A Real Star in a Jar Sonoluminescence work by collapsing a small bubble in a liquid using sound waves. The when collapsed, the bubble reaches temperatures as hot as the surface of the sun My question is, if we made a bubble big enough(like the size of a small car) in the right liquid, and collapse it using incredibly powerful sound waves, can we create a fusion reactor with it? The cooling issue, wich plagues most fusion reactors won't be real issue since the whole thing is in a liquid. What do you guys think?
