Magnetic water pumps with no moving parts recently took the internet by storm with multi-million-view CZcams videos showing you how to build one at home. While most of those videos are fake, MHD isn’t. It’s a very real field of physics, and its applications are super surprising. So how do they work and what might they allow us to do? Let's figure this out together!

Hydrogen would be my favorite fuel.
I'm surprised you didn't mention the movie, "The Hunt for Red October"...
I am absolutely disgusted that you can say your electricity consumption averages 1.8kW 24hrs a day, 30 days a month, without any sign of guilt on your face.
I have NEVER in the 53 years of my life used more than 60kWhr a month for a house and engineering shop combined.
Even if you drive a battery EV you would need to drive 5hrs per day to consume that much if its any kind of efficient.
I operate a cruising yacht with all systems including electric Auxiliary, and tender, with two crew, and we usually require far less than half a kilowatt hour per day of solar generation.
Stop pushing for exponential growth of consumption and screwing the planet with your pathological obsessions with compensation for you inadequacies by excessive displays of obscene extravagance and disposable consumer culture.! 😝
I think you said "Megawatt" where you meant "Kilowatt?"
I can understand you don't w
LK99 is a bust now isn't it?
Yeah, sadly it is.
Link?
Tis the reports they were citing are over 14 years old and been disproven multiple times its a good dream and maybe a reality someday. I think it's because the tech industries know how revolutionary a material like lk99 would be and they want to promote interest in the topic as much as possible
It always was...
Plug, plug, and plug away.
The CONDUCTIVITY of the fluid is crucial. While MHD is useful for some fluids like liquid metals or molten salts, even seawater is a bit sketchy. And you can pretty much forget using MHD pumps for salt-free freshwater.
But as always, there could be a place for this, and your videos are great as always.
Would it be possible to add something to the fluids that don't work well which you can 100% filter out afterwards, if needed, that could solve the problem?
Was thinking if was run in reverse could generate tidal power without turbines maybe
If you use MHD to pump seawater up hill then the inverse rule for Physics states seawater running downhill will create a current...
I hope Ricky doesn't get his heart broken by that room temperature super conductor. I heard very pessimistic comments on it.
Why not just transfer the kinetic energy from one fluid to another like a turbo does in an engine?
Definitely interested in more MHD coverage. It’s a fascinating technology.
I’m also interested in alternative conductor materials. A material as ductile as copper but with half the resistance for a similar cost would have a massive impact. If we can find one…
This was the technology used in the movie "The Hunt for Red October". You might be interested that a stream of water can be deflected by an electrostatic charge. I've often thought that this effect could be used to separate fresh water from salt water because only freshwater water molecules are attracted.
The hydrogen bubbles produced by the MHD if run through a fuel cell gives freshwater and energy...
Yes I'm aware of that it's a great piece of tech
Huh! Interesting… 🤔
I’ve always been fascinated by the separation of hydrogen from oxygen by using electricity. And when you burn the hydrogen and it mixes with oxygen we get polluted with water bahahaha
Imagine if we lived in a world that wasn’t motivated by greed? But Humans are truly retarded.
Watch the movie “Idiocracy” this is literally 💯 the way we are heading until we go extinct. Good riddance!!!
CZcamsrs should always pay homage to great sci-fi of the past!
Sean Connery: "I will take a Penis Mightier for $500 Alex"
"Red October" Anyone? Literally the fist thing I though of when I heard MHD. So Clancy got it right! ;-)
Wasn't it called a worm drive?
My first thought was Konpeki no Kantai/Deep Blue Fleet.
@@norme1850 A Caterpillar drive in Clancy's book.
I really hope you mention the fact that it only works if you have an ionic solution, and you need a LOT of dissolved ions to be able to make these even slightly efficient, even ocean water doesn't have enough to make this a very efficient pump.
It's specified
I've been fascinated with MHD since seeing The Hunt for Red October as a kid. I've seen action lab type experiments but no one ever went into depth about the shortcomings.
Acton Lab did.
