Peterae - I see a relationship here that may take a little while to explain. I'm going to have to describe what I see in my own lumbering way because I can see no way of explaining the relationship simply.
This one might well get me or loved ones hurt - I just hope not!
I have all night courtesy of a twisted sciatic nerve and much to say so I'll try and play the piper and hope people kind enough to read and consider what I write , can follow.
What you present here as 'The Trompe' I also see as a Kissing cousin of a machine developed by battle of Britain Spitfire pilot Peter Davey and which was introduced to the forums some decade or so ago.
Now I'm not really biased regarding any particular inventor, and it is the inventor I tend to study rather than the particular contraption. However in the case of Peter Davey I make an exception as you read this and understand what this man has done and how and why he did it I'm sure you'll agree he's a class act - a diamond from the last generation . let me remind of the short clip that did the rounds - then I'll do my very best to take this to pieces for you
https://www.youtube.com/watch?v=xFlQ6z_qqoUI'm sure you remember it, It was a frustrating enigma across many forums for months. Its actually (believe it or not) the inverse of this trompe machine. I need to tell some of Peters story to relate how they connect so I crave some patience for something that at first doesn't seem to relate at all.
Peter was a volunteer pilot from New Zealand unlike British nationals who were conscripted the 'colonials' were formed into 'volunteer' squadrons. The losses experienced by Peters city of Glasgow 602 squadron which was seconded to the defense of London and the south east were high,very high.
It should be remembered that Britain was fighting entirely alone against the axis powers through this period. despite very heavy losses 602 squadron kept up a kill rate second to none
Peters 602 squadron
with a war time death rate of circa 50 % each year young pilot officer Peter Davey rose rapidly through the ranks here is fg off Peter Davey in 1943.
Peter was a skilled and cunning adversary. those that didn't develop essential skills very quickly didn't survive the early stages of this air war.
Now let me give you a question to ponder , do you think one of the few, a volunteer one of the few at that, who flew through that bloody maelstrom. a pilot with a full service pension along with his state pension would concern himself with lies and trickery at the end of his life ? your a poor judge of an RAF officer if you do!
Just for your interest here's my grandfather in uniform who was flying heavy bombers at the time. he also was also very lucky to survive that war. It also explains perhaps why I'm a little biased towards the RAF
I find it frustrating when clever skilled people of the caliber of Peter explain exactly how they developed a machine and lots of supposedly clever folks don't listen, don't study, don't pay attention and then go and do something else very different anyway , from what I saw in that era across the forums people might as well have knitted a sock puppet and expected it to boil water
In fact think a certain "Serbian professor" did and then sold every one else the story.
Peter tells us he first developed his idea flying his spitfire, Peter tells us he discovered he could with careful adjustment find a speed where the cabin warmed up - a distinct advantage up there,its bloody cold .
Imagine now if you will a canopy thats a tad leaky and a fuselage with a few patched bullet holes, or if its easier a house with back and front door open, there is a vicious through draft.
If you happen to be thousands of feet up in the air plodding along at two or three hundred MPH its a cold unpleasant through draft.
You can't shut the front or back door in this case but what you can do is alter the wind speed. Just as Peter explained with regard to his saxophone there is a pressure difference between the mouth piece and the horn. Understand that the same thing applies to his device and his spitfire - he tells you so !
Inside his spitfire he discovered he could carefully adjust the speed until he had created a standing wave of air. A standing wave in which he 'a solid lump' was in a nice warm wind free trough. The same applies to the trompe but of course reversed - maximum turbulance is wanted at the bottom of that hole! maximum air released
Peter then was considering air at either end and a solid in the center (himself) With the Trompe we consider a solid at either end (water) and air in the middle , hence I suggest to you one is the inverse of the other.
Both rely on this balance call it resonance if you wish however its absolutely nothing to do with 50Hz 60Hz or indeed any Hz at all Peter told you sound - a longtitudinal wave in this context .
I invite you to watch this clip I shot at the time, It is crude, and the camera none to clever . In fact its just a web cam turned at this dangerous abortion. It is simply two spoons very close together thrown into a jam jar of tap water and plugged into 240 volt mains . There is the refinement of an ammeter with a 10 amp FSD its not an action video It was never meant for broadcast but something very important is happening here which I totally missed. I guess so obsessed with overunity (which this certainly isn't) I wasn't paying attention.
Please watch the ammeter very carefully although I'm ashamed to say what I missed is so painfully obvious its hard to miss -- As this is connected to the grid, the mains voltage is very stable that being the case power input is directly proportional to current at all times .
https://www.youtube.com/watch?v=teAksvLyaJ0 Look at the variation !! particularly when boiling furiously the current and so power consumption drops away to almost nothing . This very importantly is a non ohmic circuit it fact its not really a circuit at all is it? Its a variable capacitor. oddly the significance of that didn't strike home.
