I think that there should be no strict polarization between "believers" and "scientists" within this group if we separated facts from interpretations.

I have a question relating to "longitudinal electromagnetic waves". Regarding
the magnetic field surrounding power lines, this field is expanding and contracting 50 times per second, since the current wave associated with this field has a frequency of 50Hz. A person near a power line is therefore exposed to a magnetic field which expands and contracts in all directions around the power line. Although strictly speaking, this is a 'field' and is seemingly connected to the power line, isn't a person effectively under the influence of something like a longitudinal magnetic wave when standing near a power line? The field, by definition, does not behave like a wave, however I fail to see how the impact of this field on a person standing near a power line is drastically different to that of a longitudinal wave, which presumably might be radiated from this field under certain conditions (in a similar manner to the way that a transverse electromagnetic wave is radiated from a transmitter). Presumably this is like being in the near field region of a form of transmitter (and I know the characteristics here are different from those in the far field region, however I don't know exactly how different or whether some completely different phenomenon is observed). Furthermore, an electric field also exists around a power line, which is associated with the voltage wave, and this field also surrounds the power line and is expanding and contracting at the same rate as the magnetic field. Could this not explain how people could be experiencing the effects that would result from being exposed to a longitudinal electromagnetic 'wave', without there actually being a wave as such, but rather a concurrent pair of alternating fields? Like most people, I find this topic very confusing and I do not profess to understand what Tesla or anyone else might have meant by longitudinal electromagnetic waves, however I think I understand what distinguishes a longitudinal wave from a transverse wave. I would appreciate it if someone with a better understanding of these things could tell me where my reasoning is flawed. On a similar topic, according to my very limited understanding of radiation transmitters, just after a quarter way through each cycle, i.e. after the magnetic field around a conductor has reached it's maximum strength and begins to decay, a portion of the energy carried by the field detaches from the wave and is radiated to the environment (this phenomenon is presumably responsible for a proportion of the significant amount of energy lost during power transmission). I am not sure about the nature of this 'detached' energy, apart from the assumption that it is radiated as some form of wave/s, which could either be transverse (and I imagine some or all of the energy is in this form), longitudinal or a combination of both. Again, if someone can clarify any of this it would be a great help.
