    Option 3 would have resulted in millions of Japanese starving to death. Their distribution system was demolished. As it was, tens of thousands of Japanese died of starvation that winter, and that was with massive US food aid.

  2. Re:Electrodynamic de-orbit tether... on Space Junk Getting Worse · · Score: 1

    Put into orbit a roll of Kevlar that unspools to be a thin sheet 20 meters long by a few kilomiters from top to bottom. Solar panels on top and a conductive loop around the perimeter so it can use the Earth's magnetic field to maintain orbit (or go into higher/lower orbits to avoid working satellites).

    Put it in a retrograde equatorial orbit with its surface plane parallel to its direction of movement to minimize drag. Any bits of debris that hit it will probably have a velocity vector such that all the collision debris will quickly fall out of orbit.

  3. Re:Can aircraft keep ahead of missile tech? on Russian Stealth Fighter Makes Its First Flight · · Score: 1

    In WW2 the US had automated AA guns. Outputs from radar went through an analog computer, which controlled the guns. They were extremely effective. They were first used at Anzio and were definitely used in the later parts of the Pacific war. IEEE Spectrum had a really good couple of articles on WW2 electronics a while back. And yes, those articles made it quite clear that proximity fuses are wonderful things. Radar at frequencies that Nazi U-boat commanders can't even detect is pretty nice to have too.

  4. Re:Scalzi on Stross on ST on Why Charles Stross Hates Star Trek · · Score: 1

    I took a class in neural networks almost 20 years ago. One project was to get a small network to "learn" how to recugnize handwritten numbers. On a 486/33 running overnight it got to the point where it could recognize a number right over 90% of the time, just with a a few dozen neurons. However, it would probably be impossible to determine *why* that network was able to recognize the numbers.

    Consciousness (however you want to define it) is almost certainly an emergent property, and if it can emerge in a toddler it should be able to emerge in a properly designed piece of hardware. And even you can you can do a core dump on that hardware, you'll *never* figure out why it's conscious.

    It would take too much fuel for them to move it away from Earth. They will deorbit it so it re-enters over the Pacific. They didn't do it with Skylab because they didn't have rockets/fuel to control when and where it re-entered.

    What if you plant GM soybeans one year, and on the same land plant regular corn the next year? You're probably going to have a few soybean plants growing from seed that dropped off from the previous year.

    Monsanto has sued over those situations.

    Just because the wires are be superconducting, doesn't remove the need to insulate, etc. Remember there's a bit of a load at the end of that cable (for example, a city) and the return path through you if you touch it is probably an extremely viable alternative. :)

    You're being an idiot. That's like saying that since we can't demonstrate that gravity works between two rocks five million light years away, the theory of gravity isn't science.

    You can easily reproduce evolution in a lab. You can make predictions and test those predictions. None of that can be done with ID.

  16. Re:Shuttle anyone... on US To Shoot Down Dying Satellite · · Score: 1

    They aren't "chasing it down" for two reasons:

    1) It would take way more fuel than they have. It costs $10,000 a pound to put something into space, you think they have enough fuel for a major change in orbits? If it's a spy satellite, it's probably in a polar orbit. If that's the case, it would take almost as much change in velocity to match orbits as it would to get *into* orbit.

    2) What are they going to do if they "chase it down"? Gray tape an 11000 pound satellite down good enough to handle a couple gees during reentry?

    The thing was launched less than two years ago. It would take longer than that to plan a shuttle based recovery mission and build a cradle, and even if it did it'd be cheaper to run the risk and just pay off anyone who gets killed.

  17. Re:Oh bullshit. on US To Shoot Down Dying Satellite · · Score: 1

    They *have* a full tank of hydrazine fuel, half a ton of it. If the thing had *ever* worked they'd use the last bit of it to deorbit into the Pacific Ocean. If they had a self destruct on it, that probably wouldn't be working either.

  18. Re:Target practice or....? on US To Shoot Down Dying Satellite · · Score: 1

    The moon is about 50 times further away from the center of the earth than a satellite in LEO. The effect of earth's gravity is 2500 times less.

    The interceptor will be like Rutan's spaceship. It'll be in space, but it's nowhere near being in orbit.

  19. Re:Still dangerous on US To Shoot Down Dying Satellite · · Score: 1

    Just use a cloud of sand dispersed by a small charge. And the interceptor is just straight up; it doesn't need lateral velocity; it just needs to be in the way. Whatever sand doesn't hit the satellite comes straight down. The goal is to shred it up enough so that everything, including the hydrazine, burns up before it hits the ground.

    Earth sequesters carbon because continental drift recycles carbon back into the planet's interior. Venus doesn't; its crust is much thicker (most of Earth's original crust was removed during the event that formed the moon), and it has no plate techtonics. A little bit of water creating erosion won't cut it.
