Text: T he Lawrence Livermore National Laboratory, University of Mississippi and University of California scientists are trying to determine how to use sonoluminescence - light created by passing sound waves through water - to trigger fusion. A Cray supercomputer determined that for about 10 ps, the temperature at the center of the exploding, light-emitting water bubbles peaks at between 100,000 and 1 million degrees at 100 million or more times normal atmospheric pressure. Scientists hope that by increasing the temperature and pressure just a little - by shaping the sound waves, for example - they can fuse deuterium. It will still be just a tiny reaction.
