  1. Re:Great.. Methane.. on China Successfully Mines Gas From Methane Hydrate In Production Run (oilprice.com) · · Score: 1

    Given the choice between burning methane and burning coal, burn methane.

    Given the choice between burning methane and letting it bubble out ("Laptev Sea methane emissions"), burn methane

    Both choices must be temporary, whilst mankind embarks on a crash-plan buildout of nuclear power - with the best will in the world trying to do it with "renewables" simply isn't practical(*) or indeed possible(**). We may already be too late to prevent an anoxic oceanic event - which might sound like a good thing the way some pave-the-earth types spin it, but half our breathable oxygen comes from the oceans.

    (*) It costs too much compared to nuclear power and generates too much CO2

    (**) Ignoring the safety aspects of blade-off events(***), and pollution from solar PV manufacture(****), Carpetting populated areas with windmills and solar PV would _just about_ match current electrical generation capacity. Unfortunately electrical generation currently only accounts for around 35-40% of current carbon emissions and moving to a more-electric future by reducing carbon-sourced heating and transportation will increase that electrical demand by a factor of around 8-10 once transmission losses are taken into account.

    No, you can't just build massive solar arrays in deserts. The oft-touted "Sahara for Europe" project would be stealing energy that Africa has a rightful claim to (colonialism writ large yet again)(+) and in any case the transportation infrastructure alone would be the single largest project that humanity has ever embarked upon - and that's quite apart from the much larger issue that it's only economic to move electricity about 1500 miles at most before energy losses stop making it worthwhile.

    (***) 2MW turbine blades have been known to go almost 2 miles.

    (****) pollution around Chinese manufacturing sites is so bad it's putting potable water at risk for tens of millions of people. Flint MI is small fry.

    (+) The developed world cannot hold back developing countries without risking all out war and planetary chaos (and in any case it wouldn't work in terms of reducing carbon emissions). Access to cheap energy is crucial to improving quality of life and has been the driving force of most civilisations over the last few thousand years (slaves replaced with wind, water and then electricity, carbon). Those populations will burn oil/coal/gas if they can't get cheap nuclear electricity and it's in our collective interest to give it to them - as people get lifted out of poverty they have fewer children and the only way to avert a complete ecological collapse is to reduce the overall human birthrate below 1.6.
    Contrary to popular opinion, wars and famines don't reduce populations. Within 2 generations the losses have always been made up - and then some.

    Low production, low paid jobs are difficult to economically justify robotizing. You might save a few tens of thousands per unit purchased over the life of the robot, or you might only break even/lose money.

    On the other hand, robotising or automating/augmenting high skill but highly algorithmic jobs pays off a lot more per unit purchase.

    It's already been happening. People do more, with fewer staff right across the board. Whilst there's a claim that office productivity is down on the 1960s, the reality is that actual staff numbers are significantly lower - receptionists, telephonists, typists, runners, copyists, stenographers, account clerks etc are frequently rolled into one job.

    In the near-to-mid term future, you're going to see a lot more redundant bankers, market traders, sharebrokers, programmers, accountants and lawyers than burger flippers or labourers - and jobs like plumbing/electrician etc will take even longer to automate out of existence even if automation reduces the workforce.

    Driving is one area where there's a lot of concentration - but in that area it's not so much because of pay rates (which are low) as restrictions on allowable working hours, the need to return to base frequently and the costs when drivers make serious errors or fail to heed mechanical system warnings. Whilst the push is for "self driving cars", "automonous commercial vehicles" is actually where the payoff happens.

    "the European buffering capacity of the network"

    AKA "The very large French nuclear reactor fleet in the country next door (which happens to be France)", which has some load-following ability.

    "Renewables" in northern europe have the potential to replace all current carbon emitting sources - if the entire european countryside is carpetted in turbines and glazed with solar panels, at a cost several tens of times higher than the carbon-emitting sources (and the fuel) they replace.

    Eliminating OTHER sources of carbon (heating, transportation, industrial processes) will require an increase in electrical generation by a factor of _AT LEAST_ 6 if not more. The only way forward is massive investment into nuclear sources and nuclear research. We _need_ LFTR technology and we need it deployed at least 10 years ago. The ironic thing is that LFTR's inherent ability to load-follow without penalty means that whilst it's an ideal backing source for "renewables" the overall lower cost of operation (an removal of the need to subsidise, as LTFRs are carbon-neutral) means that the deployed renewables fleet would become white elephants overnight.

    When you factor in the requirements for increased energy availability in developing countries, the need for nuclear sources is clear. Even in equatorial areas the investment required to ramp up production of "renewable" energy dwarfs the cost of a few nuclear plants (conventional or LFTR) and without low-cost reliable energy, we cannot continue to both pull people out of poverty AND reduce the population (well-off people have fewer kids. Making people better off is the only _proven_ way of curbing population growth. Wars, Famine and Malthus effects have _all_ resulted in population bounces which more than made up the losses within 2 generations.)

    Those nuclear plants are likely to be chinese, and the LFTR plants will almost definitely be chinese - they're the biggest player in R&D into making LFTRs viable. It'll be interesting to see how fast chinese industry hoovers up both Thorium and "nuclear waste" to feed their plants in the next 20 years.

    The reason I suggest solar heat panels is because they're cheap to manufacture and maintain, making the 5-10% potential heating costs saving worthwhile aiming for.

    If you wanted to get really whizzy you could store solar heat in the ground in summer and extract in winter but that's a massive complexity boost with long payoff period. On the other hand schools tend to have large open fields where the pipework for such systems can be laid relatively easily and deeply.

    "Solar power has almost zero downsides."

    Apart from the massive amounts of nasty environmental waste being produced in China (where most come from) that's threatening the potable water of a few tens of millions of people downstream.

    Hydroflouric acid in particular is something you don't want in your waterways.

    In northern latitudes, you'd be better off thinking about solar heat panels and suchlike to offset your energy costs, but solar PV is generally a waste of space unless you're off-grid and away-from-grid (in many cases the cost of solar is a lot more than the cost of a grid connection), or using it for low energy-density applications (I'm pretty sure that even those solar-panel equipped streetlights will need topups in winter months if used in the UK)

  12. Plenty of large software companies have done it, some have been american and some have been _very_ large. I'm aware of a couple of cases where a superinjunction was sought (and granted) - a superinjunction means that you can't even drop hints that there's a court case.

    Personal opinion: Given the exploits are in use by greyhats (spy agencies), then blackhats probably have them anyway and rapid disclosure is the prudent path so that whitehats can man the barricades.

    MS and others used to be notorious for not fixing bugs in a timely manner.

  13. The problem is that time and again when given a deadline to fix, vendors have gone to court to try and prevent the exploits being published.

    If there continue to be warm water incursions from the Atlantic there's a very real risk of a clathrate slump offshore from Siberia (the Laptev Sea methane venting is showing no sign of abating) and if that happens then apart from the tsunami damage the longer-term effects are likely to be nasty. Dissolved oceanic methane levels are already problematic and there's a strong possibility of an anoxic event already being underway.

    The current problem is that the Progress turbofan engines on them aren't very efficient (or particularly reliable, despite being made modular for easy repairs) and that coupled with needing a crew of 4-8 means that the planes have higher operating cost per tonne/km than haulers want to pay.

    Couple that with legendary Russian "built like a brick shithouse" engineering - which is great for flying into unimproved runways, but again makes the economics not so hot and the hassles of flying a type which isn't homogenous and more large operators won't go there.
