Hello,
Have you heard of the Peter Daysh Davey heater ?
#4 on this page : http://energia.sl.pl/ (http://energia.sl.pl/)
This is not an electrolysis device but a very simple device that produces heat + some minor electrolysis as a side effet.
I have built one from two bike ring clocks and got an efficiency of 1.12 (only measuring the temperature increase and the vaporated water) so very little excess heat but given the fact that in my setup :
- the two semi bowls were not perfectly spherical
- the two semi bowls were not accoustically resonnating at 50Hz frequency
I believe that someone with better equipment than me could give it a serious go.
The Pajak site mentions an efficienct ratio of 20 if properly tuned ! Not sure how serious this is...
Here is a link to a French forum where you can see pictures of replications and some more data if you can read French :

I like this idea, its really simple!
For a water heater reservoir in a house, you remove the current heater element with this device! But the replication I see from the forum link are not using the same piece. Seam to me that you need 2 different semi bowl, one bigger then another one, and its from the photo the material used is COPPER not stainless steel with bigger space between both bowl.
Here some photo of the real device

Hi Over_Unity_dot_com blokes!
My 2 cents about Davey:
http://freenrg.info/Sonettes_Davey/ (http://freenrg.info/Sonettes_Davey/) (In French sorry).
I made some devices and some measurements.
I got a COP slightly >1.
But it does not mean nothing according to the possible measurement errors.
All I can say is that my device seems slightly more efficient than a kettle. I did not manage to boil water (during my measurements) because I used a 16 amp circuit breaker that went out. :-\
BTW, as stated by Turtlefuel, it seems that you can get hydrogen along...
Anyway, a friend of mine told me that he once got an obviously huge COP (with a more serious='tight' device) (he is a retired Metal fitter/machinist) and that he could not believe his eyes!
So, IMHO worth to be studied.
For my part, I' m a bad machinist.... :-[

I have no problem seeing this device as more efficient than a standard heater element.
1. Current flow will create heat
2. If properly constructed, it will vibrate and cause friction.
3. It can possibly create cavitation effect too.
Mind you:
It is not an efficient way to generate hydrogen/oxygen and hydrogen/oxygen is an unwanted thing if you only look at it as a heater element.
I bet hydrogen/oxygen generation is the reason why the device won't go mainstream no matter what its efficiency is.
@TheNOP
OK.
Actually, if this device generates hydrogen (in any non efficient way) is it not a safe heating engine indeed!
But if this apparatus could be of any OU (COP>1) it is worth to be studied (NRG conservation-wise...) Would It not be?

I didn't sayed it was not worte experimenting with.
I was simply stating one reason why this device had been "suppressed".
Solving the hydrogen/oxygen generation "problem", in an ultra safe way, would be require in order for this device to be an accepted alternative to conventional heaters.
This stuff is pretty explosive...
Feeding a full cell with it seems to be technicaly not feasable due to how the gazes are produce.
Burning the hydrogen/oxygen for extra heat could be a way.
Natural gaz heaters safety mecanisimes could be use.
With other mecanisimes specialy made for hydrogen/oxygen.
But in my opignion, water pumps, showing cavitation effect, have a better future as alternative heaters.
the hydrogen problem can maybe resolved by using different material, obviously stainless steel is not the way to go

Is there any conductive material(s) that could prevent hydrogen/oxygen of being generate ?

Yes most of the replications are very poor, including mine :-)
If I knew where to find someone that could build one accurate replica with copper I would pay to get it done. This is weird device and even my simple replication showed some strange effects, one of those being that water was boiled faster than with a the kettle.
For NerzhDishual , I also did blew many fuses when experimenting. Try to use rain water in your experiments, then there is less electrolysis and less watts consumed.
If you use copper, keep it away from the positive charge and the O2... it'll turn black and give reduced conductivity in 5 minutes or less depending on current.
Been there, throwed 'em away.
