    I'm determining that the material is melting from the small shiny ball that forms at the tip. This is the 1 mm mild steel wire cathode (paper clip).



    It has somewhat become brown from oxidation but so far wear hasn't been too severe and I…

    • It seems easier to cause the AC or reverse DC effect with a higher current density. This can be achieved with thinner, more conductive wires like for example the 0.55 mm copper cathode I used earlier, or by

    • I increased the surface area of the anode, which I thought should give a stronger reaction. The previous anode was cleaned with 180 grit sandpaper.

    Here's some more:
    • I tried using a transistor radio connected to a PC as a sort of spectrum analyzer. It appears there is a noisy carrier signal from the plasma at roughly 700 Hz (depending on reaction conditions) that is best observed at 160 KHz on the AM

    I further thinned the copper wire to a diameter of 0.55 mm. The reaction now starts very easily but it’s also very noisy. It mostly emits a green-blue plasma when current draw is the lowest. Cathode wear still very limited.


    For some reason current draw…

    Earlier I did a very crude calculation of how much heat could have gone into the jar using a food thermometer (range -45~230 °C), and from the temperature rise and the time elapsed in one test I came up with about 5 watts, in another 11 watts: so it can…

    As I kept testing, a reaction very similar to what has been observed by others could eventually be produced. Just barely touching the water surface with the wire would immediately cause the cathode (in reality a repurposed paper clip) to become…

    I made another test, this time turning off the lights. The electrolyte solution getting more concentrated and warmer probably contributed to making the reaction more easily observable and to have a more continuous nature, although it is still apparently…

    I finally got the high voltage DC-DC boost converter. It's tiny. I has 1x 35V 470µF and 2x 400V 10µF capacitors.

    It looks almost exactly like that one, but I'm getting it from a different store. This one is more similar, it even has a fan output: https://www.amazon.com/Adjusta…Efficiency/dp/B0817QZ7DK/

    Worth pointing out that they use 20 µs-long square pulses at 50 Hz at a current up to 1A/cm2, it's not a continuous low-current glow plasma.

    I think it could be interesting to measure with an oscilloscope the signal from the electrodes while the plasma reaction is occurring.

    Here's a hypothesis on the reaction observed.

    The simulation assumes there's a small (inherent) inductance in the circuit. If the cathode is too much immersed (the resistor on the right/"Load"), the capacitors do not…
