Corona discharge. Biefeld-Brown effect. Ionocraft. These 3 phenomena names say that the noise of a honeycomb on a high voltage cable is produced by electrons to collide with the air. Then there is breeze. The breeze causes fan blades not electrons. How a round particle emits breeze? In a high voltage cable. The sound of the breeze is not equal to the of a honeycomb. CONCLUSION Blue theories that I mentioned above are wrong.
