    So we can start building the thing then? or are we waiting for appropriate tech to be developed?

    Just around the bend.
    The answer to your question is in the name of the thread.

    This is a good site for options: http://www.projectrho.com/public_html/rocket/enginelist.php

    Smoother than the nuclear pulse orion concept is the Nuclear Salt Water Rocket

    Its fringe-worthy--but look how well it does with a 90% solution on this graph:

    Best yet: The advantage of NSWR is that this is the only known propulsion system that combines high exhaust velocity with high thrust.

    Thrust 13,000,000 newtons with 4,700,000 m/s exhaust velocity--a one two punch!

    NTR DUMBO looks more do-able

    This would provide 3,500,000 newtons thrust

    Now imagine you use that in place of a Centaur upper stage, and have AIMSTAR as a payload:

    This would provide 598,000 m/s exhaust velocity. This alone would allow a trip to 10,000 AU in 50 years. Couple this with DUMBO NTR to get most of its useful life extra-solar--NOW you have a souped up New Horizons.
