The steam resonator was part of his last patents that expired in 2012.
It's incredibly simple...it's two identical ungrounded transformers with their primaries wired in series. The secondaries are attached to stainless steel plates, and the plates are overlapped in such a way to block their current paths, and still impinge an oscillating force on the water molecule. Basically the closest opposite polarity electrode is from the other transformer, so no direct ionic connection can be made across either transformer's secondary, so the load is only the primary current draw.
If I remember correctly it's like this....LXLS=Left transformer left secondary wire, RXLS=Right transformer left secondary, LXRS=Left transformer right secondary, RXRS=Right transformer right secondary
First 1/2 cycle

Edit: had the polarities mixed up, fixed
(The like charges in the middle repel the ions trying to go to the opposite side of their respective circuit...as the electrode plates are close together...say, no more than a centimeter apart...more like 5mm I recall from the disclosure photos)
