Peter Daysh Davey Water Heater Query

[MonsieurM]

I wish I knew if the can has to be Aluminium. I found an article that may be related in a roun about way:


Grain Refinement in Aluminum Alloys by Means of Electromagnetic Vibrations

very interesting....

thanks AhuraMazda

The other view is that vibrations also give rise to considerable agitation of the melt and result in the newly formed nuclei being distributed throughout the solidifying pool, so that crystallization takes place uniformly inside the entire volume. Moreover, the vibrations have much the same effect as turbulence, dispersing small crystals so that more of them grow, resulting in reduced grain size.

The sonic or ultrasonic irradiation of molten metals is mainly carried out with magnetostrictive, or piezoelectric, transducers (Figure 1). Coupling rods made of quartz, graphite, and various ceramic materials have been used to communicate vibrations to a molten metal, and these materials are attached to the transducer by special cements. However, such a technique presents several disadvantages. The oscillating rods are very rapidly dissolved when they are immersed into molten aluminum alloys, and this circumstance provokes an undesirable contamination of the metal. Moreover, the intensity of cavitation is greatest near the transducer or the coupling rod face; thus, the use of such a system is principally justified for the treatment of metal mixtures on a small scale.

reminds me of this post made by Dave

Can Scenario

Ahura,

Thanks, interesting. Yes, the aluminum can is the recommended variety of can. The inventor is studying other options too but hasn't explained them fully yet. There are also some different configurations that work with this method too but again, they haven't been explained to me. He has been using this device for some years now with no problems and he says it saves a lot on fuel costs. Utility services are very expensive in Serbia and so in this case needing to save was the mother of invention.

Your Replication

Chet,

I look forward to having your replication in the mix. Thanks for all your support!!

Re: Cheap & Readily Available. No, I just meant aluminum cans in general. I have an English chap looking for cans for me but so far no luck either. He's state side and like beer a lot, so I was hoping he'd come across some cans shortly. He drinks a lot of European beer but in bottles which doesn't help us much unless he sees some cans at the liquor stores.

Its a purpose built device,Perhaps not doing the same thing [in the same way] as Davey??

I have about another week of crazy schedule before I get back home again.
At that time I will be getting quite aggressive with my replication!

Thanks for your help Paul R

Can Scenario

Paul,

As you say, the can doesn't seem like the best choice of instruments but according to the inventor it works very well. I think we should stay with the can for the time being for several reasons. The inventor says it works well; they are much easier to fool with than some of the other alternatives; they seem to work well for me even when not tuned; they're cheap and readily available. Give this project a go with a can and see what happens, or wait and you'll see where I go with it. I'm studying alternatives in the ring department right now. Our contact is a very well educated smart chap who has I believe shared a very significant device with us.

Thanks for checking our thread out and for your input.

Best Regards,
Slovenia

I am not following this thread very closely and may get this wrong,
but can you not use something better than these moth eaten offerings?

Davey needs the object to ring out under the effect of the AC mains.
These miserable cans will never ring. They are crap. Could you use
some stainless steel tubing which, if held and struck, will ring out?
Try a kitchenware shop. Even a piece of a car exhaust tube would
be an improvement. (Now, Ramset, be good. Ask the driver first).

Sounds like we're going to need a good supply of cans!!

I think this is going to work like a hearing test ,with the goal being sensitivity.

Having the can ring at the lowest decibel possible will most likely yield the best results. My point is I can hook up my boys guitar amp and shake the can in the next room !,Its shaking it at resonance and low volume that must be a trick?

Practice practice practice!!
@Boguslaw,
yes I feel the same way about the copyright......
better safe than sorry!!

Thanks

Thanks!!

Thanks for your explanation Paul-R!!

IMPORTANT NOTE.

You can only tune upwards in frequency by filing and cutting.

If your item rings at a note higher than 50hz (or 60 in hte USA), then
you CANNOT tune it downwards to 50hz. You must go to the nearest
octave (not harmonic), which might be 100, 200, 400, 800hz etc.
(or if using 60hz mains, you would need ot go for 120, 240, 480 hz
etc).

In theory, it might be possible to add extra metal to get the frequency
lower, but I doubt that this would be a practical solution.

1- how do I tune my sonic boiler?
Response: Tune your aluminum can. The can must be cut to the proper length and the top walls sanded, thinned, until you get either 50 hz or 60 hz, which will depend on whether you are in USA or elsewhere.

Can Tuning

Hi Boguslaw,

I'm no musician either. No, I don't have a can tuned to perfection yet. I did have some success while I was still using the shorter American 12 oz pop cans to tune. I was vibrating the nail with regularity, but Mr. "C" said the can was bad because it was to short. I haven't video taped anything yet. My camcorder is a very nice Canon camera, but it's not digital, so I need to find a way to record it onto my computer so I can show demonstrations on this channel. I need some help on the camcorder deal now from someone. Anyway, I haven't been tuning cans for about three weeks now because of other problems around the house that needed immediate attention. When I get back to my can tuning, I'll keep you in mind and make a video for you and the others who didn't ask.

P.S.: I'll look up the instruction we were given on can tuning and post it again soon.

Best Regards,
Slovenia

Do you have can tuned ? If so - can you show us video how it should respond to 50/60 Hz when tuned ? I'm not musican and for me even ordinary beer can when empty resonate with 50hz here ....

I like your explanation.

Quote:
Am I somehow supposed to crystallize The can.?

It comes from the factory that way [The Big Factory=}

I don't pretend to know how it works, but if the professor says it bounces ,focus's neutrinos in the crystalline subatomic Lattice of Aluminum.

I'm good with that!!
AS far as tuning ?

Slovenia can explain it better
Thanks
