Interest in Stan's WFC seems to be at an all time low lately, but many of us have been and are still working in the shadows!
I post as HMS-776 but lost my email and couldn't reset the password here so I'm posting under my other username.
In Stan's early WFC work he made a Spherical Resonant Cavity to study the phenomenon he called 'Resonant Action'. Patents on the Spherical Resonant Cavity were filed as early as 1982.
About the Spherical Resonant Cavity, Stan stated:
"The motion of the gas atoms will pass out of the opening as though they are jet propelled."
"...the resonant cavity causes the water molecule to travel back and forth continuously and at a velocity that increases geometrically."
It's interesting to note that he stated the velocity increases geometrically... from this statement one can assume this system went into a runaway and the only way of slowing it down and controlling it was to "Gate" the circuit.
"This action continues indefinitely and will continue until the applied energy is terminated."

Looking at the dates of the Spherical Resonant Cavity as well as the picture in the WFC News Release # 3 showing his control circuitry we can see he used an autotransformer & his SCR pulsing circuits.
The spherical resonant cavity and its control circuit box is not anywhere in the estate photos?
Who knows where it ended up?
