 I have an essay on this in the current issue of The New Atlantis. It should be available on line soon.

Perzackly. Who needs fancy-shmancy custom rad-hard featherweight liquid-cooled vacuum-rated electronics when you can buy standard 19" rack mount packages, put 'em in a steel pressure hull an inch thick with a polyethylene liner to catch the secondaries, blow the cooling fans through a flat plate heat exchanger, and call it good?

We're talking _literal_ battleship construction.

    and mass.  To date, every payload has to watch every kg, every cubic
    cm.  What happens when you can throw another cubic meter, lift
    another
    100kg mass at a problem?  How much time and money will be saved
    when you
    don't have to sweat that last one percent of your lift budget?

    As Henry pointed out in an earlier thread about dealing with
    atmospheric
    & water leaks, with reliable lift schedules, just lift enough to
    replenish for several cycles while fixing the problem.  What
    changes in
    your planning when that supply run can be 50 or 100 tons of air or
    water?
