The focus here seems to be on mixing
ultrasonic sound vibrations with a
standing voltage to perform the work,
but the story doesn't seem to end there.

Once liberated, the effect of vibration
still continues on the gases themselves.

Here is an example of what I mean:

Although Stanley used piezo elements
on the bottom of all of his tubes.

It may not have been only for the split,
but to condition the pairing afterwards.

The notch out of the outer pipe's top edge
like on a church's pipe organ's pipes to tune it
would raise the pitch to match the inners pipe's
naturally higher pitched resonance.

Thus making them a resonant cavity
where the gases are pairing off.

Please note that unlike the unstable gas pairs
from plain brute-force Faraday electrolysis
that seek to equalize with vengence,
and will explode when compressed.

The above gas can be stored, and the Hydrogen
doesn't leach through the storage container's walls.



Here is an explaination I bumped into.

I think the hydrogen oxygen bond at nano scale
is augmented by sodium in the transition between
water and the Ohmasa Gas formation.
The electrolyte bond with hydroxyl is broken
at the gas formation boundary and retained
by the gas molecules because of the
nano sized bubbles affinity and charge polarity
at the transition to a gas.
A mass spectrum of the Gas may produce evidence
of hydroxyl in the Gas molecules equally bonded
to hydrogen and oxygen.
A check of the Ph of the water in the exhaust
would give an elevated acid level if this were true.
The increased molecular size may account for
stable storage because the container will not permit
passage of this large a molecule.
