  • Commented on Two Thoughts
    Back in the late 60s and early 70s when the Shuttle concept was being designed and laid out the ability to launch separate vehicles and dock them in orbit was very much unknown territory. The few attempts to do such...
  • Commented on Two Thoughts
    Satellites are in an environment where they are "attacked" 24/7 with 1100W/m^3 of energy, the Solar Constant. The GPS constellations are well outside the Allen Belts so they also get beaten on by particles from the Sun, never mind X-rays...
  • Commented on Two Thoughts
    Even under perfect conditions any ground-based laser beam has to fight its way through fifty kilometres of atmosphere before it can "attack" a satellite. That really eats into the energy and focussing budgets of the original optics if the intention...
  • Commented on Two Thoughts
    Killing GPS/GLONASS/Galileo/Baidu satellites with mechanical attacks is not going to work, at least not without a lot more throw-weight in launchers than most folks in a shooting war can commit to easily. The GPS and GLONASS navigation broadcast satellites are...
  • Commented on Two Thoughts
    STOVL don't need a strip to land on in extremis. One of the loadouts for the Tornado was the JP223 dispenser meant to cripple a regular fast-jet or heavy transport runway by covering it with cratering bomblets, self-burying mines and...
  • Commented on Two Thoughts
    The F-16's range with external fuel tanks is about the same as the F-35 restricted to only its onboard fuel stores. Of course the F-35 could have been outfitted with dummy external fuel tanks to make things "equal" (filled with...
  • Commented on Two Thoughts
    Growing silicon crystals requires reliable amounts of power 24/7, same with refining aluminium. Solar is diurnal and fluctuates with the seasons and weather conditions, wind is unreliable. Hydro can be delivered on-tap with plenty of warning to customers when the...
  • Commented on Two Thoughts
    Again basic ROE for a wing of F-35s (two pairs) vs. a cloud of missile-armed Cessnas: 35,000 feet altitude, initial engagement distance 50km. How much radar and other eyes-in-the-sky kit do the Cessnas have? Can they each power a sky-search...
  • Commented on Two Thoughts
    Sopwith Camel vs. F-35, ROE - both aircraft begin at 35,000 feet at 50km separation. At night. My money's on the F-35....
  • Commented on Any Sufficiently Advanced Technology Is Indistinguishable From Cthulhu
    "The Geneva convention still requires warships and submarines to give civilian vessels time to abandon ship," Surely a submarine could only shoot to wound?...
  • Commented on Any Sufficiently Advanced Technology Is Indistinguishable From Cthulhu
    Famously the Chileans didn't say "pull the other one, that's got bells on it" when a Sea King helicopter ended up in their territory just over the border from Argentina, out of fuel and with no-one on board except the...
  • Commented on Any Sufficiently Advanced Technology Is Indistinguishable From Cthulhu
    I got to shoot early versions of the Accuracy International rifles on the Century range at Bisley but I was more of a pistol shot than being particularly competent with long arms. I did shoot at extended range with...
  • Commented on Any Sufficiently Advanced Technology Is Indistinguishable From Cthulhu
    Oh dear... You may have seen too many Westerns where the Good Guy shoots a pistol out of the hands of the Bad Guy[1]. There is no "shooting to wound" in real life. A police marksman discharging a firearm at...
  • Commented on That "Annihilation Score" spoiler thread you're all asking for
    Mo kept finding excuses to not hand Lecter back to the Laundry, to retire him, destroy him or pass him on to someone else. She kept him close while pushing Bob away once it was clear Bob was now a...
  • Commented on That "Annihilation Score" spoiler thread you're all asking for
    How many times has Bob nearly killed Mo, and how many times has Mo nearly killed Bob? Sure Bob's made a lot of mistakes but he's never pointed a lethal weapon at Mo as many times as she has since...
  • Commented on That "Annihilation Score" spoiler thread you're all asking for
    Basically Mo has been in a hot and steamy affair with Lecter all the time she's been married to Bob. It's only when she realises at the end of Rhesus Chart that Eater-of-Souls Bob is now a levelled-up threat to...
