Directory of technologies and resources relating to sonofusion, also known as bubble fusion, which involves room temperature fusion using sound frequencies

: "Sonoluminescence arises from acoustic cavitation -- the formation, growth and implosion of small gas bubbles in a liquid blasted with sound waves above 18,000 cycles per second. The collapse of these bubbles generates intense local heating." (PhysOrg Mar. 2, 2005)

Overview

Bubble fusion, also known as sonofusion, is the non-technical name for a nuclear fusion reaction hypothesized to occur during sonoluminescence, an extreme form of acoustic cavitation. Officially, this reaction is termed acoustic inertial confinement fusion (AICF) since the inertia of the collapsing bubble wall confines the energy, causing an extreme rise in temperature. The high temperatures sonoluminescence can produce raises the possibility that it might be a means to achieve thermonuclear fusion. At temperatures hot enough, atoms can literally fuse and release even more energy than when they split in nuclear fission, now used in nuclear power plants and weapons. Furthermore, fusion is clean in that it does not produce long-lived nuclear waste. (There was an error working with the wiki: Code[3])

Since "Sonoluminescence is the emission of short bursts of light from imploding bubbles in a liquid when excited by sound." (There was an error working with the wiki: Code[4]) then the phenomenon ceases at a relatively low temperature ceiling when the fluid looses its grasp to the air particles, making them evaporated. This fact contributes to this notion of sonofusion if it happens it only occurs in that narrow range.
