The Aurificusian Hypothesis

[J_Player]

From what i understood,,Esteban said that the IR leds are just a way to improve the radio detection, not a detection system by itself.

I wonder what is the local effect of a IR beam in a voltage gradient...

Hi Fred,
The average voltage gradient in open air where Esteban uses the IR LED is 100v/m, but can be up to 300v/m, or less than zero. But on normal fair weather days will average 100v/m. According to LRL theory this gradient is much reduced locally above a long-time buried metal object, which could be the basis for the variations in the power pulses of an IR LED if it's power use is influenced by the voltage gradient where it is illuminating.

If you want to experiment with this, you could create an artificial local gradient using a high voltage source such as a neon sign transformer with rectifier and some metal plates and shielding. ie: build a semi-closed Faraday cage that has a controlled voltage gradient inside which can be adjusted to different amounts than the surrounding atmospheric gardient.

It is possible the IR LED is not responding to the local voltage gradient anomaly, and the fluctuations in the power pulses are caused by something else. Some voltage gradient experiments could help determine if this is the case.

...The idea, as explained, is not completely non-sense to me... the problem is , also supposing that weak current flow around target possibly exist, that the current flow will create just a too weak magnetic field to be detected in any way... cause of the power of 3 attenuation of field strenght with distance.

The order of magnitude I see this stuff is the like you can have making e.g. a simple bimetallic turn and expose to sun... say copper/zinc stuff 30cm diameter... now... if you'll place a good compass in the middle you can (maybe) get a small deviation of needle if enough magnetic force is generated.

But , then, even if this experiment work... it's very different than e.g. thinking at a visible/measurable deviation of compass needle from 10 meters away... also the copper/zinc is an ideal case... and e.g. a gold target in soil matrix is quite different stuff.

...An interesting aspect of this stuff could be that a good/interesting test could be made with a very sensitive magnetometer... if the current really develops as described the magnetometer held just over the buried target could maybe locate the target even if out of range of common MDs.
Would be impressive e.g. detecting a coin at 1meter deep!
But, of course, just theory... I didn't made any experiement to confirm that... nor I'm not sure the things are like exposed... and the current really exist. Just ideas. (btw I haven't handy any mag at now to test)

This is easy to test with a US penny. US pennies are made of zinc with a copper outer layer. If you cut one in half, you can see the zinc core layer inside the copper shell. You could put a US penny in the sun and hols your magnetometer above it to see what effect you detect in ideal conditions. You could also arrange the penny so half of it is shaded, while the other half is in the sun from different angles to see if this makes any difference. Also try cutting the penny into different shapes to see if this makes any difference. My guess is you will detect no magnetic change that does not exist with the penny at a stabilized temperature throughout.

This will only serve to demonstrate that there is or is not a flow of current in the penny in the test condition. Of course, we do not expect a flow of current when no load is connected. So we can connect a sensitive voltmeter to see how much voltage the penny has aquired in it's thermal gradient.

If this test thermal gradient voltage test shows nothing conclusive, then we could try a third test by cutting the penny in half and carefully connecting a Schottky diode to the zinc core, and the other lead to the copper shell. When repeating the same experiments in different lighting conditions, you can see if you can detect any pulses of power moving through the diode. Any pulses are sure to be sensed on a magnetometer, or even a small coil nearby connected to an oscilloscope.

Hi,
I don't belive in the EM pulse generation described by Aurificus but the experiment with two conductors, not only the penny stuff, but e.g. two wires of different metal like copper and zinc (or also some iron) could give some result if there will be some thermal gradient in the shorted turn.

If so... a simple sensitive galvanometer for that stuff... (I still have it in garage,hopefully) will read current even really small, if there is. No need of amplifiers etc... will just add noise in this case.

My instrument is old style... wood and glass made and can read maybe 10nA at end of scale!

Thompson like! Thompson era ? Thompson owned that ???

Maybe is from 1910... museum grade

Maybe I can read the dang current... if there is...