Even at this early point surly you can see if you have a pot of furiously boiling water whilst using no power you could in theory wrap a pipe around it and feed say a radiator by indirect heating. For those who whine and bitch about COP>1 systems you couldn't get closer to one without it biting you on the arse! However -
Peter went a few steps further, the water was always boiling in Peters contraption regardless of its actual temperature.
just as the air is always cold in the trompe - again its the inverse you see ! tending to hot - not to cold
I hope you also noticed that where the spoons I threw into the jam jar were closest together (Just before the bowls) boiling was localized and instant its also very important to Peter Daveys plan as you'll see.
Peters Device was exactly as he described it to you, but no one paid the slightest attention . It was just the same as his spitfire and his saxophone.
a hole at either end and a controlled vacuum in the middle - exactly the inverse of 'The trompe'
please allow me to show you. here is Peters device. I've blown it up a little for you
Peter tried many times to get this patented I think we know on this forum that was never going to happen . Those who have had dealings with the patent system will know secrecy is all important. Peter already has a few patents to his name, he knew the procedure . appearing on national television with such a device was an act of desperation by a gallant and sick old man who's hope was to leave a legacy for his family. His son (also called Peter) is retired himself now anyway.
I'm almost loath to reveal the cunning that kept this man alive above London whilst dancing with Messerschmitt's the same cunning that has hidden his device from so many 'clever' people for so long, Anyway lets start.
The ball is made of stainless steel the two hemispheres are welded together so as to be 'air tight' Peter has painted the ball in an effort to disguise what he has done. (use iron or steel and it'll quickly blow up because of free ions transmitted to the water)
look long and hard at the bottom of Peters ball, do you see the slight rust mark on the cheap paint?
That is a hole, a very measured and precise hole into the ball . It is the canopy of the spitfire or the mouthpiece of the saxophone - Its where the water enters in a throttled controlled way. Its a specific size! It has a flow rate
Just as the trompe has a flow rate.
Do you see the little hat on top ? hidden under that hat are a few more little holes . holes to let the boiling water or steam out . the horn of his saxophone or his patched fuselage if you like.
I'm none to good at drawing and I'm ashamed to say when I was helping PJ kelly with a few odds and sods he tried very hard to teach me paint - it was a miserable failure . anyway heres what I think your going to find inside the secret ball quickly scribbled for your enjoyment - Those plates are very close a matter of a mm or two. Young Peter records he once tried to re-heat some coffie with the contraption . I think you can imagine the result !
here's a random video off the net showing tap water and spacing of 3mm
https://www.youtube.com/watch?v=_iiWGel3q50 try to absorb my scribble and we'll go through whats happening, then folks can pretend they cracked Peters secret ball
all by themselves whilst I get shot at.
Watch again if you would please Peters short clip and take special note of the hesitation as he first introduces the ball to the water, here it is for you again
https://www.youtube.com/watch?v=LTV85J2QHj0Its not old age its very intentional ! a little water enters the ball through the hole in the bottom - It boils instantly, just as you saw with the spoons I showed you !
Steam fills the ball that is what Peter is studying , It takes but a second and he sees a puff of steam rise from under the hat
in goes the ball. That ball into cold water creates a vacuum. - naturally the inverse of the trompe again which creates pressure!
here's an example of whats happening filmed for primary school children that being so I'm quietly confident that one or two of the finest minds on our forum might also be able comprehend what is happening
https://www.youtube.com/watch?v=j0TQxYemrggas this device just like the trompe depends on pressure (but of course the inverse) - that is negative pressure do you happen to recall what happens to the boiling point of water at low atmospheric pressure ? no? any one tried having a cup of tea up everest ? here's what happens --
https://www.youtube.com/watch?v=8lyqFkFsH28taken to a further extream
https://www.youtube.com/watch?v=I5mkf066p-Uremember the spoons ? what do you think the effect of low pressure would have in that situation ? again let me show you with only a small battery applied to plates in water inside a jar thats been evacuated
https://www.youtube.com/watch?v=msr0TOHuAS8&index=7&list=UU-6Xkt8OXH0ThIeetHov04ADo you remember I showed you water boiling furiously betwixt two spoons whilst drawing a feeble ammount of power?
The commentators didn't lie , neither did Peter the water is boiling instantly just as the clip shows.
Heres a graph vacuum to water boiling point point which might help you see the curve peter tried to follow
https://www.engineeringtoolbox.com/water-evacuation-pressure-temperature-d_1686.html so none ohmic and this certainly isn't a straight line graph is it ? time for maxima and minima and a bit of double differentiation I guess -- anyone remember how to do all that stuff ?
Peter's contraption of course sailed alongside that curve although I dare say as a fighter pilot Peter Davey didn't sail much at all! however history records he and his spitfire were heavily involved in air sea rescue towards the end of the war. very good eyesight it seems.
now you have all the pieces - keep the water boiling and you use no power or at least very little.
This Witts thing might also appeal to you it seems like the same patter to me.
https://www.youtube.com/watch?v=oZoiY3FvxKo The opposite action of a trompe I think you'll agree? Kindest regards Duncan
