Fusion Rockets

On fusion rockets:

I tried using George's modification for fuel consumption.  George multiplied
fuel consumption by a factor of 40000.  Thus the 200,000 disp ton tanker I was
using which only had an acceleration of 1G could fire the engines for 41
minutes.  Instead of the 3+ years I had originally planned on.

Ok, that may be correct from a engineering and physical reality point of view,
but it makes them totally useless when compared to grav.  Well, I think that
to make the game fun, your fusion rockets should allow a higher acceleration,
but more fuel needed.  THat sounds like a reasonable compromise.  But George's
fuel consumption outlaws their use completely.  (sigh)

As much as I like to see things realistic, they should be usable too.  (I also
prefer the notion of somthing I can understand (fusion rocket) as opposed to
something I can't (gravitic propulsion).
