    I follow Japanese anime and there have been a noticeable number of shows in the past year or so that have had delayed episodes and even entire series going on hiatus. In some cases the voice actors have been reported...

    I use the short-hand "SOTR 2" to differentiate the American Civil War of 1861-65 from the previous unpleasantness that occurred in 1776....

    I like numbers. Roughly speaking, a First World citizen such as a Briton uses about 600W of electricity on average throughout a year. That's winter and summer, day and night, asleep and awake, adult and child. Some advanced nations use...

    The real technical issue is that it is easier to roll out renewables than build nuclear; It's even easier to build gas-fired generators and that's what we've done in the UK (ca. 35GW OCGT and CCGT capacity, I've seen 30GW-plus...
  • Commented on Decision Fatigue
    Gas in the form of CCGT plants is almost an instant-on suppler of electricity, half an hour or less from cold to several hundred MW on the grid (they can provide maybe 500MW quickly, it takes another fifteen or twenty...

    As far as I can tell the Coire Glas pumped-storage scheme is still in the begging-bowl and PowerPoint stage of development, I don't think it has even cleared the environmental impact evaluation stage. Again you make the mistake of assuming...

    That's great as long as folks don't want to charge their cars in winter when insolation per diem drops to about a fifth or less of the average figure. Here in Edinburgh, Scotland the sun rises around 09:00 and sets...

    Wave power is one of those technologies that gets some PhD money and occasional front-page filler articles about free energy and renewables followed by silence since the abandonment and decommissioning of the project after a year or two isn't news...
  • Commented on Decision Fatigue
    I've encountered at least one academic exercise of a reactor building design made almost entirely from steel, a material that is infinitely recyclable. It doesn't add much to the total cost of the construction and simplifies decommissioning at end-of-life. Licencing...

    It's also entirely possible he doesn't notice them at all. They're not car-shaped or truck-shaped and rare enough that his conscious mind assumes that a bicycle-sized object travelling at road speeds (50mph plus) equalling or exceeding his own speed is...

    I have seen an unsourced claim that Teslas have suffered 38 fire-related deaths from approximately 3 million cars sold. This is compared to another gasoline car which had 25 fire-related deaths in approximately the same number of cars sold. The...

    The usual motorcyclists' mantra is that you assume everyone else on the road is actively trying to kill you, and ride accordingly. It may be technically a bit of an exaggeration but in practical terms it's realistic advice. True, this....

    I'm talking about Aluminium-Sulphur chemistry, which does not require molten sodium metal. What it does require is molten aluminium salts. The electrochemistry is complex, which is what seems to have held up progress. But the basic idea is an aluminium...

    The Youtuber Zeihan opines on a lot of things. His level of expertise on any of these things is another matter....

    The structure overheads for electric vehicle batteries actual decrease as the battery pack gets bigger -- the proposed Tesla semi-truck battery is reported to be 6000kWh but it weighs less than four tonnes, so it's better in terms of overall...
  • Commented on Decision Fatigue
    I don't see any real "game-changing" batteries on the horizon. Lithium-chemistry is about as good as it gets for volume, mass etc. in mobile applications and there are hard physical limits on capacity per kilogram of battery material that we're...
  • Commented on Decision Fatigue
    There are sodium-based batteries already out there, on the market for nearly twenty years now. NGK in Japan has been making sodium-sulphur storage batteries and selling them for mere money for that time, and only a few of them have...
  • Commented on Decision Fatigue
    Britain has a lot of gas-fuelled generating plant and right now gas, although more expensive than last year is cheap enough that exporting gas-fuelled electricity to the rest of Europe at a time of high wholesale electricity prices is good...

    I had a look at the Snowy River scheme when it was mentioned on this blog a little while back. The 350GWh figure touted in the headlines is a bit like the figures published for wind and solar farms, a...

    Pumped hydro is not impossible, there are many implementations of such schemes around the world. Most of them are not economical to operate on a dollars and cents basis but they are comforting backstops to Black Swan events and unfortunate...

    For the UK at least, more pumped storage or even battery storage is not needed, at least at grid scale. We simply don't generate "excess" electricity from intermittent sources, renewable or otherwise so there's no unused energy to store. It's...
  • Commented on Decision Fatigue
    Electricity storage en masse is pointless as long as half of the world's electricity generation is fossil-fuel powered, AND WILL BE FOR THE NEXT TWENTY OR THIRTY YEARS AT LEAST. Why bother burning gas and coal and storing that energy...
  • Commented on Strong and Stable!
    There is a Golden Age assumption of railways in the past which assumed that middle-class folks were the only people around. Working-class people couldn't afford to travel by railway, other than maybe once or twice a year if they could...

    It was a strange scenario that was being postulated, that Russian oil was going to freeze in the pipes and destroy the entire industry because, something something. There are several obvious solutions to this issue, including piping oil down one...

    Russia is still delivering gas to Western Europe and getting paid to do so. The best that the European consumers can get is a fixed-price cap on that gas as "sanctions"....

    The Trans-Siberian rail line[1] is still operational and oil and gas can be and is regularly transported to China via rail tanker cars. It's not as efficient or cost-effective as pipelines but it works. Russia and China have been working...

    It's why my kids all tell me that they don’t expect a dime from Social Security when they retire. This has been a recurring trope among Americans of a certain stripe since at least the 1990s. A particular Fiendish Disputant...

    The 2GW interconnector failed earlier this year -- there are two separate 1GW connections but they both terminate at the same station on the south coast of England. One connection had a fire in its switchgear and that meant the...

    Assuming you're running Windows 10 or Windows 11, try using the screen recorder function that's part of the Windows Game subsystem. Select a Youtube video, make it full-screen and then hit [Win key] + [Alt] + [R]. That should start...

    More hydrogen gets lost than helium because there is more hydrogen in the atmosphere in the form of water vapour, methane etc. and of course helium doesn't form compounds the way hydrogen does since it's a noble gas. The process...
