No, my Explorer design doesn't use on board fuel for accell out of the sol
system, or return decel. A bigger problem Is I forgot the 2e7 exaust
velocity was for a He3 system which obviously isn't very feasable for 17
years of onboard storage. (Liquid helium is incredibly good at geting out of
sealed containers.) I havent bothered to try to figure out the numbers for
Li6 fueled system yet. But I remembered they sounded bad.

If it would take over 17 years to get to, I'ld say its about as far as we'ld
