    Well the article says that

    the brother of a man who died without children is permitted and encouraged to marry the widow. However, if either of the parties refuses to go through with the marriage, both are required to go through a ceremony known as halizah, involving a symbolic act of renunciation of their right to perform this marriage.

    So, permitted and encouraged, but not forced into it. Except by god it seems.


  • To add to this, the most closely related passage in the bible is in Genesis 38, where this guy Onan was ordered to have children with his brother’s widow so the child could inherit his brother’s estate.

    This seems to me a bit outside your usual family obligations, and so did the guy because while he engaged in sexual intercourse, he “spilled his seed” on the ground to avoid fulfilling this familial duty.

    God didn’t think much of that and killed him on the spot.

    The tale is usually linked more to the “sin” of contraception, but it seems like a much more pragmatic story: it’s best you knock up your brother’s widow than have everyone start a war over the spoils.

    Not sure if this is a jest, but it isn’t true.

    People move to other countries sometimes with little more than the clothes on their backs - just look at historical immigration to the US.

    If you have the luxury of doing it the proper way - getting a job offer, a place to live, etc - then that’s perfect, but desperate people will do desperate things to survive.

    True, but that’s just one part of the process, and it’s not comparing to the initial energy in the source fuel.

    If nothing else, there’s an absolute efficiency limit from Carnot’s theorem, but in reality it’s much lower, even for the most modern and efficient gas plants, the limit seems to be ~60%, and for nuclear or coal, it’s even lower at around 30-40%.



  • I’m not disputing what the current gold standard is, I’m looking for theoretical possibilities.

    When you say heat, in fusion, most of the energy would be a neutron moving really fast, right? It sucks that it doesn’t have a charge because then it would be really easy, but there’s options here if we get creative.

    Maybe there’s some sort of material yet to be invented that can be slapped by a neutron and “deformed” in a way that causes electrons to shift/make holes and exploit that to make electricity.

    And that free neutron will eventually decay into a proton and electron, and those have a charge, so if we keep them going around a loop until that happens perhaps we could harness it.
