I'm not sure I agree with that - while it may be 'synthetic', it is also a 'pure' sine wave, with none of the bizarre secondary frequencies that just serve to complicate things - just look at the 'real' sound spectrums of mine and ND's bells on this thread!  Also, any decent sound-chip nowadays will output a proper analogue soundwave, and not the digital 'stepped' constructs of days gone by...  So, if we are to assume that this works because standing-waves are being produced by harmonics of a 'pure' 50Hz sine-wave, it does not seem unreasonable to presume that 'something' might have happened with what I tried...  But it didn't - that I concede! :D

I still believe that it may work but sonic response I had ONLY when I Used mostly insulated inner bell mounted very loosely on rod and sparks occured between rod and bell (whcih had a little uncovered metal are near rod). Current usage was also small : between 0.5 and 2A and I saw a tiny chain of bubbles coming out of my device through very small hole near rod output.A buzzu sound was also generated.

Later I polished my inner bell and mounted tightly. Current rised up to 10A and lights in my house started to blinking but result was worse.

Still in both cases there was no immediately boiling action...


I decided to stop further test with this device due to dangers of direct mains current.I plan to build rotaty of oscillatory working device aka pulse rotor to test mechanical cavitation at safe 12V design ;-)

Why not try to pick up an inexpensive variac from Ebay? That way,
you could bring the voltage up from zero in a more orderly fashion.

To tune your bells or to check any audible frequency accurately and if you have speakers on your computer, spend no more money. Go to http://nch.com.au/tonegen/index.html and download their free tone generator. They have some nice software products at a good price, but for our purposes here you don't need them. If you connect an audio amplifier to your computer audio output you can use the nch software generator to run your Peter Davey heater at 50Hz or 50.01Hz or almost any other precision frequency you want. Try sine, square, triangle, sawtooth, pink or white noise. There is also a stereo option if you want to try running the two bells at different frequencies. Don't forget, if you run anywhere near 60Hz you can put a 60Hz transformer on the audio output amplifier and step your voltage/ current up and down. Be careful to protect your amplifier from inductive spikes from the transformer. Avoid sudden switching, rather adjust amplitude up and down gradually when turning on and off.

Hi Ggx9/Richard,

Thanks a lot for your informations.
Thanks also for 'resuscitating' (for a while?) this thread.

I have downloaded the software. It 'sounds' great.
For my part, and for the moment, I have given up my Davey's experiments.

I'm presently roasting some IRF250 trying to reproduce the
JL Naudin experiments about the Meyer WFC. (http://jnaudin.free.fr/wfc/)

Best

PS:  may I take advantage of this post to ask:
Is there any French/Breton guy over there?
How many are we interested in, and experimenting these 'OU subjects'?
I do not count in our best skeptics members of course. ;D

it's interesting to see the number of different experiments in progress which are all based around the use of electrodes in water

do people from 'grande' Bretagne qualify as Breton?  ;)

The essence of the Peter Davey system is accuracy. How accurate is this software? How accurate
is your mains frequency (the latter will be very accurate).

The best method is going to be tuning to the hum coming off your mains, either using a fat high
wattage resistor in series with a small loudspeaker or putting the LS on the end of an AC step
down transformer of the sort that used to be used for elderly modems and early mobile phones.
(Nowadays, they tend to rectify the output to DC, and are no good).
Paul.

More to the point, if the tones are generated by a crystal in the sound card, how accurate
is this component?

Maybe I am being a killjoy. We should try the software and see how it goes. After all,
a pair of magnificently useful soup ladles from Poundstrechers will only be two quid.

I was thinking and thinking and FOUND THIS :
http://youtube.com/watch?v=oLUeGX3hNpU

now scale this down add a tiny resistance heater around electrodes to rise water temperature initially to 100-120 F and what you see ? Yeah...it's Peter Davey heater ! Plasma reaction in small amount of water!

SERIOUSLY!

It's not the same thing. Cold fusion requires high voltage and also has nothing to do with frequencies (at least not yet).

hi every one I have also constructed one of these heaters and have to say you have got something here.

my amps ran at 3.5-4 after tuning and shifting the distance between the bells i managed to pull it down to 1-1.5 amps.
the time to bring my water to boil was halved.
i think with precision tuning we may do better.

i boil about a litre of water in 45s  to 1 minute don't know why the times differ though.

i am currently looking for better bells or domes and a better way to shift the distance.
i used two bicycle bells and PVC threaded rod this was the best i can do.

maybe ill have some good news in the future thanks guys for all the tips

Hi Digits,

Thanks for posting the results of your work.

Are you running 220 volts 50Hz to the bells?  Were you able to check the resonant frequency of the bells before installation? Earlier postings indicated the bells must resonate at the frequency of the applied voltage. I think it would be difficult or impossible to make a bicycle bell to resonate at 50Hz and I don't think it is necessary as your test implies. My impression is that the distance between the bells is most critical with regard to the frequency. Can you describe the water you are using? Is it tap water or distilled with an electrolyte added or whatever?

Good Job

Earlier postings indicated the bells must resonate at the frequency of the applied voltage. I think it would be difficult or impossible to make a bicycle bell to resonate at 50Hz...
...or any octave of this - i.e. 50hz, 100hz, 200hz, 400hz 800hz etc.

(in America, where they have mains at 60hz, it needs to be 60, 120, 240, 480hz etc)

A bicycle bell is likely to want the 400hz octave.

But cheap kitchen shops sell soup ladles and salad bowls which may well be much better.
With 50hz mains, you are looking to be a bit lower than G sharp, four frets up the highest
string of a guitar.

If you buy a set of pitch pipes for tuning a guitar, it will give you the G, and by
dinging the salad bowl in a shop, you may get in idea if it can be ground up to G sharp.
a salad bowl may give you a chance to aim for the 200hz or even the 100hz frequency.
Paul.

Hi Digits,

Thanks for sharing.
Your results sound very interesting.
Our amp consumption is very low and the fact that you
could, after tuning, had lowered you amp consumption
while halving the boiling time is amazing...
Can you use a watt meter?

Could you please post some pictures?

Best
