look for 2 x grid current frequency !
Any octave of the grid frequency will do:
In the USA, 60hertz, 120, 240 480, 960 etc

In Europe, 50 Hz, 100, 200, 400, 800.

Davey's bicycle bells were around 800. About three frets up the highest string of a guitar

                         FW Woolworth's collapse

Special opportunity for people in Britain.

The demise of Woolies has its sadness, but they are selling off
EVERYTHING at half price.

This should include these stainless steel products:

soup ladles
woks
salad bowls
lids on waste baskets

All of these will be suitable for Davey research. I do not
know (and would like to know - any offers?) the relationship
between diameter and resonant frequency. But it would be
very interesting to get a large wok which could be tuned up to
50hz (a very low note indeed).

(My 30cm wok appears to resonate at B above the G# near
50hz). It would mean cutting a great deal off to get to 100hz.

I just realized what they are saying in video."high frequency sonic vibration" Huh!?
100hz is not high frequency. Do they know something or just guessing ? Listen carefully.

At the moment, I can't view videos, but I suspect that there are
two unconnected technologies here.

The key to Davey is not high frequency; it is tuning the bells to the
exact frequency (or an octave) of the mains electricity.

"The turbines are installed in specially equipped cylinder and driven by an acceleration force which is generated by a fixed amount of nitrogen. The projection of nitrogen into the interior of the cylinder causes the immediate start of FeMRaDD. The continuous circulation of nitrogen in the Zylinderinneren requires an immediate run-off by the visible and hidden elements in the direction of flow of another component, the recycling reservoir FDD / R. The reservoir appears in the form of tubes. These are filled with nitrogen and equipped with various measuring instruments and security. At startup, the reservoir is extremely accurate, and under precisely defined pressure on the nitrogen injection nozzles positioned exactly at least 31 in the interior of the cylinder."


Nitrogen generator?

What is this? One more S-C-A-M ??

This FeMRaDD technology seems very interesting, but I doubt that
it is Peter daysh Davey, which is, in its essence, very simple.

At $18,000, their gear is not that expensive. It should be possible
to find a hospital or similar to buy one on the grounds that, if it
doesn't work as described, they should be able to get their money
back under the "Sale of Goods Act" (UK law).

The links you gave in message 439 take us to Femradd. Do you have
a link to the H E T device that you mention?

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.

I agree completely with what you are saying...Notice that there is a
slight error previously expressed by in peoples thinking in this thread.
The bell would have to ring at 50Hz/60Hz - Under Water and
couple efficiently there. That is slightly different then having it ring at
50Hz in air. A big problem with it would be the different conductivities
of water from various locals. Also given enough conductivity it isn't too
surprising that the water can heat up fast, that is the principle behind
on-demand water heaters.

H.E.T. (Hydroelectrothermics on precise vibration )

H.E.T. is a space-saving device (90x129x295mm) which allows each type of hot water heating, old or new, hot water floor heating and indoor pool to work autarkically by using Hydroelectrotherm.

see below the link for the H.E.T. -device:

Their web site says it is patented. Does anyone know the number?
