Peter Davey Heater

[Rapadura]

"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).

there are several technologies femradd , stnda , clai , het , pec
I speak of the heater H E T

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.
