I just read the book this year. The book Red October just uses internal propellers for it's caterpillar drive. Even then, it wasn't prefectly stealthy.
"When I was twelve, I helped my daddy build a bomb shelter in our basement because some fool parked a dozen warheads 90 miles of the coast of Florida. This thing could park a couple of hundred warheads off Washington and New York and no one would know anything about it until it was all over"
Gee what's with the hate towards Yamato and Bismarck on the history nerd's circles in the recent years? I swear this never happened before, regardless of what they "accomplished" (since they're machines, it's not them who accomplish stuff but their crews), they're still magnificent pieces of machinery and human ingenious that not everyone was able to achieve and deserve respect for it.
This technology, funny enough, could also be used for flight or space flight, the possibilities of MHD Propulsion is limitless that is if we can solve the technologies' hurdles like the corrosion issues and such but it is possible
An engine that drastically alters the magnetic field in its surroundings would not work on a submarine. Looking for disturbances in earths magnetic field is one of the ways to find a sub already. A mhd would be like turning the ligjts on in a dark room.
An interesting experiment for sure but while it did prove magnetohyrodynamic propulsion was possible, it confirmed that it was not practical in the slightest. Seawater is a very poor conductor requiring a very strong magnetic fried to achieve usable efficiencies. In the paper you reference they cited an efficiency of "less that 2%" at the intended 4 teslas(typical props are ~70%). Even if 20+ tesla magnetic fields were trivial to produce the difficulties of pushing thousands of amps through seawater will remain a major hurdle to the use of MHDs in place of props. There could certainly be niche uses but ordinary commercial ships will be using props for a long long time to come.
I disagree, I think it proves that it is feasible we just need further advancements in technology to make it a practical option. The benefits for submarines in particular will likely mean that it will eventually be adopted for at least some applications
Has nobody really revisited this concept since "high temperature" ceramic superconductors were invented? I mean, there's always @PlasmaChannel: ruclips.net/video/WgAIPOSc4TA/видео.html
It seems like the level of both complexity and preparation needed for something like this to be effective would be on the same level as a hyperdrive in most sifi stories
6:16 I'm pretty sure that -273 C isn't correct. That's 0.15 degrees C from absolute 0 (0 Kelvin), which is impossible to reach. Liquid Helium has a temperature of 4 K so you wouldn't get close to 0 K with that...
I don't believe so, the helium was used to cool the magnets, which were not in direct contact with the water. In the diagram at 11:55 it appears that the shield plate and vacuum vessel also exists between the helium vessel and sea water duct.
A TON of armchair quarterback speculation here, but it was said that that the hull was aluminum for electrical/non ferrous properties, I'm guessing that they went with aluminum over fiberglass as it would need a massive heatsink to disapate all that heat from that type of drive. Would also be difficult to use in a military deployment as the ship would just glow on the water from IR. Any thoughts author? Did you find anything during your research regarding heat production?
Isn't this the academic equivalent of a nigeria letter? Just give me even more money, and I'll revolutionise marine propulsion, even though the technology is inherently extremely inefficient and requires ridiculous amounts of maintenance from simple electrolytic erosion of the electrodes
It's more similar to the early stages of things like internal combustion or flight. While our current technology isn't really advanced enough to make it practical the Yamato-1 proved that it does indeed work if we can find solutions for the limitations
@@ConeOfArc It's an inherent limitation with how the technology works, the same way you can't make a bouncing ball bounce higher than the height from which it was dropped without adding energy. Outside of a few niche uses such as pumps for extremely toxic fluids, it is just a gimmick. We get these projects all the time at universities. The ones that make you say 'that's not how any of this works'. Usually, the board of professional responsibility 86 those projects early on because the university doesn't want to become figuratively radioactive and lose supporters that way. But every once in a while something slips through the cracks, and you get some bloke claiming he can make mice immortal using magnets.
A coffee percolator doesn't need a srew or a boat load of useless nerd dollars to prove the obvious. I assume the designers of the emergency circulation cycles of nuclear subs eventually realised such.
Pretty sure the battleship was name after Admiral Yamato, you know the architecht of Japanese success in world war 2? Guy so important that Americans had to cock up a complicated plan to murder him to have a chance to win the war? Henche, this Yamato here too, named after the guy.
The Admiral's name was Yamamoto. The Japanese tended to name their ships after things in nature, winds, mountains, or the super-natural, dragons, spirits, etc. Not people.

They changed it in the movie to be a MHD although they still refer to it as a caterpillar drive as you see in the clip
"To the Batboat!"
Yeah... Wayne Industries probably has one of these somewhere.😆

First time I've heard of this ship, technology as reality. Very interesting, thank you for the video.
I wouldn't name something after a ship that basically accomplished nothing except becoming a giant home for deep sea fish.
Travelling all the way to Iscandar and back was no small accomplishment!
At least it wasn't intentionally beached on a shore to be a shore battery. She went down fighting like her younger sister, Musashi
The term Cannon Fodder is applied to many new technologies 😊

The historical pendulum. Praise, backlash, backlash to the backlash, and then it eventually calms down.
Wave Motion Engine when???
Wait 174 years

Please make a video about the Katie Mk-33 nuclear artillery shells that were to be used on the battleships Iowa and Wisconsin

I saw this when my group did a stopover at the marine museum in Kobe, but I was more interested in lunch, which was Kobe beef, of course.

This is so cool
Was there any issue of the liquid helium freezing the seawater in the drive ducts?
I don't believe so, the helium was used to cool the magnets, which were not in direct contact with the water. In the diagram at 11:55 it appears that the shield plate and vacuum vessel also exists between the helium vessel and sea water duct.
What was the energy efficiency?
Yo, Japanese government come on man you could’ve preserved at least something…. Smh. It’s a shame that it was scrapped
New war thunder premium?
No, it's a research/civilian use vessel, not military
Sad
Its a cool movie (the hunt for the red October)

Maybe, but aluminium also alumagnetic, which basically means non-ferromagnetic (ElectroBOOM patented)
@LastGoatKnight I believe the term is dia-magnetic. Much like copper.

The battleship was named after the old Yamato Province of Japan, which is also a name for Japan itself.
The Admiral's name was Yamamoto. The Japanese tended to name their ships after things in nature, winds, mountains, or the super-natural, dragons, spirits, etc. Not people.
