I can't see any real advantage or we'd certainly have seen them in more places than ATVs.

I printed the picture and took the height of the vanes from 3 different locations. The walls of the passenger cabin are about 3 feet high before it meets up with the curved roof. Even more troubling is the idea that this pipedream is gonna fly at 700 mph. They don't give a cruising altitude, but at sea level Mach 1 is 769 mph and it goes down the higher you go (something like 660 mph at 11000 meters or commercial jet cruising altitude). I'd like to hear the sonic boom when this baby busts the sound barrier! Neil, you are mostly right; the scale is way off.

The screw vanes are three feet high? looks more like 15 feet high to me, otherwise the passenger cabin is only 2 feet tall. Don't know why I'm worrying about details on it, I suspect the 700 mph airship won't be plying the skies any time soon Am I just reading it wrong (that’s been known to happen!), or is the scale way off on the drawing?
