[@GodmanchesterGoblin]

Just an important FYI - most variacs do NOT provide safety isolation. They are constructed as variable auto-transformers. One of the output leads is directly connected to one of the inputs. The other connects to the variable tap which will be at any potential between the two inputs but without isolation. A separate mains isolation transformer in addition to the variac would be my recommendation.

[@davestorm6718]

I was about to mention this.

[@RobHaag71]

Yep, not to not pedantic but people need to not think they receive protection from an auto transformer (Variac), they are not isolators

[@deltab9768]

I think he was using it to control the voltage and because it had internal over current protection. You’re right though, variacs do not isolate from ground.

[@GodmanchesterGoblin]

@deltab9768 Not to be critical, and maybe you simply mistyped, but the point was it is their lack of isolation from the mains which presents a danger to the user.

[@deltab9768]

@@GodmanchesterGoblin what I mean is that mains electricity is referenced to earth. The “neutral” terminal is grounded. That means you can complete the circuit and get electrocuted by touching the live terminal while also touching any random grounded object (dirt, a body of water, damp wood or concrete, metal framing of a building, etc) As far as I know this is the most significant hazard that would be removed by using an isolation transformer instead of a variac or in addition to it. The hazard of electrocution by touching both terminals (or touching water with a voltage gradient across it) would still be there. The overcurrent hazard (which is explicitly stated as what the variac is supposed to protect against) would still be there. If I’m missing something else let me know.

About 40 years ago some scientists in Europe somewhere discovered that placing a length of brass tube about 4mm thick and about 100mm in diameter into liquid nitrogen. When they pulled it out they heard it resonating audibly. So they measured the frequency and then modified an amp and speaker to oscillate the tube at that frequency. The tube showed rapid temperature reduction until approaching the temperature of the liquid nitrogen. I think the show was called “beyond 2000” from Australia.

[@deltab9768]

Hahaha I saw this one! Just don’t touch the bath water until you unplug it lol.

[@HiltonBenchley]

After you mentioned the Ohmic Array a year or two back I planned to try it out, and still intend to. Heatworks say that the current in the heaters is something like 100 amps, which is fine for plumbed-in instant heat but not fine for home experimenting. I did find a formula that related the sizes of the plates, the distance apart, and the resistivity/conductivity of the water with the current and amount of energy imparted into the water. I worked out that it would take around 40 minutes to heat a bath of water with a current limit of almost 13 amps (one of the standard fuse ratings in a UK plug), although I ignored heat loss from the water. I did acquire some cheap carbon-lead batteries but couldn't find cheap graphite plates, so whenever I get round to experimenting I'll use flattened tin material (oddly, most tins are bad conductors, but tins that have contained condensed milk have a different surface finish and are good conductors).

[@PWARHOLM]

Most modern food 'tins' have a plastic coating inside. This might be why you do not find them good conductors.

Always informative and thanks for explaining the how the difference in AC and DC affect the process in different ways.

[@ColinWatters]

If a heating element is totally immersed in water all of the energy it consumes and emits must be absorbed by the water. A very small amount might be conducted (thermally conducted) out down the wires but that will normally be negligible. Therefore ALL simple resistive water heaters are 100% efficient. This means that anyone claiming to have invented a better water heater (resonant or otherwise) is effectively claiming to have invented an over unity (>100% efficient) machine which isn't possible. What a lot of these "improved boilers" really do is only heat part of the tank, the water nearest the heating device, so you get localised boiling. Any boiler that puts energy into a smaller volume of water will boil that smaller volume faster. This makes it look like its heating the water faster. To do a proper test you need to stir the tanks to ensure all the heaters being compared are heating the same volume of water with the same amount of energy. Eg Apply a known amount of energy, then stop, stir the water thoroughly so it's a uniform temperature, and measure the increase in temperature produced. A microwave oven is less than 60% efficient so its far better to heat water in a kettle than a microwave oven. The exception being when you only want to heat a small amount of water eg less than needed to cover the element of the kettle.

They do these with tubes with holes drilled in them to make steam, instead of hemispheres like this. Idk where they came from but my father taught me about it in the 80's as a small novelty to build in the shed. So I suspect it's older than we realise. There's nothing to do with resonance or magic, it's just cavitation. The 'ohmic' and the example you showed is just electric heating, the spinning hemisphere, etc, you'll notice the inner one has holes missing, that's causes the cavitation. It's better with cylinders because you push the water through it so it's way more effective.

[@Benoit-Pierre]

Electrolysis always happens, DC or AC, even in de ionised water. But deionized water is much less efficient at the start. But ... Here electrodes are much closer than usual. The very intense voltage differential makes electrolysis possible and intense because the low ionization is compensated by - high voltage - high proximity Plus : water ALWAYS has ions. Always. Water can be purified to be low ionized, but it's never 100% deionised. =» electrolysis happens here. But the Dumas effect does not rely on electrolysis. It relies on basic water being a resistive conductor. The trick to make water boil 5x faster is just ... Close plates. Close plates with large surface at less than 3mm will encap bubles. The proximity of plates will trap bubles on plates and surface tension will make bubles stick to plates. Once the bubles stick to borders of plates the water in the middle is trapped, and the water in the middle can heat up to 100 or 120° C via basic resistive effect. Because of bubbles, the water can't flow or renew. You produced an entrapped hot water zone that can boil locally. Outside the plates, the water remains at room temperature. That's how you obtain water boiling and.producing bubbles at room temperature. You are not boiling the whole glass, but just a thermally isolated part. It's spectacular because you are producing intense bubbles 5 times faster. It's just using proximity and surface tension to produce thermally isolated zones. At some point, it's also not far from Meissner effect. And of course, electrolysis helps producing small bubbles to isolate . There is no free energy. Just a nice story to fool people who enjoy confirmation bias.

