you can see the following
Then with the rapid increase the electrolyte loss was too great to sustain as it poured into the bubbler
So it is not self sustaining.
I have worked on a project called flow electrolysis. This is used to normally create an other product during the flow of by a plate capacitor.
energy input = energy output, so no gain.
But there is an interesting effect when you use instead DC AC.
So the water is splitted in a resonance case and build more HHO as the normal splitting from water to H2 and O2.
have a look to
https://en.wikipedia.org/wiki/Stanley_M ... _fuel_cell
HHO is not the same as H2 O2, the energy input to create HHO is less than the energy input so separate water to H2 and O2.
A flame produced with HHO will reach about 6000 degrees, so it is much hotter than the burning flame of gasoline.
The efficiency of an HHO flame is thus much higher than with a gasoline combustion.
The interesting part is behind the explosion of HHO.
After the explosion there is following an implosion.
The implosion will reduce the volume by the factor 1000.
This is better than in any known high tech motor where whe have a compression 1:10 or 1:18, here we have 1000:1
A reverse process.
A dangerous process for the material if not handled properly.
