Researchers report bubble fusion results replicated ~ Cold fusion no longer confusion

BOFFINS FROM the Rensselaer Polytechnic Institute (RPI), Purdue University, Oak Ridge National Laboratory (ORNL), and the Russian Academy of Science (RAS) have managed to replicate controversial cold fusion experiments.

A March 2002 an article in Science (Vol. 295, March 2002), indicated that boffins had managed to use bubble fusion successfully, but this data was questioned because it was made with imprecise instrumentation.

Now Physical Review E is publishing an article by the team of researchers stating that it has replicated and extended previous experimental results and this time has used the right instruments. Cold fusion is a bit of a holy grail in the science world because if it could be made to work, it could produce a lot of energy without having to have a large amount of energy to start it.

Scientists have managed to do it in the past, but it always required more energy to be put into it than could be taken out, which is defeating the point a bit. A press release going into the details can be found here. µ

Freepers must have argued with me a dozen times after I said that.

That's because it's an extraordinary claim. The very fact of their objections supports your point. ;^)

Actually, the correct citation is:

http://scitation.aip.org/vsearch/servlet/VerityServlet?KEY=ALL&smode=strresults&maxdisp=25&possible1=Taleyarkhan%2C+R.+P.&possible1zone=author&OUTLOG=NO&aqs=true&key=DISPLAY&docID=2&page=0&chapter=0&aqs=true

Your citation is for the erratum, which was published in 2005. As I suspected, the original paper was published March 22, 2004.

I haven't published in Phys. Rev. for several years, but it was about 10 months at that time.

I agree. If this is for real, can it be contained at levels high enough to be of any commercial use?

Will this be named the "Mad Baggins" project?

Something is not right hear.

BTW, it's here.

A new discovery takes years of reworking, negotiating for contract and rights on the invention, getting investors to help fund the early, expensive costs of starting up any kind of marketable devices.

RCA wasn't built in a day.

Apparently, there will also be a consortium:



CORRECTING and REPLACING Consortium Formed to Study Acoustic Fusion; Could be Alternative to Oil, Gas, Coal and Nuclear Power

     CORRECTION...by The Acoustic Fusion Technology Energy Consortium

GRASS VALLEY, Calif.--(BUSINESS WIRE)--Jan. 12, 2005--Sixth graph, first sentence should read xxx Dr. Rusi Taleyarkhan, The Ardent Bement Jr. Professor of Nuclear Engineering, Purdue University, and part-time Distinguished staff at a National Laboratory (sted xxx Dr. Rusi Taleyarkhan, The Ardent Bement Jr. Professor of Nuclear Engineering, Purdue University, and part-time Distinguished staff, Oak Ridge National Laboratory).

The corrected release reads:

CONSORTIUM FORMED TO STUDY ACOUSTIC FUSION; COULD BE ALTERNATIVE TO OIL, GAS, COAL AND NUCLEAR POWER

The Acoustic Fusion Technology Energy Consortium (AFTEC) has been formed by leading academic and commercial institutions to research and develop acoustic inertial confinement fusion (AICF) and its related science, technologies, and equipment. AFTEC's five founders are (alphabetically): Boston University; Impulse Devices, Inc.; Purdue University; University of Mississippi; and University of Washington Center for Industrial and Medical Ultrasound.

Dr. Wylene Dunbar, Director of AFTEC, today announced the group saying, "Acoustic fusion has an excellent chance of becoming the alternative to oil, gas, coal and nuclear energy for the world's electricity -- if it is funded appropriately."

"If AICF delivers on its potential, the impact would be enormous. Fusion could produce electricity with a process that yields virtually no pollution--just ordinary helium and heat," Dr. Dunbar observed. "With acoustic fusion, the fuel is essentially water, and the cost to build and operate a plant would be a fraction of other alternative energy facilities. Furthermore, the timetable for acoustic fusion is arguably far shorter than all other paths to fusion."

In AICF, sound waves bombard a liquid such as heavy water, to create tiny void "bubbles" or "cavities" of deuterium a/k/a heavy hydrogen. This produces very high temperatures and densities that, when high enough, fuse the heavy hydrogen into helium. That fusion releases enormous heat that could be used to create steam and drive a turbine to produce electricity.

An emerging field, acoustic inertial confinement fusion can already lay claim to significant progress: A multi-institution team led by Dr. Rusi Taleyarkhan has twice documented fusion reactions taking place in an AICF reactor, with the results of those seminal experiments published in two prestigious, peer-reviewed journals, Science 295, 1868 (2002) and Physical Review E 69, 036109 (2004), and receiving publicity worldwide. Under the direction of its President, Ross Tessien, Impulse Devices has recently made available the first commercial research reactor for AICF.

Scientists leading AFTEC's research are preeminent in the field: Dr. R. Glynn Holt, Associate Professor, Department of Aerospace/Mechanical Engineering, Boston University; Dr. D. Felipe Gaitan, (discoverer of single-bubble sonoluminescence, a phenomenon closely related to acoustic fusion research), Chief Scientific Officer, Impulse Devices, Inc.; Dr. Rusi Taleyarkhan, The Ardent Bement Jr. Professor of Nuclear Engineering, Purdue University, and part-time Distinguished staff at a National Laboratory; Dr. Henry Bass, Director of the National Center for Physical Acoustics, University of Mississippi, and F.A.P. Barnard Distinguished Professor of Physics & Astronomy; and Dr. Lawrence A. Crum (leading researcher in the field of high intensity focused ultrasound and past president of The Acoustical Society of America) Professor of Bioengineering and Electrical Engineering and Director, Center for Industrial and Medical Ultrasound, Applied Physics Laboratory, University of Washington.

Members of AFTEC will work as a team to investigate acoustic fusion, Dr. Dunbar noted, and will consult with National Laboratory scientists for independent verification of positive results, as they are achieved.

"All of the scientists involved with this research appreciate that acoustic fusion is a relatively new field and one that has, so far, received little funding support," Dr. Dunbar stated. "Nevertheless, given AICF's potential for creating a limitless, nonpolluting source of sustainable energy, as well as myriad other applications, they also agree that the investigation of acoustic fusion is critically important and deserving of high priority."

Dr. Dunbar received her Ph.D. in Philosophy from Vanderbilt University and her J.D. from the University of Mississippi.

Goodbye dependence on Middle East oil. Or any oil. Since they'll have nothing else to sell the world...I don't count their rugs...Islamofascists will be upset. No more income. No more oil cartel. Saudi Arabia had better start reading the tea leaves.

One important question is, can a sustained reaction dissipate heat sufficiently to allow it to be contained anywhere?

From what I gather, the fusion occurs when tiny bubbles in the liquid collapse under the influence of ultrasonic waves. So the 10MegK temps occur in very tiny regions within the liquid, and the resulting heat makes the liquid warmer.

The big trick will be: can they make it happen with the liquid at an operating temperature sufficient to generate steam (to power a turbine), and with the energy input being significantly less than the energy output

Would it not be more correct to say that its a holy grail becuase of the efficency with which it releases energy? It really does not produce more energy than went into making up the atoms being fused.

very accurate and insightful observation. I get the image of the comedian with the puppet waving his hand over his head and going "vrooom."

It's the little things that make the difference between accurate observations of reality and really WRONG portrayals based on imprecise descriptions.

It really does matter. Thank you.
