Putting a phone is a simple Faraday cage might prove that the material is effective, it doesn't prove that you need to put the phone in the bag.

I don't have to put the phone in a bag. I can just turn it off.

There is a misunderstanding. In my experiment, the phone is just a detector. I put the phone on my kitchen table and get, for example, four bars. I wrap the head thingy around it and peak in to see how many bars. Does the head thingy attenuate the environmental radiation? Curious minds want to know.

 

Don't need to spend money on this. I just use a layer of aluminimum foil wrapped around my head. Works great! Don't hear any more voices in my head!

Curious minds are into Teledildonics. You need those four bars for the right connection.

 

I'm still hoping for a technical analysis ...Could someone please have a go ....

Suppose we have Mary loo as in the first photo , with her hoodie on ( woven with strands of silver / copper) . She's standing 50meters away from a 20meter high phone mast emitting EMF with wavelength around 15cm .... what effect would the hood have ???

 

​

what effect would the hood have ???

For all practical purposes... none whatsoever

The real question is?

You are asking a question for which there is no answer and no reason to ask in the first place. RF is non-ionizing radiation and does not cause cellular changes like X-rays, Ultra Violet or gamma rays. RF at a sufficient power level can cause damage due to heating of the tissue. e.g Microwave oven. I won't say the probability of damage is nil but it is negligible.

You also don't include enough information:

1. How much power is available at the antenna?
2. What is the antenna gain?
3. How effective is the attenuation of the hoodie?
4. Is she facing toward or away from the antenna?

You need to consider how a Faraday cage works. (look it up on the internet) It is usually completely sealed to prevent RF from entering in any direction. In order to do this you would need to cut Mary Loo's head off and sew the hoodie closed. This negates the intent of the experiment since Mary Loo will no longer care if the RF is having a detrimental effect!

By the way, you get more RF energy from the sun when walking across a parking lot. People who are concerned about cell phone radiation should be more afraid of their own shadow. (a distinct shadow means lots of solar radiation.)

Finally... a straight to the point, non-snarky explanation to a question that a high-school educated grown up should know the answer to, but that deserves to be addressed, nevertheless.

I disagree strongly.

These types of things don't deserve any explanation as they are totally non-scientific scams designed by people who are experts at running non-scientific scams. Snarky answers to film-flam scams are totally appropriate and any other type of answer gives more than the worth of the useless scam product.

Very true. And question #3 is particularly vexing, as it would require a HUGE amount of analysis and a LOT more information (the exact composition, diameter, spacing and orientation of the conductive fibers; whether and how they are connected together; the precise shape of the hoodie when worn; the exact size and shape of the face and neck openings; and on and on and on) in order to predict what the effect of the hoodie would be. And even then, the analysis required to make that prediction would be difficult, complex and time consuming beyond belief. Which is why, when faced by a problem such as this, we almost always resort to the expedient of simply measuring the effectiveness of the shielding with a calibrated RF source and a calibrated field strength meter.

So if @oz93666 really, really, REALLY wants an answer to his question, he needs to buy one of the hoodies and the necessary test equipment, and do the measurement himself instead of pestering us with questions we cannot possibly answer.

The only thing I can predict with confidence is, Mary Loo's bank account will be debited the cost of the hoodie, with no discernible benefit.

I believe that they deserve one good answer, and just that. On the one side, a refusal to answer anything at all would encourage flim-flamers to claim that a conspiracy is taking place, but on the other (and here I'm siding with you) answering this sort of thing again and again normally leads to a never-ending bottomless pit of circular reasoning from the OP. Maybe that's why discussing overunity is forbidden in this place...

When someone is hell bent on believing something against all available evidence and reason, that marks the end of any possible civilized discussion ... it is then that snark becomes the appropriate response.

 

Do they work ?
An impossible question to answer, but here goes.

Radio waves are just that, waves, comprised of an electrical ( Em ) and a magnetic ( Hm ) component
This item looks like its an attempt at a farady shield,
which is a well understood means of screening electrical devices from Em, but zero inherent Hm.

There is a great demonstration of Farday shielding at MIT / Boston museum
https://www.mos.org/live-presentations/lightning

The clothing with metal in , is acting the same way,
as to how well, is a good question, as you say, any holes in the shielding let radio through,

technically they need to be earthed do do a real good job of attenuating,
but thats another story.

Of interest, we use similar gear in the industry to minimise static, I wear at work a one piece, hood, gloves , face mask, shoes that all have conductive fibres woven in, so that all the body is at a constant potential.

And I can tell you, they sweat like mad, ..

I try to poison the well on these types of questions here and elsewhere so they go into the great Internet pit of searches next to questions about unicorn tears being an effective cure for toe nail fungus instead of being indexed next to valid questions about EM shielding.

But, the tears really do work.

 

Psssstttt... wanna buy some aluminum foil

 

Psssstttt... wanna buy some aluminum foil

Only if it's black market stuff not the usual type that's been disabled by 'them'.

 

I was always taught, and all my experience has shown that a wavelength related length is needed for an antenna.

But some have got some amazing results using relatively small crystals.

In the future we might be able to construct tunable crystalline materials. Maybe even weave them.

Maybe even a tunable foil.

In 1700, the thought of thousands of people, daily flying between cities around the world, would have seemed farcical.

Things change fast now-a-days. Just look what the cell phone has done in the last 20 years.

The next age will be the true age of alchemy. Where it all started.

Don't worry nasa , I'm not a believer .... I'm not going to buy one . The question arose on another forum about tin foil hats , there was a suggestion emf could get inside and resonate , amplify .... I don't know if that is the case.

Indeed, it is definitely not the case...
