    Eric Dollard Forum:


    I go to this Forum today and see that I have some 20 odd private questions from individuals about various segments of my research dating back to 2013 that I have posted here but how come I am only seeing those now and not when they were first posted?

    My humble apologies to those people as I was not aware of those messages until today.

    I am open to objective criticism but if somebody asks me an intelligent question, I do my best to give a truthful answer supported by the research and to do otherwise is not me.
    Those questions would have been better to be presented at the main Forum and not privately and would appreciate those who are still interested to repeat their question - Thanks.

    Some of the questions were to do with rainmaking but you must all remember that this is exactly what Tesla first endeavored to design but his early results led to a much greater discovery in the 'radiant energy' and its enhanced properties.

    I am also active at Groups io and MeWe and may be more suitable and comfortable there for you and you are most welcome to come and join this specialized arena:

    We used to receive notifications when somebody posted here but that is no longer happening and why nobody responds.

    That's some pretty nice stuff you got going in those pictures. Keep experimenting, we need more people in the world who are experimenters, and less people that talk but don't act.

    I've never read Ernst's books, so can't give you an answer on his technical details that were used. I know from reading and watching Eric Dollard's work, the "Earth" resonance is around 18 kilohertz, or 18 kilocycles per second, though maybe you know that already.

    From what I've read of many of Tesla's lectures, patents, articles, etc... I've never heard directly he wanted to use his transformers to control the weather. There was one reference to it directly in a to-be patent, but was never filed. His transformers were designed for the primary function, transmission of electrical power through the Earth. A lot of the "burning nitrogen" and weather related stuff that's Carried by Ernst and Bill Lyne, seems to be overexaggerated and misinterpreted in my opinion. Thinking there's some "secret" encoded in Tesla's writings seems really silly to me. I don't think Tesla was making significant efforts for weather control, they were probably just ideas being proposed like what happened after he exiled himself in the New Yorker Hotel, and gave teases to news reporters about what he claimed to have invented and found.

      Hi,
      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. It is also demonstrated that more than 500W of power can be transferred through a single wire no thicker than a human hair, a 40AWG (0.08mm or 80 microns).

      The video experiment demonstrates and includes the following:

      1. Linear amplifier generator setup, matching, tuning, and operation to drive a cylindrical TC and TMT system.

      2. Measurement and confirmation of the series and parallel modes of resonance for a balanced TC, against the Z11 impedance results, using the generator exciter and an oscilloscope.

      3. Transference of electric power from the generator exciter unit, to a single wire transmission medium incandescent lamp load up to 120W.

      4. Transference of electric power from the linear amplifier generator to a 500W incandescent lamp load at the TMT receiver output, and subsequently to two parallel 500W lamp loads.

      5. Longitudinal magneto-dielectric (LMD) mode measurement through central null with a fluorescent lamp, and mode interference patterns with an ultraviolet lamp.

      6. Transference of electric power efficiency measurements up to 99% using an AWG12 single wire between the TX and RX coils.

      7. Efficiency measurements up to 100% using an AWG40, 80 micron (0.08mm), 60cm long, single wire between the TX and RX coils.

      Best wishes,
      Adrian
      Dear Adrian,
      You are doing fascinating work as always.

      Considerable discussion has taken place on the need for an extremely low inductance and low-resistance ground system in the design of TMT power transmission systems, but here you demonstrate power transmission over a high inductance, high-resistance medium.

      Do you have any explanation for the apparent ease in which you delivered power via an 0.08mm wire, while Tesla and others needed tonnes of copper to achieve a suitably low impedance connection to the earth?

        What really bugs me here is the fact that the USA during WWI set up an underground antenna for Continental USA to Europe communications that was dismantled entirely after the war and never used again.
        The antenna was the Rogers underground and undersea and the only frequency reference I could find was that for 1150 meters which is about 250 khz with C = 0.035 uF and L = 1 mH.
        A possible forerunner for submarine V & ELF communications which began at about the 200 khz area but today is much lower and down to <20 khz.

        http://www.rexresearch.com/rogers/1rogers.htm

        What I see here is something that could be used at HF but I don't see anybody doing such leg work to see if this is at all possible.
        Eric talking of a 10 acre aerial farm and a probable impossibility but why don't we begin to use the underground aerial theory and at HF would be just that much simpler, don't you think?

