A battery of one thousand energy transmitters provides the initial momentum for the seraphic departure. 
The Constellation Fathers dispached a resolution supporting Van against Lucifer's rebellion but the verdict failed to reach Van because the order had been blocked in a relay energy transmitter due to Urantia's isolation. Energy transmitters can receive and transmit intelligence, but they cannot initiate communication.  When energy is to be diverted to a new circuit, the transmitters deploy themselves in a line along the desired energy path.  These beings, together with the energy transformers, are indispensable to mortals on nonbreathing planets.  They are living superconductors; they can actually induce an increased energy flow in the desired direction and augment feeble energies.  They provide the emergency lines of communication in the local systems and on the individual planets.  They can render a distant scene “visible” as well as a distant sound “audible.”. 
They appear in Uversa personality register.  They are one of types of Master Physical Controller.  They seem fully able to receive our communications but quite powerless to make response.  They are totally automatic and mechanical in response to the impulses of their superiors and in reaction; they are nonpersonal.
