So, here's some of my work on the subject, the results and a little science.
Stiffler was radiating water with electromagnetic energy produced by a SEC - a test tube of water with a small signal diode fully submerged. Stiffler was convinced that this was unknown science that was yet to be explained, and that something extraordinary was occurring because only hydrogen was seen to be evolving from one leg of the diode. Huh?
At the time I offered an explanation to what was happening and it did not go down too well. My explanation was aggressively opposed not only by Stiffler, but also by many of his devotees.
But Stiffler was making some rudimentary blunders in his assumptions, the most obvious being that only hydrogen was being produced. Of course you have to ask yourself how can you split the water molecule and be left only with hydrogen - of course you can't, but Stiffler refused point blank to discuss the point.
In actual fact, all that is happening is that the small signal diode is simply rectifying the EMR which then provides a tiny voltage drop across itself. This is enough to initiate standard Faraday electrolysis, hydrogen evolves at one leg of the diode, while oxygen evolves at the other… but the oxygen immediately reacts with the tin plating on the one diode leg, turns to SnO and slowly precipitates to the bottom of the test tube. Hence no oxygen is seen to be evolving as a gas, but it is still being produced. Faraday’s Laws of Electrolysis in action.
To satisfy myself that I was indeed thinking along the correct lines I did quite a lot of experimenting with this and found that I could achieve the same or better results than Stiffler with his SECs, with a simple Joule Thief or a car ignition coil generating EMR (at various frequencies).
I also realised that the diode body itself does not need to be submerged as Stiffler had done; just the legs are all that is required to be in the water. I also used LEDs instead of small signal diodes to great effect.
I've uploaded diagrams of my experiments:
