    "Rural" in US politics is code for "we have no black people here", just like suburban development was intended to produce communities with no black people. This gets used to produce a presumption of virtue. US politics only makes sense...

    Start a war on the Korean peninsula and you take a big bite out of the materially productive global economy; there's a lot of long-lead-time critical components coming out of South Korea. (The phone you have now will be the...

    Trump is a grifter. Trump isn't a politician and doesn't have any goals beyond garnering praise....
  • Commented on 2117 revisited
    Not "swap in place of charging"; "swap because a better battery tech has come out". (Or "the rest of the car is fine but this battery pack has been used up and should be recycled".) So if someone gets a...

    The obvious thing to use the salt for is sodium-chemistry batteries. (There really isn't that much lithium; there is lots and and lots of sodium.) Which leaves the chlorine, but there would presumably still be a need for bleach and...

    Remember the abortive recounts? http://www.palmerreport.com/news/ahead-of-recount-wisconsin-has-already-wiped-out-5000-phony-votes-for-donald-trump/234/ Vote counts are always off. If the errors are all in one direction, it's not an accident. It might not be organized, but it's not an accident. None of the states where Jill Stein put...
  • Commented on 2117 revisited
    We are very near the limits of unassisted comprehension/cognition, though. And we know with some confidence that history matters to neural-net AIs. So one outcome is that the preconceptions of whoever does the initial neural net education in a discipline...

    It's nigh-certain there were adjustments to the reported vote totals in Trump's favour in some swing states with Republican control of the state apparatus; it's absolutely certain that North Carolina and other states engaged in voter suppression of dubious legality...

    Which is where you have to hope that Macron has no lurking scandals (organic, synthetic, or otherwise) and that the security is very good indeed for runoff candidates....
  • Commented on The sudden eruption of news
    The bacteria in the nodules on a legume aren't from the legume; they're from the soil. https://www.britannica.com/science/nitrogen-fixing-bacteria and note the bit about "invade". Also the bit about "commercial culture". There are non-symbiotic nitrogen fixing organisms, and I cannot stress enough...

    The rear-locking bolt of the No.4 was considered better for long range -- 600 metres and out -- shooting because it damped better than front-locking bolts did. You saw No.4 actions with target barrels and fitments used for target shooting...

    Only works if the water's available. The political problem of saying "we need to cut the irrigated land by a third so the remaining land is irrigated *enough* is, well, challenging isn't going far enough. Chinampas -- farming wetland --...
  • Commented on The sudden eruption of news
    Read some time ago that various trees are especially good at taking out certain toxic metals. The City of Toronto cut a bunch of cottonwoods/poplars awhile back that had grown on former industrial land now up for redevelopment, and then...
  • Commented on The sudden eruption of news
    Area is area; if you want your overall fertile soil area to increase, you have to increase it where it is. It'd be going too far to say this is well understood, but there's a lot of successful empiricisms. What...
  • Commented on The sudden eruption of news
    The particular maize farmers I'm recalling are in US states starting with I -- Iowa and Indiana, I think. The thing about runoff is that it strips soil; it's not primarily a problem of runoff adding nitrates downstream (which is...
  • Commented on The sudden eruption of news
    Fertilizer is required as an input in large part because the farming practices promote damaging runoff. There are several maize farmers who decided (for obviously personal reasons) they weren't dealing with fertilizer companies some time ago -- in one case...

    This gets into taxonomy, and it's way outside my understanding, but so far as I recall being told back in the 1980s, none of the math was new. A lot of the math was being repurposed, but the actual underpinnings...
  • Commented on The sudden eruption of news
    Graydon's brain decided a context of food security rather implied that bit, and didn't bother to flag it as an assumption. (Lo! the utility of review!) The real spec is tricky; you don't want to insist on equivalent area (because...

    Even if we want to insist on electrons, the telegraph signalling system of the Army of the Potomac looks a lot like a WAN. (for a certain value of "wide", anyway.) Go into camp, roll out the wires, and the...
  • Commented on The sudden eruption of news
    Lasers come from masers pretty continuously at Bell Labs which is 50s. (Pretty much the whole of the 1950s) And while VLSI didn't take off until the 80s the optical mask tech innovation it sits on is (at least IIRC)...
  • Commented on The sudden eruption of news
    Graphene belongs in the general category of meta-materials, things that don't have the physical properties you expect. (E.g., negative index of refraction.) Any economy sits on food. People generally lose track of this because so few people are directly involved,...
  • Commented on The sudden eruption of news
    One way to look at the economy is that it's built on innovation nigh-entirely happening in the 1930s.[1] (Gas turbines, high performance ICE engines, microwaves, transistors, light metal refining, chemical synthesis...) Those innovations are played out; there isn't any more...

    Well, sure, but keep in mind that if the tip of the bottom blade is passing 20m above the ground and the tip of the top blade is passing 60m above the ground, the wind speed and thus the thrust...

    The estimates are historical. The present is a departure from the historical....
  • Commented on The sudden eruption of news
    That three-blades-on-a-pivot design for windmills has had a shed load of work put into it, both empirical and theoretical. It's not easy to make an efficient windmill; vertical axis windmills have many obvious virtues (the generator can be bolted to...

    It's just a matter of money. There probably isn't enough lithium, considering global storage requirements. But there's that Harvard team working on flow batteries, the Australian team working on flow batteries, Goodenough's (yes, really, that's his name) team's solid-electrolyte batteries,...

    And it gets worse when economic gets involved. (Since you want to extract useful power at 2 m/s.) This is one of the reasons I think ocean wind (trimming sails is an old technology) is a better bet than terrestrial....

    I think the PRC is going for coal replacement with solar. They're not part of the thalassocracy, they're certainly not part of the oil empire, they don't have an entrenched fossil carbon power block to anything like the same extent...

    I don't think they're willing to shoot themselves in the head. Another fifty years of coal is way into "strap block of C4 to head, detonate" territory....
  • Commented on The sudden eruption of news
    "Absent the CO2 emissions problem" is a lot like saying "other than being shot in the head". Food security fails first. This is obvious to the meanest intelligence and you can watch it happening in the present. I don't think...
