Hi Guys,

Should anybody be interested in, this page:

I'm now searching for a good mussel hunting workshop....

I measured the bells and got the following frequencies:
Bell 0 = 347.5 hz
1 = 917 & 941 Hz
2 = 2148 & 2198 Hz
3 = 649 Hz
4= 760 Hz

Anyone else get this ?

What are the diameters of your bells, and what is the distance from the rim
to the hole with the bolt?

I notice that your screen shot shows frequencies from 2000 hz to 20 khz. Are you sure
that there is nothing interesting going on between 300hz and 2000hz?

I've done experiment with my new cell
220V/0.7A dropped to 0.5A and a buzz sound occured when device was laying at the bottom of container.No sound when it was immersed freely in water..But still I saw no boiling even after a while :-(
However that drop in current usage is interesting.Also my inner bell was very loosely connected on threaded rod.I start to believe that sparks are cause of vibrations and sound.

I'm taking another stab at cracking this, but from a slightly different perspective.  I have new 'bells', whose fundamental frequencies are 1150Hz & 1630Hz.  Since everyone presumes that the 'real effect' is acoustic-based, I decided to use the frequencies above, rather than the 50Hz mains frequency.   I also now have a fairly accurate temperature meter - thermocouple probe is from another model, so I don't know how accurate the reading is, but since relative temp rise is all I'm interested in here, it's good enough!  Finally, I'm generating the frequencies using a laptop and Cooledit 2000.  Although max output is 2W, with the distilled water I'm using, actual readings are 6VAC p-p @ 55mA max.

Results:

Basically nothing of interest!  I have tried every combination of frequency manipulation I can think of, including frequency modulating either or both over a few hundred Hertz with a slow cycling time, in the hope of hitting a 'sweet-spot', to no avail.  I have also tried a few different positionings of the smaller bell with no effect.  While I am certainly not expecting to see any boiling take place at these power levels, given that the heater proportedly has a COP of 20, I was hoping to see some increase in temperature...  Only thing left to try is see if upping the input power makes a difference, but at this stage, I have lost interest in the brute-force "electrode heater" aspect...  If anyone can suggest another line of attack, please do
