STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

[Omnibus]

@All,

As I promised, I'm posting the results obtained with the current probe. First, the setup:

[Omnibus]

These two figures show the OU effect as a function of frequency. The cutoff frequency of 33MHz is arbitrary and is only chosen for convenience of presentation. As seen, up to frequencies around 190kHz all is as expected, no OU. At a wide range of frequencies the underunity seen is severe, one might say.Th OU effect kicks in at about 190kHz, goes through a peculiar maximum and ends at about 1.4MHz after which there's again severe underunity up until about 32MHz is reached. After 32MHz again OU kicks in, increasing until a sharp increase at frequencies around 41MHz.  Notice now the reversal of the sign--the slope of the input energy-time dependence has become negative. This means that electric energy is being returned to the source. That, together with the excess heat makes the device a direct candidate of becoming a self-sustaining device. Of course, further studies are needed to verify this is a real effect and not just some kind of antenna picking up artifact, having in mind that all this occurs in the low band VHF region.

[Omnibus]

Here are also some data showing the reversal of the V-I phase sf As see in the first figure, the current is lagging bed the current, which is as expected for an inductive coil, up to frequencies around 9kHz. After 9kHz we see a reversal--now the current leads the voltage. This may speak of capacitance  kicking in, as @lumen suggested in another context. One may further think, that at 9kHz the purported capacitance becomes equal to the inductance and conditions of resonans are established which may be the reason somehow for the OU effect. Resonance, however, cannot cause OU and rightfully so, as seen earlier, the OU effect pops up much further down the frequency scale--at around 190kHz.

[Omnibus]

It may also be interesting to show the peak to peak value of the current and voltage as a function of frequency. As is seen, a sharp drop in current is observed at low frequencies, the current decrease being what's expected with the increase of frequency. However, at frequencies around 100kHz an unexpected increase with frequency, at the beginning slow and then sharp, is observed where, as said, after 190kHz the OU effect starts to show up.

Have to go now but will continue in a bit.

Again a good job. You also raise a good point on radio waves, in itself that would seem strange as the fields are confined but to get rid of any doubts I suggest you put the setup in a tin foil covered box or something to make sure it's not influenced by MF AM radio waves.
