Problem is the main drag is on the diver, not the scooter, this would give
very small improvements not worth the trouble.

One of the theories is that the Kursk was trying out the new liquid fueled
high
speed torpedos when it blew up.  Of interest is that the Russians are
cutting
the front end off the sub and leaving it behind.  If they really wanted to
find
out what happened (ie. didn't know already), they would be itching to get at
the bow section.
Since the new propulsion technique involves generating a bubble of gas
around
the torpedo/vehicle/whatever and then taking advantage of the reduced drag
to
speed up to near (or above) the speed of sound underwater, it seems to me
that
if the same thing could be done for a scooter, the endurance improvement
would
be dramatic since you really don't want to go much faster than scooters go
now.
 Obviously you need a gas source, the Russians just proved why using the
exhaust
from a Walter engine is dangerous:)  Perhaps running the whole system on
compressed
air- gas spins a turbine which is then exhausted out the front of the
scooter
to create the bubble. The turbine of course spins the prop.  The engineering
is way out of my league, so that's why I brought it up here.  There are a
number
of bright guys that can poke holes in the concept.