The low resonant frequency of water if about 2,4GHz, as microwave oven works. If you apply more than 1,2V between 2 electrodes into distilled water, you electrolise it (voltage varies slightly depended on the distance between electrodes) . Its HHO gas what this steam is (losses heat up the liquid water). Electrolysis can happen with AC current, but gasses are mixed (NO DC needed). It would be interesting to see if this steam is flammable (carefully).

[@cyberknightmk]

Water doesn't have a resonant frequency. Microwave ovens heat water because of dielectric effect (fast changing of the electromagnetic field direction.) The current explanation is that the hydrogen bond progressively changes as frequency increases. Dielectric loss of water at 2.4 GHz is over 40%, but it'd require frequencies of almost 1 THz to get less than 10% loss (there'd be losses in the device, instead of from the water dielectric heating, so it'd be basically not worth it, even if terahertz technology was cheaply available.)

I am from europe and we had those untill like late 90s.. They were made out of thermal plastic and at the bottom were two stainless steel plates. Anyways they were marketed as quick way to boil water for coffee or tea.. But, i was a kid at the time and one time i put metal spoon in it.. Which was the time i realized that electricity feels like truck hitting you..

[@mikenezumi1705]

As others have no doubt pointed out: this seems like a pretty standard electrode water heater/boiler, apart from possibly the electrode form factor. Fun fact: this type of water heater was in widespread use for DHW in Eastern Europe in the "good" old days of the USSR.

[@kbbacon]

There was a hotdog cooker that used the hotdog as the heater. Basically each end of the hotdog was connected to its own electrode and the hotdog was the resistor.

[@amazingpower2761]

And that works very well also because of the salt as a conductor inside the hot dog sausage.

[@johnmarks2408]

Would this work with tap water ?

[@weorldedit]

If you make this into a water heater, the power would depend a lot on the conductivity of the water. In my city we have two different water supplies. So I would get about double the power of my neighbours in the next street over. Where a normal water heater produces the same amount of heat everywhere.

[@DrazenHosman]

Do not even accidentally try to apply it to the hot water boiler, the ELECTRODES UNDER VOLTAGE are immersed in the water, which means that all the water is under voltage, and therefore deadly, unless you have very good grounding in the apartment, you will just have to replace the fuses...

[@Vibe77Guy]

I once saw a few videos of the HHO electrolysis, in the presence of an ac magnetic field that supposedly increases the efficiency of the process by orders of magnitude.

Back in the 60's when I was in the RAF, we used to make our own mug water heaters. A couple of stainless steel knives, ''borrowed'' from the mess, with a piece of wood between the blades, thick enough so the handles don't touch, wrap insulating tape around the blades to hold them together, and pop the handles into a pint pot/mug of water! A cable with two crocodile clips, onto each blade and 220v plug on the other end. Plug in and switch on and in a minute or two you have a pot of boiling water. Remembering to switch off, and then remove the knives from the pot, and you can then add your tea or coffee! No resonance, patents or problems! Cost? Zero, as all the bits were scroungeable. .

Two spoons back to back, isolated, plugged directly into a 120 circuit, always worked well making coffee, ect, for prisoners.

How is limescale reducing the "efficacy" it might slow down the energy transfer but its not absorbing energy

[@dodobarbar]

Known old thing. But you explained it magnificently! Thumbs up.

[@officialdiadonacs]

I haven't commented in some time good sir, but these experiments are a lot of fun and I couldn't resist chiming in. Have you considered thermo-acoustic and kinetic resonant frequencies from liquid/gas phase shifts? There are Thermal differences in the cell and convections happening in the cell right? Getting spectroscopic analysis of the water as it's running with power challenging for us citizen scientist from my own personal experience.😅 Hope you explore this more in particular plasma phase transitions with pulsed DC.😊 Ofcourse, I am pretty bias in wantingto see more of those types of experiments. Thanks for sharing as always kind sir and I hope you are able to enjoy every present moment to the best of your abilities.

[@MacGuffin1]

Yeah , dont they have ultrasonic stuff too?

[@dontimberman5493]

So need to see at what frequency water boils the quickest. Also at higher frequencies should get less electrode erosion.

[@chaosopher23]

There is a kitchen gadget, no longer made, called the Hot Dogger or something like that. The hot dog gets put on two metal cones, and the lid is closed. 120 vac gets passed through the hot dogs, and in a very short time, you have lunch. It is no longer made. It was one of those Ronco or 'as seen on TV' things. It was highly unsafe.

[@felixaudet5860]

So how would you call this device, a capacitive ( rather than pure resistive ) heater?

[@jimwoods293]

Is it any more efficient or are you just boiling it locally in the water will it boil a litre of water any quicker or with less energy

[@adespade119]

I actually discovered this eftect, by coming to your channel and watching this video.

[@justrelaxing1501]

You sound like "Granville" "Open all hours" (David Johnson). And I love it!

[@antoniosanford4675]

Can the dumas device be made of aluminum, because aluminum wont tarnish in salt water!

[@derrelllipscomb693]

How do you isolate the mains power from the shower with this kind of water heater . . . that’s in direct contact with both?

[@terratrekker2]

Hi what is the voltage that you are using and what is the lowest voltage to make it work? Thank you for your time

[@KaliFissure]

Do you actually want them close? Or can a large distance force ALL of the electricity into heat? The higher the resistance, the more action held in between

[@theTeknoViking]

As always, a pleasure dear sir! Thanks a million for sharing your knowledge and positive energy (pun intended). 😁
