Cavitation. The key to overunity?

[elektromann]

G'day all,

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

Hope you find it interesting.

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

    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.