        I made a Post earlier on this and was developing a system similar to Roger's Fig 7/8 but have not as yet done so.
        This was no more than a hole in the ground big enough to contain the large pvc pipe/s that contained the antenna with granite surrounding the pipe - an added coherer if you like.
        I was looking at a 150mm 6" pvc with end caps but I'm sure you can get bigger with the length being the main criteria.
        More than one for effect - build two and you have your stereo requirement.
        I am into aerials at this time as I am building a directional rectangular parabola for the Juan Biagorri Velar rainmaker and have the final design and parts for 60 mhz 5 meter but still waiting my attention.
        This is another Vacuum Tube initiative and looking at 6SN7GTAs or even 807s.
        What I do have here is a Yaesu FT-901D (6146Bs) and may simply use that as the transmitter matched into the antenna with a variety of modulation means available.
        There is a research band at about 54 mhz which I will try to encompass in all of this by not breaking any laws regarding illegal transmissions.
        Fun stuff!

        The Spectrum Analyser has arrived and looks good but untested - GQ EMF-360V2 - 10 Ghz - Seattle address.
        We need to understand what we are seeing on the meter and attempt to recognise it as a dbm or watts reference or a something else.

        Food for thought.

        • I see many comments and effects. Is there a person capable of giving an over all statement that explains goals? In other words, what is it for, what is it suppose to do? Or should it be doing? What is it?

          Yes it throws sparks, radiation and radio waves and has a transmitter and one receiver which is around a 50% conversion efficiency. So what does this show? or is it a learning tool possibly? what is the purpose? beautifully done hardware construct.

          Underwater radio?

            The EHT supply pcb is being driven from what source - 110vAC 60 hz?
            The reason I question this is because what is being used in ceramics will not give you the voltage you expect.
            Thank you for your continued support .

            The linear amplifier takes its power source from the standard UK line supply which is AC 240V 50Hz. The HV transformer inside the amplifier steps this up to 1200V, and further with a doubler to about 2400V anode potential. With judicious tuning of the PI-network in the amplifier and the T-network antenna tuner, (not to the system impedance of 50ohms), quite a bit of this potential can be exposed to the experimental apparatus.

            A question for you, from my investigations amd experiments so far, (still ongoing), it appears that the self-generating discharge utilises the abnormal glow region of the spark gap I-V characteristics, which represents a negative resistance in the spark gap region, and as demonstrated and measured here:

            http://www.am-innovations.com/negati...scharge-part-1

            Given that this specialised bias region appears to occur only at low currents e.g. around 100mA, and requires very delicate and precise bias adjustment, how would you practically propose to make use of this fascinating principle and phenomenon in a high-power disruptive discharge powered TMT system ?

            • Dollard Forum Adrian Part1:

              Hello Adrian,
              Good with the power supply!
              Good question but I haven't answered yours yet and see Part 2.

              When we discovered the plasma phenomena in the Impulse Discharge, I then set about attempting a down conversion from the storage capacitors (4kv) into a 240 volt power supply.
              First efforts were with Gas Discharge Tubes but all this did was burn them out - this is what Don Smith had used but was hopeless.
              A spark gap showed me that I could keep a 240v 100watt lamp glowing reasonably nicely but was most unreliable and that is when it looked capable of OU - about 2.5 watts in (12v @ 200mA) and 100 watts out - all analogue metering.
              Carbon tips being used here from D batteries and in there is another OU prospect in why it was that they stopped using carbon for anodes in large Tubes 805/813 etc and I still do not have an answer - Eric - anybody?
              The DVM is measuring voltage at the caps via a 1000:1 homebuilt probe and shows 1,182 volts:

              nsmail-181-1.jpg

              This device was then put on the backburner in an attempt to discover a reliable means for the down conversion.
              Along came Eric Dollard and gave me some beaut Thyratron schematics like in the TMT Pulser (2050) and the Cosmic Ray Detector (OA4G) and pretty much there was my answer but still not finalised at the bench.

