Peter, whatever happened with Eric P. Dollard?

[t-rex]

Eric, thank you for all the very detailed transmissions bringing us ever closer to making the TMT replication a reality.
I have a few inquiries... You are describing the coils and theory of them better than I ever hoped for. I believe understanding the excitation of the primary is also imperative and the next logical step (not that I'm done learning about the coil arrangements, please do continue!) Did you excite the primary coil with an AM transmitter, and if so, what did you seek for an impedance output for the transmitter or rather the impedance input of the primary coil once the secondary and extra coil are optimized for the frequency of operation?

The primary is driven with an AM transmitter, or HAM radio transmitter, the primary coil and capacitor must be the tank circuit in a push/pull situation.(vacuum tubes not spark gaps. stay away from spark gaps). All of this stuff is in Condensed Intro to Tesla Transformers. I'm going back into the mountains now, so I won't be able to answer any questions. I'll come back into civilization if people can get something built, or if someone can get the money together to pick up the stuff in Morro Bay.

TMT Primary Coil Excitation & Conductor Inquiry

Eric, thank you for all the very detailed transmissions bringing us ever closer to making the TMT replication a reality.
I have a few inquiries... You are describing the coils and theory of them better than I ever hoped for. I believe understanding the excitation of the primary is also imperative and the next logical step (not that I'm done learning about the coil arrangements, please do continue!) Did you excite the primary coil with an AM transmitter, and if so, what did you seek for an impedance output for the transmitter or rather the impedance input of the primary coil once the secondary and extra coil are optimized for the frequency of operation? I doubt one would get that 50 ohm match that solid state and tube transmitters are engineered for maximum power transfer. (I'm well aware solid state cannot be used in this application & I know tubes can operate well outside of this 50 ohm match. I've heard that many years ago ham operators would tune the output of their vacuum tube exciters with a 100 watt light bulb on the output and tune for maximum brightness! I'm 32 years old and didn't get my ticket until 1999, so I got in the hobby when solid state was predominant, so I appologize for any misconceptions). I recall you mentioned that when transmitting into the ground with no antenna on 160 meters, one would seek an SWR of infinity, as well as high plate currents in the tubes. Does the same set of inverse circumstances exist with the TMT arrangement?

Another question I have since reading and understanding your transmissions: I now know that electricity flows on the outside of conductors (or reflectors) in the magnetic and dielectric fields. That being said, why is it that with high current DC (or 60cps AC for that matter) that the wire gauge must be large or the wire will heat up and eventually melt due to I^2*R, if the electricity travels outside the conductor? (I know at substations on 765kV, 345kV & 138kV buses, hollow aluminum tubes are used.) One would think that since only the surface area of the conductor is utilized in generating / sustaining the fields, why can't we use large hollow conductors even with high current DC, what good does the core of the wire do with high current DC? (I am well aware of "skin effect" and understand that the higher one goes in frequency, the thinner this layer is.)

Kind Regards and keep up the transmissions,

Eric, the use of Radians is brilliant. I do have a question, have you investigated the length of the radian in respect to a time variant helix?

The known: Frequency is a time variant, radians are time invariant. a cycle is time variant and thus the sine wave. the radians of 1 cycle without a time variant displacement have a fixed length, i.e. 1 rad= 57.29577 degrees. However in a helix the arc length is dependent upon:
X=a cos(t)
Y=a sin(t)
Z= ct
so that L=2Pi sqrt a^2 + c^2 where C= pitch/2Pi
then, rad = (L/a)^-1
Ok so what of it? wouldn't the radian thus have a time variant length based on the frequency? a radian of 1 would be a static time invariant length and would vary based on fq, the higher the fq the closer to 1.

Primary is floating?

It is center tapped. The primary is balanced. There is no connection between the primary and the secondary.

Eric,

I am having trouble understanding how you chose 14 gauge wire to be suitable for the secondary winding for 1000 Kc per second transmitter. When I used your formula given above for the (6) "Maximum Solid Conductor Diameter", It gives me 0.51 mm, the equivalent of 24 gauge. 14 gauge is 1.63 mm in diameter. It would seem that the 14 gauge as prescribed by you is larger than the maximum diameter according to your formula at 1000 Kc per second.

