So why is placement critical? It still should not matter where in the room this item is placed. I had someone the other day tell me AA members are placing 5 and 6 of these things along and behind the speaker to excite different room nodes to voice the soundstage....that doesn't make any sense.

Alan, I don't have one but from the pictures and description this thing generates a LF magnetic field and the effective radius of it's antenna is fairly small. Beyond one radius on axis, the signal will decrease with the third power of distance. Very fast. At the sides it will drop off closer to the distance squared. Bottom line is it's a lot stronger when you get closer. Since the frequency is so low that it won't see any normal walls and so will not reflect at all.
I think there is some confusion caused by Geoff, as usual. Couldn't resist. Anyhow he's trying a CD that apparently does a similar thing to your brain by generating a beat frequency between a couple of audible tones. That of course would tend to bounce around and be heard throughout the room at various levels.
As far as making sense... Well if it affects mostly the mind it seems like you'd want to wear it as a beany. Maybe if the propeller turned at just the right speed...

Rick you should patent that battery powered beanie cap version. To me the mere notion that these little tin foil voodoo shaped antennae need to be extended on to that much maligned electrical distribution network in order to do such supposed good works is a little hard to take. The most interesting part of the FAQ to me was:
"A gauss meter measures the field strength of EMFs. Most homes will have a .5 to a 2 milligauss background EMF field. EarthCalm products work to ground you thereby allowing AC induced currents in your nervous system to dissipate. They will not change the milligauss reading of the EMF itself."
Thus I would assume that when you get within a foot or two of that old 36" CRT you just can't throw out yet, all bets are off...
I wouldn't put too much stock in explanations. A bogus explanation isn't a reliable sign that the effect doesn't exist. Perhaps they mean grounded more in the new age sense than the electrical one.
I take it that these things act directly upon our nervous system, for good or ill. Perhaps they reduce mental jitter by providing a stable clock signal... I'm a little leery of deliberately messing with our body's electrical systems for entertainment. As a youth I enjoyed visiting an old museum that included a large (and operative) display of machines that were popular in the early days of electricity. For a mere nickel you could hang onto two handles and electrocute yourself, or by holding hands, your friends also. The more you pulled the handle, the higher the current. Lights indicated how much of a man you were. Some were reasonably isolated and safe, others just a rheostat across the line. But the effect was felt by all!
