This prohibits the formation of normal current. Instead, current finds no other outlet than to reverse itself and exit the same way it came in. And since it is reversed current, relative to voltage, then it increases voltage differences rather than equalizing them, and is the definition for the generation of electric power under passive sign convention. This has the consequence of converting passive components, such as: coils of wire, into active components (which generate power rather than consume them to offset the miniscule power entering this type of circuit) and replaces any significant prime mover since the activation of passive coils becomes its own significant prime mover. The catalysis which arises from the environmental background voltage remains significant, but not because it delivers power, but because it is a dependable resource to rely upon since “perpetual motion machines who do not require any input of power” is not a fantasy so much as it is a misrepresentation of the reality of free energy augmentation.       The generation of free energy is a multistep procedure involving the acquisition of nanowatts or picowatts of power from our environment to act as a stimulant to catalyze over-reactance of pairs of coils working in conjunction with pairs of capacitors, followed by the augmentation of this reactant voltage via an open transmission line archetype, followed by a self-shorted transmission line archetype (made manifest as a self-shorted coil) to offer a pathway for current to form. This current will remain in opposition to its voltage and may not require its shift of phase (by 180°) to correct for this power factor since it is already usefully sending power back to its source!
