                                  CAVITATION

There are four basic types of cavitation. Fundamentally cavitation results
from a drop in pressure on a liquid creates pockets or bubbles in the liquid -
an increase in pressure causes these bubbles to collapse resulting in a
tremendous "local" force which can cause damage to metals, emulsification, de-
gasification, sonoluminescence and many other strange and wonderous phenomena.

Who was John W. Keely?

John Keely was an independent researcher specializing in the properties of sound during the mid to late 1800's.

What did Keely discover?

He was purported to have discovered techniques based on incredibly sensitive vibratory mechanisms which would allow the use of the Aether for practical purposes.

What devices did he build?

1) a machine to split the water molecule for the instantaneous release of tremendous pressures

ok
wikipedia likes to call sonofusion "bubble fusion" too (see end of message)
acoustic cavitation they want to call sonic cavitation.

so according to this Sonofusion is a common name for nuclear fusion, occurring during sonoluminescence, which is an extreme form of acoustic cavitation. acoustic cavitation occurs when ultrasound-waves are passed through a liquid, which causes the formation of bubbles, which is known as cavitation.
because a sound-wave periodically compresses/decompresses (NOTE! inhale-exhale) a liquid, cavitation can be produced in the low-pressure part of the cycle, when the sound intensity is enough.

WikiPedia when talking about cavitation, mentions impellers, but does in no way explain whether there is a connection between the rotational frequency of the impeller, the shape of it, and cavitation occurring. however, it has been suggested in books by Callum Coats, that cavitation is a intense reaction caused in pressure-based propellers or impellers, and this is because of the poor movement of this shape. that this causes the impellers+propellers damage!

wikipedia also speaks of non-inertial cavitation, where a bubble in a fluid is forced to _oscillate_ in size/shape due to an acoustic field. this is used in ultrasonic cleaning of baths.

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

Dale Pond equates "Implosion" "Water-hammer effect" and "Cavitation" as being the same thing, which keely and schauberger and were working towards.

He speaks of it in these two videos:
