Michael Johnson June 21, 2011 03:52 PM would love to see a video of this! Todd Dunning June 21, 2011 04:28 PM Wow. Possibly a very big Wow. Windmaster Hiroaki June 21, 2011 04:30 PM Sounds pretty revolutionary... hopefully we\'ll get to see videos of this thing actually flying soon... Mindbreaker June 21, 2011 08:53 PM My first thought was that it was a vastly improved ducted relative of the spinning wing (1930). But from the info it seems like Centrifugal fans. It would be nice to have more details on the principles of flight involved. \"contra-rotating cylindrical turbines\" suggests it is more like the later. Are we talking turbos like in cars? Seems like superchargers move more air. The 2,200 RPM sounds more like a fan and less obnoxious sounding than a turbo/supercharger. The article also does not say where the air intake is. That seems like a major omission to me. Oh well, I guess we will hear more about it.If it really is efficient, powerful, maneuverable, and easy to control, it might work in some sort of \"jetpack\" form. There was the scaling comment though...so maybe not.The actual numbers provided do not sound heavy lifting yet. Everything starts small. I hope it is the real deal...it looks very interesting.I second the request for a video! Mindbreaker June 21, 2011 09:07 PM Someone on another site suggested it is a version of a Voith Schneider Propeller. That seems to fit. Facebook User June 21, 2011 09:44 PM Sounds great, but I\'ll believe it when I see it. I\'ve been burnt enough times by articles on gizmag making something sound like magic, only to come back the next week and debunk the myth.Anyone remember that new dynamic ratio gearbox that was supposed to radically change the automotive industry forever? No? That\'s because it turned out to be over-hyped crap. Todd Dunning June 21, 2011 10:04 PM Excellent points Mindbreaker. And in retrospect, exciting as this is it lacks the helicopter\'s ability to autorotate and glide from engine failure. Not that it should not still be persued however. Voith Schneider indeed. Facebook User June 21, 2011 10:38 PM This would be how \'alien\' space ships move about wouldnt it ??? Terry Penrose June 21, 2011 11:51 PM Amost silent? I find that hard to believe. Anyone knows that air moving at high velocities and volumes make shitloads of noise regardless of how its created. Nontheless it sounds like something worth following to see how it developes. Alan Hutcheson June 21, 2011 11:52 PM Waiting to see a video, but the technology sounds incredible.
