What advantage would this have over a rotary Hallbach array?

Maybe I'm missing something but this just seems to be a guy playing with magnets? In the "Demonstration of Ion Propulsion" video, he shows how the magnet "shoots" through the ring, but it's just the release of potential energy from forcing the opposing poles together in the first place. It's like those "permanent magnet rail guns" people post on YouTube. I don't see what's novel about it.

beneath the fancy graphics there's zero explanation of how these are manufactured, how they're constructed, or the magnetic field patterns. No actual deployments or demonstrated applications, just graphics. It's a 3-person company that "expects to begin testing of this exciting new technology early in the 2nd quarter of 2023".

Howard JOHNSON, Permanent Magnet Motor http://www.rexresearch.com/johnson/1johnson.htm - is that similar ?

( https://patents.google.com/patent/US4877983A/en expired 2006, https://www.freepatentsonline.com/4877983.html )

Edit: https://www.paranetics.com/electric-motors - there is more details. And parametric motor https://patents.google.com/patent/JPH04344155A/en is more similar.

(and magnetic experiments https://www.youtube.com/watch?v=UZaRMt6xhoE explains a lot nicely)

Don't talk about it, be about it.

I migh sound negative but when I was reading through this website it looked a bit like free energy scams to me, "stick a rod into the ground and voila, bulb is lit". drawings of magnets with two poles adjecent to the same pole- when I was attending physics course our proffesor told us that magnet would rearrange so there would be 2 poles if we tried tricks like this.. I'd like to see the 'how it's built' before I can attempt to get rid of my scepticism..

I'm not sure what they want to achieve with that. The logo looks like they invented magnetic monopoles, but otherwise it's just a lot of blabla.

Investor trap?

I misread that as "a magnetic fluid orientation" and it made me wonder: could a torus of liquid or something like that be induced with a spinning magnetic field to replace mechanical motors for electricity generation?

the idea is simple enough, use both poles of permanent magnets, unlike other motors that use only one side while alternating the polarity of the fixed magnets. Watch the little slow motion video, it is either a masterfull slight of hand, or evidence. the magic I believ is in harnessing modern compute and power control hardware to achive something that was long ago dismissed as wishfull thinking

Did I miss the memo where we repealed ∇·B = 0?

It reminds me of a cylindrical Hallbach array that has been split in two.
