Peter Davey Heater

Look what I found today:
http://www.hibberts.co.uk/wavanal.htm

"Four programs are available from this website. The most commonly used, Wavanal, is a program for anylsing the tuning of bells, using pre-recorded sounds or from a PC microphone. If you are new to bell analysis, this is the program you need. Rounds is a program for turning recordings of real bells rung singly into change ringing. I use this a lot in tuning experiments. Tuner is a spectrum analyser specifically designed to help with the tuning of bells. Finally, Pitcher is a simple utility for checking the pitch of bell sounds."

@all

...thought i'd better shuffle across to this thread (where's it been hiding?!) and see what's so intriguing that it's stopping my good friend NerzhDishual from helping me with a replication of a different electrical anomaly! 

actually, i think the single most amazing fact about this whole device here, is that it's inventor has not electrocuted himself before now!   

look at that water all over his work surfaces where he rests his three closely-joined metal electrodes, themselves covered in water, which are connected directly to the mains

you see, if you survive flying a Spitfire in wartime, the Universe has basically run out of threats to you!!

if you think Peter Davey's 'kettle' is cool - wait 'till you see his electric toothbrush  - ouch! 


seriously, now...

i'm sure you're all going to do excellently well in getting something going here - whether or not i've got anything useful to contribute - so i'll just throw out a few observations from reading thro' the thread

as someone said - it's not rocket science (meaning, i think, there are few components) - something can be elegant & uncomplicated but still profound

so, not many parts - and therefore, everything which is there is probably there for a reason just of it's own


- why the outer sphere?

  the outer sphere is certainly an earth shield (this agrees with the patent) - but it could also act as a containment vessel for the water which is being heated to keep it within the heating area longer - the water will expand & bubble as heating occurs - this will tend to force the water out from between the electrodes. the sphere will help to circulate the heating water around the electrodes before steam pressure finally forces it out of the sphere

  the patent has an outer shell with either slits or holes at each end for the liquid to enter & leave


- why is there an extra, slightly-raised, circular 'plate' at the bottom of the sphere?

  it could just be a small heatsink/stand to avoid ruining his designer-kitchen worktop when he parks the device - but i believe it covers a vent which allows water to enter the sphere - do we have any proof?  well, if you look at the Photo below, you can see a dark 'Twister' in the water below the sphere

  boiling water & steam gets expelled at the top vent & colder water gets sucked in at the bottom vent


- is the sphere aluminium?

  a) i suspect not - i understand it is difficult, to say the least, to weld aluminium!
   as the Polish Prof(?) mentioned, the welding would appear to be too high a standard for Peter to have achieved without some hi-tech equipment
  b) in one of the photos you can see the sphere has been created by welding two half-spheres - again, difficult to do with aluminium - if there are some 'bells' inside he must have welded the sphere around them - could they just be a rod & tube inside the sphere perhaps?
  c) in one of the photos, the silver appearance of the bottom plate on the sphere appears to have worn away leaving a 'copper'-coloured patch


- what dictates the acoustic 'tuning' of a 'bell'?

  i just did my own kitchen experiment with an SS draining bowl - it seems to me that a 'bell' doesn't vibrate just on, say, the outside or just the inside - i believe it vibrates most strongly around the rim - if this is true it would be the length of circumference of the rim which is a major factor in the acoustic pitch of the 'bell'

  when vibrating, a standing wave would be setup along the rim - similar to that trick of running a wetted finger around the rim of a wine-glass - you don't rub your finger round the outside or the inside to get the strongest vibration

  i wouldn't claim to be a musician - but i do play the bass guitar (low E string ~ 41Hz) and i can verify that the acoustic tuning is determined by the length of the string(= rim circumference length of bell); and the thickness of the string (= mass of the bell); and the tension of the string (= bell material)

  you can make two strings which are the same length, but different thickness, play the same frequency note - but you have to change the tension


- is the acoustic tuning of the bell important?

  i'm going to 'go out on a limb' here and say no!

