    "I suppose one of the drivers for which base hull Astute or Virginia is chosen would be how much of a Tomahawk capability, if any, the Australians want?" None. They don't care. The actual armament hasn't been mentioned in public...

    Glass houses.... You really want to get into a fight where we come on here and announce every odd GW of infrastructure outage? 2008 Hinkley Point C got the go ahead from the government, along with 7 other plants. HPC...

    Sounds like a plan!...

    Speaking of which (missed deadlines) the James Webb Space Telescope has been pushed back again. I think they just realised that it has to be depressurised and they hadn't planned for that and it will be destroyed if it's depressurised....

    Not very big at all. Particularly if you reduce the apparent gravity. Even at 1g, 60m is thought to be fine after some adaptation. At 1/6th g, 25m should be plenty. https://www.researchgate.net/publication/318471827_Space_Settlement_Population_Rotation_Tolerance...

    "Um, you cut a data cable and the Internet doesn't collapse. A country cuts itself off from the Internet doesn't end the Internet. But most importantly the Internet isn't a massive power cable with no alternate routes." Neither is this....

    "Intercontinental HVDC is completely unfeasible both technically and geopolitically. [snip] so you're losing 45% to 60% of generated electricity just to transmission losses." Again with the efficiency... Nuclear loses about 60-70% of the energy before it leaves the plant. Coal...

    "Basically, having a supergrid that's reliant on very distributed power generation is very resource-intensive, because bidirectional long range transmission of electricity requires at least doubling the number switching stations (a step-down transformer is not a step-up transformer), and also grids...

    "Still got the problem with some asshole stealing it..." Every bridge or storm water drain around here used to have a brass plaque with raised lettering that said something like "Opened by the Rt. Hon. Joe Blogs esq Member for...

    Yes it's 6 reactors. Doesn't make any difference. (though I did say 3.2 GW, when it's 3.5 GW). The PLANT cost 14 billion to build, and now it's 13 billion to "refurbish". Yes, that 14 billion would be 23 billion...

    All this talk of "renewables only last..." while "nuclear lasts 80 with only a simple refurbishment at 40 years". It completely misses the reality to the point of being dishonest. I've pointed this out before, but here goes again. The...

    Oh, and for clarity, I'm not suggesting pumped hydro is the right solution. As you know, I'm an UHVDC fan from way back. The Scottish Scientist proposal depends on vast UHVDC interconnects to work, and to me, that seems like...

    Could well be nutters, it's my first contact with that site. However there's nothing I could find in the proposal that violated any physics or engineering. Obviously it will never be built, for all the same reasons that nothing that...

    Thanks, I hadn't seen that second one. Note that it finds that 160 GWh of storage is sufficient to ride out the calm of June 2014, but the first paper is a proposal for pumped storage of over 6000 GWh....

    I'm not really into eating fish, but the other divers took the opportunity to herd a fish or three into the hessian bag that we were using to collect the growth that would otherwise clog the cooling system of the...

    464, "where in Scotland do we have..." Here. https://scottishscientist.wordpress.com/2015/04/15/worlds-biggest-ever-pumped-storage-hydro-scheme-for-scotland/ Nearly 300 GW *days*. 465, "all the biomass starts decomposing and releasing methane" True, if you let it go anaerobic. A seawater pumped hydro won't go anaerobic if you use it....

    "So how long before you run out of new rooftops?" Currently about 1/4 of buildings have solar. A lot have small systems, 1.5 kW used to be popular. The systems being installed now are much larger, and the average rooftop...

    The inhabitable land available by that point will be: northern Canada, northern Siberia, Scandinavia, Greenland, and Antarctica (which will be pretty temperate by then). Habitable, but not arable. When permafrost and glaciers melt you don't get farmland, you get rocks...

    I wish I'd said that. If the UK wants to build 300 one GW reactors, I say "knock yourselves out". If you can vote for brexit, you can vote for anything no matter what it does to you. Even if...

    I'd also like to point out that the graph you pointed to that gives per capita increase over 15 years is intentionally misleading. Labeled "how fast can nuclear be built" it doesn't show how fast it can be built, but...

    Something went wrong with my formatting in my previous post. All of the following should have been quote italics; Yes, there is. It's called "learning curve" and is a standard occurrence in human industry. When you start building hundreds of...

    When you look at large-scale rollouts of non-fossil energy sources, hydro takes the podium and nuclear gets the second place. Then you have wind, and then you get solar. Australia currently rolls out 3 GW of rooftop solar per year....

    The advantage for the power company would be that the liability for operator error would rest with the government. This should reduce their insurance risk and thus the insurance costs. No nuclear operator pays insurance. I think in the USA...

    I don't know if there's a commercial satnav that does this. My newest satnav is a decade old. Teslas have it built in. In fact Teslas will start to precondition the pack to give you the fastest charge when you're...

    If only there was some way people could leave reviews on that computer with the date and time and a few words to say if the charger was ICEed or working or not. Maybe a map where chargers that aren't...

    The number of charging stations I have seen anywhere ever is still in single digits. Whereas petrol stations are large and conspicuous installations... You can't imagine my joy to hear from someone on the internet that their only way of...

    You can have a hell of a lot of accidents that have nothing to do with radioactivity. Things like lifting the condenser into place and then dropping several thousand tonnes of expensive pressure welded pipe on the ground completely wrecking...

    Interesting, you're both more optimistic and more pessimistic. I figure we need 25 TW. Nuclear seems to cost about 7 dollars per W (on a good day) 25 TW x $7/W, the Ws cancel, so that's 175 T$. I figure...

    Auricoma and Greg, Hetero pretty much have exactly what I was going to reply, but better phrased. The only thing I'd add in reply, "something must be done, and nuclear is something" is not a reason to waste 350 trillion...
  • Commented on Fossil fuels are dead (and here's why)
    Not only that, but the French made nuclear work so well, 40-50 years ago. When the costs were a state secret, the safety was a state secret, and accidents were a state secret. Now that isn't the case, it doesn't...
