'Gene said "cavitation", not "bubbles."  Sonoluminesence is called that 
for a
reason. The bubbles glow. You can see them withthe naked eye.

When you boil water, does it glow? No (at least mine doesn't.)

Why should I bother to boil deuterated acetone? I have no reason to 
believe it
will glow. I would start with ordinary acetone if I were to bother. The 
experimenters
have in fact observed SBSL in ordinary acetone: they use it as a control 
for the
experiments with deuterated acetone.

Please do not confuse SBSL fusion with "cold fusion." "Cold fusion" was and
experimental observation without a theory, with ever more exotic 
theories propounded
to explain it.

By contrast SBSL fusion derives directly from a very simple theory. The 
theory is
that the bubble glows because of adiabatic compression. This was 
observed prior to
any fusion was even being looked for. scientists did the math and 
decided that the
temperatures couild be raised into the fusion range if certain 
conditions cold be met,
and they set out ot meet them. In particular, the amount of energy in 
the expanded
bubble can be raised by increasing its size, so they looked for a liquid 
in which the
bubble would be bigger, and they found one. Then they looked for 
neutrons and found them.
This is a clessical example of the scientific method and is in marked 
contrast with the
cargo-cult "science" that surrounded "cold fusoin."
