An anonymous reader writes "Now you can wear a Tin Foil Hat and not be subject to ridicule or discomfort." From the article: "This hat -- made from cotten fiber, silver and copper -- will help reduce your brain's exposure to EMF. LessEMF also sells shirts and cell phone covers to accomplish the same thing."

Didn't they know that it's been proven that tinfoil hats simply don't work?

Re:They don't work (5, Funny)

edgr (781723) | more than 8 years ago | (#14963130)

Don't be silly. Everyone knows the people who did this study [mit.edu] were government operatives, to reduce the use of tinfoil hats, so their mind control satelites could get to us.

Don't succumb. Keep wearing it.

Not their fault! (1)

Cmdr-Absurd (780125) | more than 8 years ago | (#14963813)

Not their fault! They didn't KNOW they were governement operatives.
The governement was influencing the study through RF based mind control. They made them see results that were contrary to reality.

That study is misleading, since it uses aluminum foil, not tinfoil.

Re:They don't work (1)

Feneric (765069) | more than 8 years ago | (#14969485)

While I certainly don't claim to be an expert on such matters, even I can point out the obvious flaw in the study -- it's focus on radio waves. I only ever knew one character who wore foil hats, and he didn't even bother with them inside because they were made to defend against the "Orbital Mind Control Lasers" (OMCL) mounted on satellites. They aren't supposed to be providing an (obviously non-functional) Faraday cage around the head -- they're supposed to be blocking the "lasers" via their optical properties. There are supposedly far worse things in public buildings to watch out for that go far beyond the defense capabilities of a foil hat, so "wearing the foil" in a public building just makes you look silly without providing you with any real protection.

I can only assume that the lasers supposedly use a wavelength in the near ultraviolet, but I've never really dug into it... Now that I'm thinking about it a little though I suppose that the next time I run into this guy I'll definitely have to quiz him about some of the details on how the OMCLs are theoretically to work... He (believe it or not) has a solid technical background so the answer may be interesting.

sumday (888112) | more than 8 years ago | (#14963147)

Yeah, but who funded the research? I'm going to assume it must have been the US government and/or various large corporations, all of whom have a vested interest in polluting your brain with mind-control electromagnetic EMF wave thingys for their own profit... or world domination... something like that... whatever.

The horror! (5, Informative)

Frozen Void (831218) | more than 8 years ago | (#14963362)

http://en.wikipedia.org/wiki/Tinfoil_hat [wikipedia.org]
The effectiveness of the tin-foil hat as an electromagnetic shield for stopping radio waves is greatly reduced by the fact that it is not a complete enclosure. Placing an AM radio under a metal bucket without a conductive layer underneath demonstrates the relative ineffectiveness of such a setup. Indeed, because the effect of an ungrounded Faraday cage is to partially reflect the incident radiation, a radio wave that is incident on the inner surface of the hat (i.e., coming from underneath the hat-wearer) would be reflected and partially 'focused' towards the user's brain. While tin-foil hats may have originated in some understanding of the Faraday cage effect, the use of such a hat to attenuate radio waves belongs properly to the realm of pseudoscience.

WTF? The Tin Foil Hat (TFH(TM)) is not used to block AM (low freq. - ground based transmitters) from getting into your brain. The TFH is for blocking Mind Control Rays (MCR(TM)) (microwave - satellite based transmitters) from getting into your brain.

I know that a tree, which is not a Faraday cage, will block my satellite TV signal. The TFH must block signals from above as well as a tree!

Not that I believe in the whole TFH/MCR thing but please use proper scientific procedures when debunking "pseudoscience". Otherwise you will just give them more to be paranoid about.

Well,As for usual EM radiation it can be used as crude mind control by transmitting it to a special device called TV and making the people watch the screen of device.
imagine that,turns out most people never suspected it and never stop watching merely switching the channels at which Mind Control Radiation (tm) is transmitted.
The Cartoon Network is particuraly effective at destroying brain cells,literally training the next generation of drooling zombies for evil mind control overlords.

Schumann resonator (4, Funny)

BadAnalogyGuy (945258) | more than 8 years ago | (#14963183)

They are selling something called a 'Schumann resonator'. Schumann resonance is an extremely low frequency (2-20Hz) standing wave pattern observable in the ionosphere. What is amazing about these waves is that they are key to our survival. Much like how oxygen is required to breathe, Schumann resonance is required for life (or at least inasmuch as something like Vitamin D is required). We evolved with these resonances, so we are evolutionarily attuned to them, whether we know it or not.

