Marko Rodin Coil -- 007 Device

The voltage in the capacitor starts to increase.

No and N0,as both are not ideal.
Having resistance enables power to be dissipated as heat,and having no resistance(ideal),means that power cannot be dissipated.

Are you saying that in the examples I have given it is the amplifier's output impedance of .01R and/or the inductor's .1R DC resistance that is somehow determining or limiting the current flow when the square wave driving the inductor transitions between +30 and -30 volts (as opposed to the frequency content and inductance)?

Assuming no DC offset in the amplifier, would using an amplifier with a 10X lower output impedance or a 5mH inductor with a 10X lower DC resistance, or a combination of both, substantially increase the observed current flow during the +30 to -30 volt transition?


The audio power amplifier, within its performance capabilities, is a fair approximation of an ideal voltage source (particularly if we assume zero volts of DC offset).  Similar to an ideal voltage source, the amplifier will source or sink whatever current is required to force the output to be at the selected voltage.  Unlike the ideal voltage source, the audio power amplifier can only sink or source an amount of current that is within its design limits whereas an ideal voltage source can sink or source an infinite amount of current if necessary.

While this discussion is very interesting, isn't anyone concerned that the available materials (pdf, documents and videos) from the Rodin coil proponents all seem to indicate that the claims of "overunity" are based on measurements or calculations of reactive or apparent power output compared to real power input?

TK,

As you already pointed out, we've seen the Irms X Vrms thing and disregard for phase shift/PF before.

Did you look at page 10 of the PDF I posted regarding current probe Russ is using?  The phase shift of the current probe is pretty severe at some of the fundamentals and harmonics he is using.

With regard to the page of data you posted showing a scope capture and power "calculations", where was that info taken from?  Was there a schematic provided for the test/measurement setup?

Where are these "materials" located?

As you stated in your example,the amplifier can be a current sink or source,as it has resistance,and that being the reason it gets hot. In MHs example,all is ideal,and has no resistance,and there for cannot sink or dissipate energy. The stored energy in the inductor is not just !gone! as MH put it,when the voltage polarity is reversed across the circuit-that still has stored energy from the previous applied voltage.That stored energy has to be dissipated,but there is no where for this stored energy to be dissipated,as there is no resistance in the circuit.

Why do you assume that the energy has to be dissipated?
