Reminds me of that Steorn Orbo scam a bunch of years back. I recall it was a... broadly similar thing, switched reluctance, with the claim that the energy used by the electromagnets is independent of load, and approaches zero (a casually plausible claim, but easily disproved).
In this case, I wonder what they're doing about core loss. At, apparently 20kHz, that's a lot of switching for one, and implies ferrite or other high frequency core materials. Which implies torque is even lower (low Bsat), on top of already being low due to the limitations of switched reluctance in the first place. Hard to say, there's very, very little technical detail in the video.
So, at this point I would have to agree, it's an, apparently, so far, exquisite grift, just fancy enough to hook some big names, presumably actually giving out big bucks.
