Researchers at Purdue University have new evidence that supports earlier findings by scientists who designed an inexpensive "tabletop" device that uses sound waves to produce nuclear fusion reactions. A key component of the Purdue experiment was a glass test chamber filled with deuterated acetone, a liquid which contains heavy hydrogen. The researchers exposed the test chamber to neutrons and then bombarded the liquid with a specific frequency, causing cavities to form into tiny bubbles. These bubbles then expanded to a much larger size before imploding with enough force to cause thermonuclear fusion reactions.
