====================
Years ago I investigated what we call induction arcing.
This when the voltage at a break in a dc current to a
large inductor rises so that it enables an arc to form.
A lot of energy seems to be concentrated in that arc, at
the time (early 90's) I thought there might be a free energy
effect. After all I was melting metal with 150 watts input.
In the study of the power supply it was noticed that a
higher capacitance placed in parrallel with the pulsed DC
from the rectification system would yield both higher voltage
and better arcing. Normally I used about 10 microfarad for the
filter. This was for a 56 Henry air core inductor. Then it
occured to me to try an extremely low value that could
resonate with the 120 hz pulse.
This turned out to be hundreds of times lower , about .03
microfarad. The induction arc then took on an amazing
penetrating laser like action.
One day while playing with this the whole garage started
resonating with a high pitched sound! This was the strangest
experience, the sound seemed so all engulfing as if the
whole garage was vibrating.
Chalk this up as an analomous phenomenon, as we were never
again able to produce this effect which lasted about 5
seconds.
I recall something about the early day of radio when a
singing arc was mentioned. I dont know if this was a high
frequency arc used to make a radio reciever make a certain
auditory frequency or whether the arc itself could emit
musical tones.
Would appreciate any info on this "singing arc" referance.
