We've shown that chemistry occurs within a collapsing bubble, and that it limits the energy available during cavitation

Sounds like some vocational myopia.
The cold fusion dudes were so focused on a physics-based solution that they forgot their chemistry.
Well, for the time being we still have advanced fission reactors to address our energy needs.

The cold fusion dudes were so focused on a physics-based solution that they forgot their chemistry.

And some people were so focussed on the knee-jerk nay-sayers that they forgot to look at what was actually going on in these reactions (since replicated in labs all around the world using the original and other types of apparatus).
