carbedN,
[from my plumbing exp] cavitation is basically water molecule resonance in an enclosed space usualy created by a fast-acting valve, such as a washing machine's supply line cut-off valve. This is also commonly known as "water hammer". This affect can also be witnessed in supply lines not properly anchored (to code) and a simple kitchen or bathroom faucet. What's interesting is: the dude who discovered how to arrest "water hammer" ended up inventing the "hydrosonic pump"; which is supposedly 130+ % overunity. Ironically, it is not the spring and baffle surrounded by a copper tube you buy at Home Depot to fix water hammer (which gets soldered on the end of a vertical -> horizontal supply junction).
Link to the hydrosonic pump:
http://www.hydrodynamics.com/technology_review.htmthere are also numberous youtube vids regarding the hydrosonic pump & its inventor. If i remember correctly, the hydrosonic pump is one of the 3 inventions in the original "It runs on water" video, which of course, featured S.Meyer prominently.
The conspiracy theorist in me has noticed a pattern... whenever someone goes after big oil, auto, utilities - they get kilt, go missing, or otherwise cannot backup their claim. However, if you remain benign to these entities, you get to remain in business. To wit: HydroDynamics inc. and Hydrogen Application Technologies
http://www.hytechapps.com. It will be interesting (to me) to see what happens to the latter - since they say they are trying to adapt their "proprietary" generator to a car. Note in that video though that they go to pains to say that even though they
could run on 100% water - right now they are only doing a ~50-50 mix.
speaking of which - if i had 1/2 a ball, and 5K, i'd buy one of their "proprietary" generators - to take a look at the electronics...
