I agree. The first article made my scam antennae twitch with
those "frictionless bearings". Yeah, right - nanokelvin
superfluid lubrication or whatever that can be "repaired by a
local car mechanic"?  I think not!

This article somewhat redeems the claim in the form of "near-
frictionless bearings". OK. But as you say without even a video
of the small scale concept-demonstrator no one would be wise to
invest one yen, dollar, pound or sheckel. The principle is
obscure.

I'd never heard of Voith Schneider but like you I have trouble
seeing how this contraption of carbon fibre plough shares is
supposed to provide lift and 360 degree 3-D thrust vectoring in
near silence. I know there's a lot of computer control involved,
but basically, how can something at once so technically "crude"
and so operationally versatile not long ago have been exploited?

Or... has it?
