Alright, I now have the information I wanted on the flame speakers... actually, flame speakers, electrostatic speakers, and the plasma ones everybody is talking about.
A man my "adopted" uncle met owns a pair of the flame speakers. They are powered with a propane bottle to generate the flame (each speaker has a propane bottle), and the flame is placed between two wire mesh screens which are powered with alternating high voltage from the audio source. Because flame is highly ionized and has essentially and infinite bandwidth, all frequencies are clearly projected... the intensity of the high voltage jerking the flame between the two metal screens determines the volume. Since volume is determined by how much air is moved and how fast (frequency(ies))... the output of this flame goes into a resonant echo chamber like an old mans hearing aid- the one with the horn he stuck in his ear, which gathers all the frequencies and focussed them into his ear canal; the idea being to use the properties of the echo chamber to project louder notes.
So, here's my new question: I was told nothing about the practicality or efficiency of these speakers yet. Would the propane here make this whole thing a funny idea?
