So we do not know everything

e  It is articles like this and the following discusssions that make this site so facinating. All of the contributers are learned people, but cannot agree on whether or not the problem can even exist. Go back to early in the discussion and reread Ann R. Thryft's comment. How many things in history were impossible, before they were done?

  So there is something in your field in which you have limited or no knowledge. Does that mean it is impossible fiction? I think it is more likely that when the only tool you have is a hammer, there is a great tendency to treat all problems as nails. The original author had a problem, tracked it to the source and made it go away. I say, "Great job', and let it go. The fact that I do not understand what transpired does not make it a lie.

  When someone tells me to google something, I always wonder which of the 3 million hits I should read and believe. Google is only another tool in finding an answer, it is not THE answer.

Scalar energy is not fiction. Many physicists which I am not allowed to name here are aware of scalar energy. Few engineers understand why constant values are used for AC equations, but not DC.

Many engineers do not understand (or question) why AC transmission lines have all their energy on the outside surface. Cross-country transmission lines have steel cores for strength, since no real power flows through the steel. But DC transmission lines use the entire conductor cross section and suffer ohmic losses over short distannces, as Edison found out. Why? It is the changing voltage of AC that creates a coupling into the surrounding space-time.

Constant values used for some AC equations actually remove the relationship between the circuit and surrounding space-time. Is this property demonstrable? When coax cables are mismatched with load impedances, gain occurs at certain frequencies. All one needs is a scope, coax cable, a load and a signal generator to prove it. All energy has an source. In this case is the surrounding space-time. Surrounding space-time couples into AC power transmission lines couple to. Space-time is the reason scalar energy exists.

Where does the inductive kick from an inductor or relay coil come from when the applied voltage is suddenly removed? How can a coil develop back EMF of about 10 times the applied voltage it was energized with? All energy must have a source and cannot come from nothing. The source of this energy IS the surrounding space-time, and is scalar in nature. Tesla was aware of this source and utilized it.

There's undoubtedly a good reason that few engineers know about "scalar energy."

I would like to propose another theory about the mysterious waveform:  aliens landed.  They visited Earth for one day and then left.  While they were here, they used their zug-zug guns to capture unknown energy sources.

I've been designing, building, and operating military radar transmitters since 1968. The pilot who told you that radar antennas emit "classified radiation" was incorrect.

I hope to see more April 1 articles in Design News. they are hilarious!

Undetected coupling mechanisms are certainly a very rational explanation, and it would have been very educational to understand the exact path of entry. But a system not specificly designed to reject that sort of interference is likely to suffer from it on occasion. BUt the appearance of signals underground is nothing new, cave explorers have been sending signals much deeper underground, using much less power, for many years. 

I recall an interesting "discovery" made and published by a consultant that I was working with. It related to the "instant" travel of an acoustic wave through steel, with very little loss. When I tried to duplicate his results in our lab, using a more sophisticated setup and accurate instrumentation, I was unable to duplicate his results until one of my ground connections failed. At that point our waveforms matched very well. But the signal was arriving by electrical conduction, not by acoustical transport.

From that point onward, every one of my experiments included a reality check, to verify that the results changed if the ground was disconnected. Sometimes we can learn from the mistakes that others make.

So you have this amplifier for neurosignals...  With a band-limited front end.  How so?

The typical amplifier surely did have RF rectification capability if of bipolar design.  Then it is followed by filtering and the audio amplifier - which also are subject to the RF rectification effects.

Your 3 stories underground building consists of a series of steel columns that extend above ground by a height you didn't give.  There will be an energy transference to these columns which will be higher in amplitude the more distant you are from the ground point of the columns.  You didn't say if the building goes lower than 3 floors. 

I don't really see this as all that surprising.  Even though you were 3 floors "underground" you were not 3 floors really under GROUND. 

I've experienced this same emission here in OC in the past (>20 years) from either OC Airport or El Toro, I don't remember which.  Going to FET input op amps along with ferrite beads in a few areas eliminated the signals.

Yes, I agree articles like this that make their way to this forum do harm to EDNs credibility. Even before I read the Comments section, I had to peek at a calendar to make sure it wasn't April 1st and someone's idea of a joke. Congratulations to jlbraun and jfowkes for being the first to bring the bright light of reality to the post.

A simple Google search will reveal a great many characteristics assigned to this 'energy' with fantastic claims of free energy (zero-point energy), unlimited energy, healing the body of all disease, universal healthcare and best of all, the 'energy' exists in a "4-dimensional realm" and is "shrouded in secrecy". The conspiracy theory sites are thick with these claims and strangely enough, there are not any scientific or academic websites backing up these claims with verifiable, testable, experimental or peer-reviewed data.

