ESTC 2022 – Vector Network Analysis & Golden-Ratio/Fractal-Fern Plasma Discharges
At the 2022 Energy, Science, and Technology conference[1] in Spokane USA, AMInnovations gave an extensive and detailed presentation on Advanced Measurements Techniques for Tesla Coils, which included a two-part demonstration on the live analysis of a 2-coil Tesla transformer, and a live demonstration of the Golden-Ratio/Fractal-Fern discharge for the first time since its discovery by Eric Dollard in 1978. This was the first ESTC conference that AMInnovations could attend since 2019 due to the travel restrictions from the UK to the USA resulting from the global Covid pandemic. The full official ESTC video presentation and demonstrations, over 4 hours in total, can be purchased directly from A & P Electronic Media[2] here, and a preview of this presentation is shown below. The AMInnovations presentation in pdf format as presented at the conference can be downloaded here. The Tesla transformer used in both demonstrations is the original Golden-Ratio/Fractal-Fern Discharge Coil from the Wheelwork of Nature series, first analysed using the vector network analyser to reveal the ac small signal input impedance Z11, and then driven using a high-power 2.5kW Class-C Armstrong auto-tune power oscillator. This demonstration shows for the first time since Eric Dollard’s demonstration in 1978, the Golden-Ratio/Fractal-Fern Discharge showing the underlying natural order and organisation of electricity, as part of this fascinating electrical phenomena ...

Telluric Transference of Electric Power – MF Band 110 Miles
In this field experiment telluric transference of electric power is tested in the medium frequency band (MF) at 1860kc over 110 miles. This is the final experiment for now in this series which uses a two-coil TMT (Tesla's magnifying transformer) system where the transmitter and receiver are constructed with a primary and secondary coil. A new series of telluric experiments will be undertaken using a three-coil system where the TMT coils have a primary, secondary, and extra coil. With the two-coil system at 110 miles, and the ground electrode in the sea, no signal could be detected even when using a portable spectrum analyser with sensitivity down to -110dBm. In the overall series on telluric transference of electric power, the longest distance where a signal could be detected was at 27 miles in a natural lake, and where both radio and telluric-wave components could be measured as contributing to the received signal. Beyond this distance no further signal could be received, using the same TMT system in two very different coastal regions in the UK, at 70 miles on the south coast, and at 110 miles on the east coast. At up to 600W of input power at the transmitter, and a range of variations at the receiver, including with increased magnetic coupling between primary and secondary, no component signal was detected at 1860kc. Other signals could be received from transmitters in the surrounding region forming a control test that the receiver system was working correctly ... Read post
Telluric Transference of Electric Power – MF Band 27-70 Miles
This experimental post is a follow on from the field-work reported so far in Telluric Transference of Electric Power - MF Band 2-8 Miles and Transference of Electric Power – Single Wire vs Telluric. In this new experiment the same TMT apparatus and generator is used at 1.86 Mc and 400W of transmit power, and the telluric transmission medium is extended into the far-field region at 27 and 70 mile field locations from the TX coil. At the 27 mile location a natural lake was used as the telluric ground connection for the RX coil, and the transmitted signal could just be received, and was shown to result from the combination of a telluric-wave component through the ground, and a radio-wave component above the ground. At the 70 mile location the sea was used as the telluric ground connection, but despite many different combinations of configuration, tuning, measurements, and instruments, the transmitted signal could not be received either through the telluric-wave or the radio-wave. The dominant transmission mode in these experiments appears to be Transverse Electromagnetic (TEM), and it is conjectured that in the more distant far-field a three coil TMT arrangement using Tesla's extra coil may be necessary to "pull" or "draw" the transmitted signal through the coherent cavity via the Longitudinal Magneto-Dielectric (LMD) transmission mode ...

Telluric Transference of Electric Power – Brookmans Park AM Radio Transmitter
In this post we continue to explore telluric transference of electric power, by using a Tesla transformer receiver 300 metres from Brookmans Park AM Radio Transmitter. The radio transmitter broadcasts four stations in the medium frequency band (MF) in the south-east of England, and is one of the most powerful AM broadcast transmitters in the United Kingdom, nominally rated at 150kW @ 909kc, and 400kW @ 1089kc, along with two other higher frequencies. A specifically designed and tuned Tesla transformer receiver, which can be tuned both at 909kc and 1089kc for both the series and parallel resonant modes, is used to receive power from the transmitting station, both through the normal transverse radio-wave above the ground, and through the telluric-wave under the ground. This telluric experiment is very similar to the crystal radio initiative (CRI) originally proposed by Eric Dollard, where a Tesla transformer was to be used to power a 100W light bulb using power transferred through the ground from a broadcast AM radio transmitter. The CRI required specific design of the receiving Tesla coil and ground system, optimised for receiving power from the telluric wave. In this experiment we demonstrate a Tesla transformer that receives ~55mW of power combined in the radio and telluric wave, using a very good ground system, and in very close proximity, around one wavelength, to the radio transmitter ...

