Tabletop Nuclear Fusion?

Experiment uses sound waves to generate super-high temperatures.

WASHINGTON - In a tabletop experiment, researchers created a reaction like nuclear fusion — the energy source of the sun.

Using a device described as the size of three stacked coffee cups, they zapped tiny dissolved bubbles with sound waves, triggering a flash of light and super-high temperatures.

Researchers at Oak Ridge National Laboratory and Rensselaer Polytechnic Institute say the phenomenon was like nuclear fusion in a bottle, but they are uncertain if it could be used as a source of energy.