Most of us probably have decades of experience and education and still have not seen, heard or measured these fantastic effects before. If it has been around forever, and its secrets decoded by Tesla and others, why wouldn't industry have taken advantage of it by now? Isn't it more likely (Occam's razor) that the propagated microwave signal, transmitter, or power supplies coupled the bipolar signal into the sensitive underground amps by some other simple means? And regarding the signal's coincidental or mysterious disappearance, how many forum posts in the recent past conclude with something like closing a hatch, door or access panel to attenuate the offending noise?

Yes, Scalar Waves are woo. A few minutes on Google will confirm that. (If yuu're sceptical about the veracity of google results, be more sceptical about scalar waves).

Forgetting the physical reasons why they're woo (see below post), there's a basic economic argument. If they were real, someone would have made money out of them by now.

I too feel that this particular story diminishes the credibility of EDN.

"Scalar" waves are the product of Bearden's fertile imagination.

"Scalar" waves are simply waves as presented in the reactive near field where E and B are out of phase as the energy in the antenna couples to 377 ohms of free space and they come into phase as a normal propagating wave.  No new extensions to Maxwell are needed.


(and the solutions to Maxwell in far field have E and B *in* phase, not 90 degrees out of phase as this article - they are out of phase in the *near* field.  Such an elementary error is disappointing.)


Similar "scalar" waves are present in transformer coils and capacitors, which can be considered as 2 antennas very close to one another in their near field.  One can hardly say that the operation of a transformer or capacitor requires "scalar" extensions to Maxwell!


SLF/ELF/LF/VLF below 300kHz is regularly used to communicate with submarines, as they can penetrate hundreds of meters of water.  In the case of ELF/SLF the *entire planet* is in the near field so E and B are going to be out of phase. 

Here's a neat pamphlet on it from the FAS.  You just need very big antennas, good ground coupling, and LOTS of power to overcome the fact that your transmit antenna at 46km long is a tiny fraction of the wavelength.

http://www.fas.org/nuke/guide/usa/c3i/fs_clam_lake_elf2003.pdf

The receiving antennas on the subs for SLF/ELF/LF are simply small loops of wire - pretty much transformer coils - or very long wires unspooled from the fantail.  If you have loops or planes or lines in a low frequency circuit that happen to be oriented the right way, those can pick up LF in the nearfield, at 2 miles you'd be in the nearfield for anything under 100KHz and could easily pick it up underground.

Here's a good explanation of why "scalar" waves are simply nearfield.

http://www.capturedlightning.com/frames/Non-Herzian_Waves.html

And yes, you can shield just fine in nearfield of LF/ELF.  The reason people say "ZOMG you can't!" is because they can only conceive of shields as grounded metal boxes, which if you have a nearfield emission coming from current loops (which most of them are - AC motors and things), its emission will zip right through a grounded metal box around it as it induces a closed current loop on the box instead of trying to pull charge from ground.  The reason you so rarely hear about LF EMI is that very few people operate sensitive circuits in the tens of hertz range, and if they do, they are likely in a commercial product and are well shielded against powerline frequencies anyway, so it's only the hobbyists and researchers running ELF stuff on the bench that run into this.

Instead, you can use lossy ferromagnetic materials, I have a box full of little stick-on lossy ferromagnetic buttons and flexible sheets that work very well for shielding against LF in low frequency analog circuits.  In fact we used one last year to shield a sensitive opamp circuit against a 180Hz emission from a 3 phase AC motor driver - just squooshed a little thumbnail sized piece of the stuff over the feedback loop area on the PCBA and the spurs disappeared.

It's made by these guys.  http://www.magnetic-shield.com/


Go tell your neuroscientist about mu-metal magnetic shielding.  It will fix their problem.

ELF is fascinating stuff, don't pollute it with this woo "scalar" business.

I wouldn't like to comment on the science behind scalar waves as I simply don't know enough about the topic, but I can vouch for the ubiquity of radar signals when close to the antenna.  A while ago I wrote about my own experience ("Earth Station had a Screw Loose") where just a simple mistake in assembling waveguide allowed airport radar signals to break into satellite receive channels.  With peak powers often in MW range, even attenuation through concrete might not shield really sensitive gear.  Also, it's amazing how even the best circuits can exhibit unexpected properties when operated outside normal limits - hence unexpected demodulation perhaps?

I'd like a pound for every time I've come across an odd effect and reflected that if I'd set out to design a circuit to do that exact function I wouldn't have known where to start, yet I've accomplished it by accident.  It happens less now that I use circuit simluator software though, so I'm not really hankering for the old days!
