Love the tempest and faraday cage stuff

[devanshoom]

faraday cages eh? and I thought I was the one who was paranoid

if the human race ever gets to the stage where they have to exist in a series of cages then they may as well throw in the towel.

[Navck]

... Just me but adding an electrically conductive "shell" around a room sounds like it'll add to the expense of construction greatly. Also something about screwing with devices that need radio communications (Phones, laptops and all, you know?).

But seriously, the first step people need to worry about is to not leave blatant pieces of information about their selves on the internet. Don't believe me? Go check out how trolling works at imageboards and how people's "dox" (Personal information) get obtained. Most of it comes from when the "victim" leaves little tidbits on the internet that tie together their real life information. A little searching later they get an address off a phone number.

All the Open/Closed OSes, Online Transactions, Ultra Government Conspiracy and other items should come after that first step is closed.

As for me, I still kick myself for not beating up an ex-friend for registering under my internet alias and put a few posts on websites and forums up acting as a jerk/unwarranted self importance/exaggerated fandom toward certain subjects when I was much younger. Namely because those could lead back to me one day. (And this is why he is an ex friend)

The electrical wiring circuit in most UK buildings creates a Faraday cage without the need for any paranoia.

If you have three wires in each cable (live, return, and earth) and the earth wires all go the circuit board then the cage is complete. Keeps out all sorts of nasty things such as lightning.

Cars are Faraday cages since they have their own electrical circuit where the chassis acts as earth. Safest place to be in a thunderstorm.

I am no electrician but it seems sensible to me.

No. Its nowhere dense enough a mesh to form a Faraday cage in any useful sense.

Any gaps in the mesh have to be significantly smaller than the wavelength of any radiation that should be blocked.

Cars are Faraday cages since they have their own electrical circuit where the chassis acts as earth.

The electrical circuit in an automobile has nothing at all to do with what happens when there is a direct lightning strike on an automobile.

Safest place to be in a thunderstorm.

Not the safest place by any means, especially if conditions are wet.

I am no electrician......

That's very clear

[Temetka]

Thanks Bill I was going to clear that up but you took care of it handidly.

[Temetka]

I can no longer sit back and allow Communist infiltration, Communist indoctrination, Communist subversion and the international Communist conspiracy to sap and impurify all of our precious bodily fluids.

What I would be more worried about is how everyone leaves a little virtual paper trail behind about who they are, where they live and their phone numbers... Basically, social networking and unguarded behavior will nail people way before Orwellian style super surveillance.

Not everyone.

[Navck]

Not everyone.

But too many to list.

anyone ever heard of "internet 2"? Google seems to be up to no good again......

Ok,

who broke my image tag and why?

[JaneL]

I broke it because it was large and animated.

[Temetka]

I broke it because it was large and animated.

The generals picture is 500x278 pixels.

Mine is 480x360 pixels. So it is a little shorter than the general and a tad wider.

Roughly, the 2 are equal.

So you broke it because it was animated?

Wow. Ok then.

[TTY]

Roughly, the 2 are equal.

The size of the picture of the general is 42 kB, the size of your picture is 505 kB. This forum's rules of the road allow pictures up to 50 kB.

[Temetka]

Which was not mentioned as one of the reasons the tag was broken. Unless I mistaken she was referring to the dimensions of the picture and not the file size.

[Temetka]

Not that it really matters anyway, it's just a picture that I thought went in line with the quote and picture from Dr. Strangelove.

[JaneL]

You are mistaken. Why was LARGE unclear?

[Temetka]

I assumed you were referring to the dimension of the picture.

I stand corrected.

I thought I put in a reply to Bill Bolton and Temetka the other day but it doesn't seem to have registered. OK, so you have the clever clogs on the subject of electrics. I did say I am not an electrician. Unlike others, I never pretended to be.

It was a qualified electrician who, on inspecting my household wiring for insurance purposes, said that I needed my oil tank pipeline to be earthed to complete the Farady Cage and then went on to explain the physics.

It was an American who is a car electronics expert who told me that cars are Faraday Cages.

So both of them were wrong, and I am wrong for listening to them.

However, you are both correct ... of course.

That sounds like a pretty good summary, actually.

You didn´t read it carefully The first technician is probably wrong (unless your house is built out of cables and/or metal plates) -> http://en.wikipedia.org/wiki/Faraday_cage

The second one is right, but the reasoning you mentioned earlier in this thread was wrong. The fact that cars are Faraday cages has indeed nothing to do with the wiring as already mentioned by Bill Bolton.

Interesting link Marin. Apparently, killer was right about the most important thing: the tin-foil hat crowd is onto something.

A Booster bag (shopping bag lined with aluminum foil) acts as a Faraday cage. It is often used by shoplifters to steal RFID-tagged items

That's very interesting, because you don't need to fabricate a shopping bag lined with aluminum foil. You can buy them for a buck or so at almost any supermarket in order to keep your frozen food frozen or cold food cold. I have one right here as a matter of fact.

Maybe if I put it on my head I can think better. But I was wondering if shoplifters are getting away with stealing around here because one of those would not be noticed as easily as a home-built contraption.

The tin-foil hat won´t work for the proposed purposes because it won´t be a closed surface (!). You actually need at least a tin-foil helmet to make it work. However, in that case it may cause undesired interference of your alpha-waves...

Unfortunately, tin foil is quite ineffective in terms of providing protection from gamma rays.....

Right, that is what sunglasses are for

Though, when the right time comes to be concerned about such amounts of gamma rays, you wouldn´t want anything melting on your head/face...

[devanshoom]

while you were all discussing faraday cages, a new senate bill has emerged, BILL S510......a bill that will ban you the people from growing your own food.

Well, they can write and propose the bill, but passing it and implementing it are two things that are not going to be as easy as it may seem to you...

[craigmontHunter]

The second one is right, but the reasoning you mentioned earlier in this thread was wrong. The fact that cars are Faraday cages has indeed nothing to do with the wiring as already mentioned by Bill Bolton.

Cars are Faraday cages like airplanes are - they disperse the charge placed on them (like lightning), and it follows the path of least resistance. That is why when you are getting out of a car hit by lightening, you cannot touch the ground and the car at the same time, otherwise you will complete the circuit. In the case of planes, the charge is distributed over the skin to the static wicks on the wing and the tail where it is dispersed into the atmosphere.

Edit: After thinking more, the first part is correct as well. The oil pipe is a Faraday cage, so that if a large electronic charge (lightning) hits it, it will be dispersed through the pipe and down the grounding wire, without creating a spark, which is bad to mix with oil. The pipe is a faraday cage, the house is not.
