The same is with the Sun. The bumps on the surface we see after 8 min.
The
auroras after a few days.

Sorry S* I did not read this post (I have to solve aome problem with
Google "tree view").

When I talked about ions I do it thinking in electrolytes containing
feee heavy ions, not isolators.

For electrons the electrolytes are like the insulators.

My doubts with "mass" are about radiation of heavy ions with low
electric fields. Larmor analysis shows radiaton of ions must be
various orders of magnitud below radiation of electrons at lower
electric fields intensities because its larger mass. We need higher
electric fields intensities to get accelerations capable of radiating
equivalent power obtained from electrons with lower E fields, then I
believe they are not responsibles of useful possible EM radiation in
our conditions.

Stream of salt water is like a mast made of insulator with its surface
sokaked with the salt water.
It is in state of permanent surface breakdown. So the electrons can flow and
the "mast" works like a metal antenna.

Athough I have built ionic 50 ohms dummy loads with salt and water,
then, I saw it is possible to establish VHF frequencies currents in
such electroytes, however Larmor equation would dismiss (I think)
efficient ions's radiation from it.

Physics books explain EM wave reflections saying low energy EM photons
can transfer its energy to electrons, and they inmediatily return this
energy at the same frequencies (they not become "excited"), then I
think that a possible explanatory mechanism is that radiating charges
in electrolyte be simply the not free electrons (not heavy ions)
vibrations induced by electric field in electrolite.

I do not quite trust in NEC optimistic results I got, because I do not
know if resistivity model includes electrolytic conductors, but this
it is only my ignorance about it, not an sustented opinion.

I have not evidences but I can bet that there are the surface phenomenons.
