Well, it's claimed to be silent, so probably not. But, I went straight to whales as well, this could be a great option for a quiet whale watching boat.
For a second… for a second, I thought I heard… Singing.
wondering if it could replace the propeller on self-propelled hydrofoil surfboards
Since we’re already this deep into science-fiction, could we superheat air and then run the plasma through this in order to create a land or air vehicle with no moving parts?

I agree that an innovation of this magnitude would have a huge impact on naval propulsion if it were publicly available though I’d imagine the tech would be locked down to a ridiculous level. It’s likely destined to only appear in nuclear submarines.
Yeah, no. Once it's known that it's possible to achieve, some enterprising company will quickly replicate it. Unless, of course, it needs unobtainable levels of power.
Also, about the need for a coolant, well, the fixed costs for it are on the order of a few $100/m on most cities nowadays. If people start to use lots of it, the fixed costs will fall to zero. (The variable cost isn't high, but it also doesn't dictate the boat size.)
> If power and efficiency issues are resolved, My gut feel is that this is a pretty grossly inefficient system by nature. Inducing current in seawater just to give magnetic traction something to push off against seems semi absurd.
On the case of this, my gut feeling tells me that making the magnet really, really big will do it.

Do you have a more credible citation? That guy on YouTube seems to be the most common source for this claim and he gets paid for clicks. More mainstream sources don’t seem to think Russia has any particular edge here.
He worked on MHD, he knows what he is talking about, he also worked closely with Russian scientists, not something mainstream media would cover, specially nowadays http://www.savoir-sans-frontieres.com/JPP/telechargeables/En... Anything that'd destabilize a country is generally not publicized by the press, unless it benefits you He started a non-profit, distribute all of his work for free, and pays for translations i…

Bay area waters were (are?) used as a naval magnetic silencing range. Most navy ships have degaussing coils that calibrate with magnetosphere https://www.dropbox.com/s/qansmciigewti4n/IMG_2957.JPG?dl=0
Degaussing in a bay is much different from trying to cancel out 20T(!!!) of EM signature
EDIT: on second thought, if you can build a device to generate 20T you can probably build a contraption to cancel it out as well. It would most likely boil down to the economics or the scale of the contraption required.
I wonder if it sounds like whales humping or a seismic anomaly…
