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. (Wikipedia:Bubble fusion)

Since "Sonoluminescence is the emission of short bursts of light from imploding bubbles in a liquid when excited by sound." (Wikipedia:Sonoluminescence) 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.

  • Sonofusion Just Now Starting to Go Mainstream - Considering the recent media fawning of the Purdue bench top fusion results, Leslie R. Pastor points out other sonofusion research as well as other energy alternatives that are being overlooked, similar to the AC v DC controversy of Edison's time. (PESN; July 14, 2005)

  • Russ George and Roger Stringham's Involvement in Sonofusion - Clarification about who played what role along the lines of prior art in this field of fusion by cavitation; spurred by a question posted by cold fusion expert, Steven B. Krivit. (PESN; July 25, 2005)
  • Bubble Fusion Researcher Faces Fraud Trial - In 2001, Rusi P. Taleyarkhan claimed in 2001 to have successfully produced a positive net energy bubble fusion reaction. The New York Times now reports that a congressional hearing is under way against Rusi P. Taleyarkhan, even though Purdue University has already cleared the scientist of any wrongdoing.

  • The new sound of fusion - State-of-the-art science is capable of tapping sources of infinite energy and has been since the 1950s. The problem is, it has so far proved impossible to control this process. The energy is released in titanically destructive bursts. (Business-Standard; Mar. 18, 2004)

How To

    Sonoluminescence - Demonstrating elusive energy transference of acoustic stimulation of a liquid to light. Reminiscent of Stubblefields strangely glowing cabin near his end of life. A proof and "how to", demonstrating another intriguing energy form light - extracted from otherwise simple energy source - water. (Techmind; May 2007)

Research

  • Explaining how collapsing bubbles can get so hot - A new paper published in the New Journal of Physics proposes a model explains much of the sonofusion heating process, including a possible route towards heating the interior of the bubble further, making the process more potentially practical. (ARS Technica; May 14, 2009)
  • Desktop fusion is back on the table - Can the popping of tiny bubbles trigger nuclear fusion, a potential source of almost unlimited energy? Purdue physicist claims to have definitive data. (Nature; Jan. 10, 2006) (See also EurekAlert'')
  • Purdue Findings Support Earlier Nuclear Fusion Experiments - Researchers at Purdue University have new evidence supporting earlier findings by other scientists who designed an inexpensive "tabletop" device that uses sound waves to produce nuclear fusion reactions. (Purdue University; July 12, 2005)
  • Bubble Fusion takes next hurdle - Haiko LIetz says the potential for cavitation to induce nuclear fusion lets physicists think in new directions of energy production. (ZPEnergy; July 18, 2005)
  • More Evidence for Tabletop Fusion - Slashdot post about Purdue University's statistically significant evidence that their tabletop fusion experiments were successful. Notes that it still doesn't surpass a break-even point. (Slashdot; July 17, 2005)
  • Bench Top Sonofusion at Purdue and Rensselaer Polytechnic Institute - IEEE reports apparatus that produces nuclear fusion inside tiny vapor bubbles may one day give us cheap, clean, and virtually limitless energy. (PESN; April 28, 2005)
  • Evidence Bubbles Over To Support Tabletop Nuclear Fusion Device (ScienceDaily; Mar. 3, 2004) - Inexpensive process generates nuclear reactions by creating tiny bubbles, which implode with tremendous force. New York Times and Physics News opine, "many scientists [see] uncomfortable resemblance to 'cold fusion' which has now been discredited." Actually "cold fusion" has been proven soundly. PES review pending in a few days. (Submitted by Marc Plotkin)
  • Temperature inside collapsing bubble 4x that of Sun - Using a technique employed by astronomers to determine stellar surface temperatures, chemists at the University of Illinois at Urbana-Champaign have measured the temperature inside a single, acoustically driven collapsing bubble. "We used to talk about the bubble forming a hot spot in an otherwise cold liquid. What we know now is that inside the bubble there is an even hotter spot, and outside of that core we are seeing emission from a plasma." (PhysOrg; Mar 2, 2005)
