  • That’s how the law would treat an adult. “That’s not defending your home, that’s murdering a man who isn’t a threat” is what the adult would be told. They’d want a very good lawyer, they also would have wanted to aim better so there was only their side of the story

    We don’t apply the law like that against children* because children don’t have the ability to control themselves or think before acting that adults have.

    Have a bit of empathy for the kid.

    *Except when it’s very newsworthy







  • Regarding rocket propellant

    Methane is more dense than hydrogen

    Methane makes more thrust than hydrogen

    Hydrogen rockets need to have huge fuel tanks, hydrogen rockets have low thrust - the space shuttle needed boosters to lift off

    Everything in space is a trade off, kerosene is better in all those ways than methane, but you can make methane on Mars. The global warming potential isn’t much as there are so few rocket launches, and hydrogen fuelled rockets use fossil hydrogen (made from fossil methane (aka natural gas)) because it is cheaper than alternatives

    LED was available in the early 2000s I have a few remaining LED lights from about 2001 (and definitely from before 2004) still working. They are much heavier than modern LED lights due to large finned heat sinks and didn’t fit in my nicer light fittings. They weren’t in supermarkets then, you had to look for them, I may have bought them online
