  1. Re:swift, distant and anonymous on Ask Slashdot: What Would Real Space Combat Look Like? · · Score: 1

    Assuming a ferromagnetic solid antimatter is used storage is a breeze. There will be a max G-force rating on the containers and you really don't want to exceed that.
    Straight out of the magnetic confinement into a coil gun would sling it nicely to the baddies.

    Now production of antimatter pellets is what's the difficult part. Humans currently don't produce a lot of energy if you are trying to create pellets of antimatter. If you assume we need 1 kg of antimatter pellets:
    This will contain 9×10^16 J of energy.
    Current production works with an efficiency of 1x10^-10. This means for each joule worth of antimatter 10,000,000,000 joules is used.
    To produce this kg we would currently need 9x10^26 J of energy.
    We are producing about 20,000 TWH of energy each year. This is 72 x 10^18 J.
    Thus, with the current production we would need 12,500,000 years worth of energy.
    Radiating the amount of heat generated while producing (remember the eficciency of 1x10^-10?) away within a year means the surface of the earth would have to be liquid rock and generally not a fun place to be.

    Warning: this is messing with large numbers. Small mistakes in my calculations may result in mistakes of a factor one million or even more. Feel free to correct me if I am wrong.

    Weight (as in mass) doesn't matter in this equasion.Only speed, direction and the gravitational field.
    It's a direct result of the fact that in vacuum a lead ball and a feather fall at the same speed. The speed for it to be caught in orbit is the same for the bullit as it is for the ship you just shot.
    This fact not withstanding: your point is valid, assuming your not batteling close to a neutron star.

    Contary to movie physics water does not freeze in space. It evaporates.
    We can assume the water is at room temperature when launched. In space it doesn't really change temperature much (it can't lose heat fast since there is nothing to lose the heat to. Only radiaton and that is slow as a big dump out of an ant's ass at 20 C). If you take the phase diagram of water you'll see it is a gass in vacuum at 292 K.
    Now the water will cool due to the evaporation itself (boiling costs thermal energy). Thus some of the water will freeze but that'll be more of a snowstorm, not an icicle.

    While there is merrit to your argument I must point out that it's impossible to engage reverse in a manual car at 70 (mph or kmph). There are protections against that.

  8. Re:How well do they handle dangerous situations? on Nevada Approves Rules For Self-Driving Cars · · Score: 3, Interesting

    Here in Europe almost everyone drives manual. Most handle it without making the passengers sick, but maybe the Europeans are more resistant to this. Those who can't controll it seem to consider the clutch as a binary switch. I know one person who also considers the break and the gas pedal to be binary. I haven't sat in the car with her behind the weel but I have seen her on the road, it's terrible.
    By the way: there is a big difference between different clutches. I have an old Opel Astra (1997). The clutch is extremely "long" (it starts to disconnect almost immediately after you touch the pedal, and you have to floor it to disconnect completely. This is a distance of more than 10 cm (4 inches) ) There are many newer cars with "short" clutches (as in "at one angle the clutch starts to disconnect and a cm (half an inch) lower it's disconnected completely"). These are better for racing as they allow fast swiching. They are not comfortable however, as you need to be able to controll the angle of your foot to a greater degree to let it connect smoothly. Most differences between clutch controll can be laid at the feet of the clutch design.

    Libertarian system: big company poisons people, executives are held personally liable and all their possessions are confiscated as part of the settlement.

    It just happens to be each executive is a dumb fuck with a quite fat paycheck (fat for the fact that he doesn't have to do anything, just sign the orders his realy rich "advisors" give him). Firing him will only force the "advisors" to get a new executive. Confiscate all his posessions is not such a big deal.
