It's partially related to electrolytic plasma experiments that I and others have been recently exploring, but since some fundamental and defining differences exist from the original subject and the paper itself deserves careful analysis and commentary, I thought it would be more useful to have a dedicated thread about it (and about experiments to replicate the observations)

Abstract: A description of a system where plasma electrolysis was studied under different modes of reactor operation (immersion in the electrolyte, light touch, small gap, different polarity of the central electrode, different capacitance of the capacitor, single discharge or continuous operation) is given. The method of determining the ratio of heat released to the electricity absorbed by the reactor is described. A value greater than 100% is found only when the anode does not touch the electrolyte but is located at a small distance from it. In other cases, the heat is about the same as or slightly less than the electricity consumed. The results of the analysis of the elemental composition of the electrolyte before and after plasma electrolysis are presented.
As the central electrode (anode, i.e. positive electrode) is at a small distance above the surface and voltages of 1200V are used together with a 50 µF capacitor (typically), the discharges produced which generate anomalous results are quite energetic and have the nature of sparks (roughly 50–100 µs pulses peaking up to 1000A).
Current and voltage, as well as electrolyte temperature seem to be carefully recorded with an USB oscilloscope and data logger, which I identified as:
Links to short videos are also included in the paper, but last time I checked there were not any of the energetic sparks yet.
