Yes, I think this is pulse current or mesured on 12V side.
A truly excellent reference (Hydrogen generator using water and aluminium as

others had not changed the subject line.
Some real possibilities using scrap aluminium.
A British torpedo ran in Aluminium & seawater.
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.
