The present invention relates high power AC steering flux cancelling inductors and processes of making and using same. When properly configured and wired such inductors, separate the AC component and DC component of a high power current thus allowing the smaller AC fraction of the overall current to be carried by much smaller cross-sectional litz wires. Such high power AC steering flux cancelling inductors are more efficient at avoiding core saturation compared to standard inductors, yet they are less expensive without the need for large cross-sectional litz AC carrying wires. In addition to the aforementioned benefits, such high power AC steering flux cancelling inductor permits the levels of AC and DC current to be efficiently monitored as such currents are separated.

A novel transformer circuit employing multi-axis windings around a large magnetic billet receives and amplifies the energy from a flux of energetic waves emanating from the sun and other celestial bodies and entities throughout the environment. A clean source of solar energy can be harvested with an energy density that is at least 50 times greater than photon-based collectors.
