rigid object as if it was a…

    Where was this suggested?
    Very interesting paper by the way; would deserve its own thread.
