G'day all,

For some information on sonoluminescence have a look at http://keelytech.com/sonoluminescence.html

Hope you find it interesting.

@ Haliburton:

Wow, that was a very detailed study on those shrimp.  Amazing little things.  I think your idea of a mechanical disk with holes to generate high speed pulses is very possible.  We once made a polished quartz "Chopper" wheel designed to break up a laser beam when it spun in its path for generating higher frequencies of light.  We made this for Bell Labs and, of course, they didn't tell us how or why they were using it.  If it works with light, why not water as you suggested?

One thing the video did not mention about the shrimp.  I find it difficult to believe that the piston on the claw and the pocket match with so much precision that this alone creates the implosion bubble.  After reading what Hans posted about how they have to introduce a small air bubble into the sealed bulb and manipulate it to the center before turning on the sound I got to thinking.  Nature always finds a way.  What if the shrimps "farts"  (for lack of a better term) a small amount of gas/air into the pocket to "charge" the claw just prior to slamming it closed?  I know the video did not mention this but this bubble could be almost microscopic and near undetectable but still be compressed to below the vapor pressure of the surrounding water causing the implosion.  Just a thought.  This would allow for a lot less precision fitting of the two parts of the claw and make more sense to me. I am just guessing, obviously, I am not a shrimp expert, although, they are good with a little cocktail sauce.

The article , that you cant remember the source...
comes from here:

Sparks    WOW that is allot of info in a few paragraphs Thanks

Thanks for the links, that Articles Extra is an awsome website.

    Ultrasonic tanks are designed to produce sonic waves that get out there into the field.  You want the cavitation to happen at the interface of the metals to be cleaned.  The metals absorb the sonic waves just like an atom will absorb a photon or emwave.  The metal then emits it's own wave which will result in cavitation at the metal to solution interface.  This is totally a result of the mechanical resonation of the metal matched to the frequency of the pressure waves.  The cavitation is so disruptive that it will etch the metal if a standing wave is created.  The frequency of the transponders are swept to avoid standing waves in the solution so as not to destroy the metal.  This is optimized cavitation differs from the cavitation that is the product of decreased pressure of a solution saturated with a dissolved gas as you would see on the output of a prop or in a hydraulic solution.  The solution using hydrosonic cleaning is degassed before operation of the tank for efficient transfer of the pressure waves from the transponder to the metal interface. 
     The cavitation of the liquid from the pressure wave hetrodyne results in a vacuum bubble not an expanding gas bubble.  There is no surface tension in a vacuum bubble and chemical reactions on the interface of the bubble will proceed as they would in outer space.  Water will boil rapidly at this reduced pressure and concentrate heat energy from the solution in the region of the vacuum bubble.  Upon collapse of the bubble this heat gain is being concentrated in an ever condensing field and the temperature increases at an astounding rate.  Plasma formation water fracturing and neuclear disintegration are all possible results of temperature rises like this. 
    The energy gains of cavitation boilers may be just the result of lowering the vapor pressure of the fluid so that water boils at a very low temperature in the machine allowing for heat transfer from the ambient field to flow into the system.
This is very simple physics and is used in reduced pressure distillation processes.
Either way mainipulation of pressure to lower vaporization temperatures is the way to go.

So i guess you are talking exactly about this: http://www.overunity.com/index.php?topic=6208.0
... I would be very happy to see some comments inhere... I belive that this is the most efficient way to obtain OU, what do you guys think?

...and don't tell me that the inventor is the only person on this freakin planet that did this...

I would also like to share a good video lecture that i came across - its about radionics and vibrational theory (John Worrell Keely's work) http://www.youtube.com/watch?v=TMEpCpzahFY&feature=PlayList&p=A426FDF5BA3CD7FD&index=0

Hope it opens some minds

Yeah that's great.
And had we been talking about induction heaters, it would have been on topic too.
But the thread is about cavitation, not induction.

Just to throw my 2 cents in:
- I don't see what is any more remarkable about the evolution of a shrimp which uses the
sonically induced cavitation of its naturally surrounding medium to produce a compact
shockwave that in some cases is strong enough to actually produce a minuscule plasma
flash, than there is about a bird which has evolved to use aerodynamics and currents in
its naturally surounding medium to give its body lift and speed. But then again, there's
many people who seem to have trouble understanding how evolution can shape the
various remarkably complicated mechanisms that we like to call organisms.

- Am I the only one who smells something fishy when people start talking about
Thrapp and his "Amish scientists"? Come on now. Amish scientists? That's almost
like vegetarian butchers or Jews eating bacon.

- Cavitationnally induced fusion is an interesting concept, and if heavy water were
used instead of normal water the plasma inside the compression bubbles might
even be used to fuse deuterium (and/or tritium) into helium. Experiments along that
road have been done (are still being done?).
Problem is, how would we get the energy out? A possible way would be to "simply"
have the miniature fusion reaction dump its energy into the surrounding water as heat
(or mostly heat), then use the hot water to run a turbine or generator.
And that is an idea not much unlike the Chain Reaction movie shows.

So what would we need to do this?
Well, a sonoluminescence setup, so that's what, a quartz tube with pure water in it,
and a speaker arrangement with a freq gen so the right frequency can be pumped
into the tube, and then of course input and output flow valves with a connection to
the generator or heat exchanger.
Then we need a generator that can run off the hot water.
And we need a supply of water to pump around, and preferably heavy water.
Where do we get heavy water?

Anyway, get all that set up water and air tight (you don't want to accidentally
inhale heavy water or tritium vapour) and get the sonoluminescence going,
and with some luck you can actually fuse enough of the stuff to produce
excess heat => energy.
