Things like this will never be allowed to be mainstream. I mean people generally cannot as a whole manage a 2 dimensional field of travel. Do you really think that society can handle 3 dimensional travel?
Beyond that, when someone runs out of fuel, they will not simply coast to a stop, they will fall to their death.
As fun as i think that this or personal aircraft would be, We are just too stupid as a society, and it would be impossible to make this safe enough for the masses.

Why not use a rotary instead of piston engine? Much more efficient in terms of power/weight.

Rotaries can be charge cooled as opposed to oil cooled, thus removing the oil consumption issues (I get its a joke, but still). Rotary efficiency issues come into play at lower power levels (I.e. cruising along the interstate) but are almost equal to piston engines at full throttle. In an application where large amounts of thrust are constantly required the efficiency issue isn't really a big deal. Plus, less weight means less thrust needed.

[QUOTE=tarheel91,Oct 4 2010, 09:26 AM] A rotary is typically bulletproof (moreso than a piston engine) if maintained correctly.
