Hi Puterman, ATS Readers, Writers,
Just wanted to comment on your statement about a twisted steel cable in essence being a faraday cage.
Actually it isn't.. but your thoughts were along the right lines.
A faraday cage is a structure built around something you want to protect, from an EMP, or Electrical induction.
The cage absorbs the inducted voltage and current and then usually shunts it to a ground, or earth ground. The cage "intercepts and absorbs" the
A twisted electrical cable, by itself will still pick up induced voltages and currents from an EMP. The only way to prevent it from getting into the
cable would be to make it a SHIELDED cable, which is manufactured, but of course pretty expensive too.
The cables whilst in service, or energized even create their OWN fields which can be induced on any cables near them; as in a cable tray at a factory
In these type of situations and applications, you will usually find that the different cables have different "twists per inch" so as not to induce a
voltage or possibly a FALSE signal in an adjacent cable or wire that is sent to some relay on the other end of that wire. Weird I know, but how it is
in like power plants or factories. These cables are also usually the shielded type variety, and every so many feet or metres of length, you tap into
this shielding and run it to ground, so that if any induced voltages or currents try to get into the cable, they are "absorbed" by the shielding,
and sent to ground.
What I did find a bit un nerving was that even though a cable was buried at a depth of 9/10 of a metre, it still got taken out by induction.
I would imagine, or think that would completely depend upon the depth of a cable, but even more so the conductivity of the soil and moisture content
etc of the soil.. composition of the soil, etc.
For example, a soil that is deep red in color and that has perhaps a lot of ferrous oxide in it, (rust), would be a lot more conductive and
susceptible to EMP penetration than say a more dialectric soil.. like CLAY maybe???
Just a thought.. and by the way I don't consider it fear mongering, it is just a fact and a known vulnerability. The more "advanced" a society is
and uses mostly electronic stuff, will of course be more affected than say the tribes in the deep Sahara where there is little infrastructure in
Yes, it is an option that some rogue nation may use someday, (God forbid), to help defeat another nation, or put it back on its heels. Asymmetrical
warfare at its cutting edge technology... It is actually most likely a strategy that non rogue nations would employ.. (But wouldn't using a weapon
like this make that nation rogue as well??)
ANYHOW...lol... if that type of cat ever gets out of the bag, I would imagine it would require and instigate a full blown nuclear response of the more
conventional nightmare scenario upon whoever did the EMP thing..SIGH..
It would most certainly create a very messy world all of a sudden too.
Gee, just think how much money the SOB's could make rebuilding a entire civilization after something like that!!!
(Dark, dark humor) Better hush, might give em an idea to make stocks climb...to 30,000 DOW...lol. OH wait, maybe that would get all fudged up too...
BAD idea, scratch that one for the 1%..lol.
