Peter Davey Heater

[devrimogun]

ND's and Sprocket's results prove that if something works it will work in many ways/shapes.
The reason that there is no instant boiling and for high current consumption is according to
the myth the tunings.

None of the experimenters tuned the inner bell and when the inner bell in not tuned, the second
tuning (distance) does not have any importance.

All according to the myth.

To tell the truth, I've lost all interest in this now, or at least till I get a clamp meter.  The realisation that the process is completely dependent on the type of water being boiled is a killer in my eyes, meaning that all replications will be subject to the vagries this will introduce.  Personally, I now have no doubt that a Davey heater will boil my tap-water much faster than a conventional heater, but as I reported in the DC electrolysis thread, my tap-water utterly destroys the SS in no time, so it has no practical applications in this part of the world.

btw, I also tried boiling distilled water with electrolyte added (bicarbonate of soda) - huge current flowed, so I pulled the plug rather than blow the fuse needlessly...

Hi.  I should just mention that my last creation had a nice 'dingggg...' off of it when struck with a piece of metal, and being a piston-type interference-fit construction is very easy to 'tune' - which I attempted to do by ear.  So, striking the outer dome, there was a point that was pretty easy to find where the inner one would also reverberate at its higher frequency.  Did nothing to speed up the heating process, at least as far as I could see.   Really, really need current measuring equipment for this though...

DOCV,

I haven't omitted this small little device attached to Davey lamp-like unit. That was my first thought and the reason why I tested transformer to lower voltage to 12V. I realized that step down voltage may be the key to avoid all potential dangers related to direct usage of main power.Obviously I did something wrong with my device or that wouldn't work that way.
Now I will concentrate my efford to second choice : direct immerse heating using mains power, however I'm a little scared about using it directly. Wish me luck!
According to some my other investigations of Peter Davey patent and video I think that there are many tips hidden in them. For example one of the most important tip is the knowledge that this heater does not work when not immersed in water,surely water MUST be REQUIRED PART of heating action.

My device is to large in my opinion but I wasn't able to find smaller SS bowls for casing assembly.Of course casing will be vented!

I have gone back and looked atthe video. The way he immerses the heater into the water which he does rather slowly. I think this is to ensure that a small amount of water enters the cavity to ensure a rapid boiling point is created by using brute force. Once this action starts there must be a draw of cold water through the bottom and hot water and bubles drawing out through thre top, this action is stimilating the resonance effect between the natual ac Hz and the tuned bowls. Once this starts the amps drop into a normal range of 2-4 amps. I don't believe that the bowls are loosly attached because if they were and either one touched would create a dead short.
I hooked up these sounds on an analyser and there is definately a beautiful resonance across the 50Hz modualting frequencies.
That little black ball that protrudes from the wires at the base bothers me, because it is doing something but not sure what at this stage. The best results I have achieved is a COP of 1 and maybe 1.1 but would need a watt meter to confirm.
What I can tell you is that the original patent is a red herring. The concept is there but he has had 50 years to modify it.
Tuning the bells doesn't improve efficiency, there is something more that i am missing. Will need to sleep on it for a few days to figure it out.