  HOWEVER...

  if you read the patent it is made pretty clear that the electrodes are left loose 'TO VIBRATE' (as has already been pointed out) - special grooves are left in the end-mountings to allow this

  the patent shows many concentric tubes - all different in diameter -  so i believe, although they are all shown as the same length, they will have different resonant frequencies because they all have different masses & circumference lengths

  yes, it may well be that the frequency of the mains causes vibration - but in the patent the central electrode is a rod, not a cylinder and no mention of it being free to vibrate - so that should mean it is the outer 'bell' not the inner one that has to be free to vibrate with the current

the freedom to vibrate, however, was already a required element (oops, nearly a pun) of the heater design, before he changed over to bells - maybe there is some OU activity in this requirement?


- is the spacing critical? (ie. tuning the gap)

  not according to the patent - just vary the gap to suit the amount of heating required - especially if this is an inline water-flow heater (so we could expect: closer gap = lower water-path resistance = higher current)

  it's been mentioned in some reports that the spacing between the 'bells' has to be tuned for standing waves - for that to be true the frequencies involved would be approaching several-GigaHertz RF wavelengths (144MHz wavelength is around 2metres long!)


- is the device a capacitor?

  water has a high dielectric constant and can polarise strongly, which SHOULD make for a good capacitor - but because it has mobile ions present it is also a good conductor - so, it would be a very 'leaky' capacitor (got to be a pun in there somewhere!)

  H Aspden has a few interesting things to say about concentric capacitors gaining energy from the aether, so i wouldn't rule out some kind of aether resonance - but i doubt that we have to worry about grinding down bells to 'tune' it - the patent just says that the electrodes should be 'free to move from side to side as electric current passes from liquid'

  Davey's patent shows one central rod, 4 alternate live/neutral electrodes, and 1 outer earth cylinder but he says that any number of electrodes can be used (brass or plated brass in the patent's examples)


so, my take on this is that you guys can go straight-ahead & make some concentric bells / cyclinders / cones - just allow some of them to be loosely connected (physically); but they still need to make good electrical connection

interestingly, there's no mention anywhere in the Patent of power-in, current draw, or efficiency levels - the claim is that it heats rapidly and that the whole volume of liquid circulates by convection (ie. it's not a 'radiant' process)


Peter has obviously adapted the original patent design from cylinders to 'bells' - i suspect that it has nothing to do with the shape of his Spitfire's cockpit and heating up with vibration (did he fly it under water?!?)

i think it has everything to do with him playing the saxophone & noticing the resonant vibrations in objects around him when he played - and probably also to the greater availability of bicyle & alarm-clock bells than concentric brass cylinders after the war

...would be interesting to see if there's ever been an outbreak of bells disappearing from bicyles in Christchurch, New Zealand over the last 60 years


good luck all - i look forward to hearing about the COP results

i spent 2 years in CHCH , and my bell was never stolen, interesting pic in the above post, hes got three hands!.

that's what Evolution does to you after 75 years playing the saxophone

]...being serious here - just for a minute...

NerzhDishual uses 'bells'  and blows a 15(?)A fuse - Davey (supposedly) uses 'bells' and shows 2.5A

this causes me to think that vibration plays a different part altogether...

what if the vibration is actually disconnecting the loose electrode for part of the mains cycle?

it would then be acting like a random mechanical SCR - probably reduce the average current ... and maybe do some interesting things with the effect of the rise & fall edges of the switched voltage

in the news video, Davey admits he's holding something back

what? he using radioactive bicycle bells?! 

no, i don't think it matters if he uses bells or his dog's food tins - the important feature is that they're LOOSE (see how many times its mentioned in the Patent)

that would also re-inforce the thinking that the resonant frequency of the bell itself is unimportant - not easy to transfer acoustic energy into something loose - a spring needs to be anchored somewhere if you want it to oscillate/resonate (unless it has sufficient fexibility to its own mass ratio)

...just an idea, i'll shut up now