Modern society bombards us with very high frequency electromagnetic waves that drown out the natural environmental electromagnetic waves that we are evolutionarily accustommed to. Therefore, our health at times will suffer due to a lack of these natural ELF electromagnetic signals.

To counter that, it is possible to buy a Shumann resonator which plugs into a wall socket and broadcasts in the Schumann frequency range. It helps by balancing out the daily hazardous bombardment of modern EM fields with healthy and wholesome natural ELF fields. You can experience better health and more vigor just by having these near you (and turned on!) for several hours each day.

I can believe that someone would be duped by that kind of logical pseudoscience. It all sounds credible to someone prone to neophobia.

A cell phone cover would be useful.... (4, Funny)

Malor (3658) | more than 8 years ago | (#14963333)

Covering your cell phone is definitely important. If it were exposed to RF, it could accidentally function.

Re:A cell phone cover would be useful.... (1)

Myself (57572) | more than 8 years ago | (#14964653)

But these covers don't completely block RF, they just attenuate it a few dB. Introducing loss between the handset and the tower simply means the handset will crank up its transmit power to achieve reliable communication. You'll see less standby time, less talk time, more dropped calls, and more out-of-service time.

Now, if your phone-sock is completely symmetrical, this'll mean your personal RF exposure is essentially unchanged, because the phone will adjust until the tower reports an adequate signal:noise ratio. But if your sock isn't perfect, perhaps attenuating the signal in the phone-tower direction more than in the phone-body direction, then the overall effect will be that your body is exposed to *more* RF.

The same broken logic crops up around those "antenna booster" products: "It's like having a four-foot antenna on your cellphone!" Sure. Because a four-foot antenna resonates perfectly at cellular frequencies, right? Morons. Some of those products *do* cause your phone to display more "bars" of signal strength. This is just like putting your head in a trashcan makes your voice louder. Doesn't make it any easier to talk to other people!

Seriously, cellphone makers love to advertise their inflated standby time and talk-time numbers. An inefficient RF stage wastes power, so it's in their interest to make the most efficient transceiver and antenna possible, thus allowing them to list longer standby and talk times, and reducing complaints of dropped calls. If putting a sticker on the battery really made your phone work better, wouldn't it ship that way from the factory?

Cover for cell phones _increases_ radiation! (2, Informative)

Jump (135604) | more than 8 years ago | (#14963348)

Didn't they take any basic physics class? Putting your mobile inside a radiation shielding cover, will:
  • Make it harder if not impossible to receive phone calls.
  • Increase the radiation power of the mobile even outside the cover, because the power is adjusted to environmental conditions!!!
  • Increase battery consumption.
  • Make you look like an idiot (like those people with magnetic shoes and similar crap).

I was in IBM's Toronto lab buildings last year - amazing: five buildings, each five stories, linked with hallways, and all are fully grounded faraday cages. No cell, am, fm, tv, nothing. They're a bit picky about security, it seems. There are designated areas you can go where cellphones will work. Apparently, the "shadow" of the structure also blocks signals, so you have to get relatively far away from the building or stand in one of the "holes" that have been identified. Nice cafeteria, by the way.

Solid or tiny holes? (1)

SpaghettiPattern (609814) | more than 8 years ago | (#14963789)

Will the tin be solid or will it have tiny holes?
  • If solid, how will the sweat be able to leave your head? Fluid or as vapor?
  • If tiny holes, until which frequency will it filter?
  • Also, if tiny holes, will water molecules (sweat vapor) pass?

tiny holes (1)

Peter Simpson (112887) | more than 8 years ago | (#14964087)

1/2 wavelength diameter, I think. So the size of the hole is related to the maximum frequency blocked.

You can see this in the attenuation (blockage factor) graph at the LessEMF website. As the frequency gets higher, the attenuation gets less, because the space between conductors becomes a larger fraction of the wavelength. Wavelength goes down as frequency goes up:
L (meters) = 300/F (mhz) So, 10 GHz frequency means 15 mm half-wavelength, or about 1/16 inch.

We actually bought some fabric from these guys and tested it to see if a bag made of the material would block cell phone signals. It worked quite well - phone in the bag could not make or receive calls.

Ummm... I'll stick to homemade. (2, Funny)
