Building a Better Tin Foil Hat

Posted by ryuzaki0 on from the finally-people-will-stop-staring-at-me dept.

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."

    Don't be silly. Everyone knows the people who did this study 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.

    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.
