Cool, somebody's building something real! <G>
I must confess, I really enjoyed the page, but I didn't
look at the MOC so much as reading all the cool text. I
eventually ended up hopping to some other sites to learn
about the Heliosphere :]

Okay I have 2 questions, probably related. The first is
why does this drive only work well beyond the heliopause?
The other is how does the drive actually work? I've heard
the concept before but never really dissected it until now.
What is the mechanism that tranfers energy from the explosion
to the ship to move it? I'm assuming that the nuclear
eplosion produces tons of energy but very little in the
way of matter (gases, etc). With no matter to transfer
momentum to the ship, what makes it move? Granted the
explosion will radiate energy through vacuum to the ship
(e.g., heat), but that would just make it hotter, not make
it move. What am I missing here?
Thanx,
KDJ
