Using dual-resonant Tesla Coils to create non-thermal resonant hydrogen plasma.

[joabel1971]

I am building device that potentially will generate resonant hydrogen plasma & have some suggestions that have not been offered - on how to make a better Tesla Coil (since the question was asked).    In my experiment - I am attempting multiple resonant conditions to create a non-thermal hydrogen plasma that is 100% ionized (a pair of non-flammable, room-temperature ICP jets). 

a.  I started my design with Tesla Patent #512,340 (showing the potential advantages of interleaved cone-coils).  A diagram in the patent appears to be missing (showing a side view).  Only a top view is shown - implying a pancake coil.  However, I have tested helical versions of this coil (without external capacitors) to find resonant conditions for AM electrolysis experiments.  This interleaved method apparently stores 250,000 times as much energy as a 1-wire coil-winding method.   According to the patent, interleaved coils also have the ability to cancel out their own capacitive & inductive reactance at their resonant frequency (based on wire length formula for resonance of the secondary). 

b.  To tune the coil & take advantage of superposition - I am using the rest frequency of hydrogen (1.42 Ghz @ 21 cm) and 6 more 1/4-wave wirelengths multilayered (lowest frequency is 346,778 Khz @ 865.104 meters).  The correct phase between frequencies to create constructive interference has been calculated at 3/2*pi, however, square-wave signaling appears to eliminate this requirement. 

The summation formula is:
f(x) = 8 + ∑ sin((5.291423766936 * 4^n * x) + 3/2 *pi)
n = 7 - 14

This superposition calculation has been mathematically proven with graphing software. 

FR @ 4^14 =   1,420,405,751.  766702882816 Hz   
FR @ 4^13 =      355,101,437.  941675720704 Hz   
FR @ 4^12 =        88,775,359.  485418930176 Hz   
FR @ 4^11 =        22,193,839.  87354732544   Hz   
FR @ 4^10 =          5,548,459.  967838683136 Hz
FR @ 4^9 =            1,387,114.   991959670784 Hz
FR @ 4^8 =              346,778.   747989917696 Hz

c.  To allow the use of 30 volt, 10 amp DC power supplies - I have also added 1/4-length PRIMARIES (in relation to the secondary lengths) & positioned them below the secondaries (not layered, but adjacently below) to try to fix any impedance mismatch.  1/4-wave transformers are documented ways of eliminating impedance mismatch. 

d.  I am signaling the device with a new microcontroller that outputs 54 different frequencies at the same time (1 Hz - 25 Mhz) - called the Parallax Propeller 2.  It is tested.    The 3 highest frequencies will be generated using either Voltage Controlled Oscillators (VCOs) or output signals from a Vector Network Analyzer (NanaVNA-F V2 is capable of 1.42 Ghz).   

e.  I am using a slant angle that causes the slant height of the cone-coils to be equal to the circumference of the cone.   This simplifies calculations in a number of ways.  The slant angle that does this is around 80.842150 degrees (depending on the size of the nozzle hole at the top).

f.  My 3 output nozzles are nested and contain 4 materials - water (to generate steam), hydrogen & graphite, and hydrogen & silica.  Due to the self-organizing properties of complex (dusty) plasma, my overall goal to to create a new material - a graphene/silicene hybrid. 

g.  All non-hydrogen gasses (including ambient air) are being evacuated from the cone coil system using qty. 2 - 8" duct fans. The cones are internally bi-sected with a sheet of stainless steel to create a ducting system.  (1 fan to suck air in - 1 fan to suck air out).

h.  The entire frame is made of 304 stainless steel (non-magnetic & poorly conductive).  The coils are 18 AWG enameled copper for the primary & 30 AWG enameled copper for the secondary.

i.  No capacitors are being used - since the interleaving creates a certain amount of capacitance to reach resonant conditions. 

j.  The highest voltage used is 300 volts at 1 amp for the lowest frequency (since the resistance of the secondary wire is 292 ohms).   Each successive voltage is 1/4 of the prior, but current should remain 1 amp for all superpositioned wires.
