    Sure, and Mars has been around for billions. Some of it's atmosphere may have frozen, but vastly more has been blown away.

    A true series hybrid would require a separate generator and motor, rather than being able to use the motor for both. combining the two likely saves cost and weight, but that's just my own speculation.

    A cvt helps, but optimum efficiency for a gasoline engine is when it's running wide open. I'm certain that even with a cvt, the engine in the Prius is not running wide open for any appreciable amount of time.

    Everything I'd read previously claimed it was a true series hybrid, apparently I'm mistaken.

    If the temperature of the earth were higher, it's atmosphere would be a lot thicker too, but that's not the point. Mars cannot hold onto an atmosphere long term because it doesn't have anything to keep it from being blown away. Even if we crashed a bunch of comets into it and increased the temperature by adding greenhouse gasses, the atmosphere would still eventually be blown away by the solar wind.

    Mars lost its atmosphere relatively quickly because it doesn't have a strong magnetic field to protect it from the solar wind. While earths atmosphere would expand somewhat as it warms, it would still be well within the protective confines of the earths magnetosphere. So, no, the earth will not lose its atmosphere with runaway global warming.

    Not all hybrids operate like that, in fact, most don't. What you're talking about is a series hybrid. In a series hybrid (ex: Chevy Volt), only the electric motor is connected to the wheels. The purpose of the gasoline engine is only to turn a generator and produce power for the motor and to charge the batteries. In a parallel hybrid (Ex: Toyota Prius), both the electric motor and the engine are connected to the wheels. As such, the engine must run at variable speeds depending on vehicle speed/gear. The vast majority of available hybrid vehicles are parallel hybrids.

    When we stop using robots to kill people in drone strikes.

    Drones are the future of combat. Not going to change any time soon.

    When we trust the person who programmed the robot (if you do not know who that person is then you cannot trust the robot).

    Trusting strangers is necessary for society to function. You implicitly trust many people just by leaving your house in the morning. Heck, just by living anywhere near other people.

    When we can legally jailbreak our robots to make them do what we want them to do and only what we want them to do.

    If you want to be able to do it, then others can too. I thought you didn't trust random people.

    When robots can be artificially handicapped to ensure they never become as untrustworthy as humans.

    Oh, here's that distrust again. If you can't trust people, then the only robot you would trust is the one you built yourself.

    Earth has a big gravity well, and the vast majority of the valuable metals have sunk down into the core. Asteroids and lighter planetoids would be much better targets.

    If you're not a citizen of any country then you would be your own sovereign. In other words, the only think backing/defending your claim is yourself. That may be enough, as long as there are enough separate resources available to claim. But if the one you claimed is a particularly juicy target, then you better be ready to defend it.

    If this works:
    Positive: Monsanto would no longer be able to sue farmers claiming that they are using Monsanto seed to produce a seed crop to use for planting the next year.
    Negative: If the gene causing infertility is transmitted via pollen, then farmers that try to produce an heirloom seed crop near a field planted with a Monsanto variety would be screwed since their seed crop could end up infertile.

    Elon Musk didn't say that the car never ran out of power. He said that the journalist lied about how much he charged it and about how he drove it. If you only put a gallon of gas into your Chevy Tahoe and try to drive 60 miles, you'll get stuck on the side of the road too.

    Apparently the current Ford F150 can do 756 miles on a single (monstrous 36 gallon) tank, though I wouldn't describe it as a "car". The closest car would be the Mercedes-Benz S400 Hybrid at 694 miles/tank.

    Then again, these are based on mileage ratings. If you hyper-mile, then I suppose you could get far higher ranges than these. The drive wouldn't be very much fun though.

    And in the process, you would get anhydrous magnesium chloride, which could be used to produce magnesium metal. Great for making lightweight vehicles, such as space craft, rovers etc. Of course, you would also end up with a bunch of chlorine. Not sure what a colony would need that for.
