Is there any information on flame ionization or a flame speaker?
Using Iowa State University's online journal index, the only reference I findto "flame ionization" is "flame ionization detectors"; for example,
an article entitled "Flame ionization detector response factors for
paint solvents: measuring emissions of volatile organic compounds."
Is that the sort of thing you are interested in? If not, can you give more
For "flame speaker", I found this on the online Readers' Guide Abstracts:
"Experiment with plasma acoustics", by John Iovine, in the magazine
Popular Electronics, vol. 9 (Oct. 1992) p. 37-8. The Readers' Guide says
"As demonstrated in experiments 20 years ago, an audio speaker
can be created from a high temperature plasma. The manner
in which to duplicate the plasma acoustic phenomenon at low
temperatures, using a butane or propane flame seeded with
potassium nitrate, is depicted and described."
