    Suggest looking up the geology of ignimbrite and the conditions in which it forms, as those are the conditions expected to pertain over maybe half the earth. Gigatonnes of incandescent debris raining from orbit. A long winter, maybe a year...
  • Commented on Oh, 2022!
    A while back there was talk about charging for the excess generation over a certain level, but can't remember if that was satire or not. It was real, and some politicians still say this. It's to punish early adopters, hopefully...
  • Commented on Obligatory Hugo eligibility post
    Actually one of my supervisors was seriously keen that I target my first paper, a scoping review, at the (quite new) Lancet Digital Heath (an open access journal). Would have blown my "research support" budget and required a contribution from...
  • Commented on Oh, 2022!
    Leaving aside the people freezing part for a moment, this is all an argument around where certain industries need to be sited in a post-carbon world. I'm not making any serious guesses around the likelihood of movement actually occurring, to...
  • Commented on Oh, 2022!
    As I said, the UK could practicably take power from Morocco, but not South America let alone Australia. I agree with this bit! The real question is where does the sun go when it quits Europe, and line losses are...
  • Commented on Oh, 2022!
    Sigh, or quel dommage! I also heard that the Nuer believe in the exact same concept of the Holy Trinity as an obscure Midlands Methodist congregation, proving that Christianity is universal and stuff....
  • Commented on Oh, 2022!
    What about enough power, on a cols, still, winter's night so that people can have nont-freezing homes??? That isn't what "baseload" means. If that's your requirement, then the overnight capacity requirement is orders of magnitude less than that demanded by...
  • Commented on Oh, 2022!
    each region really needs twice as much generating capacity as its own peak demand, if not more to keep everyone else supplied with renewable energy 99% of the time Sure. Depending on how you draw up the regions, that sounds...
  • Commented on Oh, 2022!
    We have to have baseload power Okay, so 19th century advances in worker's rights mean nothing and all that time and money spent breaking unions so that mill owners could get some use out of that overnight power for continuous...

    Did you confuse Helsinki with Stockholm? Well no. Context is everything, and the context was about how feasible it is to build a high-speed rail line from Helsinki to Berlin (around the other way, through the Balitc states). I'm aware...
  • Commented on Oh, 2022!
    You could have high speed rail from Helsinki to Malmö, and from Copenhagen to Berlin. Then to transit over both routes you'd need to walk across the Øresund Bridge wearing a trench coat, tapping a cane and holding a lit...

    the real problem is, as it is with almost every other form of power except nuclear, a lack of storage capacity I think this is half true, albeit a bit tangled and to the point where some of it is...

    All of which makes Greg Egan's recent novel Perihelion Summer really quite instructive....
  • Commented on Oh, 2022!
    I think, from my perspective living in Brisbane, the irony is that Sydney, being above 30º, is in Greg's half of the planet....
  • Commented on Quantum of Nightmares
    So just by way of the OP, and keeping up to an extent, QoN came out on Oz Amazon on the same date as the UK ebook, though obviously we with the argumentative feet live in the recognisable not very...
  • Commented on Oh, 2022!
    It's kinda weird that most of the sand in the concrete in the megastructures in Dubai comes from Australia, even when it's mostly Australian engineering firms using it there. Desert sand is wrong for construction, as you're alluding, so it...
  • Commented on Quantum of Nightmares
    The need for burst communication was a major plot point in the John Le Carré novel The Looking Glass War, where a mothballed military intelligence team which had been active during the war revives and attempts to infiltrate an agent...
  • Commented on Oh, 2022!
    It looks like this is already being done. I found this page when looking up electric tugs, but I note it also links to this page offering "containerised maritime energy storage"....
  • Commented on Oh, 2022!
    A possible alternative to my numbers above (that is, carrying enough batteries to run full power from Osaka to Rotterdam takes 20% of the cargo capacity, all else being equal) is to arrange the batter containers in vertical stacks, so...

    Queensland has been electrifying its coal train network with 25kV overhead lines and 3 x 3MW locomotives per train. It's amusing but also a bit depressing to consider how BE locomotives might be used for this, given we should be...
  • Commented on Oh, 2022!
    Back of an envelope calculations... a TEU container has approx 33.2 cubic metres internal volume, while energy density for LiFePO4 is about 325 Wh/l, so you get roughly 10MWh per TEU, with roughly 3 cubic metres per container set aside...
  • Commented on Oh, 2022!
    "wheeled battery ballast," basically semis that are battery packs. Or even standard shipping container battery packs. There's some prior art for this: before "cloud" really took off, and I'm sure still since, both Google and Dell have marketed "data centre...

    Meanwhile, the sedans I prefer get squeezed out aside from short-range urban commuters. I think it's just a matter of the market being tested and a variety of configurations being tested. I thought it was cute that the first image...
  • Commented on Omicron
    It's just giganticly shit. One of the deaths in Queensland this week was a fully vaccinated 30-year-old with no prior conditions, whose complication was myocarditis. The new CHO, who had recently advocated for "this is the right time to let...

    I think you had it right the first time. The anarchist position is usually that you can have a decent society without overarching coercive institutions like governments, and manage it through voluntary institutions like co-operatives and clubs. Leaving aside this...

    I've been in a car where the kangaroo, albeit clipped by a glancing impact somewhere between the front of the car and the top of the windscreen, went right over the top of the car and landed in bushes a...
  • Commented on Omicron
    It's quite good for showing that many of our standard tropes about the development of culture civilization were molded out of bovine excrement and other found materials for various and often imperialistic purposes. What they propose to replace the bullshit...

    They're also the lowest of the low on the pay scale, although you can make reasonable money off of Overtime Pay if you're willing to work 60+ hours per week. The difference here is that overtime pay is less common,...
  • Commented on Omicron
    I think it's just some confusion about what the roles are in hospitals. The people who are in charge of hospitals, at least over here, are usually doctors who've gone into management. Administrators are the people on reception desks and...
