Ponderations on Cavitation (Updated with impressive results from a paper of 2018)

    "Formation of chemical elements under superdeep penetration of lead microparticles in ferrous target"

    These “ballistic” transmutations have been found more than once, and the 1000 m/s threshold speed seems significative. Other works have observed dramatic transmutations with projectiles made of bismuth, transmuted into Pt and B.


    Interesting experiments could be done with bismuth targets and the shockwave generators to see if one can produce a “Pt rich ore” from the targets.

    I have suspicion that the increase in reports of transmutation is a direct result of more people getting hands on cheaper analyzing equipment and subsequent abuse of it. Now BG is going to propose to treat radioactive waste by making it disappear.

    You are entitled to your opinion.

    Anyway, when evidence of a phenomena that is coherent within and between a range of conditions begins to pile up, it might be just time to review your starting assumptions that something is impossible.

  • Looking for an academic lab to do these experiments with deuterated ionic liquids and biggest magnets. There is vacuum into cavitation bubbles in ionic liquids, so the speed at the end of the collapse will be around 100km/s, perhaps higher. It is probably possible to get ignition. It will be cool for an engine for the Starship of Mr. Musk. (With a regolith tank over the engine, of course, in order to protect the crew.

    Really interesting setup fabrice DAVID , Are you looking for energetic anomalies, specifically? or your experiments are of a more broad nature of just observing the phenomena and see where it leads?


    I often get obsessed with the elemental anomalies as they are (somewhat) "easier" to see, but as bjhuang , recently, and others before, have shown, excess heat is often the primary observable outcome in this kind of cavitating conditions. The trick is how to measure it in a way that no one will question the results.

    If we ignore the disappearing lead.. could this be related to x-rays from peeling sticky tape?


    https://www.nature.com/news/20…20fingers%20(see%20videos).


    "The sticky-tape X-ray machine is also baffling others in the field. "You wouldn't have thought that so much of the mechanical energy would come out as X-rays,"

    If you read the paper you will see that it is directly mentioned and referenced, while found to be insufficient as an explanation, by far.


    Mind you, "ignoring the dissapearing lead", specially when the methodology employed warrants that there's no other explanation than saying that 75% of the material affected by the repeating shockwave indeed dissapeared, would be quite an odd thing to do.


    That kind of thinking reminds me of the the old metaphor of the scientists looking for the keys where there's light while knowing the keys aren't there, but insisting on looking there, just because there is light in that place.

    I also wondered if it would be possible to correlate the x-rays with the appearance of a hole by trying to shine light through the lead sheet. eg hole appears allowing light through to trigger a sensor?

    If you have read anything about X ray emulsion altering emissions within the context of LENR, you would know that the phenomena is triggered without any need of macroscopic correlated observation, and I would say that the X ray emissions detected here also happened without need for the hole to be produced.

  • In a classic “Taleyarkan-style" cavitation experiment, the bubbles of deuterated liquid (water or acetone) contain vapor.



    As the bubble collapses, this vapor compresses adiabatically, and it heats up and radiates. A lot of energy is therefore lost.



    In addition, when the high temperature vapor becomes supercritical, the molecules touch each other, and the compressibility drops dramatically, causing the shock wave to rebound (Much like in a supernova when the outer layers hit the surface of the the neutron star, to take an astrophysical analogy that I like.) So we still lose a lot of energy. But spectroscopic measurements show that the heart of the bubbles is heated to at least 10,000 degrees Celsius.







  • Only a small amount of energy is concentrated in the center of what was once an imploding bubble.



    In an ionic liquid bubble, on the contrary, the vapor pressure is very low, or even zero. During the implosion, the speed of matter increases, (as in a shaped charge) and the molecules of liquid meet in the center with a speed of the order of a hundred km per second. And this energy is transformed into heat. If we use a deuterated ionic liquid, maybe it would be possible to get a break-even? (and maybe an ignition)



    One could imagine a nozzle at the rear of a vessel ejecting a jet of deuterated ionic liquid through a well-designed nozzle. The energy of protons, helions and newts would be absorbed by the liquid, which would be heated to a high temperature and relaxed by a divergent. We should get a considerable thrust.



    This classical ionic liquid could be easily deuterated:

  • With a magnetic field, the idea is to obtain small plasmoids which will confine the matter for a while, which will perhaps increase the reaction efficiency.



    Indeed, salt water or better, an ionic liquid which moves in a magnetic field gives rise to the induction of a strong electric current by MHD effect. This current will generate a magnetic field which will confine the current. This would result in extremely hot small tori, with fusion reactions inside.