              Direction here is to disable the current pulser power supply HT and use the 600 volts from the storage capacitors to drive the system at 50 hertz into an output transformer for the 240 volts ac.
              There is a circuit in the RCA Manuals that shows a power supply using thyratrons (2050) and this kind of sealed the problem.
              This is from RCA Ham Tips Nov-Dec 1946:

              nsmail-180-1.jpg

              Also have plans to use the Tripler with the Flyback for 27kv and have actually done this but my records are incomplete and I have no idea why and requires a review.
              Lots of work still to be done here to simplify the circuit to make it reliable but the thyratron is an answer.
              There may be other alternatives and I am open to suggestions.
              The high voltage driver Mosfet that goes with any flyback is also a possibility and I already have that set up as an option.
              I have been collecting HT transformers here for quite some time and I feel it is just a matter of selecting one that can be reversed to give the 240 volts output.
              Some of these transformers are huge, one I can barely lift but all worthy of testing.
              Have also been collecting Thyratrons where the anode power requirements are in the Kvs as an option to Eric's 2050s which are limited to 450 volts ac.
              Working with something generating another plasma also seemed like a good idea.
              The ether loves a vacuum!

              I had to stop what I was doing in the Lab as I ran out of safety space and am still in a reorganising mode.
              I am really tempted to buy two shipping containers where I can put a roof up between them and continue testing in that environment.

              Trusting that answers your question - it doesn't as I have just reread yours and will now answer that in a second post.
              All the Best.

              • Dollard Forum Adrian Part 2:

                To answer now with respect a TMT system.
                I had not thought of using the plasma phenomena in a TMT system but simply - why not?
                Refinement of the Impulse Discharge (ID) device was a paramount direction before entering into any other use.

                Yes, the initial tuning is a delicate procedure and my probable answer was to not power the TMT in this manner but to use the conventional approach but where the two plasma balls were sited was the focus for refinement and where we needed to tune accordingly for a desired output.

                i.e., use the Dollard Pulser as the input where the input modulation frequency can be adjusted to the 95khz required out of the secondary and final output from the Extra Coil at 149khz and this being impressed across the plasma balls where the rope is used for fine tuning.
                Probably a lamp grounded locally somewhere conveniently away from the apparatus where an analogue meter is used to determine current across the balls and this to aid the tuning distance.

                OK, now having written the above, why don't we use the ID to power the TMT?
                This would give a true Tesla style input into the system and is most worthy of a try and will do so.

                My TMT as it now stands has a pair of high impedance headphones attached and I am listening to the local radio station from a distance of some 20" from the Extra Coil using a crystal set detector (1N34s) attached to a 3" silver capacitor plate from a transmitter.
                All passive and works well and the signal IS coming from the Extra Coil.
                My Extra Coil is different to Eric's where we have had a disagreement on winding procedure and length etc - mine simply worked.

                Probable next step for me here is to use his Regenerative Magnifying Receiver (RMR)(2C22) and see if I can't pick up the signal on that.
                OK, good question which has led to further possible developments that might refine the overall system.
                Thanks for that and biting at the bit to get back into the Lab.

                To retune my system back to Earth Resonance I have calculated that I require a 1.5uF capacitor (plus variable) with a fixed L of 0.005mH at the primary.
                I presented something earlier but that was wrong as it was for the secondary and not primary.
                There is also some contention here with the frequencies used by Tesla and I feel he was doing a pi/2 at each of the first three steps and this fact has always bothered me.
                He was tuning for the LMD component at each stage and not TEM.
                Primary at about 58khz, secondary at 95 khz and Extra at Earth Resonace at 149khz and this is up for testing when I can get back to the TMT.
                Hope this helps.

