Building a Better Tin Foil Hat

LessEMF also sells shirts and cell phone covers to accomplish the same thing."

      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...

    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.

      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.