Telluric Transference of Electric Power – MF Band 2-8 Miles
This experimental post is a follow-on from the Telluric experiment presented in Transference of Electric Power – Single Wire vs Telluric. In that previous experiment a Tesla Magnifying Transformer (TMT) apparatus, consisting of TX and RX cylindrical Tesla coils, were connected together via a 18m point-to-point telluric transmission medium, and with ground connection cables 26m in total between TX and RX secondary coils. In the medium-frequency band (MF) at 1.86Mc, in the mid-field region, 500W input power to the TX coil generated ~ 80mW of output power at the RX coil, from a combination of the telluric-wave and radio-wave. In this new experiment the same TMT apparatus and generator is used, and the telluric transmission medium is extended into the close far-field region at 2 and 8 mile field locations from the TX coil. In both locations natural water features were used as the telluric ground connection for the RX coil, and the transmitted signal could be clearly received, and was shown to result from the combination of a telluric-wave component through the ground, and a radio-wave component above ground. It is conjectured that at the 2 mile location the longitudinal magneto-dielectric (LMD) transmission mode was dominant in the telluric cavity between TX and RX, and the transverse electromagnetic (TEM) mode was dominant at the 8 mile location ...

Transference of Electric Power – Single Wire vs Telluric
In this new experiment on transference of electric power a comparison is made between power transfer through a single wire and through a telluric transmission medium, using a cylindrical Tesla magnifying transformer (TMT) apparatus. The TMT apparatus and linear generator is the same used in the High-Efficiency Transference of Electric Power series both over 1.5m and 11m, and these new experiments are a continuation on those previously reported. This experiment is also the first in a new series on telluric transmission of electric power, and whilst I have experimented with telluric transmission over the years, none of this fascinating area of Tesla research has yet been reported here on the website. One of the pictures in the main slider at the head of this website shown here, shows telluric reception experiments made in 2017 at the upper parallel mode of a nominally 2Mc, 160m amateur band, flat coil. In the experiment reported in this post, the TMT transmitter and receiver are housed in different buildings of the lab, and can be connected by a 30m single wire, or a telluric channel ~18m point-to-point between the two ground systems, and 26m in total length including the cables. There is no special consideration of the ground/earth/soil between the two buildings, although the transmitter ground system used is specifically designed and constructed to provide a low impedance connection to ground ...

The Wheelwork of Nature – Vibration, Frequency, and Discharge Form
In this follow up experiment in the Wheelwork of Nature series we take a look at vibration, frequency, and discharge form that results from a set of Tesla coils designed to cover an operating frequency range between 300kc and 4Mc. If you have not done so already I recommend reading or reviewing the first experiment in this series The Wheelwork of Nature - Fractal "Fern" Discharges, which will set the basis for this current experiment. In the original experiment a range of experimental variations were tested in order to identify the origin of the fractal "Fern" discharge form, which is a distinct and significant departure from the discharge form normally observed in Tesla coils constructed using a basic standard design format, and constructed with readily available materials and processes. Variations to the experiment included, changing the matching and tuning of the Tesla coil, the excited resonant mode, the generator waveform, the type of vacuum tube used as a generator, and a top-load on the Tesla coil. The only significant variation to the discharge form was noted between the upper and lower parallel resonant modes of the Tesla coil, and hence it was concluded that frequency, or more correctly vibration, of the Tesla secondary coil was key to the nature and form of the fractal "fern" discharge ...

Tube Power Supply – High Voltage & Plate
In this second post on the Tube Power Supply series I present a complete design and implementation of a high voltage (HV) unit suitable for use as a high-power plate supply, and also as a general purpose high-tension source for a wide range of experiments in electricity. I use this unit extensively in my own day-to-day research for experiments in the displacement and transference of electric power. The 5kW high voltage and plate supply is based around three heavy-duty industrial 1.8kVA microwave oven transformers which can easily be inter-connected in a range of different parallel and series configurations. The transformers can be easily combined with different output stages including a bridge rectifier, level shifter (doubler), and a high voltage discharge unit, which are all incorporated into the complete housing of the supply. The complete high voltage supply is housed in a traditional varnished wooden enclosure and is designed to fit together with the other supply components in the tube power supply series ... Read post
The Wheelwork of Nature – The Golden Ratio Discharge
Sooner or later research into the underlying nature and principles of electricity must inevitably lead to those larger philosophical and esoteric questions surrounding the origin and purpose of life, its mechanisms that constitute the wheelwork of nature, and our purpose and part to play as very small cogs in this grand design. I have in previous posts started to tentatively touch-on and develop my own current understanding of the wheelwork of nature through ideas, designs, experiments, and conjectures regarding displacement and transference of electric power. This post is the first in a sequence looking at experiments in electricity which reveal or suggest clues about this underlying wheelwork, with the associated phenomena and results, their possible origin and purpose, and how we may form a synchronicity with this wheelwork, and hence benefit from a journey that increases our knowledge and awareness of our-self and that of the great mystery or grand design. This first post in the series looks at the wheelwork of nature - Golden Ratio or Fractal "Fern" Discharge experiment, along with observations, measurements, and interpretation ... Read post
Tube Power Supply – Heater, Grid & Screen
In research using Tesla coils it is inevitable that sooner or later a vacuum tube power supply will become a necessary and invaluable addition to the laboratory equipment. Vacuum tubes when correctly setup and operated are a robust and high power solution to driving Tesla coils from very low frequencies, and to well into the HF frequency band. Most of my experiments are conducted in the 160m amateur band with a centre frequency around 2Mc, and with tuning that can go down as low as 500kc, and up to almost 4Mc. A vacuum tube generator that can be flexibly configured to drive different configurations and types of tubes to power levels over 1kW, and even up to as high as 5kW, opens the door to many fascinating and unusual electrical phenomena, that can be observed and measured using Tesla coils driven at higher powers and higher frequencies. This post is the first in a sequence to look at my own tube power supply, designed specifically with rapid prototyping and Tesla coil research in mind, and is the product of using vacuum tubes of various different types and configurations in my research over the years ...

Cylindrical Coil Transmission Gain – TC S21
In this post the cylindrical coil transmission gain S21 is explored using the DG8SAQ vector network analyser. The small signal ac input impedance Z11 has been explored and presented extensively for both flat and cylindrical Tesla coils, and the transmission gain study in this experimental post continues the small signal analysis of this type of Tesla coil. The S21 characteristics show that the Tesla coil has its lowest insertion loss at the fundamental series resonant frequency, and its highest loss at a parallel mode. The series resonant mode remains relatively stable with changing primary tuning characteristics such as number of turns, and variations in the primary tuning capacitor. However, the parallel mode shows strong dependence on both the primary turns and primary tuning capacitor ... Read post
High-Efficiency Transference of Electric Power – 11m Single Wire
In this second part on high efficiency transference of electric power, we take a look at the characteristics and power efficiency of a cylindrical coil TMT system where the transmitter and receiver coils are spaced further apart in the mid-field region. In this experiment a single wire transmission medium 11m long is used to separate the coils into different rooms at the laboratory, and a remote camera is used to observe the power at the receiver load measured by an RF wattmeter. Transference of electric power over 11m, and the characteristics of a TMT system coupled by the LMD mode at this distance, is shown to be remarkably different from the close mid-field region, and requires a very different setup and configuration of the experimental apparatus in order to optimise the efficiency of power transfer up to 96% ...

High-Efficiency Transference of Electric Power
In this post we take a preliminary experimental look at the transference of electric power using a cylindrical coil TC and TMT, energised using a linear amplifier generator, and also the high power transfer efficiency that can be achieved in a properly matched system. The setup, tuning, and matching of the linear amplifier is covered in detail in the video experiment where a 500W incandescent lamp can be fully illuminated at power transfer efficiencies over 99% in the close mid-field region. The power is shown to be transferred to the receiver through a single wire between the transmitter and receiver coil through the longitudinal magneto-dielectric mode, and not through transverse electromagnetic radiation or through direct transformer induction. This high-efficiency, very low-loss transference of electric power is possible as the dielectric and magnetic fields of induction are contained around the single wire ... Read post
Cylindrical Coil Input Impedance – TC and TMT Z11
In the first part of this post we look at the small signal ac input impedance Z11 for a cylindrical Tesla coil, and then two coils electrically connected together by a single wire transmission medium to form a TMT system in the near-field to close mid-field region. This TMT system is suitable for studying transference of electric power as a small-scale investigation of Tesla's wireless power[1], where the single wire transmission medium between the transmit and receive coils replaces the Telluric connection between the two grounded and spatially separated secondary coils. In the second part of this post we go on to use the measured Z11 to take a detailed look at the matching requirements for different types of generators to the cylindrical coil system, and the advantages and limitations of these generators when applied to the exploration of the properties and phenomena of electricity ...

