  Nah, that's COMPLETELY different than actually using megaton-range nukes
as propellant. It's never been shown to really produce more energy than it
uses to run.

  I remember that. But beyond the basic idea nobody's actually come up
with a way to mag-confine particles and use them as thrust. Obviously this
system can't block hard X-rays and other gamma radiation, nor can it
prevent neutron embrittlement and irradiation. Hence you can never use it
in a manned system.
  And remember that the power of a pellet is orders of magnitude less than
that of a massive nuclear bomb (PLUTO project, recently declassified).

  It can _never_ be producing 'just charged particles', what kind of
nuclear reaction would that be? After all, we're not fusing "Pladough"
  And even if you have a magnetic field, you'll have a tremendous amount
of radiation going up and DOWN the field, i.e., a big thrust 'plume' out
the rear of your ship, and an equally powerful plume of radiation
screaming right down the middle of your ship! You better have something
tougher than a sheet of lead there to block it. (GRIN)

  Hey, I'm not the Probe for no reason!
