Why aluminum stocks are always a good bet

[Scooter]

Because there will always be an neverending demand for tinfoil hats:

It didn't take long for the Internet to start buzzing with conspiracy theories after the Social Security Administration posted a notice that it was purchasing 174,000 hollow-point bullets.

Why is the agency that provides benefits to retirees, disabled workers, widows and children stockpiling ammunition? Whom are they going to use it on?

“It's not outlandish to suggest that the Social Security Administration is purchasing the bullets as part of preparations for civil unrest,” the website Infowars.com said. (uh, yes it is)

Another website, The Daily Caller, said the bullets must be for use against American citizens, “since the SSA has never been used overseas to help foreign countries maintain control of their citizens.” (does the term "fallacy of the excluded middle" mean anything to you, you stupid twit?)

The clamor became such a distraction for the agency that it dedicated a website to explaining the purchase. The explanation, it turns out, isn't as tantalizing as an arms buildup to defend against unruly senior citizens.

The bullets are for Social Security's office of inspector general, which has about 295 agents who investigate Social Security fraud and other crimes, said Jonathan L. Lasher, the agency's assistant IG for external relations.

The agents carry guns and make arrests — 589 last year, Mr. Lasher said. They execute search warrants and respond to threats against Social Security offices, employees and customers.

Agents carry .357 caliber pistols, Mr. Lasher said. The bullets, which add up to about 590 per agent, are for the upcoming fiscal year. Most will be expended on the firing range.

It's a shame Steve isn't around to comment on this. It would have been fun watching him wind himself up about it.

[MajGenl.Meade]

lol!

[Grim Reaper]

For there to be any point to this conspiracy, I'd like to know how many regular bullets the SSA currently uses each year.

And I pointed this out in the other thread, hollow point bullets have been in use by police for a while now.

[Lord Jim]

Hey, maybe the SSA has concluded that "death panels" are just too inefficient, and they've decided to start mowing down the old geezers wholesale....

Speaking of tinfoil hats -- I saw The Bourne Legacy over the weekend (save your pennies, btw) -- and the hero saves himself from a drone guided missle by the use of a tin plate and some foil, blocking the signal eminating from the chip in his thigh. The scene made me laugh, and also think it would have been great if he put on a tin foil hat, next.

Maybe someone should invite him to join? (Cept I don't know anyone who is still in contact with him.)

[Lord Jim]

Oh, I'm quite sure Steve knows how to find this board if he wants too....

That might actually work if the missle's only guidance is locking onto the signal eminating from the chip in his body. We use tinfoil to reduce electro-magnetic emmissions during prototyping of designs. I don't see where the low power signal from a thing like an implanted chip couldn't be blocked with some metal of some sort. I forget the characteristics of aluminum, but I think it's pretty good (but not as good as copper).

David Faraday ("the great experimentalist") showed that if you built a 'Faraday cage' it would effectively isolate electromagnetic events occurring within the cage from those without.* A 'Faraday cage' is just a conductive net of material which can be effected with a layer of tinfoil.

The movie schtick sounds pretty plausible.

* there are some details which are due to the wavelength of RF radiation vs the mesh of the cage.

Never liked Bourne from the beginning; too much 'suspension of disbelief' involved to enjoy IMO-

After the scene in ID, where;

He shoots a man, throws he and the body over a stairwell; uses the body as a shield from fire; then as a cushion from the fall...

Naaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaah

[loCAtek]

Faraday Cages have to be eternally charged; otherwise conductive materials will just augment signals.



BTW - I'm manufacturing/welding aluminum telecommunications antennas, these days.

That's interesting, oldr...(I always like it when I learn something new.)

I could easily see James Bond doing something like that....

I was hoping that someone would point that out. A metal barrier would work well against high frequency less so against low frequency, being the higher the frequency the more line of sight. Am I correct in assuming that a radiating chip by its nature would have to be high frequency?

I believe that the conductivity of Aluminum ranks in the top five of metals; above iron but below copper which is less that gold which in turn is less than silver. Copper is the most economically feasible conductor, silver is too expensive and aluminum gets too hot.