I'm thoroughly excited by all the possible applications of MHD you've talked about here. I look forward to seeing a future of looking up to see plasma powered aircraft exhaust overhead, like it's total sci-fi. I highly recommend the @PlasmaChannel video on designing and testing a table-top scale MHD water thruster!
I'm also curious how an MHD generator would work at the end of a fusion reactor, being a source of superheated plasma.
A variant that I've seen used in several applications is MHD flow-meters. Small isolated electrodes inside the pipe, surrounded by a strong electromagnet. As the fluid flows, the electrodes can measure the small voltage generated and signal the velocity of the fluid. Using very sensitive electronics that don't require a lot of current, it works with only weakly conductive fluids. Once you have velocity and known pipe size, the volumetric flow rate is easy to calculate.
Ah yes isolated electrodes, the ground breaking technology that will help us reduce our energy consumption by 100% and save the planet!
membrane pumps are so cheap though and long life. plus bearings on regular pumps can last decades
@@archibibliothekarius2301 saying bros comment sounds made up?! 😂😊
separated electrodes pos neg actuslly will move water but so small amount of force
A flow meter can be turned into a generator anything that spins around and around...
No, I know that a sensor like that can work. Just don't isolate your electrodes if you actually want current flowing through them, otherwise they're pointless.
So like you said, separated is good because otherwise you'd have a short. But isolated is useless @@derrekvanee4567
The efficiency increase is very interesting. Further, the 'no moving parts' is intriguing. However, where pressure is high, the exit points of the fluid will eventually show wear and should for designed to ease maintenance and repair.
YES! Please do that in depth episode, would be fabulous...👍

I second this
Thank you for tying the recent super conductor with MHD. I instantly wondered about the connection. Please keep exploring all the possibilities such break throughs offer. Mankind (and me) need the hope.
Thank you for the video. I studied Physics as a major, and don't even hear of this phenomena before. Awesome!!!!
At 9:57, the efficiency formula onscreen, 1573/300 doesn't give the result 0.809.. It works only if you go "1 - 300/1573", which is, of course, a different formula. It's the same at 10:10, "1 - 300/3273" gives the right result.
🤓
Yep, I immediately noticed that error. I did know that the higher the temperature difference (or deltaT), the better the efficiency. Maybe the numbers were just shown for illustration purposes, but they really should not be written that way. You need to correct that formula. Otherwise, that was a very interesting video!
Now if that room temperature superconductive material is real (which I really doubt), that would make way for some crazy new technologies.
MHD propulsion video - yes please! Gets my vote. Thanks for all your videos Ricky, you take complex tech and make it fun and easy. You are making a difference and many of us love you and your team for it.
I am on board with this as long as there are regulations requiring that each power plant equipped with this technology have a 3 story portrait of Sean Connery as Marko Ramius on the outside.
super cool stuff! thank you for sharing this!
Unfortunately, it appears the room temp superconductors looks like it is going to be a bust. The search continues though
i concur
I think we'll get some research out of it and new understanding, will it change the world in short or medium term, not that much, if at all.
Don't need superconducting electromagnets for decent MHD drives anyways, so once it comes it can be an efficiency boost, until then there are solvable solutions.
As sea-water is conductive; would MHD generators be able to generate power anywhere in the coast? Yes an MHD propulsion video would be very cool to watch.
I'd be quite interested in an MHD propulsion system overview
Was this the “silent drive” utilized by an advanced tech Soviet military submarine in that movie 🎥 THE HUNT FOR RED OCTOBER
? 🧐 🧲 🌊
God that cold war crap🥱
Yes
I would like to have seen Montana ☹
Yes
Yes. And some of the dialogue indicates that, in the mid-Eighties (the period of the story and film), they would have been using liquid helium to cool superconductors.
"I have to find out what's wrong first! It could be a problem with the liquid helium or even the superconductors!" - Capt. 2nd Rank Melekhin, chief engineer
And of course in that era, if it had been well-enough developed, only a nuclear-powered ballistic-missile submarine could have afforded the power requirements. Then again, the very mission of a "boomer" requires that kind of silence, so I can well believe that the Soviet Navy of that era - or the Russian Navy today - would invest in that kind of project. Those Russians love to build 'em big, and even today they build the deepest-diving submarines in the oceans today.