Dave

The 14 gauge is the best compromise size. That way no fancy coax, you still have enough surface area to keep the magnification factor high. Obviously 8 gauge would have to be hollow to be useful. Remember the frequency given is approximate. Someone is going to have to build one to see how far off it is. Examine closely the frequencies in the Extra Coil in the Tesla Colorado Springs Notes, very closely. In the Theory of Wireless Power use the design equations to find the characteristics of the coils I presented in these recent presentations of the Crystal Radio Initiative.

Interesting stuff...

It sorta sounds like the point is to have a driver circuit that when not shorted out it has a very high inductance and when shorted via the spark gap it would invert the very high inductance on the order of a few hundred Henries to a capacity of over 1000uF (the capacity increases based on the conductance of the arc in the spark gap, just shorting the gaps electrodes together gives one a reading of about 60uF-1000uF with the higher reading being a result of putting pressure on the electrodes to force them into better contact.)

That said I use a darsonval style driver that has a pair of teflon doorknob caps at 3300pF each, one on either end of the primary which consists of 5 turns of 1/4 inch soft copper pipe bent into a 6inch diameter helix. The spark gap is on the opposite side of the capacitors from the inductance. The spark gap side is fed HVDC by an oil ignition transformer and the gap is set to arc from 2000vdc to 5000vdc via manual adjustment of the gap while the system is running.

I don't mean to come on this thread and hijack the thought process, but I wanted to share a way that might get us to where Erics gone more quickly. I also need to take the time to see about the weight comparison between primary and secondary as that might be pretty close on my setup, tho I'm outside the height to length dimensions noted by Eric.

I use an open odd layout in my collection side of the circuit that uses 2 coils on the common axis of alignment, Both coils are shorted out to themselves and a single wire is run out from both coils to a pair of diodes setup similarly to an avramenko plug on the end of each wire. And yet this output delivers charges that are 10-12,000volts in potential which I'm in process of sorting out how to step down to usable levels. I'm willing to share specifics and would actually like it if Eric might review what I've done as I've not see anything else that looks like my arrangement before. I can be reached at bellerian1@comcast.net if Eric would be so inclined to contact me there, I'll share with him the schematic and details to see what his insight might add to my own understanding of the same. (you can also go on youtube and search for bellerian apparatus or bellerian device and see what this thing looks like and how it seems to be working.) Its just hard finding someone with actual bench experience to discuss it with as most like the math aspect and the theory more than the doing. So thought I'd post here and see what might come of it. Sorry for the distraction, please continue.

Regards,
Gene

Helping Eric

Dear Eric and all,

I am not sure whether this helps Eric, but he can stay in Victoria BC near Seattle where I am. And I know an electrical bike shop owner with an office space, I have some options to work and gain money for further costs.

Eric please let me know if this helps. Otherwise, please do not give up hope until I can rake up some money. Meanwhile, if all of us in this forum donate some money like 20,30,50, 100, 200,..... I think the money he wants gets manifested.

Please continue fundraising and help this man. It is as important as research guys! I am off to paypal now.

Weight of silver plated copper shield.

1, My understanding is that the inner conductor is never used, or connected. Free floats within the Teflon, although it acts as a "reflector".
2, Don't know, probably not.

I have actually measured weight of the copper shield within RG-178 Co-axial cable. (Not just calculated but striped 1 meter and measured on an accurate analytical balance).

Actual weight of Cu shield in RG-178 Co-axial cable is 3.54 grams per meter. (3.5384g)

I will post Cu shield weights of other co-axial cable when available (RG-316 next).

Thank you for the weight figure, this will take the guess work out calculating veights.
I still need an answer to my second question.
As far as the frequencies concerned, Eric picked 1,000Kcps, but if I do not have any radio station transmitting on that frequency near me then I suppose I can use other frequencies. How about short wave stations in the Mcps range. The important thing is the amount of power they are transmitting with and the distance to the "Tesla receiver". Do we have an equition for the power drop-off as function of distance from the transmitter? Is it simply 1/distance or 1/distance squared or some log function?
Last week in my post I mentioned that, we should look at the available equipment at Morro Bay. If it is only a few thousand dollar and if Eric determines that they would be useful to him, then we should make an effort to get them and store them until a lab-site is found. Somehow I have the feeling that many people on this forum (probably mostly guests) do not truly understand Eric Dollard's significance. It is like a fleeting moment, that comes and goes in a blink of an eye. Those of us who realize what are we part of thanks to Eric, should make all efforts to find a solution for Eric's situation. May be Eric's main contact should run a survey to see how much pledge is there to support this effort.

