My two cents is that SHC should be off topic for LENR-CANR.org. Too
damagingly controversial. Obviously, it is anomalous science and on
topic for vortex-l though. Beyond that, I think it is worthy of
consideration as food for thought in designing amateur experiments.
Any *robust* energy anomaly is worthy of examination. That is the
second most important feature free energy experiments seem to lack,
after repeatability, robustness.
What could be more up an amateur mad scientist's alley! Throw random
ingredients into an acoustically/electrically/photonically stimulated
liquid filled vessel and look for transmutation, radioactivity or
massive excess heat.

Right now at Harbor Freight Tools they're selling a handheld
"ultrasonic
stain cleaner" the size of a dremel tool.
These contain a big paired piezo transducer running at 55KHz
bolted to a
steel "horn." All for ten dollars clearance sale! (down from $25)
This
price was at their retail store, not online.

The transducer in the above device is a fairly huge thing, like a
tiny
version of an ultrasonic welder. Not for kids, it probably delivers
internal burns. I've seen similar transducers sold on eBay for
$50. The
driver board has 3.3V logic and 6V mosfets, probably easy to pulse
it and
crank it up to much higher power. I'm currently drawing up a
schematic.
Drops of water placed on the steel tip will spray out as mist. If
swept
slowly over a polyethelene bag, it welds the sheets together (but
a crappy
weld, pops apart again if tugged.) If the tip is submerged in
water about
5mm away from a surface, loud random screech of cavitation is heard.
Also...
For nebulizing water, those "mist fountain" or "ultrasonic
humidifier"
devices can be found online for under $30. They run at much
higher power
than the above device, but run at 1MHz or so.

I ordered one of the stain cleaners, even though they look to be
wimpy, run by 4 1.5 V batteries. I have some giant (about 4"
diameter) cylindrical sonar transducers, which consist of about a 1
cm thick cylinder of yellow material sandwiched between cylindrical
layers of foil, if I recall correctly. They have been buried in
boxes of oddball equipment for years. From the attached leads it
looks like maybe they are designed to be stimulated by 1 kV or more.
Strange the sound is focused inward to a line, which would even be
better than a spot for muti-bubble sonoluminescence. I'm not sure
what kind of thing should drive these transducers with though.
Might be cool to drive one with a 60 neo magnet 20,000 rpm magneto -
powered with steam from highly stimulated boiling soup. Chicken
soup that is, of course. 8^)