[loCAtek]

Aluminum does get hot, but it's use outdoors negates that factor, plus it is the least oxidised.

The ignorance of the general public, and most of this board, about simple science is just astonishing.

A Faraday cage or Faraday shield is an enclosure formed by conducting material or by a mesh of such material. Such an enclosure blocks external static and non-static electric fields. Faraday cages are named after the English scientist Michael Faraday, who invented them in 1836.[1]

A Faraday cage's operation depends on the fact that an external static electrical field will cause the electric charges within the cage's conducting material to redistribute themselves so as to cancel the field's effects in the cage's interior. This phenomenon is used, for example, to protect electronic equipment from lightning strikes and electrostatic discharges.

Faraday cages cannot block static and slowly varying magnetic fields, such as the Earth's magnetic field (a compass will still work inside). To a large degree, though, they shield the interior from external electromagnetic radiation if the conductor is thick enough and any holes are significantly smaller than the wavelength of the radiation. For example, certain computer forensic test procedures of electronic systems that require an environment free of electromagnetic interference can be carried out within a screen room. These rooms are spaces that are completely enclosed by one or more layers of a fine metal mesh or perforated sheet metal. The metal layers are grounded in order to dissipate any electric currents generated from external or internal electromagnetic fields, and thus they block a large amount of the electromagnetic interference. See also electromagnetic shielding.

The reception or transmission of radio waves, a form of electromagnetic radiation, to or from an antenna within a Faraday cage are heavily attenuated or blocked by a Faraday cage.

History

In 1836, Michael Faraday observed that the charge on a charged conductor resided only on its exterior and had no influence on anything enclosed within it. To demonstrate this fact, he built a room coated with metal foil and allowed high-voltage discharges from an electrostatic generator to strike the outside of the room. He used an electroscope to show that there was no electric charge present on the inside of the room's walls.

Although this cage effect has been attributed to Michael Faraday, it was Benjamin Franklin in 1755 who observed the effect by lowering an uncharged cork ball suspended on a silk thread through an opening in an electrically charged metal can. In his words, "the cork was not attracted to the inside of the can as it would have been to the outside, and though it touched the bottom, yet when drawn out it was not found to be electrified (charged) by that touch, as it would have been by touching the outside. The fact is singular." Franklin had discovered the behavior of what we now refer to as a Faraday cage or shield (based on one of Faraday's famous ice pail experiments which duplicated Franklin's cork and can).[2]
Operation
An external electrical field causes the charges to rearrange, which cancels the field inside.

A Faraday cage is best understood as an approximation to an ideal hollow conductor. Externally or internally applied electromagnetic fields produce forces on the charge carriers (usually electrons) within the conductor, generating electric currents that rearranges the charges. Once the charges have rearranged so as to cancel the applied field inside, the currents stop.

If a charge is placed inside an ungrounded Faraday cage, the internal face of the cage will be charged (in the same manner described for an external charge) to prevent the existence of a field inside the body of the cage. However, this charging of the inner face would re-distribute the charges in the body of the cage. This charges the outer face of the cage with a charge equal in sign and magnitude to the one placed inside the cage. Since the internal charge and the inner face cancel each other out, the spread of charges on the outer face is not affected by the position of the internal charge inside the cage. So for all intents and purposes, the cage will generate the same DC electric field that it would generate if it was simply affected by the charge placed inside. The same is not true for electromagnetic waves.

If the cage is grounded, the excess charges will go to the ground instead of the outer face, so the inner face and the inner charge will cancel each other out and the rest of the cage will retain a neutral charge.

Effectiveness of shielding of a static electric field depends upon the geometry of the conductive material. In the case of a nonlinear varying electric field, and hence an accompanying varying magnetic field, the faster the variations are (i.e., the higher the frequencies), the better the material resists penetration, but on the other hand, the better it passes through a mesh of given size. In this case the shielding also depends on the electrical conductivity of the conductive materials used in the cages, as well as their thicknesses.
