SD-3 was developed for a variety of uses including EMF protection, increased vitality in food and beverages, and better sleep patterns. Studies show that Tachyonized Silica Disks installed over the circuit breakers of your home or office neutralize the negative effects of EMFs and, at the same time, improve biological functioning. These groundbreaking studies also strongly indicate that when your circuits are protected by Tachyonized Silica Disks, food prepared with electrical appliances have greater energy.
