[@Maungateitei]

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.! 😝

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.

[@PeteTheL337]

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?

If you use MHD to pump seawater up hill then the inverse rule for Physics states seawater running downhill will create a current...

[@joseq8466]

Why not just transfer the kinetic energy from one fluid to another like a turbo does in an engine?

[@russadams3008]

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.

[@steveo5295]

The hydrogen bubbles produced by the MHD if run through a fuel cell gives freshwater and energy...

[@andrewreynolds912]

Yes I'm aware of that it's a great piece of tech

[@zjedinite]

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.

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.

[@michaelransom5841]

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.

[@MrRickyw01]

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.

[@franco_is]

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.

[@mikefochtman7164]

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.

[@archibibliothekarius2301]

Ah yes isolated electrodes, the ground breaking technology that will help us reduce our energy consumption by 100% and save the planet!

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

Thank you for the video. I studied Physics as a major, and don't even hear of this phenomena before. Awesome!!!!

[@Sylfa]

3:12 - There's been a *slew* of research groups looking into it, all debunking it: “With a great deal of sadness, we now believe that the game is over. LK99 is NOT a superconductor, not even at room temperatures (or at very low temperatures). It is a very highly resistive poor quality material. Period. No point in fighting with the truth,” the University of Maryland’s Condensed Matter Theory Center (CMTC) posted on August 7th. This is *why* you shouldn't look at the initial first study/paper and then start repeating their claims. *Especially* if they are so fantastical as "room-temperature, atmospheric-pressure superconductor."

[@Sylfa]

Oh look, Condensed Matter Theory Center posted something rather pertinent on 26th of July: NEWS FLASH: we contacted several CMTC alumni in Korea who are faculty members at the top Korean universities, and NONE has ever heard of this group from Quantum Energy Research Center, and they are as stumped about these claims as we are. Probably not a good sign.

[@bytemark6508]

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.

[@bagochips1208]

🤓

[@flightmaster999]

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.

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?

[@katiegreene3960]

[@DeclarationsOfTruth]

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.

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

It sounds like it would also avoid the cavitation problems that limit the speeds of propellors.

[@merendell]

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.

It WAS briefly showcased in the August 1990 issue of popular mechanics as the promising technology to enable 100-knot freighters, but still very little coverage for decades following Yamato-1, which really was hijacked to showcase portable marine cryogenic systems. They didn't get the funding they needed or the flexibility to design the vessel they originally envisioned.

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.

[@backyard4465]

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.
