As we previously stated, it is already shown in particle physics that any electric charge is an asymmetry in the violent energy exchange between the vacuum and the charge.
Every charge is therefore either a source or a sink.
Any dipole is automatically a source on one end and a sink on the other, freely extracting and gating excess energy from the vacuum. This is true for both an electric dipole and a magnetic dipole. To build a free energy EM source, we do not have to discover how to extract and gate excess energy from the vacuum. Every source we have ever built is already doing just that. We only have to discover how to cease using half the extracted energy of a dipolar source, to do work on the internal separation of charges that makes the dipole itself.
