The energy is life force energy, chi, prana and it is a subtle energy (which means that there are no current scientific instruments to read it. -the human body is very sensitive to it, so people notice it and we can use kinesiology or muscle-testing to measure it). It is a similar energy to what runs through our meridians, which is recognized by Chinese medicine. It is all around us all the time. Nikola Tesla and others recognized it as the “ether” and created machines to harvest the energy. The FLFE machine is built on the same principles and pulls in great amounts of the available energy and focuses it to create the FLFE wave.