Weight of Cu Shield: RG-178

Thank you Eric very much for your valuable help in figuring out what is right and what is false. Two coax cables which have similar sizes to the one used in your 1980's Longitudinal Wave video are the RG178 ang the RG316. One of the manufacturer, Wellshow, gives the following specifications.
RG178 - .071" insulation OD, .041" shield OD, and center conductor is silver coated copper covered steel wire, 30AWG.
RG316 - .10" insulation OD, .067 shield OD, and center conductor is silver coated copper covered steel wire, 26AWG.
The questions are:
1. Do we connect the center conductor to the shield?
2. Either way, connected or not, does the center steel wire conductor acceptable for operational purposes, i.e. possibly creating a magnetic field that could interfer with the desired coil resonance?

1, My understanding is that the inner conductor is never used, or connected. Free floats within the Teflon, although it acts as a "reflector".

Coyote like idea

When I spoke to Eric, he told me to let everybody know that he has finally grown sick of interacting with society. His driveshaft is still missing after many email attempts of getting a hold of the individual that supposedly has it. On top of that, the car parts that were promised to him have still not manifested. It seems like it is just easier for some people not to help Mr. Dollard rather than sacrifice a little time and effort...

He told me that he will be cutting ties with society as much as possible. He may write another book just for the sake of boredom as he doesn't see a laboratory becoming a reality at this rate. If there is anybody out there that can possibly do some fundraising for Eric or get in touch with him about investing in furthering his research, there is a load of equipment at a scrapyard in Morro Bay that has most everything that he would need to build a lab. Estimated cost is a couple of thousand U.S. Dollars. It would be a shame to see Mr. Dollard share the same fate as Dr. Nikola Tesla, broke and homeless (lab-less).

Eric, I just wanted to say thank you for everything that you have presented. I can guarantee that your efforts will bear fruit. It will just take longer than expected since none of us are properly funded for R&D. Don't lose hope yet.

Dave

It would be my hope that there could be a possibility of setting up some sort of Lab for Eric, perhaps not the multi-million dollar lab that he deserves, but perhaps a shoe-string budget Laboratory at some location, where Eric can access equipment, tools, and building materials. Unfortunately though, it seems everyone is broke, myself included. I send a little money now and then but it isn’t enough to set up a Lab. However might there yet be hope, it still exists..

Eric has given the design instructions and formulas (which are absolute gold in my opinion) and there is now enough information to begin immediate construction. One might say, concerning the Crystal Radio Receiver Initiative, that it’s a heck of a lot of work and money to spend, building a Tesla type crystal radio receiver, just to light up a small light bulb. However it’s actually a rather brilliant and Coyote like idea, for several reasons.

1st - As Eric says it will prove Tesla once and for all.

2nd - It teaches us how to properly construct a Tesla coil type radio system, a valuable teaching unto itself.

3rd - Teaches us how to receive a signal, one must know how to receive before one can begin to transmit.

4th - No license is required to receive an AM radio signal.

5th - It would be great fun to just (briefly) “pull the rug” out from under the local radio station.

6th – Other reasons not yet realized.

Obviously, each builder would select their own local radio station to tune into and build their system up for that. Learn how etc. Eventually however, given time, some money and a little experience, those whom are ready, once the systems are in place, (I.e. good grounding systems etc). I would suggest that particular frequencies be chosen and agreed upon world wide, thus to begin the possibility of transmission and reception of a Tesla Type, Non-Electromagnetic, World Wide Radio System. E.g. From the USA to Australia, or other locations around the world, where these Tesla Radio Systems are constructed, the possibility to send & receive transmissions, through the Earth at Pi over two times the velocity of light.. Something that is actually achievable & within the realms of possibility.

Electric farmer Dollard, has planted the seeds, they will soon spout and grow, and they are not easily up-rooted.