Kind regards,
Max

Experimental devices

Still all this talk of thermistors, bi-metal contacts, closed loops etc. etc.
all very standard, conventional stuff and well known (c1750-1915) to produce very small phenomena.


The 'Experiment' will require a metal conductor 'encased' in a large semi-conductor to create a fully enclosed Schottky type barrier.
The contact between conductor and external media will need to be "very" close, ie. with some electron sharing (like..say.. long time "buried")

Energy source will be a thermal gradient between top of media and bottom.
Energy transfer into the metal will be greater than transfer out, leading to an increase of the internal energy.
This will excite electrons in the metal and cause them to seek the lower energy areas at the lower boundary surfaces.(charge carrier diffusion)

They will be held at this surface by the increasing energy level behind them. They cannot transfer their energy out quickly due to the lower temp gradient at the bottom compared to the top and they are trying to transfer energy to a low thermal conductive material by phononic atomic vibration (slower).

They will also create a voltage potential across the barrier by displacing electrons in the semiconductor medium. When the potential has reached the forward voltage requirement (say, .2 -.5V for commercial Schottkys, who knows for this?) a current will flow across the barrier. It is a function of the Schottky barrier that the switching takes micro seconds.

The current might be small but is extremely quick resulting in a brief but intense pulse of EMR maybe several mW. or even more, possibly quite detectable from a distance.

Question is... how to build such an experimental device?

They appear to be rather rare and hard to find in nature!!
And the exposing of a potential find destroys the "structure".

Remember also that, the introduction of wires between separate elements
with different temperatures and crating a circuit will produce their own voltage potentials by Seebeck/Thompson/Lord Kelvin .... Thermoelectric effects.... which may negate the potential required for the device to function.

Phew,
Aurificus

PS. This is just a theory to explain a reported phenomena no need to "git all het up"

[Aurificus]

Reverse recovery time

The most important difference between p-n and Schottky diode is reverse recovery time, when the diode switches from non-conducting to conducting state and vice versa. Where in a p-n diode the reverse recovery time can be in the order of hundreds of nanoseconds and less than 100 ns for fast diodes, Schottky diodes do not have a recovery time, as there is nothing to recover from. The switching time is ~100 ps for the small signal diodes, and up to tens of nanoseconds for special high-capacity power diodes. With p-n junction switching, there is also a reverse recovery current, which in high-power semiconductors brings increased EMI noise. With Schottky diodes switching instantly with only slight capacitive loading, this is much less of a concern.

OOPS! Sorry, Switch time down by X10,000. Output power up by....X10,000
or current required, reduced....x10,000

Better to use bio-sensor like "Girl's Are a Diamonds and Gold Best Friend". There are no problem with reverse recovery time. All you need is only to look occasionally at here eyes. If the spark gap out then diamonds in the soil, but if something glow there is some gold.

That's why it's a good idea inviting some pretty girl at LRL tests in the woods...

I mean... if your LRL don't work... you can use the girl... to locate stuff... or , if also this fail, at least could have some alternative to hearing that boring randomic beep beep...

and focus on some other topic...

Choose carefully, or you will hear randomic noise all the same but there is no on/off switch...
...Or is there?

Maybe you need to listen to random noise, but it is a time-proven fact that women are excellent for locating gold and diamonds.

Carefull to choose the right port at the right time, or you may create a short circuit .

Ideed... mistakes are possible... and LRLs are of no help in that...

In the absence of "contrary, Technical, discussion" we may consider the emission of small Rf pulses from "long buried, metal objects" to be Theoretically POSSIBLE!

Certainly.

As theoretically possible as; the remains of little green aliens stored in the bowels of Area 51, or that the real secret ingredient in all LRL devices is hot melt glue and all the electronic componentry is just a grand diversion, or .......... ...well, you get the idea.

Lots of things could be considered theoretically possible, especially in the absence of overwhelming evidence to the contrary... but at the same time common sense and logic dictate they are also highly unlikely.
