I really like your concept!
While experimenting with the parts, i found that in some instances, the transfer beams could build up to large amounts of effects when pointed at each other. In my eyes, this is not a bug, since i didnt get perpetual generation of energy, i just find the amount of stacked media effects a bit distracting:
And when the beams are pointed at parts other than ion antennas, the recoil of the beam starts to push the ship around.
May i suggest, that since these are meant to be energy transfer beams and not weapons fire
that you remove the lines containing "Impulse = value" from "<ModFolder/shots/ion_beam_regulated/ion_beam_regulated.txt>"
That would effectively remove the recoil. Or you add "SourceShipCollisions = false" to "<ModFolder/ion_antenna_small/ion_antenna_small.txt>/Part/Components/BeamEmitter"
Which would make the beam go over the rooftops instead of hitting the source ship (still hits enemy ships)
You don't have to if you don't want to though, these just are suggestions.
I like your mod, Keep up the good work
