Cavitation. The key to overunity?

@ Chet:

Yes I saw the shrimp video.  What I can't figure out is how a creature evolves to end up with something like this.  It was an interesting video.  Do I think what Mr. Thrapp claimed he did is impossible? No.  I just don't believe he has accomplished it as he has claimed.  I hope he proves me wrong one day.  We spend a lot of money in this country heating water.  In fact, the only thing a nuclear power plant uses the plutonium for is to heat water.  If this did indeed work, one could have huge spheres producing steam to run turbines.

@Spinner:

Yes, I remember your post in Mr. Hardy's topic.  It sounds similar to what Sparks is saying I believe.

@ Sparks:

What you describe sounds a whole lot like the process of refrigeration, compressing a gas and then expanding it through an orifice.  I know it is not the same as liquids can not be compressed.  I remember in my jet skiing days the jet, basically a ducted fan for the water using a series of impellers, would not work well in the rapids of a river I was running.  Seems it would cavitate when it compressed the air bubbles dissolved into the water from the action of the rapids. It lost a lot of thrust due to the bubbles being compressed, you could feel it.  Again, I know this is not your example but that is basically my only hands on experience with cavitation.

@ Spinner:

How old is the "Chain Reaction" movie?  Old enough to where I might watch it online for free?  I will look for it.

@ borg:

That was cool!!!  After watching that I found this next to it.  A propeller producing cavitation.  Also it looks like it produces light, but maybe it was the lighting when making the video?

check this video out  http://www.youtube.com/watch?v=ONQlTMUYCW4  it shows some more detail about the shrimp.

This process could be replicated with a high pressure nozzle under water in short burst or longer burst depending on  the water volume of the nozzle!

a simple way to test this is with a compressed water tank with a high speed valve.

maybe a simple high speed valve could be created with a disk with spaced holes and a motor to turn the disk valve.

This also reminds me of the effects of a whip! but under water.

maybe something like a whip can be incorporated but underwater to cause cavitation at the snapping points