Tesla Coil Geometry and Cylindrical Coil Design
Tesla used a range of different coil geometries throughout his experimental work, including flat[1], cylindrical[2], conical[3] , and separated cylindrical secondary with an extra coil[4]. Each of these different geometries present different advantages and different limitations, and hence it is important for any experiment using a Tesla coil or TMT system to choose a coil geometry best suited to the type of experiment at hand. Different experiments are designed to study different aspects of electrical phenomena and qualities including, displacement and transference of electric power, radiant energy and matter, wireless, single wire, and low-loss transmission, longitudinal modes and cavity effects, plasma and dielectric effects etc ...

Negative Resistance and the Self Generating Discharge
Negative resistance is a feature of the I-V characteristic of a discharge between two electrodes, and if correctly utilised can lead to unusual electrical phenomena within an electrical circuit. In this first part on this topic we explore the I-V properties of the negative resistance (NR) region of a carbon electrode spark gap (CSG), or carbon-arc gap. When the CSG is biased into the correct region, and combined with a switched (non-linear) impetus from the generator, the impedance of the circuit can be seen to reduce from the conventional short-circuit case, increasing the current in the circuit and intensifying the light emitted from an incandescent lamp load ...

Tesla’s Radiant Energy and Matter
Some of the most fascinating areas of research into the inner workings of electricity, are those that display unusual and interesting phenomena, and especially those not easily understood and explained by mainstream science and electromagnetism. The field surrounding Tesla's radiant energy and matter, the apparatus, experiments, and wealth of unusual electrical, and even non-electrical related phenomena, is a particular case to note. This first post in a sequence serves as a practical and experimental introduction to this area, along with consideration and discussion of the observed phenomena, and possible interpretations as to their origin and cause. It is through working to understand these types of phenomena, often generated in high tension, unipolar, and non-linear electrical systems such as the Tesla coil and TMT transmission system, that the inner workings of electricity can be revealed little by little. That is to say, the outer workings of electromagnetism that account for almost all of those measurable electrical properties that constitute the transference of energy, and hence electric power, between source, load, and the intervening transmission medium, can be peeled back to show a more fundamental, coherent, and guiding mechanism ...

Vector Network Analyser – DG8SAQ
This post on the Vector Network Analyser, the DG8SAQ by SDR-Kits[1-3], is the first in a sequence looking at how to use advanced test equipment to measure the properties, characteristics, and electrical parameters associated with Tesla coils and TMT transmission systems. The small signal ac input impedance characteristics Z11, and also the transmission gain characteristics S21, are used a lot in the experiments and measurements presented in this website, and yield a lot of fascinating and intricate dynamic data that can assist in the design, operation, matching and tuning of experimental apparatus suitable for experiments in the displacement and transference of electric power ...

Transference of Electric Power – Part 2
In this second part on the transference of electric power we take a look at the differences that arise when a spark gap generator (SGG) is used as the power source for the experiment rather than a single frequency oscillator as used in part 1. It is recommended to study part 1 before this second part, in order to gain an underlying understanding of the overall experiment, phenomena, results, and suggested interpretation of the experimental results, that are characteristic to the practical investigations in the transference of electric power ...

Transference of Electric Power – Part 1
In this first part we will look at both video experiments and measurements to investigate and demonstrate the transference of electric power via the transmission medium of a single wire, and combined with and without multiple loads. The experiments are undertaken using the flat coils designed, measured, and tested in detail here. Part 1 of this topic is intended to experimentally introduce the transference of electric power, and the various properties, phenomena, and effects that can be measured within such an electrical system when excited using the vacuum tube generator as a feedback oscillator, details here ...

ESTC 2019 – Tesla’s Colorado Springs Experiment
ESTC 2019, the Energy, Science, and Technology Conference[1], included a presentation and working demonstration by Eric Dollard on Tesla's Colorado Springs experiment[2] (TCS), which is available through A & P Electronic Media[3,4]. Due to unforseen circumstances relating to the demonstration co-worker, the generator for this experiment was unavailable after the demonstration for additional experimentation, investigation, and follow-up demonstrations. In agreement with Eric Dollard I suggested that the spark gap generator from the Vril Science Multiwave Oscillator Product[5], (MWO), could be adapted, tuned, and applied to the Colorado Springs experiment, and in order to facilitate ongoing investigation and experimentation throughout the conference period. What follows in this post is the story of how this successful endeavour unfolded in the form of videos, pictures, measurements, and of course the final results ... Read post
Spark Gap Generator Measurements – Part2
Part 1 of the spark gap generator covered the major components of the system, along with the design steps taken to build a diathermy replica unit (DR). In this part measurements are carried out both in the frequency and time domains, to further understand the operating characteristics, and how best to match the output of the generator to the experimental load. In this part there is also consideration as to how the generator transforms the incoming mains supply to an output suitable for experiments in the displacement and transference of electric power ...

Spark Gap Generator – Part1
In the early days of my research, and before we built the spark gap generator, it was unclear to me which parts of the electrical system were most directly responsible for generating unusual electrical phenomena, whether it be the generator or high voltage source, the types and arrangements of the various coils, or a combination of these elements setup and arranged in a specific manner, tuned in a specific way, and operated in a specific method ...

1920s H.G. Fischer Diathermy
Later in the research, (and after the replica diathermy unit had been designed and built), I was lucky enough to come across a real 1920s H.G. Fischer diathermy unit (HGF), which although being sold untested, and in unknown condition, looked suprisingly good from the pictures. It survived the shipping from the USA to the UK all in one piece, and on closer inspection proved to be in good physical and working condition, including the thermo-ammeter, and the original fuse. The only part missing was the 6V power indicator bulb ... Read post
Multiwave Oscillator Impedance – Part 2
In part 2 of the multiwave oscillator impedance (MWO) measurements we take a look at the high frequency impedance characteristics Z11 for the MWO resonator rings (top-load). The MWO Tesla style drive coil measured in part 1 needs to be separated from the MWO top-load for this type of measurement, because the impedance and load of the drive coil masks out any resonant features at higher frequencies, making it impossible to measure the MWO when connected to the top of the secondary coil and measured at the input to the primary coil ...

Multiwave Oscillator Impedance – Part 1
The original Lahkovsky Multiwave Oscillator (MWO) apparatus combines two Tesla style drive coils in a transmitter and receiver configuration, each consisting of a primary and secondary coil cylindrically mounted on axis. The top-load for both transmitter and receiver is a complex combination of concentric half-wave resonators. The impedance characteristics of even a single drive coil with top-load represents a complex measurement challenge with results that can span over a very wide frequency range, in the order of 100kc/s - > 1Gc/s ...

Vacuum Tube Generator (811A)
The vacuum tube generator (VTG) mainly used for experiments in the displacement and transference of electric power is based around a pair of 811A power triode vacuum tubes, of either RCA or Russian origin, and with electrical characteristics generally as defined in the RCA 811A datasheet. The 811A's have demonstrated to be highly flexible, with high reliability, and good overall medium power performance, versus cost and availability, when used in a variety of different configurations. The final output of this generator with these tubes can provide a maximum sustained RF output power of ~600W, and peak output for short bursts (up to 10s) of 900W, and over a wide frequency band up to ~5Mc/s ...

Displacement and Transference
As an experimental researcher it is normally always my preferred choice to share and discuss any theory I may hold about my work and the larger subject area according to the progression of the experimental work, and whether it corroborates or refutes any specific theory, principle, conjecture, or hypothesis I may hold. The principles that appear clear in my mind, regarding the displacement and transference of electric power, have guided the entire direction of my research efforts over a good many years to establish the validity or otherwise of these principles. In other words, I am designing and building the nature of my experiments in such a way as to attempt to reveal and test these working hypotheses and conjectures, and in so doing uncover and make further known the inner workings of the electrical wheel of nature ...

Flat Coil Impedance – Part 3
This part measures the coil impedance characteristics Z11 (magnitude and phase) for the flat coil in a range of different experimental scenarios. There are some preliminary results presented here in order to give an indication of the more complex frequency characteristics that exist within the experimental scenarios. The measurements and explanantion of the results presented here is still work in process and hence this post has not been fully finished at this time. As soon as time allows I will extend the range of measurements and experiments, and provide more detailed explanations and implications of the presented results ... Read post

The design, implementation, and measurement of a flat coil is presented in the following sequence of posts. This coil has then been used in a range of experiments including single wire effects, wireless transmission of power, and investigations into the properties of displacement and transference of electric power.