I've seen no report - yet - that the Russians have built a boomer, or a fast-attack, with an MHD drive. But the Japanese never stopped experimenting with it, and I believe they built an experimental submarine.
I LOVE this channel. Its one of my top science related channels. Its a great place to get the basics of a complex new tech and still have details for the tech geeks.
you just made my day :) thank you for the kind words!
@@TwoBitDaVinci No, Thank you for this channel. I sub to many science channels and yours is the channel I share with non science types to share my love of science. Other channels are more technical or How-to style, and those are great but sometimes you need a channel that specializes explaining things in a way that focuses on the basic understanding of something, and why something is important vs getting nerdy. You channel makes science more accessible to everyone and not just engineering geeks and science lovers. You channel is one of the few channels me (science nerd) and my wife (non science nerd) can check out during breakfast and both enjoy the knowledge dump. Keep on with what you are doing. Thank you again!
It also sounds like it moves the upper limit for speed. Just as ion thrusters could accelerate spacecrafts to really high velocities higher than conventional engines. Could a long enough magnetic pump increase a fluid to super high velocities? Could a long enough one create a negative pressure such would "stretch" a liquid into a gas?
Thanks for sharing about the perticular technology 😊
Thanks! I really enjoyed this content!
Well done, nice video, thanks for sharing it with us :)
Would love to see a video on more MHD possibilities. Could you also talk about how close we are to it becoming commercially viable
About the propulsion part, spaceships use ion thrusters for some decades now, and this seems a similar technology. The problem with ion thrusters though is that they lack the force needed for takeoff, so this technology seems more suited for in atmosphere flight
I remember reading about this back in the 90s in a science magazine and was wondering why it wasn't in wide use.
Thunderf00t posted a critique of your LK-99 video. As expected, it wasn't very kind.
Of course he did ... what a hater
@@Disillusioned_one He also implied Nobel prize In Chemistry winner John B. Goodenough was a scammer. That is rather hateful is doubt there was any truth to it. That is before we delve into his Quran burning.
@roydouce9554 qualified maybe.... I'm just saying it's his whole thing to be a hater it's his niche
@@Disillusioned_one He also implied Nobel prize In Chemistry winner John B. Goodenough was a scammer. That is rather hateful is doubtful there was any truth to it. That is before we delve into his holy book burning or his hard on for that Musk fellow.
Always so informative your videos Dude 🙂🙏
From what I've seen about the new "Superconductor" is that it is likely not actually a superconductor, as no one has been able to reproduce the results yet
Thanks for your knowledge sharing
This technology is really cool the populsion system energy genartion are mindblowing and its very efficient also future proof coz it's less mechnical part... Full support 💪
Great vídeo, very interesting! ✌🏼🤓
I'd definitely watch a full video on planes using MHD!
Long time watcher, hardly a commentator...
Nice work can't wait for the next post
I've seen MHD pumps moving salt water in CZcams videos. One problem that I saw was extremely rapid corrosion of the electrodes. That might not be an issue in some applications, but it is something to be aware of.
I was about to say the intro video is fake, but you beat me to it.
It sounds like it would also avoid the cavitation problems that limit the speeds of propellors.
Technically it does not eliminate them as you could in therory try to pull in water faster than than it can move into your intake and cause cavitation bubbles but as a pratical mater you are correct. Youd have other material stress issues elsewhere if you could pump the water that fast let alone the power generation issues needed to pump that much current and that strong of a magnetic field on anything mobile.
would
Yeah, it's still subject to the same limits. It's not an issue with the prop or the magnet. It's a water issue
PLease make another episode about using MHD for rocket thrust, YES PLEASE!!! This is fascinating stuff!
More of this please.
Yes. MHD aircraft propulsion video is a must.
Thanks again for an informative video.
