Experimental re-examination of the basic physical properties of the Tesla coil does not confirm the commonly held notions that it radiates "electromagnetic field energy", or that its loosely termed "electrostatic radiation field" is in any way mediated by ions formed as a consequence of the ionizing properties of the said electromagnetic radiation. Formally, we demonstrate how the Tesla coil is neither a source of ionizing photons (since it fails to discharge a positively charged electroscope, inside - or outside - of its electric or 'electrostatic' field), nor a source of HFOT or LFOT photons, including thermal ones (since it fails to trigger photoelectric cells and its diathermic effect can be shown to be an indirect one). It is also not a source of either negative or positive ions, given that it can bipolarize a doped full wave divider. Yet, its 'electrostatic field' charges most metallic (ungrounded) surfaces positively. To explore further the nature of the Tesla waves, we tested the effect of the Tesla coil output both with a proportional chamber and with a simple plate antenna connected to a radiation ratemeter: whereas, like ionizing and HFOT photons, Tesla waves triggered the proportional chamber, unlike either, and unlike any other, type of "electromagnetic radiation", Tesla waves alone were capable of triggering the ratemeter via the plate antenna, even at substantial distances.

Taken together, these results suggest that there is a complex process of conversion of energy at work in these induction coils. The pulsed input to the primary coil induces in the space of the closely coupled secondary a conversion of the local aether energy into electric form. Aether wave energy is tapped by the capacito-inductive properties of the secondary coil to yield resonant, synchronized, superimposed, but distinct 'electric' (electrocapacitative) and 'magnetic' (magnetoinductive) waves. These wave functions properly constitute the massfree radiative field energy emitted by the coil, but they also induce or assemble, within the secondary, an alternate current of massbound charges, or electrons. In turn, this alternate current of electrons in the secondary couples its own 'magnetic' field to the electrocapacitative waves of the coil, to yield a proximal field effect which is responsible for drawing valence and conduction charge from metallic bodies. Beyond the limit of this proximal massbound field effect, the radiated (distal) field of what is known as 'Tesla waves' is composed solely of the 'electric' and 'magnetic' massfree waves radiated from the coil, and is only able to draw charges from the conduction band of metallic bodies. There are therefore quite distinct field effects of Tesla coils. Unfortunately, the proximal field energy has been confusedly assimilated to a "DC or electrostatic field", just as the distal field has been confusedly assimilated to an "AC electromagnetic field". But both fields possess "AC characteristics" and their real difference stems from the fact that one is both proximal and distal, and composed of primary massfree charges, while the other is only proximal, and the effect of the secondary flux of massbound charges. All happens as if the these coils synthesized two different kinds of electric fields, one proximal and massbound, and the other massfree and responsible for all distal effects. It is the massfree electric field that serves as the conduit for the massbound electric field, since only the former exists both proximally and distally, and thus all observable distal effects are due to it - such as the observed acceleration of leakage rates in electroscopes placed at greater distances from the coil. Conversely, it is the induced massbound charge field that is responsible for the observed spontaneous positive charging of the electroscope in the proximity of the coil, but since the radiated electric energy is not an ionizing one, nor does it consist of ion emission, the observed proximal monopolar (positive) charging of metal objects depends solely on the metallic nature of the targeted bodies, not upon any supposed "DC characteristic of an electrostatic field" output by the coil. In a parallel fashion, the primary massfree charge field is no less electrical than the proximal field - and thus fully undeserving of the epithet "electromagnetic".

We can only speak of production of photons or the presence of electromagnetic energy when the primary superimposition of the two synchronous wave functions of the massfree energy field is resolved, at the surface of the metallic bodies that it is emitted from or strikes, to yield the "characteristic electromagnetic" or photonic frequency of the coil in the form of damped waves. Light, and also heat, are therefore indirect effects of Tesla waves, mere secondary emissions from metallic bodies exposed to Tesla radiation. The true "electromagnetic AC component "must therefore be understood as the secondary mechanical result of resolving the superimposition of Tesla waves. From this vantage point, the so-called 'electrostatic' and 'electromagnetic' fields of the Tesla coil cannot be thought of in the traditional manner where the former is the result of the latter, as mediated by ionization, and where the latter alone constitutes the primary emission. There is neither an electrostatic DC field nor an AC electromagnetic field (let alone an ionizing one), and we demonstrate this fact experimentally; both electrostatic and photonic fields are secondary effects resulting from the interaction of metallic matter with resonant 'electric' and 'magnetic' waves, such that the superimposition of these waves is subsequently resolved either to charge that matter or to induce it to emit light and heat.

Finally, basic aetherometric analysis formally demonstrates how the aether wave functions, whether formed capacitatively or inductively, are not limited at all by the photon limit wavespeed c, and thus cannot be thought of, in any way, as subfunctions of an "electromagnetic" wave that propagates transversely to the direction of its forward motion. Here, the critical element of the analysis is the electric frequency term which, in the "vacuum state", can be seen to exceed the blackbody radiation frequency limit   , thus indicating that the aether continuum may not be limited, in its upper end, by the blackbody upper limit. This constatation is what originally led us to the discovery of the aether electric spectra, to be presented in companion reports.
