So apparently the patent is for a single pilot turbo'd twin diesel estimating 50,000 ft cruise altitude. Of note is the prop is driven by a torque converter which is quite an interesting way to drive it - it will cut down on vibration considerably.

The patent application mentions competing with the airlines on a point to point type service vs hub-spoke and includes some rants against the airlines. Kinda weird. Seems like the bulk of the patent is for the wing itself.

The aircraft cabin may be approximately 74 inches high and include an approximately 78 inch width having a minimum 50 inch seat pitch. The aircraft has a service ceiling of approximately 65,000 feet, and a normal cruise speed of between approximately 460 to approximately 510 mph, with a specific fuel consumption of approximately 30 to approximately 42 mpg depending on cruise speed and altitude. Landing stall speed is approximately 70 mph, takeoff and landing speeds are approximately 90 mph, and runway requirements are approximately 3000 ft.

And create lots of heat and efficiency loss.

So, it wasn't fake after all. The FAA Aircraft Registry page for N818WM shows a reciprocating engine.
It says reciprocating, but it doesn't specify the fuel. ;)

With the 2nd photo of the engine bay open, and the large amount of thermal insulation on those intake plenums (and what looks to be a pressure vessel on the firewall), all signs point to cryogenic liquid hydrogen IMHO. :)

Before the SR22 and SF50 there technically was a VK30

I've sat in one. Cool airplanes!

A pill with wings? They should paint it burnt orange and have Advil (circle "R") sponsor it.
In all seriousness I would guess the "ultralight Rotax prop thingy" is just there for powerplant or taxi tests. Although anything much bigger would probably result in a prop/tail strike at the same time :ooh:

The patent diagrams look like they're trying to use the multiple turbocharged exhaust to produce additional thrust. Kind of like a prop/turbo jet combo. Neat idea! If it works...
