" Silica Disks in EMF Protection & Balancing Tachyonized Silica Disks raise the life force potential of anything placed on them, so they have a wide range of uses including:
Circuit Breakers
Studies show that Tachyonized Silica Disks installed over your circuit breakers neutralize the negative effects of EMFs, protect your circuits and, at the same time, improve biological functioning. Food prepared with electrical appliances will have greater life-force energy.
The flat, round Tachyonized Silica Disks need only be placed over your circuit breakers to take effect. Use the pouch that comes with the disk for easy installation. NOTE: Tachyonized Silica Disks must cover all the breaker switches in order to be completely effective (small dwellings, like one or two-bedroom apartments usually need two 4" Tachyonized Silica Disks, larger spaces generally need three disks or more). Once installed, you no longer need to think about them. The Tachyonization process is permanent. "
i like my tachyon disk. i just use it on my person or to energized stuff like water and lately, iodine.
speaking of iodine, we have some interesting data that Iodine helps to protect the body from the effects of EMF. you probably need it anyway.
