On the other, more important hand, at firt view, this looks feasible to me (taking into account who published it)

I do wonder about the "little noise" claim, though. That fan a few meters in front of you that compresses air so that you can float on it will not be noise-free. I also think those tubes could start resonating at times.

Finally: only about a thousand passengers per hour or, alternatively, going at close to the speed of sound, on guaranteed collision course, with 30s intervals?
