I always wondered why this did not receive more attention in the physic field. I remember reading that it could be produce with just water ultrasonic device to cause cavitation of bubble to get this effect.

It generates very fast flash of light,

Abnormally high heat.

Those are not easy thing thing to do with low power devices.

I'm guessing it doesn't scale up, but I don't think billions were spend to try (looking at you tokamak)

You mean specifically in the context of fusion power? Well, fusion is primary concerned with efficiency, and this isn't much efficient and has no avenue for improving.

It can probably scale up on the sense that you get more light emitted, and more high-energy regions. That is just not enough.

It probably will be very useful to replicate that heat-concentration effect on other contexts. But my guess is that the experiment has not gathered much attention yet because nobody invented those contexts. So there are only the purest of the theoretic interest.

Maybe it cannot act as a direct catalyst for fusion but it could potentially act as a catalyst for another potential catalyst for fusion, such as a pellet of fissionable material.

Just re-read this and realized that I'm using the term catalyst in a way that would make a chemist eyes weep. These would be used up in the reaction so it's not a true catalyst but the term has been kind of co-opted to mean anything that can speed up the reaction of something.

Why?

I mean, we have all sorts of ways to generate heat and light already. So what special quality do you perceive sonoluminescence potentially having at a large scale?
