Materials that absorb RF energy

[wgscott]

If I said I had a box I could put in a room that would absorb the ambient visible light, and make the room darker (apart from casting a shadow), everyone would say it was total B.S.  If I came back with some reports that people who had tried my boxes indeed felt the room was not as brightly lit, those anecdotal reports would be dismissed as delusional.  

 

The difference here is only the wavelength of the photons, but the claims are completely analogous. 

 

The admonition "you can't be sure unless you try it" amounts to saying "you can't be sure physics is right unless you check for yourself". The box advocate can only be right if Maxwell was wrong.

Barrows says "Dark Matter is a passive device which damps RF energy fields" and that "it acts on RF energy which is present in its vicinity." The only logical interpretation of these statements is that it somehow sucks in the badness around it. The placement suggestions also seem to be based on such a notion. And then there's the negative ion nonsense.

 

I've re-read the post about "Dark Matter" and it comes from @vortecjr not @barrows ... best I can tell Jesus is the marketing guy? No doubt the marketing description is a painful mischaracterization of simple absorption but barrows doesn't himself use this language ... I mean green magic markets interact with photons in their vicinity also...

The quotes in my post that you quoted were from later posts by barrows.

Ok and to clarify my above post NO green magic markets DON'T operate on photons in their vicinity (in case my sarcasm wasn't caught).

 

Vicinity of a location does not mean at the location, it means near the location. RF absorbing materials do NOT absorb RF near the material, only at the material.

The paint they put on Stealth planes absorbs RF energy and is allegedly very fragile.

Honestly I do not remember so many gadgets in the analogue era ...!

 

Is the digital era that led us to this, from its very bad beginnings?

 

I'm not saying that none works, but ...

 

Or @AudioDoctor , “We are buried beneath the weight of information, which is being confused with knowledge; quantity is being confused with abundance and wealth with happiness. We are monkeys with money and guns.”

 

Or both ?

Roch, perhaps replace "knowledge" with "Wisdom" and it will become more clear what I believe the intent of what Tom Waits is saying here.

 

edit:  I have added a good example of the difference between information, and knowledge or wisdom.

I would say that we now live in a world with much more RF/highish frequency radiation all around us, from a proliferation of radio signals and digital devices.  AC lines in particular are loaded with high frequency noise, consider that most electric components have processor chips inside them of some sort.  Think  washing machines, etc, etc, etc...

 

All these noise sources add up and can interfere with audio systems attempting to produce the best sound quality possible.  In the "analog age", most electronics in the home, and indeed in use, were also "analog" in nature, wihout highish speed digital circuits, and we did not live in a world with a grid of cell towers everywhere.

I would suggest it is not digital audio which is the cause of the issue specifically, it is digital everything.

I agree with you. Everything digital began at the same time ...!

 

That's why I'm trying to get my cardiologist not to install a pacemaker for my heart. First I need to be sure that Everything digital does not interfere with the same ?

 

Out of thread (but closely related), I had my powerful WiFi router very close to my body for long sessions. Since I moved away enough my heart rate stabilized, after doing it for 6 months.

(Well at least the kid got the answers to the other two questions correct.)

Why were you doing that?  Were you part of that experiment where they turned homeless people into WiFi hot spots?

Because it was there all the time, I just forgot it, it was part of my home box office ...!

 

Never, no doctor asked me that, when I started with the arrhythmia. Now I'm careful as far as the Cel Phone is ...

 

The bad thing is that I lost communication with the spirits and the alien ?

[barrows]

I often wonder, if in twenty years, we will have invented a new way to communicate which does not use airborne radiation, and we will look back on the present times and wonder how stupid we were to be living in an environmental soup of man made radiation, which made everyone sick...

I can just imagine a young person of the future saying to me: "you mean you held up that cell phone thing to your head, even though it gave everyone brain tumors?"

Unbelievable...

Just clicked on this thread (read some of the other one also) and learned of this "Dark Matter" product. 

 

1) OMG

 

2) We desperately need an Audiophile Consumers and Technical Union to move the Overton Window of this "hobby" somewhere, anywhere, but here.

 

3)  I want two.  The first is to be a Borg Cube.  No cheap paint or sticker job either, I want it to have the texture of a Borg Cube with a button I can press that will of course say "resistance is futile".  The second is to have a vacuum tube socket formed into it with a choice of either cheap current Russian tubes or an upgraded NOS option... 

[Ralf11]

Let's not get all crazy here.  If the DM contains RAM, then putting it in between an RF source and X will absorb RF, preventing some of it from impacting X.  If X is ... um... invariant to RF it won't matter however.  If X is affected by RF it will, so long as the delta in effect on X make a difference in SQ of the entire system.

 

I am still trying to figure out a way for something in a box to absorb non-impinging light in a room -- a nice singularity would do it, but then there is no box, no room...

Good luck with that. As long as there are people eager to be deceived, there will be no shortage of charlatans to oblige them.

True, but the point is not to "fix" this (that would be a fix to human nature) but to move the boxes (of whatever:  sand, rocks, water) from the neighborhood of "Policy" and "Popular" closer to "Radical"...

A cubic inch of neutron star material would probably be enough to do something. If you could stop it instantly burrowing its way to the centre of the earth.
