If this were true, tuning would not matter.
What is your evidence for this remark?
I don't think you know your a**se from your elbow, DOCV.
Paul.

I did not say that there is no merit in finding out if the sound theory is possible only that the Davey claim of so called tuning is a red herring.
The theory is the same as a wave action, add another wave at the right frequency and the initial and consequent waves should increase. Whether this works between two bells is another story.

As for your remark it shows the vague appeals of a delinquent with meaningless abstractions, Grammar is not the measure of a man, but it is an excellent indicator of the quality of thought behind the words being spoken. Poor thinkers have always retreated behind ill-phrased, unclear statements, hoping their readers will do their thinking for them.
Time to leave this topic. Just like Paul it's going nowhere.

Perhaps you are right, but let's at least stop referring to the Davey heater as some amazing heating unit that uses audio vibrations to exert excess energy that heats water rapidly.

The Davey heater works by induction, it's as simple as that!

However if one wants to pursue whether an overunity effect can be realized by using his model of dome shaped objects then the following has to be undertaken.

Alter the mains frequency so that it is a harmonic of the 1st bell unit, not the other way around. The second bell will of course have to be a harmonic of the 1st and the distance between the two will have to be adjusted in case there is a dipole effect. This is the next logical step forward, not Himalayan singing bowls.

How then you explain the pictures showing boiling water and 8A current on the meter? Can you boil water INSTANTLY with 8A/220V? I can't.

Yes, NewAge. You're right.

What DOCV has forgotten, if he ever knew, is that the Davey heater originated from a
fighter pilot diving his aircraft, and getting a strange heating effect in the cokpit
if he could achieve certain frequencies with engine speed and various other rattling
components (cockpit canopy, probably).

The work has been replicated on many occasions, and if the tuning is good, then the
results are remarkable. Manufacturers have backed off because they do not believe that
it will be possible to pass safety regulations when putting mains electricity into water.

YES! Definitely Davey found an effect called magnetostriction : http://hyperphysics.phy-astr.gsu.edu/hbase/solids/magstrict.html

That joined with cavitation explain his device very well. The external shell is resonant cavity and probably contains very small holes. The internal bell is made from highly magnetostriction material. Both are probably somehow insulated to limit current but still allow magnetostriction.The effect is and contraction/expansion process of inner bell walls at 100 or 120 hz frequency which in correct shape should produce circulation of water between bells at around 3600 rpm, very similar to commerial cavitation heaters driven by electric motor.

look for 2 x grid current frequency !
