Hello Diaodon,
Excellent post.
Longitudinal waves exists, they have never been observed to move faster than the speed of light though. (which is my point)
Longitudinal waves exist as pressure waves from explosions. Or the initial release of energy in earthquakes. Or in plasma (which I just learned thanks to you :)  )
But these exotic LMD waves are yet to be observed, I just think if they are real and people understand them why can we not observe them. I also understand they were put forth by Dollard. A man who reads books under the light of bulbs powered by nuclear power yet still supposes that nuclear physics is false.
The video with the examples of waveguides (antennas) was cool until he bashed Einstein and relativity claiming it be never proven experimentally, also his video was a demonstration of how antennas work, it has nothing to do with longitudinal waves (at least from what I saw)... I find it hard how Dollard followers overlook nuclear weapons, nuclear power, the adjustment in the clocks of GPS satellites due to the discrepancy in time due to their respective velocities via special relativity, not to mention gravitation lens effect observed in astronomy.

Excellent post in explaining longitudinal waves, but it does not bring us one iota closer to evidence of the exotic LMD waves put forth by Dollard.

Thanks for the clear concise post.

Peace,
Ben

Ben, can you adequately explain how the Tesla hairpin or stout bars circuit behaves as it does?  How is it you can connect a lamp across a direct short and have it illuminate as has been demonstrated multiple times?  What form would the energy there have to be in to allow this manifestation to occur?

Dollard could be wrong about some things, but even so is it wise to throw out everything he says?  He's probably the only still living connection between us as Tesla.  BTW, he worked at RCA Bolinas, CA.  A lot of money was spent there doing something of value.  We have no idea what Eric may have seen there or the people he was in touch with.  There's no possible way you could have walked in his shoes, give the guy a little credit.  Or, throw the baby out with the bathwater and start over.  Don't be surprised if you hit a dead end.

Matt, there is always an underlying condition which allows us to gain access to the strangest phenomenon in nature. In order to experience particle wave duality or superposition for example, for it to act as a wave function we must first remove the observer or add the observer in the case of particle function, in the case of Stan's circuitry we must first remove the current to be able to observe electrostatic behaviour which Dollard says is actually dc. In the case of the light bulb operating in a dead short situation: The drive circuit doesn't always see a dead short, it depends on the impedance at the end of the line, for example on loop antennae which is a dead short as far as current is concerned, because of the high impedance node half way around the antenna, the drive circuit actually see's the antenna as open circuit and you could place a light bulb across the node and illuminate it providing you match the impedance. So here we have an antenna that is a short circuit which operates as a open circuit at high impedance values. Where there is high impedance there is no current in certain locations on transmission lines and differential lines.

I will say this becuase its a healthy exercuse in acceoting oeople for who they are. Just becuase Babe Ruth doesnt believe football should be called a sport, does not mean you shouldnt listen to what he has yo say about baseball.

Hello Matt,

In the Tesla Hairpin Circuit you have AC impulses (it will work the same with DC impulses)  going into a one turn inductor (or you could call it a half turn), when the impulses hit the half turn inductor a electromagnetic wave where the wave length corresponds to the wavelength off the 1/2 turn inductor will propagate. Since there is a sine wave resonating across what is essentially a transmitting antenna, you will have different potentials at different points on the 1/2 turn inductor... When you put a bulb across the 1/2 turn inductor, you have 2 conductors touching different potentials of an electromagnetic sine wave  hence lighting the bulb.... I cannot come up with an experiment to prove the existence of LMDs but I would bet if you touch the bulb 1/4 of the length of the half turn inductor you will get max illumination. I think I will build a replica of the THC to show this point... Remember, the wavelength will correspond to the length of the 1/2 turn inductor. So if your 1/2 turn inductor is 8 feet long the resonant frequency will be 120.88MegaHz, (i'm just bringing this up to remind us that we are dealing with high frequency AC with the THC).
If I were to do a replica I would have to have a loop that is quite long for my 50MegaHz scope to observe it.

Now, back to Dollard, yes he did work for RCA (very cool, a serious accomplishment), but he also is an admitted methamphetamine user, and I am sorry, I cannot overlook the fact that the man denies experimental proof for nuclear physics and relativity when they are so clearly evident in modern society.. Tesla gets a pass for his judgment of nuclear physics and relativity because he died before the empirical evidence was shown and created public. But guys like Dollard who are alive today and deny Einstein, nuclear physics, and relativity. <-- they are being ignorant, literally. Because they are ignoring tonnes of empirical evidence that is clear and right in front of them. I think ignorant is the 100% most accurate way to phrase it.

I did like Dollards "History Of Electricity" , it was a well thought out presentation, which I've watched many times. But the man is crazy to deny nuclear physics, Einstein, relativity... And he was the one who put fourth these LMD waves, and we are all yet to observe them. Maybe he was hopped up on some meth when he thought of the LMD waves. I don't know. But anyone who is blatantly ignorant to empirical evidence goes way WAY down on the credibility scale (IMHO). ... Methamphetamine abuse does horrible things to the brain, I'm sure Dollard was truly brilliant when he worked for RCA. I think he is an interesting character that is very knowledgeable on the history of electricity and electrical physics. But his LMD wave theories are wrong (IMHO), just like his assertion that nuclear physics, and relativity have never been proven (which is factually wrong). I like his presentations, but his exotic LMD wave theory is yet to be proven experimentally/empirically. <-- and likely never will be.

Comparing Tesla to Dollard is a huge disrespect to Tesla. Tesla was a truly great man, Dollard is a troubles soul with few accomplishments. (<---few accomplishments compared to Tesla)

I wish I had a faster oscilloscope so I could build a smaller Tesla Hairpin Circuit to experimentally show you what I am talking about.

I know you want these LMD waves to be a real thing Matt, and so do I. If they are real, then we should be able to build an apparatus and experiment to test for them. I'm all ears for ideas to build some sort of test to prove or disprove the existence of LMD waves.

I think I'll build a THC just for fun one of these days (or years) I have a nice 9kV 30mA NST (thanks Diadon ;) 
It won't be for a good while though, have to stay on the LENR path.
Taking time to explain the THC is not what I'm here for, I'll do it for fun one of these days or years. But its not a path that I see producing any excess energy.

I'm here to do LENR/Cold Fusion calorimetric experimentation and data sharing.
I'm not here to debate with people.
I've actually found this whole thing draining.
After this feed I won't be getting sucked into non-sense discussions anymore.
Good luck with harnessing your LMD waves, I sincerely hope you guys figure it out.
I have to focus on simpler, less exciting, but more real things.

I will make a topic for Electrodynamic Waves, Scalar Longitudinal Waves, or whatever you wish to call them. We should keep this thread on the topic of LENR.
