alt Hacker NewsWell... If the launch cost is low enough you can just pack a radiator large enough. Good thing this might drive the development of a wider Starship and Ultraheavy booster (or a Superheavy-Heavy where three Superheavy rockets boost a bigger, heavier Starship). Eventually we can get to the Comicallyheavy booster.
Perhaps, but I don't see the costs getting anywhere near being worth it. You'd need a space elevator or to manufacture the sinks IN SPAA— er, in space. The latter is theoretically possible but still extremely remote, the former still requires unobtanium.
