looking at how much we have to pump into the system is telling a different story.
To isolate all calculation and measurement errors the signal and power source need to be independent and based on DC. This will allow exactly how to calculate the power required to drive the load. If we then generate enough power we simply need to feed that back to the source and produce a self sustaining power system. You find the video under Movies and NG Coil Design.
