Please forgive my persistence on this topic of wireless electricity and
diaphragm-less speakers
Can electricity flow through air w/out sparking? I guess that it could
provided that the voltage is high-enough to break through the
resistance of air AND the wattage is low-enough that it does not ionize
or incandesce the air. Am I right? If so, could this high-voltage,
low-wattage electricity be used to reproduce intelligent sound [e.g.
music, speech, etc.] in the air itself?
Once again I apologize if my posts seem redundant.
Thanks,

Yes, electricity can flow through the air. But not in any way that
really matters. It's more like a leak than a flow. There's always some
ions floating around, and humidity makes it leak faster. Comb your hair
and pick up small bits of paper with your comb, and see how long it
takes the paper to fall. If electricity didn't leak through the air,
the paper would stay stuck.
This is different from a spark. When the air sparks, the resistance
goes down to basically zero and huge currents can flow. Without the
spark, it will only leak. Slowly.
