some time ago posted on this forum (if memory serves by Peterae) was this clip by Bill Mollison which fascinated me .
https://youtu.be/-9NqqDL6bkk
If cool is created by the process of isothermally compression as Bill tells us what of the other end of the scale ? Does isothermally expanded water create heat ? It seems to me yes and very effectively but by all means read experiment and make your own minds up.
The process explained quite a lot of the so called 'sonic water heater' devices for me.
So I decided to make this contraption
http://dnp.s3-eu-west-1.amazonaws.com/b/b9/Davey%20044.jpgThats a carb jet you see fitted to the bottom likewise under that dome on top . There is a controlled 'throttled' vacuum involved here
I could of course make a video and claim 20x over unity or anything else for that matter . (Thats what Dr Jan Pajak claimed for Daveys heater)
Video's are the easiest thing to falsify and so I'm not going to do that - rather explain how and why I made this thing . I have already outlined how this thing works to a friend of mine - Jim. so rather than rewrite everything I'll take the liberty of copy and paste the email I sent him.
Hi Jim I think your going to enjoy this anyway I'd like your thoughts on the latest bit of investigation I have been working on . I decided to revisit an old chestnut with my own methods which tend to be very different from other investigators simply because I tend to focus on the researcher and not until much later the machine.
It so happens that this particular guy was a WW2 spitfire fighter pilot involved with a squadron composed of volunteer pilots from the British colonies.
Unlike British nationals the colonial fighters were not conscripted, the 602 squadron suffered a 50% attrition rate during the bitter fighting during the period now known as "The battle of Britain" as these islands stood alone against the axis powers. Peter was an accomplished pilot with guile and cunning and obviously gifted with some lady luck ! - He survived.

Peter was also an accomplished musician playing sax ,trumpet and keyboards solo and with Dance bands of the era

You might wonder Jim why an obscure Spitfire pilot has caught my attention , let me first introduce you to one of the patents that actually was issued to Peter Davey before we look one that was never going to be issued until hell froze over . (and why)
This is a diagram of Peters first water heater taken from Patent NZ92428 issued in 1950 it is somewhat reminiscent of an old beehive trimmer . (anyone remember them?) Mains was connected and it heated water reasonably efficiently. One of the first rules for patenting anything Jim is 'keep it secret' Peter would have been very aware of that. He further developed the crude heater shown in 1950 unfortunately he broke the unwritten law. He went flying well over unity ! It was Peters intension to leave his invention as a legacy for his family but as you can imagine a simple COP>1 machine was never ever going to get a patent.
For over thirty years Peter's train just kept hitting the buffers. As a now sick man and in absolute desperation he committed the cardinal sin - He showed his contraption on National television in the hope that an investor would assist him in pressuring the patent office. He attempted to hide the operation of the heater (very successfully as it happens) I guess you don't avoid packs of ME109s without a certain amount of guile.
https://www.youtube.com/watch?v=KFKxJyFiNvcThere is an awful lot going on here Jim and nothing much to do with spoons ! at least not directly, very soon after I watched this clip I put two stainless steel spoons together in a jam jar full of water and plugged it into 240 v mains. It was never meant for public viewing but I did point a web cam at it, The meter is switched to 10 A full scale deflection. A little boring but its not meant to be entertainment ! (a pity I didn't have a mic ,the sounds amazing when you close that gap) closing the gap also gives a better capacitor C= A/D
NB - 1/ Unlike resistive heating its far from a straight line graph. (you've gotta walk that tight rope)
2/ A thing I very foolishly missed that's really important is when the waters boiling furiously the current draw drops away to almost zero, watch it yourself although the needles not easy to see you'' you can see it in the mirror an the back of the meter scale.
https://www.youtube.com/watch?v=teAksvLyaJ0&index=30&list=UU-6Xkt8OXH0ThIeetHov04AI'm going to go over this contraption , I love what this guys done . what of water? is it an insulator or a conductor ? Have I just made a very good capacitor ?
https://www.scienceabc.com/pure-sciences/do-you-think-that-water-conducts-electricity-if-you-do-then-youre-wrong.htmlkeep at the back of your mind Jim - your not particularly interested in 'water' rather whats inside the bubbles of 'boiling water'
which seems to make an excellent di-electric and terrific capacitor . anyway to continue -
You saw water boiling furiously whilst drawing little or no current and little or no current = little or no power !! now consider putting an indirect heating coil around a container boiling just like that and feeding a heating radiator.
Ah Oh dear we seem to have broken the law already Jim - shame ! Peter went much further and I love the crude engineering and cunning.
here then is the amazing truth just as the reporter says " as soon as the contraption touches water it boils" instantly (almost) Lol I wish I had the maths to make simple pressings of this machine and scale it - Perhaps you can ?
So here's what Peter's done . You have seen that when boiling no current is consumed here then is the twist , At what temperature does water boil ? 100deg C ? It very much depends Jim on air pressure watch what happens up Everest . (for instance)
https://www.youtube.com/watch?v=8lyqFkFsH28https://www.engineeringtoolbox.com/boiling-point-water-d_926.htmlso at what temperature would water boil in a vacuum or partial vacuum ? and just how did peter create a vacuum ?
Let me invite you to watch these demonstrations for school children Jim because together they show just what Flight Lt Peter Daish Davey devised , I think when I put the pieces together for you you'll be an admirer too.
https://youtu.be/j0TQxYemrggDo you start to get the picture I wonder ? to offer a clue when the distance between those spoons (remember the spoons ?) is closed right up the water boils locally and pretty much instantly ,
Watch then what happens to water in low air pressure
https://www.youtube.com/watch?v=I5mkf066p-UThe players are all now on the stage Jim - lets see how Peter fitted them to their parts, when boiling little or no current is flowing is key.
Do you see at the bottom of the bulb were the flat plate is welded to the stainless steel ball ? look carefully at the center of that plate . Do you see the rust ?
That Jim is a hole right through the plate and into the ball itself. Its a small hole because the ball is a controlled vacuum. there are some more even smaller holes under the cap on top of the ball to control the vacuum/pressure.
just the other side of that hole inside the ball is the positive plate, the ball itself being negative (or ground) which is the same thing. Watch the video again as Peter puts this contraption in water again, notice how he hesitates - a small amount of water is boiling between the plates and the ball is quickly filled with steam . Peter then puts the whole thing into the water, The steam condenses and a partial vacuum is formed. The sequence is formed. watch again as Peter hesitates dipping the ball into water -
steam is formed pretty much instantly - the ball is plunged in a vacuum is formed
https://www.youtube.com/watch?v=KFKxJyFiNvc Clever little shit don't ya think ? here are some video's and links in support and akin to this system
First from the school of Ronald Brandt (Tesla's last assistant who took refuge at Witts )
https://www.youtube.com/watch?v=oZoiY3FvxKoJim Griggs
https://youtu.be/uaVqxXsQsSQAnd of course water boiling with ridiculous ease at low pressure using plates . very low voltage and milli amps
https://www.youtube.com/watch?v=msr0TOHuAS8&index=7&list=UU-6Xkt8OXH0ThIeetHov04A If It helps Jim here's a rough sketch of the construction of that 'magic ball' (if my scribble helps )
http://dnp.s3-eu-west-1.amazonaws.com/b/b9/sketch of ball.jpegnow to ponder how to get at the physical dimensions such that they can be scaled
there are some draw backs to this system 'as is' - its really only good for a fixed quantity of water (and one shot) and the system gets less efficient as the bulk of the water gets close to boiling (loses the ability to condense the steam)
I'm assuming this is why the WITTS version is a carefully measured amount of water, over a very specific time . perhaps with some thought it can be advanced to cycle - . -- Kind regards Duncan