                All the Best.

                • Hi Smokey,

                  Thank you for all the extra details.

                  Refinement of the Impulse Discharge (ID) device was a paramount direction before entering into any other use.
                  Ahead of writing-up a Part 2 on my website on the theme, Negative Resistance and the Self-Generating Discharge, I decided to do a "lash-up" experiment with both the Frolov and Don Smith variant of this Self-Generating Discharge circuit. Lash-ups are not my preferred way of conducting experiments, but nonetheless useful to understand the scope of the experiment ahead of a more formal part 2 video experiment and analysis.

                  Here are some links to pictures of my experiment, the Don Smith variant using a flyback transformer at 75kc, 10 x 100pF 3kV caps in series, a carbon arc gap set at 8mm, a 40kV bridge rectifier, and a 4uF 4kV oil-filled output capacitor. HT on the output capacitor is measured using a high voltage differential probe 1000:1 to the red voltmeter, and input current from the power supply on the yellow ammeter:

                  http://www.am-innovations.com/wp-con...2311/expt1.jpg

                  http://www.am-innovations.com/wp-con...2311/expt2.jpg

                  http://www.am-innovations.com/wp-con...2311/expt3.jpg

                  http://www.am-innovations.com/wp-con...2311/expt4.jpg

                  As can be seen in the pictures the output capacitor charges up to over 1000V (1.0024V on the meter), at a total input current from the power supply of 227mA @ 13.8V. The oscilloscope shows the flyback driver waveform, and the frequency meter in the top corner recording 75.4kc. The carbon gap is set at 8mm and finely adjusted, and with no discharge, no sound, and no light in the gap region.

                  Total power supplied into the experiment by the DC power supply is 13.8 x 0.227 = 3.13 W or 3.13 Joules per second of energy. The energy stored on the output capacitor is 1/2CV2 = 1/2 x 4x10-6 x 10022 = 2 Joules. At the steady state into a load we could say that the output capacitor can supply up to 2 Joules per second of energy to a load, equivalent to constantly illuminating a 2W light bulb. This makes the circuit in the region of 64% energy efficient from input to output.

                  I have also tried a range of variants in the circuit including:

                  a. The Frolov circuit configuration which appears to be less efficient, probably from only using a single diode rather than the bridge.

                  b. Using a 10kV 1000pF vacuum variable capacitor in place of the 10 x 100pF at the output of the flyback transformer. Adjustment here appears to effect the discharge quality a lot, but not the pre-discharge steady state charging of the output capacitor.

                  c. Adjusting the flyback driver frequency between 34 – 75 kc. Increased frequency improves slightly the energy efficiency of the circuit.

                  d. Fine adjustments to the carbon arc gap size, and the power supply input voltage.

                  e. Larger and smaller output capacitors, up to 60uF and down to 1uF. The capacity affected the time constant of the charging, but not the final steady state voltage on the output.

                  So far I find no evidence of over-unity characteristics, or any additional energy entering the circuit that is not supplied by the power supply. This circuit would also not be suitable to drive a TC or TMT system that needs strong oscillatory currents in the primary circuit. However, I do find two interesting phenomena taking place in the circuit:

                  1. Biased in the dark and abnormal glow region of the carbon spark gap IV characteristics, contributes about 20% to the charging of the capacitor, and some negative-resistance effects may be involved here. I checked this by removing the base connection between the flyback and the bridge rectifier. The capacitor was still able to charge up to almost 200V.

                  2. Single wire currents (LMD mode) from the base electrode of the flyback transformer contributes to about 80% of the charging of the output capacitor. I checked this by removing the spark gap completely from the experiment and leaving the upper end of the bridge rectifier unconnected. The capacitor was able to charge up to almost 800V.

                  These are my preliminary findings from the lash-up experiment, and I will go into much more detail on this, plus a video experiment, and the data in the analysis when I do a formal part 2 on my website.

                  Best wishes,
                  Adrian

                  • Hi Marcus,

                    This is indeed a very good question!

