It is not more a cold fusion than the inertial confinement fusion people are
doing. If it's for real; interesting if you could scale up the setup with 
high-precision spherical assembly collapse, something not invoving acres of
high-power lasers.

That's because it (if it at all happens) involveds hot 
(claimed ~100 MK), dense deuterium plasma. Remember, there's a reason why it
glows.

You have no basis for this assumption. Absolutely none.

If it's rectified, there are no higher harmonics. It's not a switching power
supply (I think they did use a switching power supply, but I don't remember
the setup).

No. If you want cavitation, you need piezo or magnetostriction actuators, and
maybe even an acoustic lens.

Palladium cathodes get loaded with up to 1000x their volume in hydrogen when
electrolyzed. This loading increases the lattice volume and introduces
fractures, though which atmospheric oxygen can enter. Palladium catalyzes
oxygen/hydrogen reactions.

The whole process is nonlinear, but now and then you'll get massive
exothermic reactions supposedly from nowhere, if you're a lousy experimenter.
