The late Dr. Flanagan had several alternate energy devices/ systems, including the space ion drive invention  that was purchased by US government. I was mostly interested in the communication system using the ETHER and line of sight type. The Neurophone changed audio picked up by microphone to RF that the brain picks up directly, so as the ears are bypassed. There were several different models. Patents were applied but quantity production not done because government  officials said it enhanced ESP abilities and the general public should not have these, and should continue being deaf.

Such devices are made by skillful people themselves, both through contact method (electrodes) and through capacitive coil. Low-power, 5 volt power supply is enough. There are already specialists who encode by frequency modulation therapeutic programs and medicines. I made such devices myself. The result in some cases is amazing, there are times when it does not work.

"Vortex medicine is a new alternative holistic medicine with a holistic approach to treating diseases. It uses the high-energy torsional field of the immaterial human body to treat diseases of the material physical body."

how this immaterial body - torsion (information) field looks like on the photos taken in Kiev in the 90s of the last century.
"torsion" is not a physical name, it's esoteric.

also an example file for modulation in treatment procedures called "colds1".

Also the scheme of the simplest device for bioresonance vortex medicine. The transmitter is a bifilar tesla coil with an inner diameter of 25-30 mm. It is connected in capacitance mode: one wire on the outside, the other on the inside. Important!!! That the natural frequency of the bifilar coil was within 300-350 kHz. The input signal must be processed so that the lower potential does not fall below the value at which the coil's own resonance collapses.

Warning! The circuit is given for comparison with the mode of the circuit from the patent. Personal application is your own responsibility!

I know this master oscillator circuit. Feedback with a phase shifter.
The question is, why three variable resistors, three adjustments ?
What do they give? What do they change ? As usual enough one,
 or nothing at all.

The circuit lacks a switch for three modes with different frequencies. In any case, I made similar ones on a 555 timer.

Theres many applications for what you see in that part of the circuit
But as it pertains to the topic,
I made a short video that i hope helps

yes, as i stated in my video, resistors will perform a similar task
but for the application, analog signals are more suited for the human ear
and also with biotech we always want to use the most energy efficient methods

I made the generator like in that picture. The electric lamp was having used !
Nothing interesting. In addition, this design is used at frequencies of kilohertz, tens of kilohertz.
Doesn't work well at higher frequencies. Every single RC must shift frequency in 60 degrees.
Using three separate adjustments doesn't make sense.  What is frequency  used in Flanagan"s device?

I made a small review of a very interesting technology that is available at your home if you can think and do with your hands:
