So why use little tiny blades.	Maybe auxilliary jets?	Compressed gas?
Null-G packs.

Too late, already been used. :)  The Navy has used them and I believe
they were used in Viet Nam.

One other thing I still am not sure I believe is part of the vector
of the GEV pushing it down hill.  If the skirts follow the terrain
and the GEV stays level it appears to me as if the GEV would experience
the same (or maybe even less) downhill force than the equivalent
ground vehicle.  The fan isn't blowing at the ground, the fan is forcing
air into the plenum, your fans could be on the side of the GEV aimed 
toward the center hand the vehicle would still hover.

However, I am encountering another problem that could be insurmountable.
GEV over water, when the pressure required to hover (say 10psi) exceeds
the mass of the water underneath (not very well put, but I hope it gets
the idea across) wouldn't the vehicle sink?  Anyone know at what
pressure
this would occur.

story?)
