Hmmm let me see... 18,000V @ 1 Amp = 18kW electrical input power,
aluminimum wire being destroyed at a rate of 30mm per second...sounds
more like a TIG welder!
With 18kW you could make a reasonable electric vehicle and not have
to feed it water & aluminium, nor dispose of huge volumes of
aluminium oxide.

Yes, I think this is pulse current or mesured on 12V side.
A truly excellent reference (Hydrogen generator using water and aluminium as
feed stock).
But PLEASE put a brief reference to what such links are about so we can
decide whether to look at the, I would probably have missed this site if
others had not changed the subject line.
Some real possibilities using scrap aluminium.
A British torpedo ran in Aluminium & seawater.
Is there not a very fundamental relationship between the energy required to
separate the Hydrogen and Oxygen and the energy released when the two are
recombined?

There are some serious technical inconsistencies in that
article. A pair of automotive ignition coils will give 18kV
or more peak, and an amp or more peak, but the average power
is quite low. Low enough that I don't believe for a second
that it could ignite aluminum underwater! Not a chance. If
they drove both coils with inverters at the resonant
frequency of the output circuit, then it might work -- but
that's not what they're talking about.
The circuit shown is completely out of the question. The
text refers to a "conventional distributor and coil
arrangement", but the figure shows a highly
unorthodox "distributor" on the *primary side*. That's not
where it goes. Then they proceeded to put the secondaries
of the coils in parallel, and drive them 180 degrees out of
phase. They added a capacitor across the output, too --
just to eliminate the remote possibility that it might still
work, I guess.

The point is that the bulk of the H2O dissociation energy is provided by
the Al reacting with O, not by the electrical source. The latter only
provides a small part of the energy. And I don't think it's 18kW else the
water in the tank would superheat in 15 minutes. He uses two standard
ignition coils acc. drawings so it would be more like 200-300W input. I
think that the Al oxidation also contributes heat to the device so
relatively little electrical power is needed.