Yes please do a deep dive video into MHD.
the plasma channel just started doing experiments with this phenomena
Curiosity for fine details, to accurately tell the direction of the Lorentz Force, is the flow on the diagram at 2:10 of video going the opposite way it should? MHD sounds awesome, would love to hear more from you
Yup! This will be the future of propulsion! 👏😄✨ This is good news.
Full episode please!!
this is the most promising , please provide a follow through
Still waiting to see whether LK-99 pans out. So far, it's looking like it might be diamagnetic, but not superconducting. Other labs are yet to recreate it, although it appears that it may be a superconductor at liquid Nitrogen temperatures. I read yesterday that the lab that made it had some contamination issues, and that may be where the supercondicting effects are coming from. Too early to tell, but potentially a very exciting development.
Hello,
Sadly, the chances that the supraconductivity breaktrough is real are very low.
Many scientists and other specialized CZcamsr's (Sabine Hossenfelder or Anton Petrov) are scpetical, with very good arguments.
Anyway, you teached me how the MHD works, so now, we have to wait for room T° conductivity !
Thank You
MHD water pumps are NOT silent at all.
Inducing a current through the water produces cavitation, which in turn produces noise.
The higher the current, the more cavitation you get.
Presentation on point
I think that, the idea of using it in high heat doesn't hold, the reason is that, magnets don't like heat. That's why magnets work better when, they're cooled.
Hence the excitement about a room temperature superconductive material.
@@flightmaster999 room temperature is an absurdly far cry from 3000K
This was known for a very long time. Reason why it isn't used is the material will degrade so fast before it's even practical to use. Have you seen a sacrifical anode on boats? Yeah, that's what the anode in that supposed "bladeless propulsion" will happen.
Ok mhd ultra useful especially the power plants and the boat/ships
One wonders what might be done with a combination of MHD, Stirling engines and heat pumps with a bit of solar (heat and light collection) thrown in. Something else to put on the to-check-out list.
Love your video style. That fake magnetic pump video irritated me as well!
YES!! PLEASE make the episode.❤
The problem with many of these ideas require very high current at low voltage.
The low voltage is not a problem, but the high current is, as it causes high heat, even with low resistance, which is a major loss of power.
Another problem with high heat, rare earth magnets lose their magnetic properties when they warm up, so rare earth magnets would need a change to keep their magnetic properties when they are hot.
So, would you say that we're on a Hunt for the Room Temperature Superconductor? Doesn't have quite the same ring to it as "Hunt for the Red October" lol.
haha no it definitely doesnt' but i like it!
I'd like to see another episode with an elaboration on the topic.
HOW CAN WE GET THE 2 TECHNOLOGIES TO WORK TOGETHER ? AND HOW FAR ARE THEY DOWN THE LINE ? AS i WOULD LIKE TO USE THEM FOR WASTE TO ENERGY PLANT
It's the "caterpillar drive" from The Hunt for Red October
Is it possible to apply magnetohydrodynamics to Nicola Tesla's disc turbine? Or valve
Especially for industrial designs we may not need to wait for a true High Temperature Superconductors, the MIT ARC reactor is using a superconducting ribbon tape which is in current practical use with its fusion reactor design. Isn't it possible to adapt that tape for use in improving the efficiency of current fossil fuel based energy production methods and thus immediately address the level of CO2 production in those power plants, through efficiency gains and thus find that we need fewer new power plants? To be sure that may be true for many other large applications as well, such as, if it were integrated into the propulsion systems of ocean going cargo ships.
🎯 Key Takeaways for quick navigation:
00:00 🚀 Magnetohydrodynamics (MHD) is a real field of physics that can be used to create propulsion systems for ships and spacecraft, as well as pumps and electrical power generators.
01:06 🔬 MHD works by using electromagnetic induction and the Lorenz force to move fluids like water using magnetic fields and electric currents.
02:30 ⚙ MHD pumps have no moving parts, making them simple, compact, silent, and able to work at high temperatures. They are more efficient and require minimal maintenance.
