  1. Re:Waiting for Dave's rant on this on A Device That Can Pull Drinking Water From the Air Just Won the Latest XPrize (fastcompany.com) · · Score: 1

    People need a lot less oil than they need water. Transporting water by pipe quickly becomes infeasible.

  2. Sure, but in low light conditions, pupil is already maximally dilated, even when not in an alert state.

    The point is that it doesn't make sense for pupil to be in suboptimal state when not alert. It doesn't cost anything.

  3. If bigger pupil is better, why aren't they always big ?

    Anybody with some experience in photography knows that bigger pupil/aperture results in fuzzier image. You lose depth of field. Also, the further you go out to the edge of the lens, the more distortion and aberration you get. On the other hand, tiny aperture is also bad because of diffraction effects.

  4. causes our pupils to dilate so that we can take in information more easily.

    What ? How does that work exactly ? Bigger hole = more bandwidth ?

    Two Finns go into a bar, and order beers. They drink the beers in silence, and when they finish them, they order two more beers. Still without saying a word, they finish the second set of beers, and proceed to order a third glass. Halfway the 3rd beer, one of them says: "good beer", to which the other replies: "did we come here to drink or to chitchat ?"

    No, it's the other way around. The value of bitcoin determines how much effort people will put in mining.

    The word "intrinsic" is misleading. Nothing has intrinsic value. Value always depends on context.

    We had the same heating [wordpress.com]from ~1915 to ~1945 as we saw from ~1970 to 2000

    Looking at GISS LOTI numbers directly, I see about 0.3 degrees heating from 1915-1945, and about 0.5 degrees between 1970 and 2000, and about 0.75 degrees between 1975 and 2015.

    I recommend you do the same, instead of relying on Bob Tisdale's graphs.

  11. ENSO moves heat between atmosphere and ocean, so it influences average temperature of the surface air which is what we usually talk about when discussing temperature.

    People cannot always move over to the left lane if there's no gap there, or if that lane is moving much faster. The cannot always keep their speed either, because there may not be a gap big enough on the lane you're trying to merge in. When they slow down, the gap in front of them gets bigger, and you can safely slip in there.

    As long as self-driving cars and human-driven cars mingle on the roads, the self-driving cars should err on the side of excessive caution rather than insisting on legal right-of-way.

    Won't work. If the car is recognizable as self-driving, and it is known to be super cautious, people will stop yielding to it. It needs to be driving like a human, claiming its space, and forcing other cars to brake to avoid accidents.

    I always found it fascinating that CO2 levels moving from 200ppm (0.0002) to 400ppm (0.0004), a change of 0.0002, is the cause of all this warming.

    If you compressed the atmosphere to a layer of equal density, it would be about 8 km thick. If you're walking outside in the sun, wearing 2mm thick sunglasses, the ratio of sunglass to atmosphere is 0.25ppm.

    Do you find it fascinating that 0.25ppm worth of sunglasses blocks most of the light ?

    If we moved all the CO2 from the atmosphere to a single pure layer, then 200 ppm would mean a layer of 5 feet, and 400 ppm would be 10 feet. IR works as a "sunglass" for IR.

    Also, although money flows out of the country, goods flow in

    Money is nothing but a standardized form of IOU. The US dollar is valuable, only because it carries a promise to the recipient that they can give back the money to the US, in return for something (goods, labour) of equal value. If you keep promising for decade after decade, and never return goods of equal value, you're borrowing for imported goods, just like a drunk is borrowing from the bar when he lets the tab run up and never pays it back.
