   I belive that the rocket-propulsion schemes (throwing a ball,
blowing a balloon) are all much much less efficient than something
that involves taking advantage of pushing off of the air itself.
(i.e., heavier than air flight with wings and propellors can be done
with a lot less power than a plain reaction rocket-engine)
 The suggestion of swim fins seems like about the best idea. Maybe in
a pinch you could grasp your shirt in two hands and wave it back and
forth the the tail of a fish. (In sailing, if you are becalmed, and
you pump your tiller back and forth, you get some forward motion)