03:13 🔌 MHD pumps are not practical for pools or home water systems due to flow instabilities, but they are ideal for industrial applications like pumping molten metals and coolants.
06:01 💡 MHD propulsion systems, which use fixed pumps to move objects through a fluid, have been built and can be used on boats and even in aerospace craft.
Now, everybody's gonna build a "Red October"... Just listen for magma displacements... ;-P
I would love to hear about those other MHD systems you mentioned. Thanks for the great video! :)
This actually fits these videos of suposive cloud UFO's. Maybe this technology is being tested currently or has been tested before. Ive seen a huge influx of these videos. When using a water vapor at a high temperature in a higher attitude could create clouds. Interesting
Wow the future is truly wild and amazing it seems.
hell ya giv of the episode :D
MHD propulsion sounds dope. That video would be interesting
Yes to the Ramjet episode
hi, ty for the video. i suppose youre refferring to LK99 when you talk about superconductors making advances. that would be great, even though the different testing groups, trying to replicate the korean discovery, come to results varying from positive, to maybe, to negative. hope they get it to work.
Would mhd propulsion eliminate cavitation? I would imagine that the navy would be VERY interested
Yes! Please make a video on MHD. Your description of it here lost me.
i maybe once saw a demo about dymagnetics: or anti magnet action. water tries move away from a magnet... a little bit. maybe worth looking at
I have heard about this. Its used in some applications.
Hmmm, was about to build an MHD. Now I'll see if I can do a plasma variant.
sounds like *hunt for red October electro hydro dynamic* 😂 LOL the buzz video uses 2 MOTs though talk about watts. bearings are efficient. hho is fun though
Petite question, si j'ai de bons souvenirs, lorsque l'on met des électrodes avec un courant dans une solution chargée n'allons-nous pas réaliser une électrolyse ? Et su c'est le cas les une des électrodes va s'user ? ou bien ai-je oublier quelque chose qui fait que les électrodes restent intactes ?
So there's a hope to conduct the reverse of magneto hydrodynamics? If so, this should be a game changer
LK-99 is not super conductor?
0:39 Lol! Well played.
Key phrase: Conductive Fluid. This works well for salt water, but not for fresh water. Thus, replacing motors, pumps and power generating in fresh water environments won't be a thing.
Pools using salt water chlorination, however, can used MHD!
With a room-temperature superconductor, cars wouldn't need batteries. The charge could be stored in the superconductor as current and siphoned off as need. Also regenerative braking is possible, making the cars even more efficient.
Cen you use those pomps in see water witout killing any fish who get to close? Dose it electricade whater geting out from pomp?
How long are these videos in "post"? It felt like the time between announcement and debunking was about 2 weeks, maybe 10 days?
There are also new surface coatings available and the physical design of the contact surface itself that can minimize friction - think higher efficiency and no wear!
Gotta love that hot source.
0:39: 🔬 Magnetohydrodynamics (MHD) is a real field of physics that can be used to create pumps, propulsion systems, and electrical power generators with no moving parts.

2:33-3:02: 💡 Advantages of magnetic pumps include simplicity, compactness, high temperature tolerance, reliability, efficiency, minimal maintenance, and potential for high power density.
Recap by Tammy AI
@7:57 I'd be _very_ interested in an episode covering magnetic pumps. I'd be specially looking for *_ship_* (or *_submarine_* ) propulsion application.
Can you imagine these as _thrusters_ on a *CyberTruck* as it fords a stream? 🤔🤓👍
I think this was part of the plot in The Hunt For Red October.
"The Hunt for Red October" 1990, comes to mind.
Yes same tech
Konpeki no Kantai/Deep Blue Fleet came to my mind.
Do you understand that the volume has to be huge to even get some noticeable propulsion ? There is a strict limit of voltage, because at high voltage the electrodes would quickly degrade and the losses due to ionization would skyrocket ? It wasn't that the idea didn't work, but it had very limited efficiency for high output applications.
"Give me a ping, Vasili. One ping only, please."
Yes. Please make that episode.
