I just spent a few days on the Northern California coast and the only thing that could improve on that experience would be a great interview like this.
This video was a treat to watch. Thank you, Nelson, for sharing your time, talents and efforts for those of us who follow you.
I would have loved to hear your see-through speakers.
My personal take is that what you created was a push-pull plasma speaker.
In the 1970s, Hill Plasmatronics made a system with conventional cone drivers and a plasma tweeter that was purported to be flat to 100kHz. Hill's unique twist was to leak a small amount of helium into the plasma arc to mitigate ozone production. Hill's tweeter was driven direct by a tube amp much as Acoustat made a tube direct drive electrostat amplifier.
Magnat was another company who made a plasma tweeter.
As far as I know, neither Hill's tweeter nor Magnat's tweeter were push-pull.
Push-pull is the way to go. In theory, a push pull speaker has zero distortion. I did a derivation of the force on a push pull electrostat diaphragm for a senior paper in EE school.

Nelson's hair, mustache and beard are all white, but his eyebrows appear much younger. Why is that?
😕

Amusing and interesting story. Thanks Mr. Pass !
Next interview about actual FW trends in audio design fresh ideas and the near future experiments?
Oh the workbench on the video show are unusually clean 😀

old eyebrows burned in some testing ,so these are new ones
what else?
You may be right. Eyebrows work as well as a lightning rod when it comes to attracting small workbench fires.

I remember Nelson talking about the "ion cloud loudspeaker" in the early days of the forum. He even mentioned borrowing shoes for the photo session. Here it is:

Great interview, look forward to the remaining series of interviews.
Thanks mr Pass and mr Guttenberg.

By the time this series is done, there will be about 15,000 documented cases of "resistor envy".
Wow, I always knew, that papa must be cool guy, but he is even more cool in person🙂 Looking forward for the rest!
I'm attracted to plasma-based speakers since I've read about Hill's Plasmatronics. I didn't knew about this Nelson's invention, so I'm really impressed.
I wish I could ever listen to something like this.
