I found these two simple keys to explain how “free” energy is possible. In the q & a by Foster Gamble under the subject of New Energy Technologies at the thrivemovement.com website (reformatted a bit, red bolding mine), the question is “What is Free Energy?” This is part of his answer:
But isn’t a perpetual motion machine impossible?
Of course no machine runs forever, because it is made of matter and all matter wears down.
The key is that it is the source of power that is virtually endless.
But isn’t it true that nothing can violate the 2nd law of thermodynamics which says that in a closed system the organization of energy naturally runs down, so you can’t get more energy out of a system than it takes to run it.
2nd Law of Thermodynamics
“Over time, differences in temperature, pressure, and chemical potential equilibrate [all balance out] in an isolated physical system. From the state of thermodynamic equilibrium, the law deduced the principle of the increase of entropy … The second law declares the impossibility of machines that generate usable energy from the abundant internal energy of nature by processes called perpetual motion of the second kind.” – Wikipedia
The second key is that a torus is not a closed or isolated system. It is open to the rest of the universe, as are galaxies, solar systems and the atoms that provide the electricity in our very own bodies.
None of these are plugged into a wall socket. They all run off the infinite torque of the universe that is turning every system in existence. So what if there were devices that could tap that?
Most so-called “New Energy” devices, in my experience, either tap the innate energy of (toroidal) magnetic fields or they access the virtually unrecognized “longitudinal wave” at the center of an electro-magnetic vortex rather than the more commonly known “transverse” wave that is coiling around it. Others mimic cosmic vortices with copper coils that create toroidal fields. Rotating these fields at certain octave frequencies seems to tap into the ambient energy of the space around the coils. Harmonic resonance rather than combustion unlocks the power.
