  • Commented on Why I barely read SF these days
    Some of this stuff is why I rather bounced off the Expanse books. Sheer momentum kept me going to the end of volume 6, but I don't think I'll persist. There's a veneer of scale, but the writers mess about...
  • Commented on New Book Week!
    Some societies, yes. But so what? (a) That doesn't seem to be the sense of that paragraph. (b) The Commonwealth does not appear to be such a society....
  • Commented on New Book Week!
    Something nobody else has mentioned: page 265: "even before the official mourning period is over. Which I, and my wife, will be expected to attend---if you are still here, perhaps you could accompany us?" Does one "attend" a mourning period?...
  • Commented on Crying fire in a crowded theatre for pleasure and profit
    People commenting on fire safety in UK high-rise, please note: the fire brigade does know how to fight high-rise fires. I heard one fire brigade spokesperson say that they deal with two or three fires every week in residential high-rise...
  • Commented on What else can you do with a Big Dumb Booster?
    In space, procure a large, shallow dish, like a quiche pan several meters in diameter. Affix a very low trust motor to the bottom and start the dish rotating slowly. Pour thermosetting/ photosetting or other such material into the dish,...
  • Commented on What else can you do with a Big Dumb Booster?
    The reason I harp on about the target cost to orbit is that if they do hit $10k/ton for the fully reusable stack, or even $100k/ton, rather than the $400k/ton number ($200M for 500 tons: it's unclear to me where...
  • Commented on What else can you do with a Big Dumb Booster?
    Target cost *per booster launch* is under $2M, including amortization, propellant, launch services, and maintenance. The keyword there is "target". First couple of dozen launches? Not so much. Yes, but you wrote: the cost per launch for an ITS stack...
  • Commented on What else can you do with a Big Dumb Booster?
    (The whole presentation was just vapourware, of course, apart from the shots of the BFS tank and the Raptor test-fire. Which on their own were plenty exciting enough)....
  • Commented on What else can you do with a Big Dumb Booster?
    Yep: the cost per launch for an ITS stack is targeting around $200M (but more like $1Bn for the first couple -- they won't be flying again, they'll be torn down for post-mortem studies then go to the Smithsonian), and...
