No, Tom, I had not see anyone use the disc
configurations that I used which were "designed" to appear solid (more or less)
to the sonic wave but permit gas flow through them. I have seen discs with
holes used but they permit the sonic FAW wave through as well as the
gas. At least that is my assumption. If you recall the discs looked
like paddle wheels with the blades bent less than 45 deg. The idea was
that it would still look pretty solid to a sound wave but the gas molecules
could find plenty of room to go around the face of the blades and continue the
flow.
I think the idea has sufficient merit to try it one
more time without spinning discs to see what the results would be. Ok,
I've shown you mine now its your turn to show me yours {:>)

Hi Ed,
Yes, I remember your muffler experiment. Let me ask you, is
that something you had seen before? Issues with my
concept was weight, manufacturability, and it being a heat
sink. But in the last few minutes I did what I often do. I
came up with another iteration which deals nicely with those and is so simple
that anybody with welding gear could make one in their shop. It
just looks a little funny.
Tom