  • Commented on Reminders
    The Tor.com teaser still has some bugs -- Mo talks to a personable Deputy Chief Constable during the cocktail party on the oil rig in the Tor.com excerpt, not a Chief Superintendent as in the paper version of the book....
  • Commented on Crib Sheet: Equoid
    Moving the crop growing areas north as temperatures increase reduces the total annual sunlight those fields receive as the slant angle to the sun decreases and so reduces the total amount of photosynthesis per square metre of land. Some plants...
  • Commented on Shieldwall: Barbarians! Writing and self-publishing an old school boy's young officer story set in Attila's invasion
    The problem is where does a small clandestine facility get the energy to do this kind of separation? The power grid requirements for calutrons are immense and having a couple of 400kV supergrid feeds running into a two-story "muffler repair...
  • Commented on Shieldwall: Barbarians! Writing and self-publishing an old school boy's young officer story set in Attila's invasion
    Gaseous diffusion was easier to build assuming you threw money at it. The Oak Ridge diffusion plant built cost-no-object during WWII to make bomb-grade uranium was for a time the largest single building on the planet and required a good...
  • Commented on Shieldwall: Barbarians! Writing and self-publishing an old school boy's young officer story set in Attila's invasion
    Centrifuging takes less energy per unit of fuel-grade enrichment than gaseous diffusion, a better Energy Return On Energy Investment (EROEI). I've developed a twitch against the assorted molten-salt thorium reactor proponents mainly because of the religious hype and TED talks/Powerpoint...
  • Commented on Shieldwall: Barbarians! Writing and self-publishing an old school boy's young officer story set in Attila's invasion
    If the fluorine molecule is so dangerous then why is Poly Tetryl Fluoro Ethylene (PTFE) so inert? H2SO4, HCl, HF and the other common acids all have hydrogen molecules in them, UF6 doesn't. It's not particularly safe but it's not...
  • Commented on Shieldwall: Barbarians! Writing and self-publishing an old school boy's young officer story set in Attila's invasion
    Nearly all of the UF6 in store in the US and elsewhere is depleted uranium byproduct from centrifuge enrichment plants. It would cost money to convert it back to metal or oxide form whereas it can be used directly as...

    Equoids are Light Cavalry -- Blue Light Cavalry....
  • Commented on Book Launch
    Case Nightmare White would be when every other "colour" happens at the same time. See "Earthdoom" for a worked example. Case Nightmare Black would be when nothing at all happens....
  • Commented on Second childhood?
    There are a number of Japanese mangas that now publish chapters online followed later by printed collections to monetise the effort. In other cases web publication of a chapter occurs after regular magazine publication. There's also a move towards ebook...
  • Commented on Second childhood?
    I follow Yet Another Fantasy Gamer Comic (http://yafgc.net/) which is drawn by an artist who does storyboards for Hollywood and TV. It's a four-frame 'toon done in a sketchy pencil manner which adds to the flavour. It's your classical cod-medieval...

    Plutonium isn't needed in a greater-than-unity (GTU) breeder reactor (i.e. one that will produce "surplus" Pu that can be extracted and used in other non-breeder reactors), just a lot of high-energy unmoderated neutrons which can be obtained from U235. Thermal...
  • Commented on Shieldwall: Barbarians! Writing and self-publishing an old school boy's young officer story set in Attila's invasion
    You forgot the Soviet-era invasion by the western powers in the early 1920s, the invasion of Siberia by the Japanese in the 1930s and the pre-Soviet Russo-Japanese War of 1905 -- that one led to losses in Russian/Soviet territory that...
  • Commented on Shieldwall: Barbarians! Writing and self-publishing an old school boy's young officer story set in Attila's invasion
    The local rulers still got to rule (just like in Hawaii), it's just they did so at the sufferance of the administrators running the business side of things, the Customs officers, local military governors and the like. Kipling's stories of...
