INTRODUCTIONINTRODUCTION

Sonofusion Research team from various Sonofusion Research team from various organizations have joined forces to create organizations have joined forces to create acoustic fusion technology energy consortium acoustic fusion technology energy consortium (AFTEC) to promote the development of (AFTEC) to promote the development of sonofusion.sonofusion.

It was derived from a related phenomenon, It was derived from a related phenomenon, sonoluminescence.sonoluminescence.

Sonofusion involves tiny bubbles imploded by Sonofusion involves tiny bubbles imploded by sound waves can make hydrogen nuclei fuse-and sound waves can make hydrogen nuclei fuse-and may one day become a revolutionary new energy may one day become a revolutionary new energy source.source.

SONOLUMINESCENCESONOLUMINESCENCE

When a gas bubble in liquid is excited by When a gas bubble in liquid is excited by ultrasonic acoustic waves, it can emit short ultrasonic acoustic waves, it can emit short flashes of light suggestive of extreme flashes of light suggestive of extreme temperatures inside the bubble.temperatures inside the bubble.

These flashes of light, known as These flashes of light, known as ‘sonoluminescence’, occur as the bubble ‘sonoluminescence’, occur as the bubble implodes, or cavitates.implodes, or cavitates.
