New evidence about a tabletop device that uses sound waves to produce nuclear fusion suggests that previous experiments were no fluke, and that the process might eventually provide safer and much cheaper nuclear power.

Researchers from Purdue University in West Lafayette, Indiana are reporting new evidence showing that the process, called “bubble fusion,” generates nuclear reactions by creating tiny bubbles that implode with tremendous force.

“What we are doing, in effect, is producing nuclear emissions in a simple desktop apparatus,” says Purdue researcher Rusi Taleyarkhan. “That really is the magnitude of the discovery—the ability to use simple mechanical force for the first time in history to initiate conditions comparable to the interior of stars.”
