sonofusion is back

Sonofusion, despite some high profile negative results before, Purdue findings support earlier nuclear fusion experiments.

Now the idea is that you get a beaker of liquid acetone where the hydrogen has been replaced by heavy hydrogen, then by playing a sound through it bubbles are created. As these bubbles collapse the gas inside gets very hot and dense, hot enough for the deuterium to fuse. This technique has the advantage that, like in a Fusor, all of the fusion fuel is moving towards the same point and will end up hitting in primarily head on collisions.

The weird thing is that they claim that this reaction is Deuterium-Deuterium, and yet needs to have lots of high energy neutrons pumped through it to make it work. Small problem, in no other type of reactor does Deuterium-Deuterium need lots of high energy neutrons, this is a unique requirement of this set up. Then when you realise that they claim that they are getting fusion because they are detecting neutrons being emitted things start to look dodgy. I'm sceptical.
