Not entirely, Gene. Common consumer AC/DC power supplies are
notoriously unfiltered, leaving significant degrees of alternating
signal on a DC carrier voltage. 

There have been claims that the electrodes used by Pons and Fleishmann
were properly baked to drive out common hydrogen from gaps in the
crystal structure, allowing deuterium to take it's place and fuse more
readily. This baking process was not used by other researchers. I can't
say one way or the other.

Saying the sonofusion isn't 'cold' because it achieves 100k K temps at
the point of collapse is a bit disengenuous. Even CF proponents claim
high temps at the micro level where allegedly fusion occurs. The 'cold'
moniker applies to whether the entire reactor operates at temperatures
above sea level boiling points and pressures or not.

On the contrary, heating water, or any fluid, to the edge of the
boiling point creates a phenomenon where the hot surface creates
bubbles in a boundary layer at the boiling point. As soon as the
bubbles rise out of the boundary layer, they are cooled and collapse.
Whether they collapse fast enough for fusion is a different question
entirely, and I don't think anyone has done an experiment with trying
to boil deuterated acetylene yet.
