How did this ship use magnets to move in water? | Skill-Lync 

We hope you have an amazing experience & learn lots of exciting stuff! :)

The generated magnetic fields can be detected by foes, I'm sure he said that in the end of the video.

@@theexam7394 one word. DENSE METAL COVERING

@@dae1925 Doesn't work. Magnetic anomaly detectors can pick up a submarine just by the presence of a large metal tube in the ocean alone due to the infinitesimally small effect it has on the earth's magnetic field. Can you imagine how easy it is for them to pick up on a submarine with actual superconducting magnets on board? It would be child's play.

Except on Red October!

Big brain time son

But they retired the Typhoon class subs

I am. He was the best author.

I am here after seeing The Hunt for Red October for the tenth time or so... XD

Yup, you would have been so much fun around the Wright Brothers, Edison, or a ton of others... Killjoy...

@@superbmediacontentcreator No, actually ur comparison is totally wrong. We are talking about what you can do with the knowledge and technology of the contemporary age. People you mentioned were ahead for their historical moment. This boat is a good experiment, but it's the only good thing you can argue about.

@@Nightrapture Your comment just reinforces my point... thanks...

Actually Yamato One had a speed of 27 knots, which is rather good for a shit, it is a tiny bit slower than american destroyers

@@Nightrapture The boat WAS an experiment. Which why that other guy laughed at you. It was a technology testbed, not a commercially mature product. All new designs start somewhere. The fascination with MHD's is largely a military one. They have no moving parts, so they generate no propeller noise. As the man explained at the end, the giant magnetic field gave them away to aircraft with a magnetic anomaly detector. It's interesting tech to play with but it's unlike any practical applications will be found.