                    I start my reply from the summary that I made in the analysis of the experiment on my website at High-Efficiency Transference of Electric Power :

                    In summary, it is conjectured here that very high-efficiency transference of electric power is directly possible because of the LMD mode established in a single wire cavity, where the dielectric and magnetic fields of induction are guided around the low impedance single-wire conductor. The single-wire acts in this case like it were a monopole waveguide which would only be possible where the LM and LD modes are spatially in phase, but temporally out of phase, the condition that I conjecture is necessary for the LMD mode to form in the cavity. Real power can be transferred and dissipated at the receiver load via the single-wire transmission medium, because both the dielectric and magnetic fields of induction are guided across the cavity, and where both of these induction fields are necessary to transfer power over the cavity distance. It does not appear possible that transference of electric power can occur here through dielectric field induction alone between the transmitter and receiver coil, but rather that both the magnetic and dielectric induction fields extend across the system by virtue of LMD wavefront in the cavity, and indeed if the single-wire is disconnected from either end (guiding cavity terminated), then no power can be transferred from source to load.
                    I think it is important to establish here that the micro-strand (AWG40) single wire is already IN the cavity, in other words there is a very good connection to the single wire transmission medium at the bottom-end of both the transmitter and receiver secondary coils. My current understanding is that Tesla used tonnes of copper at the bottom-end of his TMT coils in order to "get a good grip of the earth", or to get the lowest impedance connection that he could between the transmitter and receiver and the Teluric transmission medium/cavity. To not establish this low impedance connection to the earth would be equivalent to me putting two higher impedance elements at each end of the transmission medium, which would restrict the output of the LMD generator (pumped secondary coil) to the single wire part of the transmission medium cavity.

                    The other thing I think that is important here is that we do not yet understand properly the impedance presented by a single wire to the LMD mode. We are assuming that this would be equivalent to the impedance presented to the TEM mode e.g. a narrow high impedance line at around the skin depth. This area needs considerably more work, but I would conjecture that maybe the 0.08mm wire does not look like a high impedance to the LMD mode, but rather since both the LM and LD modes are contained or guided around the wire like a monopolar waveguide they actually "see" a very low impedance path which is coherent over its length. This is only a suggested conjecture and would need to be explored in a lot of detail.

                    So in summary, I feel that the tonnes of copper is necessary to connect a high-power TMT transmitter and receiver to a Teluric transmission medium in order to properly establish the LMD mode across the entire cavity, (transmitter secondary + Teluric transmission medium + receiver secondary), and then the highest efficiency of transference of power from the generator occurs when the impedance across the transmission medium part of the cavity is optimum (or minimum) for the LMD mode, whatever that might constitute.

                    These are my thoughts so far on your question.

                    I will shortly be releasing a new experimental page on the High-Efficiency Transference of Electric Power where the single wire is now extended to 11m, which places the transmitter and receiver in separate rooms at the lab, and shows very interesting changes in the configuration and drive from the generator to establish transfer efficiency > 90%.

                    Best wishes,
                    Adrian

                        I agree with this! … even without all the power that we do pump into the earth, there is in my perspective more than enough as yet untapped energy within the earth and life. However, it appears so far that only a very rare few have been able to call-forth and attach their instruments to liberate even a little of this energy, and even less to understand the underlying principles and mechanisms that make this possible.

                        Throughout space there is energy. Is this energy static or kinetic! If static our hopes are in vain; if kinetic — and this we know it is, for certain — then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.

                        This for me is one of the greatest statements that Tesla ever made, and something that as yet is still waiting to be unlocked, how to attach our machinery to the wheelwork of nature, and hence call-forth that vast reservoir of available energy in a regenerative and sustainable cycle.

                        The purpose of my research is to attempt to find how to accomplish this!

                        • Hi,

                          I have added a new post to my website on:

                          High-Efficiency Transference of Electric Power - 11m Single Wire

                          http://www.am-innovations.com/high-e...1m-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%.

