a 5 place airplane capable of jet like performance using a 200HP diesel engine using 5GPH fuel. That's right, 200+ MPH at 25,000+ feet getting 40MPG
So which is it?

Theory goes that this creates a huge venturi area between the wings creating way more lift than normally possible for the given sized wing, and, it eliminates the trailing vortex that creates huge amounts of drag, so induced drag is remarkably low.
I suspect a lot of their no-vortex claims come from the vertical stabilizers. Maybe some of the concerns expressed could be alleviated by a small canard. I'd make the inner vertical stabilizers into a full ring wing.
