Cavitation. The key to overunity?

[Koen1]

Well it is a rod with a gizmo on the end and there are visible wires...
... so for all I know it could indeed be one of those!

But check for yourself, just boot up the youtube video of
Thrapp and his spherical boiler and check the blurry shot at
about 8 minutes into the vid, where he pours the steaming
water out of the sphere and then re-places the rod+gizmo.

Which makes it even more odd really, since now he could just be
creating room temperature vapour and pretending to be producing steam...?

But let's just give him the benefit of the doubt and assume he's using
two of such transducers to produce a cavitation effect. ?

@Abba Rue 
Boy that transducer sure looks similar [always wondered that that probe?? was? Thrapp pulls out of the heater {not saying thats what it is but that shape always puzzled me.]

Your observation encourages me greatly.
Would be pretty funny if it wasn't proprietary and he bought it off the shelf at EBay
@Koen do you think its possible to produce cavitation with transducers?
One of my customers is a large boat yard ,I know they update the larger vessels all the time .
I Know they have a bunch of old transducers[the owner throws nothing out] I will talk to him on Tuesday
and see what he has
If I do find some matched sets I would gladly ship them to someone here no charge for experiments, or if any one could suggest a way this theory could be tested ,guide me through and I will do the testing

  I can't remember where but it was a radio interview with a person that said the frequency they use in the oscillators inside of compact flurescent tubes operates at 20 khz and that when used to vibrate water causes cavitation of the water that results in voltage only electrolysis of water.

"Which makes it even more odd really, since now he could just be

-the steam produced is real hot steam - look at the video, the steam is moving upward quickly, so it is hot steam not cold.

"But let's just give him the benefit of the doubt and assume he's using
two of such transducers to produce a cavitation effect"

-one transducer maybe, but two of them, not sure about this - how do you connect a transducer with only one wire? Look at the pictures that i provided (or at the video), there is only one wire on the top of the rod!
here: http://www.overunity.com/index.php?topic=6208.new#new

and there in that thread is also this video that i provided about cavitation with transducers: http://www.youtube.com/watch?v=0oNZcLyCR_Q&feature=PlayList&p=C9FA62002A6557CA&index=100
-and a copy paste of the comments on the video:

"HielscherUltrasonics (1 year ago) Show Hide
20kHz, ordinary city water at 20degC, ambient pressure, the pipe is approx. 140mm in diameter

SGiHunter (1 year ago) Show Hide
Is this process heating the water? Is there any hydrogen oxygen being produced/extracted at all?

HielscherUltrasonics (1 year ago) Show Hide
The basic law of thermodynamics applies: All power is finally converted into heat. Nothing is lost. In this case it is 1000 W of which 85% are mechanical output at the sonotrode. Given a volume of approx. 1 gallon, this will heat the water at approx. 0.2K/sec.

Nice job.

apeshkov (11 months ago) Show Hide
what is the peak-to-peak amplitude of the sonotrode?

HielscherUltrasonics (11 months ago) Show Hide
for this setup approx. 25 micron (peak-peak). The amplitude can be changed by means of different booster horns and electronically at the front panel. Therefore, amplitudes from 3 to over 170µm are possible using the UIP1000."

Ohh sorry guys, i might be wrong about the one wire on the rod thing - the video is so bad that noone can really tell.
So what we have here is just a transducer inside and one outside to put the thing in resonance. I thought it is much more complicated. Is there any cheaper transducer that the one seen on ebay?
