How big and how heavy was the aparatus in which they created fusion?

Secondly, how much heat was generated by the apparatus?

My understanding of these things is that it is a metal ball about a foot in diameter with a hollow center were the sound pressure is focused.

It is not cold fusion, but rather hot fusion on a incredibly small scale.

They produced no heat, but did produce neutrons which indicates that fusion was occurring.

They have not been able to produce more energy than they put in which is, of course, the proof of the pudding.
