Sergh thanks for the Russian patent link it was very helpful, there is more than way to split water below the 4.2 Kw m3 cu. RF is the way Zografos uses that way. I am suspecting that Ag ionic solution in water is added to water, as I am formulating the ppm of Ag in ppm is needed to make that effect . In the videos of P.Z. he drinks the water as it has to be safe for him to drink. As to metals P.Z. adds to the test tube is there for resonance as one needs a beat frequency as a base to create a oscillations to split water.  Not a standing wave but a "superposition" wave.. P.Z. spectrum display shows that the frequency is in the 250 to 350 GHZ. so it has to be a harmonic of the lower frequency which is indicated by the size of the wave guide .. as to prevent HHO from falling back to a lower energy level one has to maintain that oscillations as shown in the video where P.Z. shuts off the RF and the flame goes out.  I am certain that John Kanzius had the right method, however he was not at the right resonance , 13. Mhz is the industrial set aside frequency that is aviable to most sputtering systems and you may want to be else where say at 200. Mhz like the Coleman patent to generate alpha and beta...  I will post some clips like the method the Herman Anderson has dome spark oscillations.. See his clip as the end is priceless it's there PWM sparks from a motorized automotive distributor that can be controlled by varying speed of the frequency some what Bob Boyce did with the half wave failed six diode bank in his alternator.


Acca.  keep on as Zografos will save Greece from the robber banksters..

Where is Sergh ? This is for him.

Who has any idea what it is?

This work as transmitting antenna:

The dimensions are approximately the same as in the video from Petros Zografos.
To determine the size I used as sample the white cable that is present in the video. Very roughly.
Transmission lines 16 millimeters, "wings" 22 millimeters by 6 millimeters. The base material is the microwave Teflon 2,5 mm thick. 
Due to the large thickness of dielectric base the line width is increased.I tried to install this antenna near the flange of the waveguide or near the detector diode. The amplitude of the received signal increases significantly.I was planning to solder a Gunn diode in the center hole, but it overheated during soldering.It is a pity that a diode of this size was only one at these frequencies.  I have such diodes for higher frequencies. I will try later with it, it will be soldered with the Rose alloy.
I found interesting Greek article about experiments with underwater communication in the microwave range, from a city called Zografos  :

Here I am about the same. Why everyone wants to introduce microwave energy from the air. waveguide or coaxial. Inside the water, without leaving the water, what prevents to do this?

I tried. Don't work. The generator does not start, or works very poorly.

something I do not understand, in this case, what could be wifi under water.?

Has anyone looked at this?
