  • Commented on Sad Trombone Exoplanet Reality Check
    Radioactive decay doesn't work that way, and transmutation and fission are not radioactive decay....
  • Commented on Reality is broken
    I've been to a couple of the summer Comiket events in Tokyo which typically top about 550,000 attendees over three days. The main method of getting to and from the site for nearly everyone who attends is a commuter-style railway...
  • Commented on Sad Trombone Exoplanet Reality Check
    One of Bob Shaw's Serious Scientific Lectures postulated a space drive powered by beer drinkers, utilising the odd property of beer in that drinking one pint of beer results in more than one pint of used beer (or Tetleys as...
  • Commented on Sad Trombone Exoplanet Reality Check
    A company I worked for hired a young woman who built an 8-bit processor from TTL gates and chips as a hobby. She only had an HND and not the usual degree required by the HR people but it was...
  • Commented on Sad Trombone Exoplanet Reality Check
    A crash helmet lined on the inside with a thin layer of C-4 plus detonator is probably the fastest and most painless way to go since the shockwave will outrrun the neuronal activity in the brain that's saying that it...
  • Commented on The iron law of development
    Yet another "wonder battery" press release promising the moon on a stick and we're supposed to take it seriously. Really? About the only wonder-battery tech I've actually seen delivered and shelf-ready after the press releases had stopped has been Toshiba's...
  • Commented on Reality is broken
    The Buk-M1 AA system is not the sort of thing "untrained gunners" can operate. It's a tracked-vehicle system not a MANPAD or similar, crew-served with a team of specialist operators with years of training under their belt. It's not a...

    And here's the simple credibility test. If Russia hasn't been sponsoring the fight in Eastern Ukraine, then a) where are the rebels getting all of that heavy military equipment from, and b) why are all those Russian soldiers getting killed...

    The Pointies are a strategic reserve held ready for another Out Of Context problem of the sort their initial appearance caused. They have unique capabilities which might mitigate unique situations that cold iron will not necessarily deal with expeditiously....
  • Commented on The iron law of development
    Now now, rules like evacuation zones only apply to nuclear power plants not fluffy-bunny renewable generators. Hell, when the gas and oil terminals at Chiba burned after 3/11 nobody thought to evacuate east Tokyo despite the thousands of tonnes of...
  • Commented on The iron law of development
    The NGK battery farm at Rokkasho I referenced above has the individual 2MWh battery units standing in the open separated from each other so if and when one of them lights off it's unlikely to trigger its neighbour(s). They hope....
  • Commented on The iron law of development
    I've talked about this before but combustion is just a special case of oxidation. Rust (oxidation) takes minutes, combustion takes seconds explosion takes milliseconds and detonation takes microseconds. I'm not saying that lithium ion batteries explode per se, they burn...
  • Commented on The iron law of development
    Sodium-sulphur (Na-S) battery tech is on sale and deliverable today for static energy storage. NGK have been developing and building MWhr-sized units for about a decade or so. https://www.ngk.co.jp/nas/case_studies/rokkasho/ This is a 245MWh Na-S battery store used to stabilise a...
  • Commented on The iron law of development
    Gasoline is a liquid and requires it be mixed with oxygen or air before it will combust. There's a laboratory stunt where a burning splint is plunged into a jar or gasoline and it doesn't set off a raging inferno,...
  • Commented on The iron law of development
    I've been reading about flow batteries for decades. I don't see any for sale at a reasonable price anywhere. Lots of research, lots of glossy brochures and Wired articles but no cheap deliverables. There's a lot of energy storage battery...
  • Commented on The iron law of development
    There's also the problem of parabolas. Guns, even smoothbore muskets can outrange a bow because the bullet's path is flatter. That allows ranked soldiers with guns to engage bowmen outside their own effective range as long as they stand in...
  • Commented on The iron law of development
    Am I crunching the numbers correctly? Dirk's reference above suggests a theoretical silicon-lithium maximum of 2.3Ah per gram of battery. Assuming a potential of 3.7V for the cell, the usual figure for Li-tech batteries, that's 10Wh or 36,000 joules stored...
  • Commented on The iron law of development
    There's that word, "theoretical". Also "calculates". Pardon me if I don't hold my breath waiting for these to appear on the market at a few bucks per kWh of storage. Static grid power storage isn't really concerned about volume or...
  • Commented on The iron law of development
    A long time back I was discussing lithium batteries with someone who thought there was a conspiracy by the oil companies to prevent manufacturers from making large batteries because they wanted to prevent electric cars from being taken up en...
  • Commented on The iron law of development
    Cheap batteries will arrive aobut the same time as cheap energy, cheap money, cheap beer and cheap pizza. Electrochemical batteries are about maxed out in capacity per kilogram of materials to the point where they make quite good hand-grenades if...
  • Commented on Who wins? Cthulhu or the Emperor of Mankind from Warhammer 40K?
    It seems to me that a robot that can understand and reply to speech, and that has any sound output capabilities at all, should also be able to utter speech - not just in English, but in all those other...
  • Commented on Who wins? Cthulhu or the Emperor of Mankind from Warhammer 40K?
    I think you're missing my point. R2-D2 might well have been able to speak English or Yuuman or whatever human language(s) the sapients of the film's milieu ("A long time ago...") spoke, but why should he? Chewbacca didn't, Jabba the...
  • Commented on Who wins? Cthulhu or the Emperor of Mankind from Warhammer 40K?
    Batman vs. Judge Dredd was a draw, mostly. He did get arrested -- "Vigilante. 20 years in the isocubes." but it worked out in the end. Battle of the Chins doesn't begin to describe it......
  • Commented on Who wins? Cthulhu or the Emperor of Mankind from Warhammer 40K?
    R2 speaks perfectly clearly. He just doesn't speak English, in the same way Chewbacca speaks in a comprehensible manner, ditto for Jabba the Hut. It's actually a tribute to the scriptwriters that they can make it clear what the intent...
  • Commented on Who wins? Cthulhu or the Emperor of Mankind from Warhammer 40K?
    out of curiosity, are there games that teach/require similar thinking to whatever military folks do when out militarying? Hide and Seek is a good one. "If you can be seen you will be killed." Pass the Parcel with live hand...
  • Commented on Who wins? Cthulhu or the Emperor of Mankind from Warhammer 40K?
    On the topic of "versus" battles and metaphor/story role, I'm reminded of that old essay about if a modern military force popped up in Middle Earth during the War of the Ring. Kill every orc, arrest Saruman, destroy the ring,...

    Scotland most certainly is NOT fossil-fuel free for electricity generation. Peterhead power station is a generating station that uses North Sea gas to produce as much as 750MW using secondary plant usually over winter when demand is high. Its normal...
  • Commented on Who wins? Cthulhu or the Emperor of Mankind from Warhammer 40K?
    I wonder how the Emperor or Chthulhu would fare against Nathan Brazil? Heck, even Mavra Chang and Obie would curb-stomp them in a slow walk....
  • Commented on The iron law of development
    Some of this will be survivor bias -- there was a lot of cast iron produced from the 1800s onwards and some of it has survived due to circumstance when exposed hence its notability. There's also misidentification of old wrought...
  • Commented on The iron law of development
    The "laser-tag" rifle adaptor is used for squad-level fire and manoeuvre training, close-quarters combat and the like -- fun-house setups or urban village training areas. Basic rifle training carried out with live ammo happens on ranges to get the soldier...
