Back in the sixties, there was a plasma tweeter on the market (Ioneer, or
something like that, I think.) for a while. It died, apparently. I heard
stories of ozone-induced nausea, bad shocks and even a fire. (Note that I
_do_not_ speak for the veracity of any of those stories: they're _rumors_!)
Whatever the reason, it went away.

In the early seventies, Alan Hill of Albuquerque developed a virtually
distortionless corona/plasma speaker and marketed it in the late seventies.
It was an "upscale" (read: expensive as hell) device, and as far as I'm
aware was a commercial failure. I don't know if he ever sold any of the
things or not. If there's any interest, I can ask him...I need to talk to
him about something else, anyway....

A ham I knew, Howard Meridith w5q-something-or-other, now a silent key, had
a resonant coil of some sort that he drove with a 2 kW amplifier. In AM mode,
that thing developed an eight-inch corona -- corona, hell, it was an electri-
cal _flame_ -- that said whatever you said into the microphone. It's been
years since I've seen that...I musta been about twelve when he showed it to
me...and I can't recall any details on the how and what. Such is life.
