Way back, I got a chance to play with some prototype "ATV - like" consumer
ground effect machines. They looked like a cross between a Vespa motor
scooter and an ice rink resurfacing machine. We unloaded them in a big,
empty parking lot and fired them up.

The first thing you learn about ground effect machines is that they stir up
a LOT of dust - even where you didn't expect there would be any dust.

The second thing is that they will almost uncontrollably slide downhill. In
this case, until they got to the storm drain gratings in the corner of the
parking lot where they grounded themselves - there's no ground effect above
a grating. We then faced the problem of an 800 pound machine with no wheels
firmly stuck on a storm drain grate. Fortunately, the truck that delivered
them had a wrecker crane - possibly due to the developers previous
experiences with storm drain grates.

We decided that dry land was possibly not their native environment so we
tried them over water since water is 'mostly' level.

The first thing you learn about ground effect machines over water is that
they kick up a LOT of spray - enough to thoroughly soak the driver. You
need goggles to keep the spray out of your eyes but spray covered goggles
are hard to see through.

The second thing you eventually discover is that when the engine quits over
water the thing sinks FAST. Fortunately, the developer had a water recovery
skiff with a crane and plenty of drying out stuff - possibly due to previous
experiences with over water engine failures.

Maybe this is why you don't see a lot of consumer ground effect ATV's.

GROUND-EFFECT VEHICLE PRODUCTION LAUNCHED
Moller International has completed tooling for its M200G volantor, a
small,
"Jetson-like" two-passenger vehicle designed to take-off and land
vertically. The M200G is saucer-shaped, about the size of a small
automobile, and is intended for operation continuously about 10 feet
above
ground level. "It's the ultimate off-road vehicle, able to travel over
any
surface," claimed Dr. Paul Moller, CEO. He further claimed the M200G
could
speed up to 50 mph over a variety of terrain because the electronics keep
the craft stabilized at no more than 10 feet altitude, where extra lift
is
obtained from operating near the ground. For more information, visit
www.Moller.com.

I'll bet it's a real thrill going over hills, especially on the downhill
side.
