Peter Davey Heater

[Digits]

Hi guys this is Digits

From my experiments i have found that this is a very efficient way to boil water ad very efficient way.
the draw back are that if there are calcium in the water it will start to form scaling on the one bell.
So some times my water will boil quick and other not so quick due to the minerals in the water.

And yes I have to agree I found that if you have a bell not necessary at 50HZ but any frequency and you take a voltage and let it resonate at the same frequency it will definitely work the second bell will be a problem if ti's not tuned the same as the first.

two suggestion's though

You can always boil oil also for heating alternatives

And if your setup is tuned to perfection then swap the sinewave for a square wave pulsed at the resonant frequency,will this not be a great HHO reactor

Anyway this is only my thoughts on it

Good analysis sprocket!

This statement is untrue, as at worst, the Davey heater will act as an "Electrode Boiler", which are known to be up to 99.9% efficient - ie. more effecient than "element heaters".

I have experimented with a few builds and can state definitively that Davey heaters do boils water much faster than at least one element heater - ie. my kettle!  The problem with this kind of experimentation is that it can get expensive, electricity-wise!  I was recently thinking though, if 'resonance' is the 'secret', then experimenting with pure distilled water would be the way to go - a Davey/Electrode heater would use no electricity 'normally', though neither will it boil the distilled water!  However this lack of activity could be looked on as a benefit, 'cos if resonance is the answer, current would only start flowing in appreciable amounts as the heater was 'tuned' to the 'sweet-spot' - LC-circuit-wise!

Another theory:
correct frequency of electric field convert part of  water into cold steam breaking hydrogen bonds between water molecule, then sinewave AC bouncing molecules heat it up very fast. The first is crucial, and if this is correct it's strongly related to Stanley Meyer original water fuel cell.

Thanks but Frenette is more an air (space) heater. I needed an adaptable water heater.
Grenier is perfect.
But I got curious about the other one you mentioned. More information, could you?

Posted this, but it is not appearing, so here goes again.

Also, the resonance may cause dissociation into monatomic atoms and immediate
recombing. They can be noisy, and this points to cavitation. Remember the fabled
hydro vacuo machine of John Worrell Keely?
