Davey's Water Heater

[Jetijs]

Jason, that is an interesting idea

[Karl_Palsness]

Thanks for all the great ideas! This is what I am thing of doing.

1. I am going to use my Function generator to make the sign wave to drive a match pare of transistors to drive a transformer.
2. That way I don’t have to match the “Bell” to the frequency I can match the frequency to the “Bell”
3. I have found the perfect bell, but it is bigger than he used. It is those double wall stainless steal insulated cups made of spun matched SS. I found them at Ikea and also at “Canadian Tire”…but I have seen them all over the place. I also found a dinner bowl also that same way.
4. I took a grinder and ground the weld joint that welds them together and the some apart perfect.

I will take some pictures soon and post those….I got my transformer from an old UPS power supply…lol. I have been collecting them for a few years now.

Will keep you informed with what I learn

Push Pull Transistors

Hi,

Jetijs, a car audio amplifier may be a good idea, but the push-pull transistors would work fine too, as I posted on this thread before. Just for saving $$$

Elias,
I showed your diagram to my electronics guy and he said, that this circuit only demonstrates the principle but in reality it is much harder to get a good sine wave with no rippled or distortions.

wondering temp

Elias:
Did you have any result about davey's heater? I saw several times of his demo video, and He hold the cup with bare hand when water boiling?! check singing bowl, when people touch bowl containing the water, the water "boiling", but temp is not changed or little.

Mark,

Not really, because I didn't have time to make it, I am working on other projects right now, I only used two bowls and connected them as described and applied voltage to see if I could produce any heat, and it did boil the water pretty fast, but, I suppose I was drawing about a kilowatt from the mains, I didn't look at the amps. I am pretty sure that It would work more efficiently on a particular frequency, but I need the time to do that. I would in the coming months but not now.

prelim data

Hi, everyone, I just did pre-experiment for Davey's device, any comment is welcome.
I put two cans in the water separately connected with 110v AC, testing current(A), and put smaller can(beer) into larger one, the gap between two cans is about 1mm, and testing current and temp(B).
Results:
(A): 0.8-1 amp with gap about 5 mm, closer, higher current, no-feeling temp change;
(B): 6-7 amp with gap 1mm, felt water warm surround(about 40-50C after 30sec).
A large of amount bubbles come out of gap, they look like "boiling", and I guess it is H2 and O2 due to electrolysis, but I could not explain why AC can do the same work as DC.
I did not tuned "bell", just for your reference.

heya. this stuff interests me quite a bit. especially the notice of him being a spitfire pilot and the motor + propeller hitting resonance causing an influx of heat into the cabin.

the images ( i ripped them from the slideshow, to: http://www.scene.org/~esa/merlib/sax/
), peter davey is showing the lowermost G-note on the piano and a book on piano frequencies, and i asked around and seems that a low G is 49Hz, very close to the 50hz electricity that he gets in new zealand anyway.

it would be lovely to know what kinds of higher harmonics he is creating (with that older method of his) with that 50hz electricity resonating one bowl and 50hz resonating another, smaller bowl, and the distance being adjusted to hit the heat-point.

heres the news-broadcast:
Peter Davey's Sonic Resonance Boiler from February 2008

i really hope this thread will keep alive

Have you seen this?
YouTube - Overunity free energy water heater from WITS

[bugler]

I have a doubt with this Davey's heater.

The whole thing is electrically isolated or if I touch both bells I will get an electric shock?

Not sure whether I explained myself?

A small attempt

I tried a build, with two stainless bowls. All I made was hydroxy. I probally hooked things up wrong. I am going to keep my eye's open for bells. I was thinking the little ringing bells i use to see in church would be similiar to what Davey was using. They are always laying around @ thrift stores.

Hi all
I have started to experiment with moejoe cells (the advanced design of joecells) and I noticed that the hemispheres from the moejoe might be perfectly suited for this water heating experiment. I already have a function generator, all I need now is an audio amplifier, I suppose 100w should be enough. As soon as I get it, I will do this experiment and inform you. Also I should get an IR thermometer.





Thanks,
Jetijs

Hello all,

I came across Mr Davey's heater whilst searching for 'heat water via resonance' on Google. I believe he has something, sound after all is energy
I don't understand why anyone would try this without tuning an element first, the whole point is resonance and setting up standing waves between a tuned element and a buffering element, well at least thats the way I understand it.

I look forward to watching and contributing to this thread. I have begun building a resonant water heater using a Tibetan singing bowl as my main element. I've already quickly found the resonant frequency of the bowl using my ears which were amazingly accurate I tuned a software signal generator to it at 1259Hz and when I analyzed a recording of the bowl it was 1260Hz according to my spectrum analyzer, so my ears were pretty damn accurate I'd say It does help though having an ear for music, I've been a guitarist for 20+ years and am very used to tuning my guitar by ear.

What really excites me about using a resonant heater element is what happens when you feed it harmonics too. Will that increase the efficiency even further??, my guess is it will because there will be more energy in the waveform. My bowl has a base resonant frequency and there is also another higher frequency that it resonants at which is complimentary to the base note. This provides a richer sound rather like a saxophone does.

This article might prove to some that there is no electricity involved:

Very interesting reading AhuraMazda! I'm even more convinced now. I did wonder if it wasn't cavitation occurring in his heater. Makes me wonder if the hydrosonic pumps patented by Hydro Dynamics

Hydro Dynamics, Inc - The Solutions Company

aren't also in some way tapping acoustic resonance to bring about cavitation bubbles.
