Your tin foil hat may be of limited use. It can block some

frequencies, but can amplify others.

"What started strictly as “a desire to play with some expensive equipment” ended with surprising results, says lead study author Ali Rahimi, a recent graduate of MIT’s doctoral program in electrical engineering and computer science. Overall, the foil effectively weakened radio waves by up to 10 decibels over most of the frequency spectrum (there were no significant differences among helmet shapes). But at 1.2 and 2.6 GHz—which fall within the band reserved for government satellites, GPS systems and mobile phone corporations—passage through the foil amplified these waves by 20 to 30 decibels. Although Rahimi doesn’t know why the foil increases only those frequencies—antenna design is a “black art,” he says—the implications of the research were clear. “It requires no stretch of the imagination to conclude that the current helmet craze is likely to have been propagated by the Government, possibly with the involvement of the FCC,” the students sagely declared. “If there are radio waves involved in reading minds, aluminum hats aren’t an effective way to counteract them.""



How about lead or some ceramic material for those frequencies? Maybe scrambling the signals could work, but that would mean attaching some electronic equipment to your noggin.
Paranoia is hard work, but hey, it's worth the trouble.

If this guy ever wants to be taken seriously, he needs to settle on either Tin Foil or Aluminum Foil, they are not the same thing!

A properly constructed AFDB (Aluminum* Foil Deflector Beanie) works well at doing something. :sarcasm:

Here's a very funny link: <http://zapatopi.net/afdb/> :evilgrin:

A pen is pronounced pin. I know for science one must be precise in word and action.

I don't think I've ever seen actual Tin "tin foil." I think it's just a left over common name, from an earlier time in American history.

real "tin"sel for the Christmas tree when I was little (mid 1950's). We would take it off and save it for the next year. Tin foil hasn't been tin for at least as long.

tin was used in old recording cylinders.
