Group, I really would like to see how they plan to get a 1800 pound aircraft 
to climb at 5000 ft/min with only 450 HP! I would like to know which magic 
physics book they used for those calcs! They list the fuel capacity at 50 
gallons. When they convert to turbine the 1 hr max flight time would be 
somewhat limiting. Is it real or is it Moller?

Doing the physics; 1800 pounds at 5000 ft per min 83.4 FPS is 1800 times 83.4 FPS is 
150,000 ft pounds per second. Dividing by 550 ft lb/sec or one HP  gives us  272 HP 
not counting drag and prop efficiency. Assuming the rotor in the duct is 80% efficient 
that means 340 HP out of the engine not counting drag. Doing the same sorts of 
calculations on the Moller sky car also makes it look possible.

The devil is in the details of the control system as the Wright brothers, Moller and 
AMV will find out if it ever gets that far.
