Ron, I still get emails about that microphone after all these years. Another researcher has taken it a step further and developed a flame triode.

"Neil Styner shows how to make a working triode from with an alcohol flame, and no vacuum. He observed a power gain of 60x."

Hello Dave,
I've been to his website before. He's got a lot of simple, interesting and low cost projects that one can construct.
One in particular is placing a drop of saltwater on a piece aluminum and listening to its audio output.
I always meant to try that as a sound source for EVP's.
