In the video I think you are talking about there is no treatment to the tubes at all.
There's a couple videos where I heated the tubes and created a carbon layer that was a few Mega ohms and the layering gave it a diode characteristic. I am
assuming that it's got to be this...
http://www.scielo.br/scielo.php?pid=S0103-50532002000400005&script=sci_arttextThe heat treatment created the CrO2 inner layer and FeO2 outer layer, but, the butane flame deposited a carbon layer (resistance) on top...the result was more charge retention (slower charge leakage into water) and, a diode characteristic.
Myself and another person (collaborating on skype) both found that you could run it wired up in only one way (The treated tube as - ). Otherwise the layer would be forced off the electrode by the +pressure wave.
When the water was made to conduct (electrolyte added), the cell was wired up correctly, and, 120vdc was applied, the 100w bulb in series with the cell would not light, meaning very little current was flowing. However, when the electrode polarity was reversed the light lit up and the layer was "ejected" from the now + treated tube.
I have never said it was what Stan was doing....nor that it was needed...I simply wanted to show that
certain layers
may be beneficial here.
I will say however that is most likely a factor in Stan's technology, because, it's going to happen no matter what!! (unless the electrode(s) are insulated)...As you see from the research any type of energetic/oxygen rich environment will cause the FeO2/CrO2 boundary interaction...this is very good, it's like the action of a lead-acid battery with lead + electrodes and Lead oxide - electrodes. It makes a one way energy storage take place (also like electrolytic capacitors).
