  • Commented on Happy 21st Century!
    Gas is cheap and people pretend burning it doesn't add to global warming like coal does. Reactors are overengineered to assuage irrational fears of radioactivity and all things nuclear, stoked by the coal industry and Greenpeace cultists in the past....
  • Commented on Happy 21st Century!
    Your numbers are wrong, sorry. A typical nuclear reactor produces 1000 MW of electricity, quite a few produce less. Some of them are grouped into "plants" but the total amount of electricity produced around the world from the 460-odd operating...
  • Commented on Happy 21st Century!
    No, renewables have never been 100% of our electricity generating capacity. For one thing we get 6 to 7 GW from nuclear pretty much all the time. The rest is majority gas with some coal-burning in the winter -- we...
  • Commented on Happy 21st Century!
    Home solar presupposes someone owning a home which a remarkable number of people don't. There's also the urban problem, four or five-story dwellings with one roof and ten families living there -- who gets the solar power, who does without?...
  • Commented on Happy 21st Century!
    Pebble-bed reactors have been tried in the past and failed dismally. The Germans built two production reactors, one leaked enough radioactivity to be detected quite some distance away a few days after Chernobyl blew its stack, the other broke after...
  • Commented on Cthulhu Counterfactual
    For Americans 9/11 was a defining moment in their history, for me it was a Tuesday. Crazy people blew shit up and killed a lot of other folks, welcome to the IRA. I spoke with some young-ish Americans a few...
  • Commented on On hold
    One place this shows up is in the notion that our ancestors in the ice age were subhuman, even though their brains were bigger than ours. I don't think they were necessarily better nourished, but I do suspect those big...
  • Commented on Server upgrade coming
    Chrome on Windows, the site is doing some weird shit when I try and access it via https, I keep getting thrown back into "not secure" mode when I try and navigate anywhere. Using https for antipope.org/blog_static I get a...
  • Commented on Test Case
    The SPAS ain't that great mechanically speaking but it makes for good movies -- it's the basis of the "grenade-launcher" section of the M41-A "Bug Buster" in Aliens. A guy I knew in Cardiff got a SPAS-12 in exchange for...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    Thermal fossil and nuclear plants are built where the water is (frex the Labadie coal power station complex, one of the largest in the US is right next to something called the Missouri River), thermal solar plants are often built...
  • Commented on Test Case
    I happened to be in the US during 9/11, planning to fly back to the UK on Thursday the 13th. This didn't happen for some reason... When I did fly home from Hartsfield the following week (I got to go...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    Most coal, gas and nuclear plants are built near the sea or rivers to provide a heat dump for the condensers that turn the final-loop turbine steam back into water. Even where regulation requires them to use separate land-based condensers...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    CANDUs and AGRs (which can also operate during refuelling operations) get shut down regularly for inspection, maintenance, upgrades, repairs etc. The ability to run while fuel elements are swapped out is neat but it doesn't actually provide extra uptime compared...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    Grid solar uses surprisingly large amounts of water to clean solar panels and mirrors and since they're often sited in desert areas they tend to use local aquifers. See for example, the SEGS plants in the Mojave Desert in California,...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    Yes, the radiation risks are smaller than was once feared, but we simply do not know their exact magnitude. The problem is that the vast majority don't show up in easily-analysable ways, but as an increase in mortality and other...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    I was just adding something you forgot to mention since of course you'd hold solar panel production and waste sequestration to the same ultra-mega-super high standards of nuclear waste that it not affect the biosphere until the Sun enters its...
  • Commented on Test Case
    Despite the extra construction and material needed to put the rail at the top, I have never understood why people favour putting it at the bottom. Loading and unloading materials onto transports at ground level is easier than lifting them...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    It's the massive quantity of the solar panel production waste coupled with the ridiculously long time spans it's horrifically toxic which make it dangerous. But no-one cares how and where the solar panel production plants dump their waste, it's not...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    A significant amount of uranium production around the world is done by slipstream processing of other mined ores rather than being carried out in dedicated uranium mines. See, for example, the Olympic Dam mine in southern Australia for a worked...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    Actually those sorts of tabular analyses of deaths per Tw-hr do look at lifecycle requirements for energy generation, from production of raw materials and fuels through manufacture and construction, maintenance and eventual disposition of out-of-date equipment and materials. Nuclear uses...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    The idea the nuclear power is safe and feasible makes three assumptions. Assumptions are not needed. The table is from 2012, including Chernobyl and Fukushima. Energy Source versus Mortality Rate (deaths/trillionkWhr) Coal – global average 100,000 (41% global electricity)...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    Correcting you to be polite -- the British Magnox and AGR designs can also be short-cycled to produce weapons-grade Pu-239. Several countries bought a single Magnox reactor back when they were being rolled out in the UK, probably for that...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    If you want to sequester carbon in trees other than in forests, you'll need to put them somewhere dry where they can rest in peace without rotting. There's a lot of deep coal mines that could be repurposed for tree...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    Zero nuclear power station waste has leaked or been deliberately released into the North Sea over the past few decades from sellafield, it's all nuclear weapons production materials and waste. Anti-nuclear people often conflate the two because it's good propaganda...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    There were plans to investigate the idea of drilling deep holes, several kilometres down, into shield basalt using oilrig hardware to make small permanent repositories for things like medical and industrial gamma imaging sources (usually cobalt-60 and the like) in...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    It's probably too early to start the Finnish repository but they've got more than enough in the piggy-bank from levies on the nuclear electricity they've already generated to pay for it so why not start? Total cost is a billion...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    "Economically viable" means any estimate of reserves will vary as prices go up and down. Back in the 1980s British deep-mined coal was selling for about £50 a tonne (call it £90-£100 a tonne in today's money). If the price...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    Deep holes -- the shallow coal is all gone in the UK. Deep-mined coal in the 1980s in the UK was about 200 metres and more down typically. The further reserves left are deeper than that so more pumping, more...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    Your link is not "industry" but an eco-warrior blog grinding away at their axe. As fossil fuel sources dry up over the next few hundred years more effort will be put into extraction of what is today marginal sources --...
  • Commented on Solarpunk rising, or how to turn boring bureaucratic meetings into creative fodder
    The much smaller and more rural population back then generally avoided freezing to death in the dark by burning wood products, camel dung and other available bio-carbon materials. Sometimes of course they didn't survive -- Western folklore is full of...
