HHO Generation using High Frequency electromagnetic waves on water

explain to me from which sources the energy of compressed gas in electrolyzers is taken under pressure. The efficiency of a good electrolyzer is close to one hundred percent. And under pressure, it even rises, as we know. And the energy enclosed in Brown's compressed gas is taken as if from nowhere.

kolbacict, " is close to one hundred percent. ...". https://en.m.wikipedia.org/wiki/Electrolysis_of_water
Could you give us a reference  to your "good electrolyzer"- producer  ?
Or are for you 80-90% ~ close to 100%. ?

"If the pressure over the electrolysis is increased then more current passes for the same applied voltage. However, the output of gas per coulomb and the heating effect are both decreased. This is due to the increased solubility of the gases and smaller bubbles  both reducing the cell resistance and increasing recombination reactions" http://www1.lsbu.ac.uk/water/electrolysis.html 
The source of energy is the power supply.

High-pressure electrolysis is the electrolysis of water with a compressed hydrogen output around 12–20 MPa (120–200 Bar, 1740–2900 psi).[12] By pressurising the hydrogen in the electrolyser, the need for an external hydrogen compressor is eliminated; the average energy consumption for internal compression is around 3%.

Well, I'm wrong. Let 80-90%
But it was meant that the overvoltage (electrode potential) with increasing pressure to 10-20 bar
decreases. Electricity consumption decreases accordingly. According to my information.
And your wiki says:

the average energy consumption for internal compression is around 3%

I do not understand. Could it be at 200 bar when there is already an increase in consumption?

Well, maybe you are right. According to my information, with a moderate increase in pressure, consumption in kW / h at least does not increase.
interesting information. thanks.