                          In the mid-field region with an 11m single-wire we will see that the balanced mode setup only leads to a maximum efficiency of ~40%. It is demonstrated that it is necessary to significantly mismatch the balance between the transmitter and receiver coils in order to get the LMD mode to extend across the single-wire transmission medium and restore transfer efficiency to over 90%. Transmitter and receiver primary circuit mismatch is mainly used to restore the transfer efficiency, along with fine adjustment through generator to TMT system TEM mismatch, measured at a range of Standing Wave Ratio (SWR) of 1, π/2, φ (the golden ratio), and 2.

                          The video experiment demonstrates and includes aspects of the following:

                          1. Small signal ac input impedance Z11 for a cylindrical coil TMT system in the mid-field region, and connected via an 11m 12AWG single wire transmission medium.

                          2. Z11 balanced parallel mode impedance measurements, for a reciprocal TMT configuration with 3 primary turns and matched primary capacitor tuning.

                          3. Z11 unbalanced parallel mode impedance measurements, for a non-reciprocal TMT configuration with 4 transmitter primary turns, 2 receiver primary turns, and mismatched capacitor tuning.

                          4. Transference of electric power from the linear amplifier generator to a 500W incandescent lamp load at the TMT receiver output via the reciprocal TMT configuration, and with a measured efficiency around 40%.

                          5. Transference of electric power to a 500W incandescent lamp load at the TMT receiver output via the non-reciprocal TMT configuration, and with a measured efficiency of up to 96%.

                          6. Demonstration of the high tension and associated discharge that can be drawn from the high-end of the receiver secondary coil, via the 11m single wire.

                          7. Transference of electric power efficiency measurements up to 96% (90% average) at 400W dissipated load power (peak 500W), in the 160m amateur radio band at 2.01Mc, and via an AWG12 single wire 11m long between the TX and RX coils.

                          Best wishes,
                          Adrian

                          • Hey Adrian,

                            I really like that your doing some solid experimentation on this subject, think it's important to either validate or invalidate the myths associated with the TMT. You've also got some really good gear lol.

                            Haven't had a chance to glance over all the work you've done on this system but had a couple of quick questions:

                            From a Maxwellian stand point the single wire transmission that you have could be considered like a waveguide with a thin dielectric around it. In this case your transformers on either sides might be considered the launchers of a surface wave along the single wire path. The wire would support a transverse magnetic mode (TM) along the waveguide. I'm not saying that's what it is for sure but if you think you have a null point half way between the transmitter and receiver (I think you said something about that on the transference page please correct me if I'm wrong) then that suggests that it isn't a Zenneck wave because standing waves do not appear in the Zenneck wave regime. What's the length of the wire in each secondary coil relative to the wavelength?

                            In the normal surface wave regime you can get standing waves but I have never seen a transference of above 90% in a surface wave system before, as a lot of the energy is carried off as an evanescent wave or is radiated away by a non perfect TEM to TM conversion into the structure (from the coax which I have worked with, I haven't used coils to transmit like that before) that's having the power sent through. It looks like your system (depending on the secondary's wire length is) might be smaller than the carrier frequency but just wanted to ask before asking any more questions. Depending on the length you would either get a real current movement as opposed to a displacement current I tentatively think.

                            Have you been able to measure or simulate the electric or magnetic fields around the single wire? If they were 90 degrees out of phase with the electric field perpendicular to the wire surface then that would definitely be a near field surface wave. If not then it may well be another transmission mode, which would be really interesting.

                            Another thing that might help to see what mode your using might be to look at the speed that the wave propagates down the line, but that might only be possible in simulation with such a small length. Because there is a dielectric around the single wire conductor it would reduce the speed that the wave travels down the line to lower than c, and it would also confine the electric field closer to the wire. If there really is an LMD mode then would expect it to travel faster down the line than that mode.

                            I'm also based in the UK and did my PhD in surface waves on metal structures but haven't had much exposure to this type of system with coils as transmitters/receivers apart from in Zenneck wave power transmission and inductive coupling.
