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?
